必须登录两次。 Chrome会话和Chrome和Opera的登录问题 [英] Have to login twice. PHP sessions and login troubles with Chrome and Opera

问题描述

我遇到的问题是，我的登录表单需要登录两次才能正常注册，但仅限于Chrome（我的版本是4.0.249.89）和Opera（我的版本是10.10）。

以下是我正在测试的简化代码：

登录页面：

session_start（）;

  
 $ _SESSION ['user_id'] = 8; 
 $ _SESSION ['user_name'] ='Jim'; 
 
 session_write_close（）; 
 header（'Location：http://www.my-domain-name.com/'）; 
 exit（）;  

主页：

  
 session_start（）; 
 
 
 
 if（isset（$ _ SESSION ['user_id']））
 {
 
 echo您已登录！; 
 
} 
 else 
 {
 
 echo您未登录！; 
 
} 

注销页面：

  
 session_start（）; 
 session_unset（）; 
 session_destroy（）; 
 header（'Location： http://www.my-domain-name.com/ '）; 
 exit（）; 

目前，在没有Cookie的情况下，到my-domain-name.com/login/它将重定向到主页并说你没有登录！但如果我再次去那里，它会说你已经登录！。任何想法？

感谢您的帮助。 尝试添加一个 sleep（2）; 在发出重定向头之前;它会告诉你它是否实际上是代码中的一个错误，或者会话数据是否被写入文件的速度不够快。

The problem I am encountering is that for my login form I have to login twice for the session to register properly, but only in Chrome (my version is 4.0.249.89) and Opera (my version is 10.10).

Here is the stripped down code that I am testing on:

Login Page:

session_start();

 
$_SESSION['user_id'] = 8;
$_SESSION['user_name'] = 'Jim';

session_write_close();
header('Location: http://www.my-domain-name.com/');
exit();

Home Page:

session_start();


if ( isset($_SESSION['user_id']) )
{

    echo "You are logged in!";

}
else
{

    echo "You are NOT logged in!";

}

Logout Page:

session_start();
session_unset();
session_destroy();
header('Location: http://www.my-domain-name.com/');
exit();

Currently, under a fresh load with no cookies, if I go to my-domain-name.com/login/ it will redirect to the home page and say "You are NOT logged in!" but if I go there again it will say "You are logged in!". Any ideas?

Thanks for your help.

解决方案

Try adding a sleep(2); before issuing the redirect header; that'll tell you whether it's actually a bug in your code somewhere, or if the session data just isn't being written to file fast enough.
