public static string Post(string url) { string result = ""; HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url); req.Method = "POST"; HttpWebResponse resp = (HttpWebResponse)req.GetResponse(); Stream stream = resp.GetResponseStream(); //获取内容 using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)) { result = reader.ReadToEnd(); } return result; }
