2017-6-10 ASP.NET邮箱认证并进行判断
实现效果：客户输入邮箱地址，向客户邮箱中发送一条验证码（有效时间为20分钟），客户根据邮箱中的验证码，输入验证，并进行判断
实现效果图：
页面代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> </head> <body> <form id="form1" runat="server"> <div> 请输入接收地址：<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <%-- 对输入邮箱格式的正确与否进行提示 --%> <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label><br /> <asp:Button ID="Button1" runat="server" Text="获取验证码" /><br /> 请输入邮箱验证码：<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox> <asp:Button ID="Button2" runat="server" Text="判断" /><br /> <%-- 验证正确进行提醒 --%> <asp:Label ID="Label3" runat="server" Text="Label"></asp:Label><br /> <asp:HiddenField ID="HiddenField1" runat="server" /> </div> </form> </body> </html> <script type="text/javascript"> //正则表达式，对邮箱格式进行判断 document.getElementById("TextBox1").onkeyup = function () { var s = document.getElementById("TextBox1").value; if (/^[A-Za-z\d]+([-_.][A-Za-z\d]+)*@([A-Za-z\d]+[-.])+[A-Za-z\d]{2,4}$/.test(s)) { document.getElementById("Label1").innerText = "邮箱正确"; } else { document.getElementById("Label1").innerText = "邮箱错误"; } } </script>
后台代码：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Net; using System.Net.Mail; public partial class _Default : System.Web.UI.Page { string yzm = null; protected void Page_Load(object sender, EventArgs e) { Button1.Click += Button1_Click; Button2.Click += Button2_Click; } //根据用户输入的内容和session中存放的内容进行比较 void Button2_Click(object sender, EventArgs e) { string aa = TextBox4.Text; if (aa == Session["yzm"].ToString()) { Label3.Text = "验证成功"; } else { Label3.Text = "验证失败"; } } void Button1_Click(object sender, EventArgs e) { //发送邮件的地址，标题，内容 string to = TextBox1.Text; //创建发送邮件的q服务器对象先引用命名空间 SmtpClient smtp = new SmtpClient("smtp.qq.com"); smtp.EnableSsl = true; smtp.UseDefaultCredentials = false; //发件人的地址 MailAddress from = new MailAddress("2580497963@qq.com"); //收件人的地址 MailAddress t = new MailAddress(to); //发送的邮件来自哪里，发送给谁 MailMessage mail = new MailMessage(from, t); //给邮件标题赋值 mail.Subject = "欢迎注册xx平台"; //给邮件内容赋值 //随机生成一个4位数的验证码，让客户输入，判断验证码是否正确 Random r = new Random(); yzm = null; for (int i = 0; i < 4;i++ ) { yzm+=r.Next(0,100); } //将生成的验证码存入session中 Session["yzm"] = yzm; mail.Body = yzm; //创建证书对象 NetworkCredential net = new NetworkCredential("2580497963", "dzdeexcfposfecea"); //设置资格证书 smtp.Credentials = net; //发送邮件 smtp.Send(mail); } }
