这里我的帖子请求代码：

Here my post request code:

var queryString = HttpUtility.ParseQueryString(string.Empty);
                        queryString["visualFeatures"] = "Categories,Adult,Faces";
                        queryString["subscription-key"] = "<MY_SUBSCRIPTION_KEY>";
                        var uri = new Uri("https://api.projectoxford.ai/vision/v1/analyses?" + queryString);
                        request = (HttpWebRequest)WebRequest.Create(uri);
                        request.Method = "POST";
                        request.ContentType = "application/octet-stream";
                        request.ContentLength = img.Length;
                        var responseString = "";
                        using (var stream = request.GetRequestStream())
                        {
                            stream.Write(img, 0, img.Length);
                        }
                        var response = (HttpWebResponse)request.GetResponse();
                        responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
