yii2 配置加速 – N个配置文件生成一个配置文件

yii2的配置方式是N个配置文件,最终通过merge函数合并成一个php数组,如果只有几个配置文件,不会占用太多资源,如果像fecshop这类电商系统,有大量的配置文件,因此需要合并N个配置文件成一个配置文件,具体实现如下:

首先新建文件@app/merge_config.php 设置可写权限, 然后新建文件 @app/web/index-merge-config.php,将index.php的内容复制过来,在 代码:$config = yii\helpers\ArrayHelper::merge函数后面,添加下面的代码,这些代码的用处是将$config数组的内容重新写成php代码保存到文件@app/merge_config.php中

$str = '<?php '.PHP_EOL;
$str .= 'return '.PHP_EOL;

function toPhpCode($arr,$i=0){
  $i++;
  $tb_i = $i*4;
  $tb = ($i-1)*4;
  $tb1_str = '';
  $tb2_str = '';
  for($j=0;$j<$tb;$j++){
    $tb1_str .= ' ';
  }
  for($jj=0;$jj<$tb_i;$jj++){
    $tb2_str .= ' ';
  }
  $mystr = '';
  if(is_array($arr) && !empty($arr)){
    $mystr .= PHP_EOL .$tb1_str.'['.PHP_EOL;
    $t_arr = [];
    foreach($arr as $k => $v){
      $key 	= '';
      $value 	= '';
      if(is_string($k)){
        $key = "'".$k."'";
      }else{
        $key = $k;
      }
      if(is_array($v) && !empty($v)){
        $value = toPhpCode($v,$i);
      }else if(is_array($v) && empty($v)){
        $value = '[]';
      
      }else{
        if(is_string($v)){
          $value = "'".$v."'";
        }else if(is_bool($v)){
          if($v){
            $value = 'true';
          }else{
            $value = 'false';
          }
        }else{
          if(is_null($v)){
            $v = "''";
          }
          $value = $v;
        }
        
      }
      $t_arr[] = $tb2_str.$key."=>".$value;
    }
    $mystr .= implode(','.PHP_EOL,$t_arr);
    $mystr .= PHP_EOL .$tb1_str.']'. PHP_EOL;
  }
  return $mystr;
}


$str .= toPhpCode($config);
$str .= ';';

echo 'generate merge config file success';
file_put_contents('../merge_config.php', $str);
echo 'generate merge config file success';

执行这个文件后,就会将$config数组的内容,以php代码的方式写入到merge_config.php,这样就生成了单文件配置。

在index.php中加载单文件配置

$use_merge_config_file = true;

if($use_merge_config_file){
  $config = require('../merge_config.php');
}else{
  $config = yii\helpers\ArrayHelper::merge(
    require(__DIR__ . '/../../common/config/main.php'),
    require(__DIR__ . '/../../common/config/main-local.php'),
    require(__DIR__ . '/../config/main.php'),
    require(__DIR__ . '/../config/main-local.php'),
    # fecshop services config
    require(__DIR__ . '/../../vendor/fancyecommerce/fecshop/config/fecshop.php'),
    # fecshop module config
    require(__DIR__ . '/../../vendor/fancyecommerce/fecshop/app/appfront/config/appfront.php'),
    
    # thrid part confing
    
    # common modules and services.
    require(__DIR__ . '/../../common/config/fecshop_local.php'),
     
    # appadmin local modules and services.
    require(__DIR__ . '/../config/fecshop_local.php')
    
  );
}

这样就完成了。

重启nginx,就可以访问https了

2自动续签

lets encrypt证书有三个月的到期时间。可以自动renew,步骤如下:

官方资料:https://certbot.eff.org/docs/using.html?highlight=renew#renewing-certificates

