C# 后台服务器端 Get 请求函数封装

1. 请求参数封装

   /// <summary>
   /// 拼接 Get请求参数
   /// </summary>
   /// <param name="parames"></param>
   /// <returns></returns>
   private static Tuple<string, string> GetQueryString(Dictionary<string, string> parames)
   {
       StringBuilder query = new StringBuilder("");
       StringBuilder queryStr = new StringBuilder("");
       if (parames == null || parames.Count == 0)
           return new Tuple<string, string>("", "");
   
       foreach (var item in parames)
       {
           string key = item.Key;
           string value = item.Value;
           if (!string.IsNullOrEmpty(key))
           {
               query.Append(key).Append(value);
               queryStr.Append("&").Append(key).Append("=").Append(value);
           }
       }
   
       return new Tuple<string, string>(query.ToString(), queryStr.ToString().Substring(1, queryStr.Length - 1));
   }

2. 请求方式函数封装

   /// <summary>
   /// 请求连接 函数封装
   /// </summary>
   /// <param name="requestType">请求方式：Get、Post等</param>
   /// <param name="requestLink">连接地址</param>
   /// <param name="query">请求参数</param>
   /// <returns></returns>
   public static string GetWeChatToken(string requestType,string requestLink, string query)
   {
       HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestLink + "?" + query);
       request.Method = requestType;
       request.ContentType = "application/json";
       request.Timeout = 90000;
       request.Headers.Set("Pragma", "no-cache");
       HttpWebResponse response = (HttpWebResponse)request.GetResponse();
       Stream streamReceive = response.GetResponseStream();
       StreamReader streamReader = new StreamReader(streamReceive, Encoding.UTF8);
       result = streamReader.ReadToEnd();
   
       streamReader.Close();
       streamReceive.Close();
       request.Abort();
       response.Close();
   
       return result;
   }
