上篇文章ASP.Net随想_了解下原始的东西HTTP简单的分析了aspx页面请求提交的HTTP数据包，并且说到我会写个自动注册机或者发帖的工具的，呵呵，工作忙得一笔，实在是抽不出身！今天休息，就接着上篇写下去吧！
上次我们监控到的HTTP数据包有两个属性很重要：

POST ：后面的东西，就是说这个请求处理的页面（URL）

Cokie：保持HTTP请求连续的标志，

还有一个也很重要：Referer，因为好多网站判断这个标志是否来自什么地方请求防止恶意注册，呵呵，知道该怎么做了吗？模拟你的请求吧！准备写个自动注册的东西，开始工作。寻找目标http://foxconnbbs.com/index.asp，呵呵，富士康的，我喜欢！随便找个帖子：http://foxconnbbs.com/dispbbs.asp?boardID=3&ID=3749&page=1注意URL参数的写法，这个和你自动生成所有的回帖有关，我就不在写这个Demo！只是真对这个帖子用Dot.Net实现外部提交！打开ieHTTPHeaders，分析下提交的数据格式:

呵呵，直到处理提交的URL: savepost.asp?action=sre&method=fastreply&BoardID=3，呵呵，别忘记前面加http://foxconnbbs.com/。为什么？晕到！Cookie也知道了吧！呵呵，提交的数据就是这一部分了。结下来就是如何模拟这个请求了，要想模拟这个请求，必须得出cookie的值，呵呵，如何得到这个Cookie哪？还得模拟登陆获得！看下登陆界面：

点击登录后注意提交数据，
呵呵，自己分析吧！

Ok!开始干活，自动登录获得Cookie的方法如下：

public string ShamLogin(string url, string usr,string pwd)

{

string Return = null;

this.LoginUrl = url;

string loginstr = "username="+usr+"&password="+pwd+"&CookieDate=0&submit=%B5%C7%C2%BC";

loginstr = EncodePost(loginstr);

byte[] replybyte = Encoding.UTF8.GetBytes(loginstr);

try

{

CookieContainer testCC = new CookieContainer();

TestRequest = (HttpWebRequest)WebRequest.Create(url);

TestRequest.CookieContainer = testCC;

TestRequest.ContentType = "application/x-www-form-urlencoded";

TestRequest.Method = "POST";

TestRequest.ContentLength = replybyte.Length;

Stream newStream = TestRequest.GetRequestStream();

newStream.Write(replybyte, 0, replybyte.Length);

newStream.Close();

TestResponse = (HttpWebResponse)TestRequest.GetResponse();

Stream dataStream = TestResponse.GetResponseStream();

StreamReader reader = new StreamReader(dataStream, Encoding.GetEncoding("gb2312"));

Return = reader.ReadToEnd();

// check cookie

foreach (Cookie temp in TestResponse.Cookies)

{

if (temp.Domain != "foxconnbbs.com")

temp.Domain = "foxconnbbs.com";

}

CkCollection = TestResponse.Cookies;

}

catch

{

return null;

}

return Return;

}

回复的代码如下：

public string Reply(string url,string formhash,string title,string content)

{

//post.php?action=reply&fid=84&tid=45444&extra=page%3D1&replysubmit=yes HTTP/1.1

//formhash=dcf4e770&subject=%B6%F1%C6%F8&message=eqw

TestRequest = (HttpWebRequest)WebRequest.Create("http://foxconnbbs.com/savepost.asp?action=sre&method=fastreply&BoardID=3");

TestRequest.ContentType = "application/x-www-form-urlencoded";

TestRequest.Method = "POST";

TestRequest.Referer = "http://foxconnbbs.com/dispbbs.asp?boardid=3&id=3711&star=1";

TestRequest.KeepAlive = true;

TestRequest.AllowWriteStreamBuffering = false;

// set cookie

CookieContainer cookieCon = new CookieContainer();

TestRequest.CookieContainer = cookieCon;

TestRequest.CookieContainer.Add(CkCollection);

// get post value

//formhash=dcf4e770&subject=%B6%F1%C6%F8&message=eqw

string reply = EncodePost("Body=%A3%BF%A3%BF%A3%BF&followup=18085&RootID=3711&star=1&TotalUseTable=dv_bbs1&UserName=roping&Expression=face1.gif&signflag=1&Submit=OK%21%B7%A2%B1%ED%BB%D8%B8%B4");

byte[] replybyte = Encoding.UTF8.GetBytes(reply);

TestRequest.ContentLength = replybyte.Length;

Stream newStream = TestRequest.GetRequestStream();

newStream.Write(replybyte, 0, replybyte.Length);

newStream.Close();

// get response

TestResponse = (HttpWebResponse)TestRequest.GetResponse();

Stream dataStream = TestResponse.GetResponseStream();

StreamReader reader = new StreamReader(dataStream, Encoding.GetEncoding("gb2312"));

string tt = reader.ReadToEnd();

reader.Close();

dataStream.Close();

TestResponse.Close();

return tt;

}