改写到期更新时间

vim /etc/letsencrypt/renewal/fecshop.appfront.fancyecommerce.com.conf

fecshop.appfront.fancyecommerce.com.conf是您生成的名字,这个根据您自己域名,不是我的这个名字,打开这个文件,
将第一行的注释去掉,修改为89days

renew_before_expiry = 89 days
version = 0.13.0

89days代表,多少天之前算过期,证书过期时间为90天,如果我设置了89,那么第二天就需要renew了,
如果您设置了30天,那么就是2个月后需要renew,如果时间没到,renew会提示失败。

改好文件后,进入letsencrypt 文件夹,执行

./certbot-auto renew   --force-renewal   --pre-hook "/etc/init.d/nginx stop" --post-hook "/etc/init.d/nginx start"

`–force-renewal`: 代表强制renew
`–pre-hook`: 是nginx关闭的命令,因为renew需要关闭nginx
`–post-hook`: 是nginx开启的命令,搞完证书后,开启nginx

自动续签可以使用crontab来完成,在linux中执行  crontab -e
添加代码:(www/web_logs/letsencry.log 为日志文件,您需要新建这个文件并设置可写)

06 06 * * * /www/web/test/lets/certbot-master/certbot-auto renew   --force-renewal   --pre-hook "/etc/init.d/nginx stop" --post-hook "/etc/init.d/nginx start" >> /www/web_logs/letsencry.log 2>&1

3.开启http2

可以更快的加载https,关于http2的资料为:http://www.jianshu.com/p/47d02f10757f

nginx安装的时候需要添加:

./configure   --with-http_v2_module

然后在nginx的ssl配置将listen 443 ssl ;改为:

listen 443 ssl http2;

这样就开启http2了,http2可以更快的加载。

http2的资料:

http://www.infoq.com/cn/news/2015/02/https-spdy-http2-comparison/

4.强制使用https,http访问进行跳转

server {
           listen       80;
           server_name  fecshop.appfront.fancyecommerce.com fecshop.appfront.es.fancyecommerce.com;
           rewrite ^(.*)$ https://$host$1 permanent;

}

Yii2 账号登录需要注意的地方 – 生成密码函数generatePasswordHash很慢

Yii2默认的用户组件,在登录用户,都需要先把密码加密,然后去数据查询核对,

密码加密的代码如下:

\Yii::$app->security->generatePasswordHash($password);

Yii2/base/Security.php

public function generatePasswordHash($password, $cost = null)
    {
        if ($cost === null) {
            $cost = $this->passwordHashCost;
        }

        if (function_exists('password_hash')) {
            /** @noinspection PhpUndefinedConstantInspection */
            return password_hash($password, PASSWORD_DEFAULT, ['cost' => $cost]);
        }

        $salt = $this->generateSalt($cost);
        $hash = crypt($password, $salt);
        // strlen() is safe since crypt() returns only ascii
        if (!is_string($hash) || strlen($hash) !== 60) {
            throw new Exception('Unknown error occurred while generating hash.');
        }

        return $hash;
    }

最后,发现代码耗时卡在   $hash = crypt($password, $salt);

也即是php的crypt函数。在我的linux上面耗费了520ms

现在的系统验证码,有很多包,是可以破的,玩爬虫的,都有付费的机器学习类的破验证码,普通的文字数字验证码,很轻松能破,验证码一破,账号注册登录被爬虫搞起来,很快就把php进程堵死了。

如果你的系统,登录注册很频繁,建议重写一下这个函数,不过是否在某些方面存在安全性,这个我说不好,自己取舍一下。

上面是我测试的结果,大家有兴趣可以都测试试试。

Mongodb 数组型索引报错:WiredTigerIndex::insert: key too large to index, failing

mongodb支持很多种索引,参看官网:https://docs.mongodb.com/manual/indexes/#index-use

创建一个简单索引: db.collection.createIndex({‘name’:1})
这种方式的索引,默认是比较小的,如果值过长就会报错WiredTigerIndex::insert: key too large to index, failing
可以该种hasded的方式 db.collection.createIndex({‘name’:’hashed’}),
如果name是数组格式,而不是字符串,就不能用hashed的索引格式了,这样,我们需要通过另外的方法来解决

https://docs.mongodb.com/manual/reference/parameters/#param.failIndexKeyTooLong

通过设置参数 failIndexKeyTooLong 为false来解决,文档里面有具体的方法,

我的mongodb的启动方式为:

