POST发送:
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(new Uri(PostInitUrl));
httpWebRequest.ContentType = "application/json; charset=utf-8";
httpWebRequest.Method = "POST";
httpWebRequest.BeginGetRequestStream((IAsyncResult streamCallback) =>
{
try
{
HttpWebRequest webRequest = streamCallback.AsyncState as HttpWebRequest;
byte[] buffer = Encoding.UTF8.GetBytes(Serializer<UserDevice>(ud));
Stream stream = webRequest.EndGetRequestStream(streamCallback);
stream.Position = 0;
stream.Write(buffer, 0, buffer.Length);
stream.Close();
webRequest.BeginGetResponse((IAsyncResult responseCallback) =>
{
try
{
HttpWebRequest webRequest2 = responseCallback.AsyncState as HttpWebRequest;
HttpWebResponse webResponse = (HttpWebResponse)webRequest2.EndGetResponse(responseCallback);
Stream streamResponse = webResponse.GetResponseStream();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Result));
Result cr = ser.ReadObject(streamResponse) as Result;
if (cr.code == 1)
{
action(true, null);
}
else
{
action(false, new Exception(cr.msg));
}
}
catch (Exception e2)
{
action(false, e2);
}
}, webRequest);
}
catch (Exception e1)
{
action(false, e1);
}
}, httpWebRequest);
其中序列化的方法：
private static string Serializer<T>(T t)
{
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
MemoryStream ms = new MemoryStream();
ser.WriteObject(ms, t);
byte[] array = ms.ToArray();
string jsonString = Encoding.UTF8.GetString(array, 0, array.Length);
ms.Close();
return jsonString;
}
服务端接收数据并返回结果：
public Result Post([FromBody]UserDevice userDevice)
{
if (userDevice != null && userDevice.deviceUniqueId != null)
{
return new Result(1, "OK");
}
else
{
return new Result(0, "参数错误");
}
}
