c#無法發送具(jù)有(yǒu)此謂詞類型的内容正文(wén) 異常

今天用(yòng)到之前封裝(zhuāng)的web request 請求，但抛錯：無法發送具(jù)有(yǒu)此謂詞類型的内容正文(wén)。

經過檢查，發現之前的方法裏面有(yǒu)GetRequestStream(), GET請求并不支持，于是把GetRequestStream()和相應的代碼注釋掉就OK了

下面提供完整的c# web request 請求方法供參考

        /// <summary>
        /// 請求url，并獲取返回值
        /// </summary>
        /// <param name="postUrl">url地址</param>
        /// <param name="_Encode">Encoding 編碼</param>
        /// <param name="_Result">返回結果</param>
        /// <param name="_ErrMsg">錯誤時的錯誤消息</param>
        /// <returns></returns>
        public bool WebRequestData(string postUrl, Encoding _Encode, ref string _Result, ref string _ErrMsg)
        {
            bool bln = false;
            try
            {
                HttpWebRequest webReq = (HttpWebRequest)WebRequest.Create(new Uri(postUrl));
                webReq.Method = "GET";
                webReq.ContentType = "application/x-www-form-urlencoded";

                HttpWebResponse response = (HttpWebResponse)webReq.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                _Result = sr.ReadToEnd();

                bln = true;

                sr.Close();
                response.Close();
            }
            catch (Exception ex)
            {
                _ErrMsg = ex.Message;
            }
            return bln;
        }
