如何在使用POST时上传大字符串(例如带有BLOB的XML)而不会因为GetResponse超时?
更改超时时间可以解决问题,但这并不是真正的解决方案。如果服务器真的挂了或者POST被中断,我需要等待极长的超时时间。
有什么好的想法吗?
HttpWebRequest webRequest = null;
string response = "";
byte[] bytes = Encoding.UTF8.GetBytes(xml);
try
{
webRequest = (HttpWebRequest)WebRequest.Create("http://" + this.host + ":" + this.port);
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
webRequest.Timeout = 5000;
webRequest.ContentLength = bytes.Length;
using (Stream requeststream = webRequest.GetRequestStream())
{
requeststream.Write(bytes, 0, bytes.Length);
requeststream.Close();
}
using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
{
using (StreamReader sr = new StreamReader(webResponse.GetResponseStream()))
{
response = sr.ReadToEnd().Trim();
sr.Close();
}
webResponse.Close();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
return response;
