                    string tokenData = CreateToken(postDataJson, "123");
                    string parameters = "method=getRintoneCategories&data=" + postDataJson + "&token=" + tokenData;
                    string jsonData = JsonConvert.SerializeObject(parameters);
                    req.Content = new StringContent(parameters, Encoding.UTF8, "application/json");
    
                    client.SendAsync(req).ContinueWith(respTask =>
                    {
                        Debug.WriteLine("Response: {0}", respTask.Result);
                    });

推荐答案

client = new HttpClient();
                    client.DefaultRequestHeaders.Add("User-Agent", "RingtoneApplication");
                    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                    Object[] dataObj = CreateData();
                    string dataString = JsonConvert.SerializeObject(dataObj);
                    var values = new List<KeyValuePair<string, string>>();
                    values.Add(new KeyValuePair<string, string>("data", dataString));
                    values.Add(new KeyValuePair<string, string>("method", "getRintoneCategories"));
                    string token = CreateToken(dataString, "123");
                    values.Add(new KeyValuePair<string, string>("token", token));
                    var content = new FormUrlEncodedContent(values);
                    var response = await client.PostAsync("http://192.168.0.103/new_ringtone/", content);
                    responseString = await response.Content.ReadAsStringAsync();
