Answer 1

写IE插件（BHO），在DISPID_BEFORENAVIGATE2事件中捕获其参数。

Answer 2

这样写对吗？postData = "{\"sportid\":\"10\",\"br\":\"000\",\"lid\":\"ch\",\"dt\":\"1\",\"mod\":11,\"str\":\"1999\",\"ods\":32,\"lvstat\":2}";
byteArray = Encoding.UTF8.GetBytes(postData);oReq = (HttpWebRequest)WebRequest.Create("http://u1xj36md09yg9r87.us.xxxxx.com/ennet/ajaxpro/Soccer.DisplaySingles,App_Code.ashx");
oReq.Referer = "http://u1xj36md09yg9r87.us.xxxxx.com/ennet/html/DisplaySingles.aspx?sid=k4H3SxFp97Qgf8MTch&sportid=10&events=1999&mode=11&odst=
";
oReq.CookieContainer = Configuration.cc;
oReq.Method = "POST";
oReq.Timeout = 6000;
oReq.ContentType = "text/plain; charset=utf-8";
oReq.Credentials = Configuration.oCred;
oReq.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Mozilla/4.0(Compatible Mozilla/4.0(Compatible-EmbeddedWB 14.59 http://bsalsa.com/ EmbeddedWB- 14.59  from: http://bsalsa.com/ ; .NET CLR 2.0.50727)";
oReq.ContentLength = byteArray.Length;
newStream = oReq.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.Length);
newStream.Close();oResp = (HttpWebResponse)oReq.GetResponse();
receiveStream = oResp.GetResponseStream();
readStream = new StreamReader(receiveStream, Encoding.UTF8);
SourceCode = readStream.ReadToEnd();
