“会话已经开始……"Zend Framework 应用程序中的异常 [英] "session has already been started...." exception in Zend Framework application

问题描述

我在尝试加载 Zend Framework 应用程序时收到此错误:

I get this error when trying to load a Zend Framework application:

我使用 Zend_Auth 并在我的本地服务器上运行良好，但在生产服务器上我收到了前面的错误，但不是每次都如此.

I Use Zend_Auth and on my local server and it works well, but on a production server I get the preceding error, but not every time.

我已检查 .htaccess 文件中的 session.autostart 是否设置为 0.

I have checked that session.autostart is set to 0 in the .htaccess file.

我该如何解决这个错误?

How do I fix this error?

感谢您的回答，但我不会在任何地方使用 session_start().仅与采埃孚合作.

Thank you for your Answer, but I do not user session_start() anywhere. Work only with ZF.

我只在共享服务器上遇到这个问题，在我的本地服务器脚本上运行完美.

I Have this Problem only on shared server, on my local server script works perfectly.

我在此代码中使用 INIT 函数:

I Use INIT Function with this code:

受保护的 $user;

protected $user;

public function init()
{   
    if(!Zend_Auth::getInstance()->hasIdentity())
    {
        $this->_redirect('auth/login');
    }else
    {
        $this->user = Zend_Auth::getInstance()->getIdentity();
    }
}

我已经尝试只在indexAction中设置tis代码，这样其他action就不用去破解Auth了...但是还是有问题.

I allready try to set tis code only in indexAction, so that other actions do not have to chack the Auth... but still have problems.

有没有办法在 Action 中设置不检查会话或类似这样的想法?

Ist there a way to set in an Action to do not check about session or somethink like this?

最好的问候

推荐答案

事情就是这样.Zend_Auth 尝试开始一个新的会话，因为 Zend_Session::start() 还没有被调用.

It's what it says it is. Zend_Auth tries to start a new session, since Zend_Session::start() has not yet been called.

问题是必须在会话开始之前调用 Zend_Session::start().但是，由于 session.autostart 是 0(顺便说一句，这是在 php.ini 中而不是 .htaccess 中)，您可能已经编写了 session_start();某处.您不能这样做，因为 ZF 希望完全控制会话，即您不应直接访问全局会话变量.

The problem is that Zend_Session::start() has to be called before a session is started. But, since session.autostart is 0 (btw this is in php.ini not .htaccess), you have probably written session_start(); somewhere. You're not allowed to do that, since ZF wishes to have full control over sessions, i.e. you shouldn't access the global session variable directly.

要解决它，请在您的代码文件中搜索 session_start() 和其中之一

To solve it, search your code files for session_start() and either

1. 删除所有出现，但只有一个.要注意它是否已经启动，请设置 error_reporting(E_ALL|E_STRICT);
2. 在所有地方用 Zend_Session::start(); 替换它

如果你不能找到所有的出现，找到一个 session_start();这会困扰您的 Zend_Auth::getInstance()->hasIdentity() 并使用以下代码段快速解决问题

If you can't find all occurrences, find the one session_start(); that bothers your Zend_Auth::getInstance()->hasIdentity() and solve the problem quick n' dirty with the following snippet

try {
    Zend_Session::start();
} catch(Zend_Session_Exception $e) {
    session_start();
}

如果您在整个应用程序中使用 ZF，我会选择 2)

If you're using ZF in your whole application, I would go with 2)