/usr/bin/mongod -f /etc/mongod.conf

我在 /etc/mongod.conf 配置文件中添加下面的配置

setParameter:
  failIndexKeyTooLong: false

关于mongodb的config的详细可以参看地址:

https://docs.mongodb.com/manual/reference/configuration-options/

通过上面的方式,重启mongodb,解决了我的问题,不报错了

 

Fecshop 环境部署 以及 安装步骤

一:安装Fecshop的环境部署:

本文只讲解在Linux下面部署安装Fecshop的步骤,在windows下面不做阐述(需要安装的东西太多,windows下面部署我没有玩过,遇到的问题也不能提供好的解决方式,故而不做阐述),对于Linux开发环境,可以在window下虚拟一个linux,文档参看: 关于vagrant的安装详情参看

本文是在centos 6下面安装环境的详细步骤。

1.更新linux

yum update

2.yum安装基础

yum  install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel libtool* zlib-devel libxml2-devel libjpeg-devel libpng-devel libtiff-devel fontconfig-devel freetype-devel libXpm-devel gettext-devel curl curl-devel pam-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers gzip  make bzip2bzip2-devel pcre-devel wget ncurses-devel cmake make perl
yum -y install gcc automake autoconf libtool make   gcc-c++ glibc  libmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel lib
yum -y install gcc gcc-c++
yum install  libevent*  libtool* autoconf* libstd* ncurse* bison* openssl*  

1.2 如果在安装 libevent*的时候报错:

libevent2-devel conflicts with libevent-devel-1.4.13-4.el6.x86_64

则使用下面的安装方式

yum install  libevent2  libtool* autoconf* libstd* ncurse* bison* openssl*

查看文件是否存在

ls /usr/lib/libncurses.so

如果找不到,则

find / -name ‘libncurses.so’

我找到的文件如下:

/usr/lib64/libncurses.so

增加快捷方式

ln -s /usr/lib64/libncurses.so /usr/lib/libncurses.so

在开始安装之前,需要下载下面的这些软件,你可以通过我的打包一次下载下面,解压到您的/tools文件夹下面使用,所有的软件的下载地址为(百度云盘):

http://pan.baidu.com/s/1kVwRD2Z,进入下载:linux环境安装所需软件.zip

当然您可以自己去相应官网下载相应的软件。

2.开始安装mysql

安装教程为:

linux 安装mysql5.6

在上述安装中,遇到yum安装的地方可以直接忽略掉,因为上面已经安装了。

3.安装php 以及扩展

php有php5和php7,两种版本,下面都给予了安装文档,建议安装php7,性能比较快

3.1 php7的安装

安装php7以及扩展教程为:

php 7 环境安装

3.2 php5的安装

3.2.1 安装php5.4教程为:

Linux 安装php 5.4 – yii2 环境

在上述安装中,遇到yum安装的地方可以直接忽略掉,因为上面已经安装了。

3.2.2 安装php5.4的扩展

安装教程为:

Linux php 扩展安装 mongo ,redis ,soap,imap,pdo_mysql,oauth

注意:上面的安装php5.4扩展的教程中,有一个跳转到mongodb的教程,只需要执行里面的步骤1, 2, 3, 4.2 这几个步骤即可。步骤1,2,3是安装mongodb的步骤,步骤4.2是安装mongodb扩展的步骤,不需要安装php-mongo扩展

安装完成后重启php

/etc/init.d/php-fpm restart

 

5.安装redis

安装教程为:

yii2 – redis 配置

注意:只需要执行步骤1,2就可以了。

redis关闭命令:/etc/init.d/redis_6379 stop

redis开启命令:/etc/init.d/redis_6379 start

6.安装nginx

安装教程为:

