后台Post/Get 请求接口 方式

Post请求

 public string HttpPost(string Url, string postDataStr)
    {
        try
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url);
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";//请求方约定好

            byte[] bs = Encoding.UTF8.GetBytes(postDataStr);
            request.ContentLength = bs.Length;
            using (Stream reqStream = request.GetRequestStream())
            {
                reqStream.Write(bs, 0, bs.Length);
            }

            HttpWebResponse response;
            response = (HttpWebResponse)request.GetResponse();      
           
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));//一般参数带中文 用utf-8
            string retString = myStreamReader.ReadToEnd();
            myStreamReader.Close();
            myResponseStream.Close();

            return retString;
        }
        catch (Exception ex)
        {
            LogHelper.WriteLog(ex.Message, "");
        }
        return null;
    }

Get 请求

  public static string Get_Http(string strUrl, int timeout)
    {
        string strResult;
        try
        {
            HttpWebRequest myReq = (HttpWebRequest)HttpWebRequest.Create(strUrl);
            myReq.Timeout = timeout;
            HttpWebResponse HttpWResp = (HttpWebResponse)myReq.GetResponse();
            Stream myStream = HttpWResp.GetResponseStream();
            StreamReader sr = new StreamReader(myStream, Encoding.UTF8);
            StringBuilder strBuilder = new StringBuilder();
            while (-1 != sr.Peek())
            {
                strBuilder.Append(sr.ReadLine());
            }

            strResult = strBuilder.ToString();
        }
        catch (Exception exp)
        {
            strResult = "错误：" + exp.Message;
        }

        return strResult;
    }
