HTTP 响应错误 503
Httpresponse Error 503
我正在尝试从 CloudFlare 托管的网站下载网页数据。它使用 HTTPS 并在进入页面之前获取连接 ID。
我试图在 WebRequest 和 WebResponse 中获取 ID,但出现以下错误:
An unhandled exception of type 'System.Net.WebException' occurred in System.dll
Additional information: The remote server returned an error: (503) Server Unavailable.
我尝试从 Fiddler 发出请求,这是响应:
HTTP/1.1 503 Service Temporarily Unavailable

这是我的代码:
public static string GetCookie(string link)
{
WebRequest request = WebRequest.Create("https://hornystress.me");
request.Proxy = WebProxy.GetDefaultProxy();
request.Timeout *= 100;
WebResponse response = request.GetResponse();
return response.Headers.Get("Set-Cookie");
}
无论您在做什么,都可能看起来像是对网站的攻击,并且它正在触发安全功能。您可能希望网站所有者将发出呼叫的 IP 列入白名单。
这是 Cloudflare 安全性,旨在阻止您正在尝试做的事情。您将无法使用脚本访问该站点。
问题是网站的正常响应是 Error code 503
我想要的 cookie...所以编译器会抛出 WebException
错误;我应该抓住...
public static string GetCookie()
{
WebRequest request = WebRequest.Create("https://hornystress.me");
request.Proxy = WebProxy.GetDefaultProxy();
request.Timeout *= 100;
string cookie;
WebResponse response;
try
{
response = request.GetResponse();
cookie = response.Headers.Get("Set-Cookie");
}
catch (WebException we)
{
cookie=we.Response.Headers.Get("Set-Cookie");
}
return cookie;
}
