[英]HttpWebRequest Fails Compact Framework
尝试在Windows Mobile 6.5设备上发出Http POST请求
我可以在设备上的浏览器中查看网页,但是Http请求失败
private string SendData(string directory, string data)
{
string page = string.Format("http://{0}/{1}", hostname, directory);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(page);
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.Method = "POST";
request.ContentType = "text/json";
byte[] postBytes;
if (data != null)
{
postBytes = Encoding.UTF8.GetBytes(data);
}
else
{
postBytes = new byte[0];
}
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postBytes.Length;
/*
Stream requestStream = request.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
*/
HttpWebResponse response = null;
try
{
response = (HttpWebResponse)request.GetResponse();
if (response.StatusCode == HttpStatusCode.OK)
Console.WriteLine("\r\nResponse Status Code is OK and StatusDescription is: {0}",
response.StatusDescription);
}
catch (WebException e) {
Debug.WriteLine("\r\nWebException Raised. The following error occured : "+e.Status);
}
}
我已经注释掉了POST Stream,直到我得到一个简单的请求为止
如果没有try catch
我会收到“无法连接到远程服务器”的提示并崩溃。
原来这段代码很好
通过USB插入计算机后,设备将失去连接。
关闭Windows Mobile设备中心后,它工作正常。
