Write a page to check whether the Alibaba Cloud account exists

I was bored and wrote a page for Alibaba Cloud account registration before, mainly to check whether the account exists. Now share it:

Mainly implemented through webrequest:

1. Write an Alibaba Cloud email class:

using System;using System.Collections.Generic;using System.Web;/// <summary>/// Summary description for AliEmal/// </summary>public class AliEmail{    public ContentClass content;    public bool hasError;}public class ContentClass{    public string message;    public int status;    public bool success;}

2. Write an email verification class:

using System;using System.Collections.Generic;using System.Net;using System.Net.Mail;using System.Text;using System.Text.RegularExpressions;using System.Web;/// <summary>/// Summary description for Util/// </summary>public class AliUtil{    public AliUtil()    { }    //    // TODO: Add constructor logic here    //    #region 验证邮箱验证邮箱    /**/    /// <summary>    /// 验证邮箱    /// </summary>    /// <param name="source"></param>    /// <returns></returns>    public static bool IsEmail(string source)    {        return Regex.IsMatch(source, @"^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$", RegexOptions.IgnoreCase);

3. Write a simple front-end verification page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AliCheck.aspx.cs" Inherits="AliCheck" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">    <title></title></head><body>    <form id="form1" runat="server">    <div>        <div>            阿里云邮箱：            <asp:TextBox ID="AliEmailName" runat="server"></asp:TextBox>            <asp:Button ID="Check" runat="server" Text="检查是否存在" OnClick="Check_Click" />            <div style="color:red;" id="showError" runat="server"></div>         </div>    </div>    </form></body></html>

4. Write a verification page Backend:
