四六级批量查询系统（C#源码）

四六级批量查询系统（C#源码）

今天我经过多方努力终于做出了”四六级查询系统“了，目前可以查整个学校，对那些忘记准考证号码的人很有帮助，其实具体的说他可以批量查询很大范围的成绩，昨晚虽然没有研究出来，但是今天99宿舍网站更改了验证方法，就算昨晚研究出结果今天也没用了。

---------------------------------

好了，好了，我的废话也说完了，现在开始进入正题，下面是一些关键的代码

昨天提交的代码是id=准考证号码&vc=novcversion今天要提交的是id=准考证&sid=cookie&vc=验证码，所以要有3方面的代码一个是判断验证码的，一个是活的COOKIE的，最后当然需要POST的代码啦！

判断验证码的也就是最难的，下面是判断验证码获取和COOKIE....关键代码如下

判断验证码和获取COOKIE

1 privatestring getcode()
2 {
3 UnCodebase codebase =new UnCodebase(this.CodeDisCern());
4 string str ="";
5 codebase.GrayByPixels();
6 codebase.ClearPicBorder(1);
7 codebase.CleanNoise(0xce, 0xce, 0xce);
8 codebase.CleanStand(0xff, 0xff, 0xff);
9 Bitmap[] splitPics = codebase.GetSplitPics();
10 for (int i =0; i <4; i++)
11 {
12 string singleBmpCode = codebase.GetSingleBmpCode(splitPics[i], 0x80);
13 for (int j =0; j <10; j++)
14 {
15 if (this.getSemblanceBy2words(singleBmpCode, this.num[j]) >0.9)
16 {
17 str = str + j.ToString();
18 break;
19 }
20 }
21 }
22 return str;
23 }
24
25
26
27 publicfloat getSemblanceBy2words(string word1, string word2)
28 {
29 float length = word1.Length;
30 float num2 = 0f;
31 for (int i =0; i < length; i++)
32 {
33 if (word1[i] != word2[i])
34 {
35 num2++;
36 }
37 }
38 return ((length - num2) / length);
39 }
40
41 private Bitmap CodeDisCern()
42 {
43 //验证码
44 Bitmap img =new Bitmap(0x40, 25);
45 //创建http请求
46 HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://cet.99sushe.com/validatecode");
47 req.Method ="GET";
48 req.Timeout =10000;
49 //保存cookie
50 CookieContainer cc =new CookieContainer();
51 req.CookieContainer = cc;
52 try
53 {
54 //获取返回信息
55 HttpWebResponse res = (HttpWebResponse)req.GetResponse();
56 //验证码图片
57 Stream resStream = res.GetResponseStream();
58 res.Cookies = cc.GetCookies(req.RequestUri);
59 cooc = cc.GetCookies(req.RequestUri);
60 //显示获取到的验证码图片
61 img =new Bitmap(resStream);
62 return img;
63 }
64 catch (Exception ex)
65 {
66 //MessageBox.Show(ex.ToString());
67 return img;
68
69 }
70 }

下面是POST的方法，也是最重要的

POST方法

1 string result ="";
2 HttpWebResponse res =null;
3 string str2 =this.getcode();
4
5 string paramList ="id="+ id +"&sid="+this.cooc[0].Value.ToString() +"&vc="+ str2;
6
7 byte[] data = Encoding.ASCII.GetBytes(paramList);
8 HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://cet.99sushe.com/getscore.html");
9 req.Method ="POST";
10 req.ContentType ="application/x-www-form-urlencoded;charset=gb2312";
11 req.Referer ="http://cet.99sushe.com";
12 req.ContentLength = data.Length;
13 Stream newStream = req.GetRequestStream();
14 newStream.Write(data, 0, data.Length);
15 newStream.Close();
16 res = (HttpWebResponse)req.GetResponse();
17 Stream s = res.GetResponseStream();
18 StreamReader sr =new StreamReader(s, Encoding.GetEncoding("GB2312"));
19 result = sr.ReadToEnd();
20

按照上面两个代码，基本上来个循环就能查整个学校的成绩了，下面是循环（写的不是很好）

循环方法

1 for (int i = start; i <= end; i++)
2 for (int n =1; n <31; n++)
3 {
4 if (i <10)
5 {
6 kc ="00"+ i.ToString();
7 }
8 if (i <100&& i >=10)
9 {
10 kc ="0"+ i.ToString();
11 }
12 if (n <10)
13 {
14 zh ="0"+ n.ToString();
15 }
16 else
17 {
18 zh = n.ToString();
19 }
20
21 richTextBox1.Text = richTextBox1.Text +"3510300921"+ kc + zh +"\n"+ query("3510300921"+ kc + zh) +"\n";
22 }

好了，基本介绍完毕了，总的来说我还是很惭愧的，没有真正自己研究出来......这里再次向shilin8805表示感谢！、
