email 发送邮箱修改密码_nodejs邮箱修改密码-优快云博客

这篇博客详细介绍了如何使用PHP编程语言来发送电子邮件，特别是在用户需要修改密码的场景下。通过实例代码和步骤解析，阐述了实现这一功能的关键技术和注意事项。

首先是 index.php

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">

<body>
     <h2>找回密码</h2>
     <p class="demo"></p>
   <form action="">
      <table>
         <tr>
            <td>用户名：</td>
            <td><input type="text" id="username"/></td>
         </tr>
         <tr>
            <td>邮箱：</td>
            <td><input type="text" class="input" name="email" id="email"><span id="chkmsg"></span></td>
         </tr>
         <tr>
            <td><input type="button" class="btn" id="sub_btn" value="提 交"></td>
            <td></td>
         </tr>
      </table>
   </form>
</body>
</html>
<script src="jq.js"></script>
<script>
    $(function(){
        $("#sub_btn").click(function(){

            var username=$("#username").val();
            var email = $("#email").val();
            var preg = /^\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/; //匹配Email
            if(email=='' || !preg.test(email)){
                $("#chkmsg").html("请填写正确的邮箱！");
            }else{
                $("#sub_btn").attr("disabled","disabled").val('提交中..').css("cursor","default");
                $.post("sendmail.php",{mail:email,username:username},function(msg){
//                    if(msg=="noreg"){
//                        $("#chkmsg").html("该邮箱尚未注册！");
//                        $("#sub_btn").removeAttr("disabled").val('提 交').css("cursor","pointer");
//                    }else{
                        $(".demo").html("<h3>"+msg+"</h3>");
//                    }
                });
            }
        });
    })
</script>

然后  sendmail.php

<?php
include_once("connect.php");//连接数据库
include_once('class.phpmailer.php');
$username=$_POST['username'];
$email = stripslashes(trim($_POST['mail']));

$sql = "select uid,username,pwd from `user` where `username`='$username'";
$re = $pdo->query($sql);
    $row =$re->fetch(PDO::FETCH_ASSOC);
    $getpasstime = time();
    $uid = $row['uid'];
    $token = md5($uid.$row['username'].$row['pwd']);//组合验证码
    $url = "http://localhost/xiaoer/zhoukao1/reset.php?email=".$email."
    &token=".$token;//构造URL
    $time = date('Y-m-d H:i');

//邮箱标题
    $emailsubject = "找回密码";
//拼接邮箱内容
    $emailbody= "亲爱的".$email."：<br/>您在".$time."提交了修改密码请求。请点击下面的链接重置密码
    （按钮24小时内有效）。<br/><a href='".$url."'target='_blank'>".$url."</a>";
    $result = sendmail($emailsubject,$emailbody,$username,$email);
    if($result==1){//邮件发送成功
        $msg = '系统已向您的邮箱发送了一封邮件<br/>请登录到您的邮箱及时重置您的密码！';
        //更新数据发送时间
        $pdo->query("update `user` set `getpasstime`='$time' where uid='$uid '");
    }else{
        $msg = $result;
    }
    echo $msg;
//}

//发送邮件
function sendmail($emailsubject,$emailbody,$username,$email){

    $mail= new PHPMailer();
    /*服务器相关信息*/
    // $mail->SmtpMail.SmtpServer = "127.0.0.1";
    $mail->IsSMTP();                        //设置使用SMTP服务器发送
    $mail->SMTPAuth   = true;               //开启SMTP认证
    $mail->Host       = 'smtp.163.com';        //设置 SMTP 服务器,自己注册邮箱服务器地址
    $mail->Username   = '';        //发信人的邮箱名称
    $mail->Password   = '';          //发信人的邮箱密码
    /*内容信息*/
    $mail->IsHTML(true);                  //指定邮件格式为：html
    $mail->CharSet    ="UTF-8";               //编码
    $mail->From       = '';        //发件人完整的邮箱名称
    $mail->FromName   = $username;        //发信人署名
    $mail->Subject    = $emailsubject;            //信的标题
    $mail->MsgHTML($emailbody);              //发信主体内容
    //$mail->AddAttachment("15.jpg");       //附件
    /*发送邮件*/
    $mail->AddAddress($email);            //收件人地址
    //使用send函数进行发送
    if($mail->Send()) {
        return true;
    } else {
        self::$error=$mail->ErrorInfo;
        return   false;

    }
}

?>
reset.php<?php
header("content-type:text/html;charset=utf-8");
include_once("connect.php");//连接数据库
$token = stripslashes(trim($_GET['token']));
$email = stripslashes(trim($_GET['email']));
$sql = "select * from `user` where email='$email'";

$query = $pdo->query($sql);
$row =$query->fetch(PDO::FETCH_ASSOC);

if($row){
    $pwd=$row['pwd'];
    $mt = md5($row['uid'].$row['username'].$row['pwd']);
    if($mt==$token){

        $mydate=strtotime($row['getpasstime']);
        if(time()-$mydate>24*60*60){
            $msg = '该链接已过期！';
        }else{
            //重置密码...
              此处略过
            //$msg =include_once('update.php');
        }
    }else{
        $msg =  '无效的链接';
    }
}else{
    $msg =  '错误的链接！';
}
echo $msg;
?>