Linux – 安装nginx – 搭配YII2环境

关于nginx的配置,您可以在上面,在百度云盘下载将环境配置里面

https://pan.baidu.com/s/1kVwRD2Z

下载 “环境配置文件.rar”,解压后,将里面的文件覆盖到linux的根目录。这里面也有php的配置,覆盖即可。

然后在 vim /usr/local/nginx/conf/conf.d/default.conf 修改里面的配置即可。

7.php设置快捷方式:

ln -s  /usr/local/php/bin/php  /usr/bin/php

 

8.linux一般安装在内部或者远程服务器,当然也可以通过vagrant安装虚拟机的方式,我们开发的时候都不需要用vim编辑,喜欢win下面的编辑器,那么可以通过下面的方式,通过编辑器的ftp功能远程加载文件的方式,教程如下:

Yii2 User cookie 登录原理 2

对于yii2中用户登录,我们可在user组件中设置session的超时时间,另外我们在session中设置session的超时时间,他们的关系是如何呢?
下面是他们的配置:
session组件的配置:

'session' => [
      /**
       * use mongodb for session.
       */
      /*
      'class' => 'yii\mongodb\Session',
      'db' => 'mongodb',
      'sessionCollection' => 'session',
      */
      'class' => 'yii\redis\Session',
      'timeout' => 5,
    ],

User组件的配置:

'user' => [
      'class' 			=> 'fecshop\yii\web\User',
      'identityClass' 	=> 'fecshop\models\mysqldb\Customer',
      # 是否cookie 登录。
      /**
       * @var boolean whether to enable cookie-based login. Defaults to false.
       * Note that this property will be ignored if [[enableSession]] is false.
       */
      'enableAutoLogin' 	=> false,
      'authTimeout' 		=> 86400,
    ],

当session的超时时间为5秒,user的enableAutoLogin设置为false(不使用cookie,而使用session的验证登录方式),超时时间为86400秒,通过结果验证发现,5秒后在刷新页面,发现登录状态失效了,需要重新登录

让把session的超时时间设置为86400,user中的authTimeout设置为5秒,通过结果验证发现,5秒后在刷新页面,发现登录状态失效了,需要重新登录。

结果说明:User 组件,在enableAutoLogin设置为false的情况下(不使用cookie,而使用session的验证登录方式),取的是他们的最小的那个值,原因如下:

public function login(IdentityInterface $identity, $duration = 0)
   {
       if ($this->beforeLogin($identity, false, $duration)) {
           $this->switchIdentity($identity, $duration);
           ....

 

public function switchIdentity($identity, $duration = 0)
    {
        .....
        if ($identity) {
            $session->set($this->idParam, $identity->getId());
            if ($this->authTimeout !== null) {
                $session->set($this->authTimeoutParam, time() + $this->authTimeout);
            }
            if ($this->absoluteAuthTimeout !== null) {
                $session->set($this->absoluteAuthTimeoutParam, time() + $this->absoluteAuthTimeout);
            }
            if ($duration > 0 && $this->enableAutoLogin) {
                $this->sendIdentityCookie($identity, $duration);
            }
        }
    }

identity的id保存一个session,相对当前超时时间保存到一个session,绝对超时时间保存一个session,一共三个session,他们的失效时间为session的配置中的失效时间,因此,如果session组件中配置的时间到期,就无法取出来值,

protected function renewAuthStatus()
    {
        $session = Yii::$app->getSession();
        $id = $session->getHasSessionId() || $session->getIsActive() ? $session->get($this->idParam) : null;

        if ($id === null) {
            $identity = null;
        } else {
            /* @var $class IdentityInterface */
            $class = $this->identityClass;
            $identity = $class::findIdentity($id);
        }

