服务端代码

 [HttpPost]

        public ActionResult GetWeather()

        {

            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://api.map.baidu.com/telematics/v3/weather?location=厦门&output=json&ak=5slgyqGDENN7Sy7pw29IUvrZ");

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            Stream Strstream = response.GetResponseStream();

            StreamReader sr = new StreamReader(Strstream);

            return Content(sr.ReadToEnd());

        }
