後端 Post/Get 請求獲取介面資料

程式碼如下（示例）：（其中 我用到的是 ，Post請求是傳遞了兩個引數，Get請求是傳遞的Json型別資料）

   		// Get請求
        [WebMethod(Description ="獲取裝置")]
        public string testGet(string token)
        {
   
            Dictionary<string, string> dic = new Dictionary<string,
 
 string>();

            dic.Add("name",  "張三");
            dic.Add("age", "133");
            string result = "";
            StringBuilder builder = new StringBuilder();
            builder.Append("URL地址");
            if (dic.Count >
 
 0)
            {
                builder.Append("?");
                int i = 0;
                foreach (var item in dic)
                {
                    if (i > 0)
                        builder.Append("&");
                    builder.AppendFormat("{0}={1}"
 
, item.Key, item.Value);
                    i++;
                }
            }
            HttpWebRequest req = (HttpWebRequest)WebRequest.Create(builder.ToString());
            //新增引數
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
            Stream stream = resp.GetResponseStream();
            try
            {
                //獲取內容
                using (StreamReader reader = new StreamReader(stream))
                {
                    result = reader.ReadToEnd();
                }
            }
            finally
            {
                stream.Close();
            }
            return result;
        }


        // Post請求 引數json型別
        [WebMethod(Description ="token")]
        public string testpost()
        {
          
            string _url = "URL地址";
            //json引數
            string jsonParam = "{name:\'張三\',age:\'15\'}";
            var request = (HttpWebRequest)WebRequest.Create(_url);
            request.Method = "POST";
            request.ContentType = "application/json;charset=UTF-8";
            byte[] byteData = Encoding.UTF8.GetBytes(jsonParam);
            int length = byteData.Length;
            request.ContentLength = length;
            Stream writer = request.GetRequestStream();
            writer.Write(byteData, 0, length);
            writer.Close();
            var response = (HttpWebResponse)request.GetResponse();
            var responseString = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding("utf-8")).ReadToEnd();
           return responseString.ToString();

        }
