Question

我正在使用php来刮WWW。需要会话才能登录的Example.com。我已经使用php curl成功登录了。请检查此链接Keeping session alive with curl and php。现在在链接中显示如何使用相同的会话cookie发出第二个请求。

我的问题是当我刮

时

define("COOKIE_FILE", "cookie.txt");  
    // Login the user  
    $ch = curl_init('http://api.example.com/login/joe/smith');  
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);   
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);  
    curl_setopt($ch, CURLOPT_HEADER, true);  
    echo curl_exec ($ch);

    // Read the session saved in the cookie file  
    echo "<br/><br/>";  
    $file = fopen("cookie.txt", 'r');
    echo fread($file, 100000000);     
    echo "<br/><br/>";

    // Get the users details
    $ch = curl_init('http://api.example.com/user');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    echo curl_exec ($ch);

我的代码是

define("COOKIE_FILE", "cookie.txt");
    // Login the user
    $ch = curl_init('http://api.example.com/login/joe/smith');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    echo curl_exec ($ch);

    // Read the session saved in the cookie file
    echo "<br/><br/>";
    $file = fopen("cookie.txt", 'r');
    echo fread($file, 100000000);   
    echo "<br/><br/>";

    // Get the users details
    $ch = curl_init('http://api.example.com/user');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=abc&password=xyz&domain=123');
    echo curl_exec ($ch);

输出

当第二个请求是GET请求时，一切正常。在POST请求时，网站返回“您的会话已过期，请再次登录”。

如何解决这个问题？。我已经尝试了几种解决方案并在谷歌搜索，没有任何作用。最终决定发布在这里。提前谢谢。