上面代码取出来的$id为空,因此session的超时值首先决定一个大范围,

然后user组件在这个范围内设置用户登录状态的超时时间,如果这个值超出session设置的范围,则session的超时值决定登录状态的超时时间。

另外,session的超时时间,默认为相对超时时间,譬如:你设置的为10秒超时,但是你间隔9秒刷新一次,登录状态会一直保持,如果通过配置更改为绝对超时时间,譬如设置绝对绝对超时时间为20秒,那么9秒刷新一次页面,20秒后,登录状态为失效。

if ($this->authTimeout !== null) {
               $session->set($this->authTimeoutParam, time() + $this->authTimeout);
           }
           if ($this->absoluteAuthTimeout !== null) {
               $session->set($this->absoluteAuthTimeoutParam, time() + $this->absoluteAuthTimeout);
           }
           if ($duration > 0 && $this->enableAutoLogin) {
               $this->sendIdentityCookie($identity, $duration);
           }
if ($identity !== null && ($this->authTimeout !== null || $this->absoluteAuthTimeout !== null)) {
            $expire = $this->authTimeout !== null ? $session->get($this->authTimeoutParam) : null;
            $expireAbsolute = $this->absoluteAuthTimeout !== null ? $session->get($this->absoluteAuthTimeoutParam) : null;
            if ($expire !== null && $expire < time() || $expireAbsolute !== null && $expireAbsolute < time()) {
                $this->logout(false);
            } elseif ($this->authTimeout !== null) {
                $session->set($this->authTimeoutParam, time() + $this->authTimeout);
            }
        }

 

通过上面的代码可以看出,绝对超时时间设置后,如果相对时间不失效,绝对时间失效,那么最终的结果是登录状态失效。

如果enableAutoLogin后,如果登录状态判断失效后,可以通过cookie重新恢复session登录状态,如果登录状态没有失效,cookie的失效时间会更新,也就是当前时间+失效时间为cookie的当前失效时间。

 

最后,需要说明的是,cookie的登录状态的保持的原理为:

if ($this->enableAutoLogin) {
           if ($this->getIsGuest()) {
               $this->loginByCookie();
           } elseif ($this->autoRenewCookie) {
               $this->renewIdentityCookie();
           }
       }

当session失效后,如果cookie开启就会通过cookie获取当前用户信息,最终的登录状态,还是通过session来体现,cookie的作用是在session失效,但是cookie没有实现的情况下起作用,恢复session的登录状态。

 

Yii2 User cookie 登录原理

本文是在session登录畅通无阻的前提下,首先要先搞好session登录,这个在这里不做叙述,好多session登录的文章。本文叙述cookie登录的原理和使用

1.具体实现:

1.1 cookie登录配置config方面,配置好的代码如下:

'components' => [
    'user' => [
       'identityClass' => 'fecshop\models\mysqldb\Customer',
       'enableAutoLogin' => true,
       'authTimeout' => 3600,
       ],
],

enableAutoLogin设置为true,就会使用cookie登录,如果设置了enableAutoLogin,那么下面的超时时间authTimeout就会无效,因为这个参数是session的超时时间,不过,我们可以在登录的时候,超时时间也从这个配置参数读取,譬如下面的函数参数$duration,可以从这里读取,如果这样,就会有效。

$duration = \Yii::$app->user->authtimeout;
\Yii::$app->user->login($this->getCustomer(), $duration);

上面的结论通过代码解释,如下:

public function login(IdentityInterface $identity, $duration = 0)
    {
        if ($this->beforeLogin($identity, false, $duration)) {
            $this->switchIdentity($identity, $duration);
            $id = $identity->getId();
            $ip = Yii::$app->getRequest()->getUserIP();
            if ($this->enableSession) {
                $log = "User '$id' logged in from $ip with duration $duration.";
            } else {
                $log = "User '$id' logged in from $ip. Session not enabled.";
            }
            Yii::info($log, __METHOD__);
            $this->afterLogin($identity, false, $duration);
        }

        return !$this->getIsGuest();
    }

查看 $this->switchIdentity($identity, $duration);

public function switchIdentity($identity, $duration = 0)
    {
        $this->setIdentity($identity);

        if (!$this->enableSession) {
            return;
        }

        /* Ensure any existing identity cookies are removed. */
        if ($this->enableAutoLogin) {
            $this->removeIdentityCookie();
        }

