關於C# 使用HttpContent調用接口

1.c# 關於Content與ContentType之前的對應關系：

   MultipartFormDataContent=》multipart/form-data

   FormUrlEncodedContent=》application/x-www-form-urlencoded

   StringContent=》application/json等

   StreamContent=》binary

2.c#中request和response的編碼和請求類型設置

                // dict為Dictionary<string, string>，from類型數據

                HttpContent httpContent = new FormUrlEncodedContent(dict);

 httpContent.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded"); httpContent.Headers.ContentType.CharSet = "GBK"; var response = _HttpClient.PostAsync(url, httpContent).Result; response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json"); response.Content.Headers.ContentType.CharSet = "GBK";
                // 接口返回數據
                responseJson = response.Content.ReadAsStringAsync().Result;
