ASP.Net 后台Post 请求

此方法不是本人原创，记载于此方便日后查看，以及有需要的童鞋参考

 

调用：

 string strKey = "12345678";

            string content = SecurityHelper.EncodeBase64(strKey);

            string message = Utils.RequestorHelper.PostWebRequest("Url", "title=公告测试&content=" + content + "&verify=be10c510b5f4f082dbd4268820cde895", new UTF8Encoding());

 

 

 public static string PostWebRequest(string postUrl, string paramData, Encoding dataEncode)
        {
            string ret = string.Empty;
            try
            {
                byte[] byteArray = dataEncode.GetBytes(paramData); //转化
                HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(postUrl));
                webReq.Method = "POST";
                webReq.ContentType = "application/x-www-form-urlencoded";

                webReq.ContentLength = byteArray.Length;
                Stream newStream = webReq.GetRequestStream();
                newStream.Write(byteArray, 0, byteArray.Length);//写入参数
                newStream.Close();
                HttpWebResponse response = (HttpWebResponse)webReq.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), dataEncode);
                ret = sr.ReadToEnd();
                sr.Close();
                response.Close();
                newStream.Close();
            }
            catch (Exception ex)
            {
                //Response.Write(ex.Message);
            }
            return ret;
        }

 

 

另一种方式：

public static string SendHttpPost( string url, NameValueCollection data)
        {
            System.Net.WebClient wc = new System.Net.WebClient();
            wc.Headers.Add("Accept-Language", "zh-cn");
            wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
            byte[] bytReturn = wc.UploadValues(url, "post", data);
            wc.Dispose();
            return System.Text.Encoding.GetEncoding("gbk").GetString(bytReturn);
        }