        $session = Yii::$app->getSession();
        if (!YII_ENV_TEST) {
            $session->regenerateID(true);
        }
        $session->remove($this->idParam);
        $session->remove($this->authTimeoutParam);

        if ($identity) {
            $session->set($this->idParam, $identity->getId());
            if ($this->authTimeout !== null) {
                $session->set($this->authTimeoutParam, time() + $this->authTimeout);
            }
            if ($this->absoluteAuthTimeout !== null) {
                $session->set($this->absoluteAuthTimeoutParam, time() + $this->absoluteAuthTimeout);
            }
            if ($duration > 0 && $this->enableAutoLogin) {
                $this->sendIdentityCookie($identity, $duration);
            }
        }
    }

查看:$this->sendIdentityCookie($identity, $duration);

protected function sendIdentityCookie($identity, $duration)
    {
        $cookie = new Cookie($this->identityCookie);
        $cookie->value = json_encode([
            $identity->getId(),
            $identity->getAuthKey(),
            $duration,
        ], JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
        $cookie->expire = time() + $duration;
        Yii::$app->getResponse()->getCookies()->add($cookie);
    }

通过一层层的函数可以看到,cookie的超时时间是从login()函数中读取出来的,

而不是从\yii\web\User的authTimeout变量读取。最后传递给sendIdentityCookie($identity, $duration)方法,进而设置cookie的超时时间。

另外配置中开启了enableAutoLogin,但是在调用login方法的时候没有设置超时时间变量$duration,同样不会设置cookie,进而配置 enableAutoLogin 无效,下面是代码解释:

public function switchIdentity($identity, $duration = 0){    函数中的代码
if ($duration > 0 && $this->enableAutoLogin) {
$this->sendIdentityCookie($identity, $duration);
}

}
可以看到,如果超时时间为0,那么不会执行设置cookie的方法

public function sendIdentityCookie($identity, $duration); 进而不会设置cookie

 

1.2 代码改进:

 

参考代码:

public function getCustomer(){
      if($this->_customer === null){
        $this->_customer = Customer::findByEmail($this->email);
      }
      return $this->_customer;
      
    }
    
    public function login($duration = 86400)
    {
      if ($this->validate()) {
        //return \Yii::$app->user->login($this->getAdminUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
        return \Yii::$app->user->login($this->getCustomer(), $duration);
      } else {
        return false;
      }
    }

在上面的代码,默认cookie的过期时间为86400秒,这样默认就不会cookie超时
如果我我调用:

$model = new CustomerLogin;
$model->email = $data['email'];
$model->password = $data['password'];
$loginStatus = $model->login(0);

由于过期时间填写为0,因此,即使在user组件中开启配置enableAutoLogin=true,
cookie也不会生效。

另外,我如果从\yii\web\User的authTimeout变量读取。来设置cookie的超时时间,也是一个不错的选择,代码如下:

public function login($duration = 0)
    {
    if(!$duration){
      if(Yii::$app->user->authTimeout){
        $duration = Yii::$app->user->authTimeout;
      }
    }
    if ($this->validate()) {
            //return \Yii::$app->user->login($this->getAdminUser(), $this->rememberMe ? 3600 * 24 * 30 : 0);
      return \Yii::$app->user->login($this->getCustomer(), $duration);
        } else {
            return false;
        }
    }

 

2. cookie超时时间刷新。

在默认的情况下,如果登录成功账户,每次请求访问Yii::$app->user->identity,都会刷新cookie的超时时间,设置自动更新的变量为:

public $autoRenewCookie = true;

该变量默认为true,所以不需要在配置中设置这个变量,使用默认就好。

cookie超时时间刷新的原理解释,下面是详细代码:

