.net - 如何让 HttpWebRequest 与 Netduino 一起工作？它给了我 System.NotSupportedException

Question

我正在尝试从我的 netduino 发送一个 http POST 请求，我一直在 netduino 论坛上，并且有相互冲突的报告说它能够工作，异常发生在第一行

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("example.com:8080");

            string postData = "temperature=" + tempSensor.Temperature;
            byte[] data = Encoding.UTF8.GetBytes(postData);

            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;

            using (Stream stream = request.GetRequestStream())
            {
                for (int i = 0; i < 10; i++)
                {
                    stream.Write(data, 0, data.Length);
                    Thread.Sleep(1000);
                }
            }

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Debug.Print(response.StatusDescription);

在您对.Create(...)方法的调用中，传递一个实例Uri或包含协议，即http://example.com:8080.
