Http请求方法封装

• POST请求

    public static string HttpPost(string url, string data)
          {
              string address = url;
              HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
  
              request.Method = "POST";
              request.ContentType = "application/json";
              string strContent = data; //json字符串
              using (StreamWriter dataStream = new StreamWriter(request.GetRequestStream()))
              {
                  dataStream.Write(strContent);
                  dataStream.Close();
              }
              HttpWebResponse response = (HttpWebResponse)request.GetResponse();
              string encoding = response.ContentEncoding;
              if (encoding == null || encoding.Length < 1)
              {
                  encoding = "UTF-8"; //默认编码  
              }
              StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
              string retString = reader.ReadToEnd();
  
              //解析josn
              //JObject jo = JObject.Parse(retString);
              return retString;
          }
  
  

• GET请求

    //[WebMethod]
          public static string HttpGet(string url)
          {
              //预备请求的资源
              HttpWebRequest request = null;
              HttpWebResponse response = null;
              StreamReader reader = null;
  
              string content = string.Empty;
              //实例化一个http请求
              request = (HttpWebRequest)WebRequest.Create(url);
              //设置请求头 请求方式method=get
              request.Method = "GET";
              //使request。getResponse()返回的一个响应对象
              response = (HttpWebResponse)request.GetResponse();
              //reader 读取响应流
              using (reader = new StreamReader(response.GetResponseStream()))
              {
                  //意思是从头读到尾，全部读完
                  content = reader.ReadToEnd();
              }
  
              return content;
          }
