Question

我正在尝试使用公共代理服务器（http://www.unblockwebnow.info/）向目标网站发送HTTP请求，比如http://stackoverflow.com：）

我的HTTP客户端具有以下架构：

string url = "http://stackoverflow.com";
HttpWebRequest HttpWRequest = (HttpWebRequest)WebRequest.Create(url);
HttpWRequest.Method = "GET";

WebProxy myProxy = new WebProxy();
myProxy.Address = new Uri("http://www.unblockwebnow.info/");
HttpWRequest.Proxy = myProxy;

HttpWebResponse HttpWResponse = (HttpWebResponse)HttpWRequest.GetResponse();
StreamReader sr = new StreamReader(HttpWResponse.GetResponseStream(), encoding);
var rawHTML = sr.ReadToEnd();
sr.Close();

执行rawHTML的代码后，我得到"pageok -managed by puppet - hostingcms02 pageok"

如果我评论HttpWRequest.Proxy = myProxy;行，我会收到网站内容。

这似乎有效，但不适用于您的代理（不知道unblockwebnow.info的端口号）。在URI

中的“：”之后添加了端口号

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "http://stackoverflow.com";
            HttpWebRequest HttpWRequest = (HttpWebRequest)WebRequest.Create(url);
            HttpWRequest.Method = "GET";

            WebProxy myProxy = new WebProxy();

            //United States proxy, from http://www.hidemyass.com/proxy-list/
            myProxy.Address = new Uri("http://72.64.146.136:8080");
            HttpWRequest.Proxy = myProxy;

            HttpWebResponse HttpWResponse = (HttpWebResponse)HttpWRequest.GetResponse();
            StreamReader sr = new StreamReader(HttpWResponse.GetResponseStream(), true);
            var rawHTML = sr.ReadToEnd();
            sr.Close();

            Console.Out.WriteLine(rawHTML);
            Console.ReadKey();
        }
    }
}

在HTTP客户端中使用公共代理服务器
