中国网建的短信接口实现

实现相对简单,发送手机号和内容到特定url就行了,代码如下:

public string SendSMS(string mobile, string content)
        {
            string UserName = "账号";//网建账号
            string PassWord = "密码";//提供的密码
            string url = "http://utf8.sms.webchinese.cn";//路径
            string result = "";
            int re = 0;
            try
            {
                HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
                request.Method = "Post";
                request.ContentType = "application/x-www-form-urlencoded";
                StringBuilder buffer = new StringBuilder();
                buffer.AppendFormat("Uid={0}", UserName);
                buffer.AppendFormat("&Key={0}", PassWord);
                buffer.AppendFormat("&smsMob={0}", mobile);
                buffer.AppendFormat("&smsText={0}", HttpUtility.UrlEncode(content + "【内部管理系统】", Encoding.UTF8));
                byte[] data = Encoding.UTF8.GetBytes(buffer.ToString());
                using (Stream stream = request.GetRequestStream())
                {
                    stream.Write(data, 0, data.Length);
                }
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8);
                string msg = sr.ReadToEnd();
                sr.Close();
                int.TryParse(msg, out re);
                if(re<=0)
                {
                    result = "短信发送失败！错误代码：" + msg;
                }
                else
                {
                    result = "短信发送成功";
                }
            }
            catch (Exception ex)
            {
                result = "短信发送失败!错误信息:" + ex;
            }
            return result;
        }
