在 WP7 中發送圖像

Question

我需要使用參數“access_token”和“photo”（我需要發送的圖像）將圖像（jpeg、png 等）發送到服務器。

..if (e.TaskResult == TaskResult.OK) {
                BitmapImage image = new BitmapImage();
                image.SetSource(e.ChosenPhoto);
                //  foto.Source = image;
                Byte[] byteArray;
                using (MemoryStream ms = new MemoryStream()) {
                    WriteableBitmap btmMap = new WriteableBitmap(image);

                    // write an image into the stream
                    System.Windows.Media.Imaging.Extensions.SaveJpeg(btmMap, ms, image.PixelWidth, image.PixelHeight, 0, 100);

                    byteArray = ms.ToArray();
                }
((App)Application.Current).get_data(uploadServer + "?photo=" + *HOW I CAN SEND BYTE ARRAY?* + "&access_token=" + ((App)Application.Current).access_token

//

public void get_data(string url,Action<string> qw) {
            try {
                var request = (HttpWebRequest)WebRequest.Create(
                    new Uri(url));
                request.BeginGetResponse(r => {
                    var httpRequest = (HttpWebRequest)r.AsyncState;
                    var httpResponse = (HttpWebResponse)httpRequest.EndGetResponse(r);
                    HttpStatusCode st = httpResponse.StatusCode;
                    if (st == HttpStatusCode.NotFound) {
                        ToastPrompt toast = new ToastPrompt();
                        toast.TextOrientation = System.Windows.Controls.Orientation.Vertical;
                        toast.Message = "Ошибка соединения с сервером";
                        toast.MillisecondsUntilHidden = 2000;
                        toast.Show();
                    } else
                        using (var reader = new StreamReader(httpResponse.GetResponseStream())) {
                            var response = reader.ReadToEnd();
                            Deployment.Current.Dispatcher.BeginInvoke(new Action(() => {
                                qw(response);
                            }));

                        }
                }, request);
            } catch (WebException e) { }
        }

Answer 1

您不能將圖像“獲取”到 URL（您試圖將數據發布到 URL 中，但您不能），您需要使用 POST 請求的OutputStream來“發布”您的圖像。

Answer 2

WP7 - 帶有圖像的 POST 表單

Dictionary<string, object> data = new Dictionary<string, object>()
                    {
                    {"photo", byteArray},
                    };
                    PostSubmitter post = new PostSubmitter() { url = uploadServer, parameters = data };
                    post.Submit();
