正则表达式之AAA云推荐码的获取

遗憾迟香

第一次练习C#的正则表达式AAA云推荐码的格式为:
AAAYUN{0}-{1}
{0}为13个字符,{1}为八位日期
正则表达式如下
AAAYUN.{13}-\d{8}
源码:

[C#] 纯文本查看 复制代码

        /// <summary>
        /// 匹配推荐码
        /// </summary>
        /// <param name="s">获取到的网页源码</param>
        private static void GetCode(string s)
        {
            Regex rg = new Regex(@"AAAYUN.{13}-\d{8}", RegexOptions.Multiline | RegexOptions.Singleline);
            MatchCollection matches = rg.Matches(s);
            DateTime dt = DateTime.Now;
            foreach (Match item in matches)
            {
                string value = item.Value;
                DateTime time = DateTime.ParseExact(value.Substring(20, 8), "yyyyMMdd", System.Globalization.CultureInfo.CurrentCulture);
                if (time > dt)//排除已过期的推荐码
                    Console.WriteLine(value);
            }
        }
        /// <summary>
        /// Get请求
        /// </summary>
        /// <param name="url">Url</param>
        /// <returns></returns>
        private static string Get(string url)
        {
            string message = string.Empty;
            HttpWebRequest request;
            try
            {
                request = (HttpWebRequest)WebRequest.Create(url);
                request.Accept = "text/html, application/xhtml+xml, */*";
                request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)";
                request.KeepAlive = true;
                request.ProtocolVersion = HttpVersion.Version11;
                request.Timeout = 20000;
                ServicePointManager.Expect100Continue = false;
                HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                Stream responseStream = response.GetResponseStream();
                StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                message = reader.ReadToEnd();
                reader.Close();
                responseStream.Close();
            }
            catch (Exception err)
            {
                message = err.Message;
            }
            return message;
        }