执行Yii::$app->user->identity,对应的是下面的函数

public function getIdentity($autoRenew = true)
   {
       if ($this->_identity === false) {
           if ($this->enableSession && $autoRenew) {
               $this->_identity = null;
               $this->renewAuthStatus();
           } else {
               return null;
           }
       }

       return $this->_identity;
   }

会执行renewAuthStatus()方法

protected function renewAuthStatus()
   {
       $session = Yii::$app->getSession();
       $id = $session->getHasSessionId() || $session->getIsActive() ? $session->get($this->idParam) : null;

       if ($id === null) {
           $identity = null;
       } else {
           /* @var $class IdentityInterface */
           $class = $this->identityClass;
           $identity = $class::findIdentity($id);
       }

       $this->setIdentity($identity);

       if ($identity !== null && ($this->authTimeout !== null || $this->absoluteAuthTimeout !== null)) {
           $expire = $this->authTimeout !== null ? $session->get($this->authTimeoutParam) : null;
           $expireAbsolute = $this->absoluteAuthTimeout !== null ? $session->get($this->absoluteAuthTimeoutParam) : null;
           if ($expire !== null && $expire < time() || $expireAbsolute !== null && $expireAbsolute < time()) {
               $this->logout(false);
           } elseif ($this->authTimeout !== null) {
               $session->set($this->authTimeoutParam, time() + $this->authTimeout);
           }
       }

       if ($this->enableAutoLogin) {
           if ($this->getIsGuest()) {
               $this->loginByCookie();
           } elseif ($this->autoRenewCookie) {
               $this->renewIdentityCookie();
           }
       }
   }

如果enableAutoLogin开启,如果登录就会执行renewIdentityCookie方法。

protected function renewIdentityCookie()
   {
       $name = $this->identityCookie['name'];
       $value = Yii::$app->getRequest()->getCookies()->getValue($name);
       if ($value !== null) {
           $data = json_decode($value, true);
           if (is_array($data) && isset($data[2])) {
               $cookie = new Cookie($this->identityCookie);
               $cookie->value = $value;
               $cookie->expire = time() + (int) $data[2];
               Yii::$app->getResponse()->getCookies()->add($cookie);
           }
       }
   }

该方法会重新设置超时时间,通过上面的几个函数知道了原理,那么问题来了,如果我登录了用户,超时时间设置的为10秒,我开始浏览器文章或者干其他的,每次访问间隔3秒,如果这些页面都没有执下面的行代码:

Yii::$app->user->identity

那么,10秒后,用户登录状态就会被超时,需要重新登录,(有一些间接的方法也会执行上面的代码,譬如Yii::$app->user->isGuest ,就会间接调用执行Yii::$app->user->identity,这种情况下不会超时)。

public function getIsGuest()
   {
       return $this->getIdentity() === null;
   }

 

因此,如果登录状态要持久下去,那么为了保持登录状态,每个页面请求后,都需要执行Yii::$app->user->identity,然后cookie的超时时间就会更新,这样3秒请求一次,登录状态会一直保持下去。

上面是yii2 cookie使用过程中要注意的一些问题。总体来说还是不错,但在实际过程中,还需要结合一下其他,譬如cart 和customer login都使用cookie,超时时间要一致,那么,cart和customer的cookie超时时间要一致,并且,在每次调用Yii::$app->user->identity,都必须执行更新cart的cookie超时时间,因此,需要重写Yii\web\User。

下一个章节介绍实现的具体步骤。

 

在yii2 advanced中使用console

console 是命令行操作,对于frontend和backend是基于web的操作,最终的结果是一样的,都是传递数据给php,下面做一个例子:

1.安装frontend ,然后执行init,可以参看这里:

Yii2 – 安装高级模板 advanced project template

2.新建文件夹/console/controllers/script,然后新建文件TestController.php

3.编辑文件内容:

<?php

namespace console\controllers\script;
use Yii;
use yii\console\Controller;
use fec\helpers\CDate;
use fec\helpers\CConfig;
use appadmin\code\Website\models\WebsiteBaseInfo;
class TestController extends Controller
{
        public $_mongodbdb;


        public function actionGetbegindate(){
                echo '2015-05-20';

