密码找回是几乎所有Web应用都需要的,一般均通过邮件的方式,这里我先实现一种最简单的密码找回——将密码重置为随机字符串后发送邮件通知,发送邮件要用到nodemailer,版本是0.7.0
- 页面的代码,比较简单,但还是放上来吧

- Angular控制器部分代码
Controllers.controller('FPCtrl',function($scope,$http,checkUser){
$scope.form={};
$scope.display=false;
$scope.msg='';
$scope.findPassword=function(){
console.log($scope.form);
var err=null;
err=checkUser($scope.form,'forgetPassword');
if(err){
$scope.msg=err;
$scope.display=true;
}
else{
$scope.msg="邮件正在发送中,请耐心等待";
$scope.display=true;
$http.post('/forgetPassword',$scope.form).success(function(data){
console.log(data.err);
if(data.err){
$scope.msg=data.err.message;
$scope.display=true;
}
else{
$scope.msg="密码重置邮件已发送,注意查收";
$scope.display=true;
}
}).error(function(data){
$scope.msg='未知错误,请重试';
$scope.display=true;
});
}
}
});
- 后端代码
var smtpTransport=nodemailer.createTransport('SMTP',{
service:'Gmail',
auth:{
user:yourname,
pass:your password
}
});
function forgetPassword(req,res){
var tmp=req.body;
var udoc;
var newPassword=tool.randomString(8);
Then(function(cont){
User.findOne({username:tmp.username},cont);
}).then(function(cont,doc){
if(!doc) return cont(new Err(msg.USER.userNone));
if(doc.email!==tmp.email) return cont(new Err('填写的邮件与预留邮件地址不一致'));
udoc=doc;
console.log(newPassword);
var mailoptions={
from:'USF-noReply',
to:doc.email,
subject:'密码重置',
html:'
<h3>新密码是'+newPassword+'</h3>
'
};
smtpTransport.sendMail(mailoptions,cont);
}).then(function(cont,info) {
udoc.password = tool.SHA256(newPassword).toString();
udoc.password = tool.HmacSHA256(udoc.password, 'ustc').toString();
udoc.password = tool.MD5(udoc.password);
udoc.save(cont);
}).then(function(cont,doc){
res.json({
success:true,
err:null
});
}).fail(function(cont,err){
if(!err.message) err.message='后台错误,稍后再试';
res.json({
success:false,
err:err
});
});
}
写完自己感觉都很逗比的说,其实正统的密码找回方式应该是生成一个由用户名+邮件地址+过期时间加密后的token,并把它存入缓存中,发邮件将相应的token转成url给用户,用户点击之后跳到密码重置的页面,不过由于懒得加redis缓存,就先用这种很坑爹的方式将就以下,等加上redis缓存之后再全部更改吧。
