cURL不起作用

Question

那么，我想在某些页面上使用cURL登录。 当我在浏览器中将该数据粘贴到该地址栏中时 http://mywebpage.net/login.php?username=HERESMYUSERNAME&password=dded0102f44e7e0809520eb93055cb16 页面将我带到地址http://mywebpage.net/user.php，一切正常。 现在我想通过使用cURL来获得相同的效果，但是不起作用。

$url="http://mywebpage.net/login.php"; 
$cookie="cookie.txt"; 

$postdata = "username=cow&password=ass"; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 0); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

if (!$result) { 
     $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
     curl_close($ch); // make sure we closeany current curl sessions 
     die($http_code.' Unable to connect to server. Please come back later.'); 
    } 
echo $result; 
curl_close($ch); 

它向我显示空白输入的登录页面，它不会登录我并移动到正确的地址。 当我键入www.mywebpage.net/user.php显示 “错误401”

在这里工作代码：

$url="http://mywebpage.net/login.php?username=user&password=ddad0102f44e7f0800354eb11155cb16"; 
$cookie="cookie.txt"; 

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6"); 
curl_setopt ($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_COOKIEJAR, $cookie); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 

curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 

if (!$result) { 
     $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
     curl_close($ch); // make sure we closeany current curl sessions 
     die($http_code.' Unable to connect to server. Please come back later.'); 
    } 
echo $result; 
curl_close($ch); 

如何我现在可以重定向自己/all.php？

Answer 1

我看到三件事情错

1. 您正在使用curl POST而不是GET
2. CURLOPT_FOLLOWLOCATION设置为false，但您的登录脚本并重定向到user.php的，即使验证工作，你会得到空的回应。我认为你应该设置CURLOPT_FOLLOWLOCATION为真
3. 你给的网址无效或不工作..我不确定这是真实的URL还是只是一个例子。
