CSRF token 无法被验证. ----Yii连接数据库后数据库错误日志报错

CSRF token 无法被验证.

我使用的是mongodb+ yii1.1

What is CSRF, please see the details here.  http://en.wikipedia.org/wiki/Cross-site_request_forgery

In Yii, how to start the CSRF authorization? It is very easy to do that.

Just add this to main.php

'components'=>array(
    'request'=>array(
    　　'enableCsrfValidation'=>true,
    ),
),  

And then, do something else to send a request to the server, you have to provide the  YII_CSRF_TOKEN ( the browser will do for us when click a link), otherwise, you will get this message

The CSRF token could not be verified.

when you post a form, if you do not use CActiveForm or its children, you have to provide a hidden field to store the YII_CSRF_TOKEN.

<input type="hidden" name="YII_CSRF_TOKEN" value="<?php echo Yii::app()->request->csrfToken; ?>" />  

If you use CActiveForm or its children, you just use the same code no matter you set enableCsrfValidation to true or false.

如果你使用CActiveForm类或其继承的子类进行创建表单时，在POST提交数据的时候会有一个$_POST['YII_CSRF_TOKEN'] 字段，让程序识别这是程序合法的提交数据。

<?php $form=$this->beginWidget('CActiveForm'); ?>  
<--表单信息-->
<?php $this->endWidget(); ?>

顺便补充一下：在使用CActiveForm时，可以自定义设置参数，

<?php $form = $this->beginWidget('CActiveForm', array(
　　'id' => 'register-form',
　　'action' => ['test/register'],
));?>

通过action选项设置当前表单数据的提交处理url. 详细参数可以参考参考手册
