卷发给出403错误？

Question

我正在尝试从MediaWiki登录页面为我的PHPBB论坛设置cookie。登录到Wiki后使用钩子成功，我想运行一个设置Cookie的PHP脚本。

当我独立运行或使用Get时，该脚本可以工作，但出于安全原因，我想将其发布到脚本上。为此我想 curl 将是最好的选择。

不幸的是，即使是这样的基本脚本：

curl_setopt($ch, CURLOPT_URL, "http://www.example.com/ForumLogin.php");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);

给我403禁止错误。 robots.txt中没有任何规则可以干扰。我还能尝试让脚本工作，还是我可以从MediaWiki中运行脚本的其他方法？

Answer 1

我怀疑这是明确的理由是停止自动化行为 - 一种反机器人或一般安全措施。您可能希望查看目标站点的源代码并检查任何此类措施 - 快速搜索“ 403”代码可能会提供一些见解。在这种情况下，帖子请求也不合法，因此出于安全原因而阻止。

我不确定您的意思是“出于安全原因”。帖子不比获得更安全。他们都接受了同样多的审查。

Answer 2

对于我的特定项目，如果发生错误，服务器将丢弃403错误，但仍会返回数据。因此，为解决这个问题，我做到了：

curl_setopt($ch, CURLOPT_FAILONERROR, 0); // Fail on errors

如果您禁用错误失败，则可能仍然会收回一些数据。希望有帮助。

我的解决方案是设置用户代理选项，以便卷曲可以假装为浏览器。在PHP中设置的一个示例是

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.2) AppleWebKit/536.6 (KHTML, like Gecko) Chrome/20.0.1090.0 Safari/536.6');

参考：

• http://www.useragentstring.com/pages/browserlist/

Answer 4

采取行动/请求，例如真实的尝试“ curl/7.39.0”用户代理

$useragent= "curl/7.39.0";
curl_setopt($ch,CURLOPT_USERAGENT, $useragent);

或尝试从浏览器阵列列表中尝试Randam用户代理

//browser pack start
         $useragents=array(
