推荐答案

我可以确认下面的代码适用于Pi，10240或10586，如果有帮助的话

Well I can confirm that the below code works on the Pi, 10240 or 10586 if that helps

//using System.Net.Http;
using Windows.Web.Http;
...
...
            // Create a New HttpClient object and dispose of it when done.
            using (HttpClient httpClient = new HttpClient())
            {
                httpClient.DefaultRequestHeaders.Add("Cache-Control", "no-cache");

                // Call asynchronous network methods in a try/catch block to handle exceptions
                try
                {
                    //HttpStringContent stringContent = new HttpStringContent("test data");
                    //HttpStreamContent streamContent = new HttpStreamContent(new InMemoryRandomAccessStream());
                    //HttpBufferContent bufferContent = new HttpBufferContent(new Windows.Storage.Streams.Buffer(100));

                    Uri uri = new Uri("http://{myRESTserver}/{myRESTservice}?{parameters}");
                    HttpResponseMessage response = await httpClient.PostAsync(uri, null); 
                    // or add content (see above) as required in place of the null
                    response.EnsureSuccessStatusCode();
                    string responseBody = await response.Content.ReadAsStringAsync();
                    // TODO: Do something with the responseBody
                }
                catch (Exception ex)
                {
                    // TODO: Deal with exception - could be a server not found, 401, 404, etc.
                }
            }
