我们在一些场合经常需要模拟浏览器进行一些操作，比如模拟投票，或者模拟点击，或者Web游戏外挂。而C#中封装好的WebClient可以在某些要求不算搞的场景实现Http的Post和Get。具体请见代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
namespace TestCNM
{
public class WebClientExt
{
public string Get(string Url,string Referer, Encoding Encoder,ref string CookieStr)
{
string result = "";
WebClient myClient = new WebClient();
myClient.Headers.Add("Accept: */*");
myClient.Headers.Add("User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET4.0E; .NET4.0C; InfoPath.2; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; SE 2.X MetaSr 1.0)");
myClient.Headers.Add("Accept-Language: zh-cn");
myClient.Headers.Add("Content-Type: multipart/form-data");
myClient.Headers.Add("Accept-Encoding: gzip, deflate");
myClient.Headers.Add("Cache-Control: no-cache");
if (CookieStr != "")
{
myClient.Headers.Add(CookieStr);
}
myClient.Encoding = Encoder;
result = myClient.DownloadString(Url);
if (CookieStr == "")
{
CookieStr = myClient.ResponseHeaders["Set-Cookie"].ToString();
CookieStr = GetCookie(CookieStr);
}
return result;
}
public string Post(string Url, string Referer, Encoding Encoder, ref string CookieStr, string Data)
{
string result = "";
WebClient myClient = new WebClient();
myClient.Headers.Add("Accept: */*");
myClient.Headers.Add("User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; Trident/4.0; .NET4.0E; .NET4.0C; InfoPath.2; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; SE 2.X MetaSr 1.0)");
myClient.Headers.Add("Accept-Language: zh-cn");
myClient.Headers.Add("Content-Type: multipart/form-data");
myClient.Headers.Add("Accept-Encoding: gzip, deflate");
myClient.Headers.Add("Cache-Control: no-cache");
if (CookieStr != "")
{
myClient.Headers.Add(CookieStr);
}
myClient.Encoding = Encoder;
result = myClient.UploadString(Url, Data);
if (CookieStr == "")
{
CookieStr = myClient.ResponseHeaders["Set-Cookie"].ToString();
CookieStr = GetCookie(CookieStr);
}
return result;
}
private string GetCookie(string CookieStr)
{
string result = "";
string[] myArray = CookieStr.Split(‘,‘);
if (myArray.Count() > 0)
{
result = "Cookie: ";
foreach (var str in myArray)
{
string[] CookieArray = str.Split(‘;‘);
result += CookieArray[0].Trim();
result += "; ";
}
result = result.Substring(0, result.Length - 2);
}
return result;
}
}
}
利用WebClient实现对Http协议的Post和Get对网站进行模拟登陆和浏览
