模拟提交数据，获取结果

发现这个很好，缺点就是没有成功案例，测试成功发个案例上来，呵呵。

模拟Post/get提交数据 并抓取返回数据

最近需要做的项目中，使用httpwebrequest httpwebrespone来模拟提交数据

还有模拟用户登录后提交数据。

下面做个简单一点的。模拟post提交数据，get在前面的抓取sina的天气预报也使用到了。

下面是代码

//提交的post数据
stringpostData=string.Format("account={0}&reaccount={0}&cardcode={1}&cardpassword={2}",txtLoginId.Text,txtCardNo.Text,txtPass.Text);
postData+=string.Format("&__EVENTTARGET={0}&__EVENTARGUMENT=&__VIEWSTATE={1}","nextStep","YToxOntzOjExOiJjdXJyZW50VXNlciI7YjowO30=");
HttpWebResponseresponse;
HttpWebRequestrequest;
ASCIIEncodingencoding=newASCIIEncoding();
byte[]data=encoding.GetBytes(postData);
request=(HttpWebRequest)WebRequest.Create("url");
data=encoding.GetBytes(postData);
request.Method="POST";
request.ProtocolVersion=HttpVersion.Version10;
request.UserAgent="Mozilla/4.0";

request.ContentType="application/x-www-form-urlencoded";
request.ContentLength=data.Length;
Streamstream=request.GetRequestStream();
stream.Write(data,0,data.Length);
stream.Close();
stringhtml=string.Empty;
try
{
//获取服务器返回的资源
response=(HttpWebResponse)request.GetResponse();
StreamReaderreader=newStreamReader(response.GetResponseStream(),Encoding.Default);
html=reader.ReadToEnd();
reader.Close();
response.Close();
textBox1.Text=html;
}
catch(Exceptionex)
{
label4.Text=ex.Message;
}

//提交的post数据            string postData = string.Format("account={0}&reaccount={0}&cardcode={1}&cardpassword={2}",txtLoginId.Text,txtCardNo.Text,txtPass.Text);            postData += string.Format("&__EVENTTARGET={0}&__EVENTARGUMENT=&__VIEWSTATE={1}", "nextStep", "YToxOntzOjExOiJjdXJyZW50VXNlciI7YjowO30=");            HttpWebResponse response;            HttpWebRequest request;            ASCIIEncoding encoding = new ASCIIEncoding();            byte[] data = encoding.GetBytes(postData);            request = (HttpWebRequest)WebRequest.Create("url");            data = encoding.GetBytes(postData);            request.Method = "POST";            request.ProtocolVersion = HttpVersion.Version10;            request.UserAgent = "Mozilla/4.0";            request.ContentType = "application/x-www-form-urlencoded";            request.ContentLength = data.Length;            Stream stream = request.GetRequestStream();            stream.Write(data, 0, data.Length);            stream.Close();            string html = string.Empty;            try            {                //获取服务器返回的资源                response = (HttpWebResponse)request.GetResponse();                StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.Default);                html = reader.ReadToEnd();                reader.Close();                response.Close();                textBox1.Text = html;            }            catch (Exception ex)            {                label4.Text = ex.Message;            }
