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
view plaincopy to clipboardprint?//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;
}

//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; }
