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2011-11-22 10:10:00 我来说两句 收藏 我要投稿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.ResponseHeadersSet-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.ResponseHeadersSet-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(;); re
