c#無(wú)法發(fā)送具有此謂詞類(lèi)型的內(nèi)容正文 異常

今天用到之前封裝的web request 請(qǐng)求，但拋錯(cuò)：無(wú)法發(fā)送具有此謂詞類(lèi)型的內(nèi)容正文。

經(jīng)過(guò)檢查，發(fā)現(xiàn)之前的方法里面有GetRequestStream(), GET請(qǐng)求并不支持，于是把GetRequestStream()和相應(yīng)的代碼注釋掉就OK了

下面提供完整的c# web request 請(qǐng)求方法供參考

        /// <summary>
        /// 請(qǐng)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(jié)果</param>
        /// <param name="_ErrMsg">錯(cuò)誤時(shí)的錯(cuò)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;
        }
