下面我就把我的代码贴出来。为了安全,我隐藏了所有相关的真实网址。
下面首先是命名空间的引用:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;//访问数据流,网页回传的都先是数据流
using System.Text;
using System.Text.RegularExpressions;//正则表达式用来验证回传的网页是否包含目标数据
using System.Windows.Forms;
using System.Net;//必须,对网页的访问通过这个命名空间来实现的
接着是一个函数来实现,为了安全,隐藏了敏感数据(使用星号)
public Boolean VoteOnce()
{
//创建HttpWebRequest发送请求用
HttpWebRequest hwrq = (HttpWebRequest)WebRequest.Create("http://www.***.com/***/***.asp?***=***&***=***");
//下面是相关数据头和数据发送方法
hwrq.Accept = "application/x-shockwave-flash, image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";
hwrq.Referer = "http://www.***.com/***/***.asp?***=***&***=***";
hwrq.ContentType = "application/x-www-form-urlencoded";
hwrq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; MAXTHON 2.0)";
hwrq.KeepAlive = true;
hwrq.Method = "POST";
//下面发送数据,使用MiniSniffer来抓包分析应该发送什么数据
string PostStr = "*=****%**&****=*";
ASCIIEncoding ASC2E = new ASCIIEncoding();
byte[] bytePost = ASC2E.GetBytes(PostStr);//把要发送的数据变成字节
hwrq.ContentLength = bytePost.Length;
//下面是发送数据的字节流
Stream MyStream = hwrq.GetRequestStream();
MyStream.Write(bytePost, 0, bytePost.Length);
MyStream.Close();//记得要结束字节流啊
//创建HttpWebResponse实例
HttpWebResponse hwrp = (HttpWebResponse)hwrq.GetResponse();
StreamReader MyStreamR = new StreamReader(hwrp.GetResponseStream(), Encoding.Default);
string result = MyStreamR.ReadToEnd();
Boolean r=false;
if (Regex.IsMatch(result, "成功")==true)
{
r = true;
}
MyStreamR.Close();
return r;
