“我要上春晚”刷票器

 ccav的“我要上春晚”设置了投票功能，选人气王。写了一个简单的刷票器。

先下班了。代码有空再写。

接昨天的。

比如这个投票页面：http://cctv.cntv.cn/woyaoshangchunwan/vote/02/index.shtml

先随便投一下，抓包。post的数据包如：

encoding=gb2312&_charset_=UTF-8&retUrl=http%3A%2F%2Fapp1.vote.cntv.cn%2FviewResult.jsp%3FvoteId%3D3434&formhash=69256b23&voteId=3434&type=html&items_6351=36451&63=%E7%8E%8B%E5%B0%8F%E4%BA%8C&65=身份证号&submitBtn=%E6%8A%95%E7%A5%A8

提交后的处理页面为 http://app2.vote.cntv.cn/makeVoteAction.do

一共提交了节目ID、编码后的姓名、身份证号几项信息。然后用HttpWebRequest模拟发送数据即可。

身份证号可以随机生成，我是从一个excel表里读取的。

主要代码如下：

/// <summary> /// Handles the Click event of the btnVote control. /// </summary> /// <param name="sender">The source of the event.</param> /// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param> private void btnVote_Click(object sender, EventArgs e) { try { int interval = Convert.ToInt32(this.txtInterval.Text.Trim()); //读取excel表格中的数据 string FilePath = this.txtFileName.Text.Trim(); OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + FilePath + ";Extended Properties = Excel 8.0"); conn.Open(); string strSQL = "select * from [职工表$] "; OleDbCommand cmd = new OleDbCommand(strSQL, conn); OleDbDataReader odr = cmd.ExecuteReader(); int i = 0; while (odr.Read()) { //创建HttpWebRequest HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(this.txtAction.Text); string postData = @"encoding=gb2312&_charset_=utf-8&retUrl=http%3A%2F%2Fapp1.vote.cntv.cn%2FviewResult.jsp%3FvoteId%3D3422&formhash=69256b23&voteId=3422&type=html&场次ID=节目ID&10=" + Uri.EscapeDataString(odr["姓名"].ToString()) + "&11=" + odr["身份证号"].ToString() + "&submitBtn=%E6%8A%95%E7%A5%A8"; //在发送的内容里包括中文和空格 ASCIIEncoding encoding = new ASCIIEncoding(); byte[] byte1 = encoding.GetBytes(postData);//最终编码后要上传的数据 //Setthecontenttypeofthedatabeingposted. myHttpWebRequest.ContentType = "application/x-www-form-urlencoded"; myHttpWebRequest.Method = "post";//post上传方式 //Setthecontentlengthofthestringbeingposted. //myHttpWebRequest.Referer = @"http://cctv.cntv.cn/woyaoshangchunwan/vote/02/index.shtml"; myHttpWebRequest.ContentLength = byte1.Length; Stream newStream = myHttpWebRequest.GetRequestStream(); newStream.Write(byte1, 0, byte1.Length); //加上这句释放资源 否则执行两次就卡住了 myHttpWebRequest.Abort(); newStream.Close(); //Get the new response //HttpWebResponse response = myHttpWebRequest.GetResponse() as HttpWebResponse; //Stream responseStream = response.GetResponseStream(); //StreamReader reader = new System.IO.StreamReader(responseStream); //string srcString = reader.ReadToEnd(); //this.txtResponseInfo.Text = srcString; Thread.Sleep(interval); i++; } this.txtResponseInfo.Text = "已处理完。共投票" + i.ToString() + "次"; odr.Close(); cmd.Dispose(); conn.Close(); conn.Dispose(); } catch(Exception ex) { MessageBox.Show("错误信息：" + ex.Message); } }

注意发送数据如果有中文的话要Uri.EscapeDataString()一下，这样就基本可以运行了。继续完善的话，可以加上设置投票节目ID、增加线程处理等。

这个投票没有验证码，刷票的挺多的。
