重定向后我的 $_SESSION 是空的，为什么? [英] After redirection my $_SESSION is empty, why?

问题描述

我运行了以下测试以验证我的代码是否正常工作:

I run followed test to verify my code working properly:

curl -L -i -X POST -d 'json={"orderBy":0,"maxResults":50}' http://mysite.com/ctlClient/

curl -L -i -X POST -d 'json={"orderBy":0,"maxResults":50}' http://mysite.com/ctlClient/

我调用:http://mysite.com/ctlClient/index.php:

        session_unset();
        session_start();

        //pass data to _SESSION
        foreach($_POST as $key => $value){
           $_SESSION[$key] = $value;
         }
        // redirect to `/fwf/online/index.php`
        ctlGotoSameDomain("/fwf/online/");

重定向后，我调用/fwf/online/index.php:

 <?php

session_start();

 ....

class fwfOnline {


  public function __construct() {

         msqLogFile('test/test_max',$_SESSION);

        // here is my problem, $_SESSION is empty, :(

        $this->json = isset($_SESSION['json']) ? $_SESSION['json'] : null;
        global $gConfig;
        if ($gConfig['soapDebug'])
            msqLogFile("fwf/post", Array('post' => 'Request: '.$this->json));
        $this->response = $this->getResponse();
        echo $this->response;
    }

....

在来自 mysite.com/ctlClient/index.php 的日志中，我看到 $_SESSION 有数据但在 /fwf/online/index.php 中它是空的.

In logs from mysite.com/ctlClient/index.php I see that $_SESSION has data but in /fwf/online/index.php its empty.

谁能告诉我我错过了什么?

Can someone tell me what did i miss?

谢谢，

我打印了两个会话 ID，结果有所不同:

I printed both session IDs and got difference:

"2013-07-05 09:44:31","Session ID: ihpfs1skrp792gncgancb02516"
"2013-07-05 09:44:31","Session ID: tp6ejtl1tj9bigrgsi3jt6h9a1"

为什么会这样?

[修复]

关于 @rr- 回答我发现了问题，

Regards to @rr- answer I found the problem,

我需要将 -b 添加到我的脚本中以启用 cookie.CURL 默认不使用它们，这个问题会导致会话 ID 问题.

I need to add -b to my script to enable the cookies. CURL by default doesn't use them and this issue caused to session ID problem.

谢谢rr-

推荐答案

确保您已在目标页面中启动会话:/fwf/online/index.php.

Make sure you have started session in the target page: /fwf/online/index.php.

您还可以在两个页面上检查 session_id() 的返回值.该值应该相同，如果即使您在两个页面上都调用了 session_start ，这可能意味着三件事:

You can also check return value of session_id() on both pages. The value should be the same, if it isn't even though you have called session_start on both pages, this can mean three things:

1. 无论您调用 session_write_close 有效地导致创建新会话并忘记所有以前的数据，
2. PHP 无法访问它应该在服务器上存储会话数据的目录(它发生了！)，
3. ...或者用户禁用了 cookie，从而使他的浏览器无法保留会话 ID.

1. Either you call session_write_close which effectively leads to creating new sessions and forgets all previous data,
2. PHP cannot access directory where it should store session data on the server (it happens!),
3. ...or user has disabled cookies, thus making his browser unable to keep session ID.

我认为第三个选项很可能是问题的原因.

I think the third option is most likely the reason of the problem.