        }


        public function actionCreatecollindexer(){
                echo 'create Coll index success';

        }
        public function actionMy($param1,$param2=''){
                echo "param1:".$param1;
                echo "param2:".$param2;
        }


}

4.回到yii advanced的根目录执行:

[root@services datacenter_1000]# ./yii script/test/my  111  2222
param1:111param2:2222
[root@services datacenter_1000]#

解读:

script/test/my 这个和web一样,对应到上面创建的TestController的 actionMy()方法,111为传递的第一个参数,222给传递的第二个参数。

到这里,基本就一个helloworld就写好了,其他的和web没有什么两样。

5.在模块中使用console:(下面是一个在模块TA中使用console的例子)

'modules'=>[

'ta' => [
        'class' => 'appadmin\code\Ta\Module',
        'params'=> [
            'channel_type' => [
                'ppc'    => 'PPC类型',
            ],
        ],
    ],

]

在ta模块的Module中添加代码:

<?php
namespace appadmin\code\Ta;
use Yii;
class Module extends \fec\AdminModule
{
   
    public function init()
    {
    //echo 1;exit;
    # 以下代码必须指定
    # web controller
    if (Yii::$app instanceof \yii\web\Application) {
      $this->controllerNamespace 	= 	__NAMESPACE__ . '\\controllers';
    # console controller
    } elseif (Yii::$app instanceof \yii\console\Application) {
      $this->controllerNamespace 	= 	__NAMESPACE__ . '\\console';
    }
    
    parent::init();  
    
    }
}

通过上面判断是console的application还是web的application,取执行相应的controller

譬如我写的一个导入excel的脚本(在ta模块中):

<?php
namespace appadmin\code\Ta\console\import;
use Yii;
use appadmin\code\Ta\models\WebsiteChannel;
use yii\console\Controller;
use fec\helpers\CExcel;

class ExcelController extends Controller
{
  public function actionChannel(){
    $channel_excel_file = Yii::getAlias('@appta/var/import/channel.xlsx');
    $arr = CExcel::getExcelContent($channel_excel_file);
    //var_dump($arr);
    $i = 0;
    foreach($arr as $one){
      $i++;
      if($i == 1){
        continue;
      }
      $channel 		= trim($one['A']);
      $channel_child 	= trim($one['B']);
      $domain 		= trim($one['C']);
      
    
      $one = WebsiteChannel::find()->where([
        'channel' => $channel,
        'channel_child' => $channel_child,
        'domain' => $domain,
      ])->one();
      if(!$one['id']){
        $WebsiteChannel = new WebsiteChannel;
      }else{
        continue;
      }
      //SEO>SEM>KOL>SNS
      
      
      $WebsiteChannel->channel 		= $channel;
      $WebsiteChannel->channel_child  = $channel_child;
      $WebsiteChannel->domain 		= $domain;
      
      $WebsiteChannel->created_person = 'program_script';
      $WebsiteChannel->save();
      unset($WebsiteChannel);
      
    }
  }
  
  
  
  
}

我新建一个shell文件

appta/shell/import/channel.sh,内容为:

#!/bin/sh
DIR=$(cd `dirname $0`; pwd)
$DIR/../../../yii ta/import/excel/channel

然后执行这个shell就会执行上面的模块Ta里面的console部分。

 

Yii2 Mongodb ActiveRecord 添加索引

public static function create_index(){
  $indexs = [
    ['cid' => -1],
    ['market_person' => -1],
    ['created_at_date' => -1,'market_person' => -1],
  ];
  
  $options = ['background' => true, 'socketTimeoutMS' => 300000];
  foreach($indexs as $columns){
    self::getCollection()->createIndex($columns,$options);
  }
}

$indexs里面的每一个数组就是一个索引,

$options 里面的background代表后台执行的意思,因为添加索引,如果不加这个选项,如果表很大,要执行几十分钟,那么库会被加锁。
