正则表达式问题

Question

productList.aspx?m=2&n=3&p=4
求怎么把m、n、p的值用正则表达式的\d去替换，这个写法该怎么写。
m、n、p不一定是一位数，可能是55...

Answer 1

(?i)productList\.aspx\?m=\d+&n=\d+&p=\d+

Answer 2

参数用个aes加密就行了。接收再解密

WebRequest wReq = WebRequest.Create(Url);
            WebResponse wResp = wReq.GetResponse();
            Stream respStream = wResp.GetResponseStream();
            StreamReader reader = new StreamReader(respStream, System.Text.Encoding.GetEncoding("utf-8"));
            str = reader.ReadToEnd();
            StreamWriter sw = new StreamWriter(HttpContext.Current.Server.MapPath("../../") + furl_html, false, System.Text.Encoding.GetEncoding("utf-8"));
            
            //yourhtml是需要替换的,html是替换成的
            string yourhtml = @"(?i)productList\.aspx\?mid=\d+";
            string html = "";
            html = Regex.Replace(yourhtml, @"(?i)(?<=(['""]?))(\w+)\.aspx(\?[^?'""]+)?(?=\1)",
            delegate(Match ma) { return string.Format("{0}.html", ma.Groups[2].Value + ma.Groups[3].Value.Replace("&", "_").Replace("?", "_").Replace("=", "")); });
            str = str.Replace(yourhtml, html); 
            sw.Write(str);
            sw.Flush();
            sw.Close();兔子督察，帮忙看看，页面内类似yourhtml的内容没有替换掉，是什么原因？

Answer 4

你的 yourhtml 应该是上边那段HTML才对

Answer 5

上边那段就是str
str = str.Replace(yourhtml, html);
