Sails JS助手错误解析/拒绝

Question

我正在使用Sails中的Helpers进行登录。这是我的helpers/login.js:

fn: async function (inputs, exits) {
const password = inputs.password;
const email = inputs.email;
// find user with email
const user = await User.findOne({email});
if (user){
const salt = user.salt;
const hashedPass = user.password;
const iterations = user.iterations;
// check if input password matches with password in DB
crypto.pbkdf2(password, salt, iterations, 64, 'sha512',
(err, key) => {
if (!err) {
if (hashedPass === key.toString('hex')) {
// password matched
return exits.success({code: 200});
}
}
});
}
// account not found or password doesnt match
return exits.success({code: 404});

}

UserController.js：

login: async function(req, res){
let loginUser;
try {    
loginUser = await sails.helpers.login.with({
email: req.body.email, password: req.body.password
});

} catch (e) {
console.log("Error login in usercontroller ", e.message);
return res.serverError();
}
if (loginUser.code == 200) {
return res.ok();
}else {
return res.serverError();
}
}

问题在于Helper，当我拥有权限电子邮件和密码时，它意味着返回code: 200，尽管它返回code: 404。带有来自节点的错误消息：

WARNING: Something seems to be wrong with this function.
It is trying to signal that it has finished AGAIN, after
already resolving/rejecting once.
(silently ignoring this...)

，当我输入错误的用户名/电子邮件时，它也会返回该消息。但当我删除return exits.success({code: 404})并输入正确的电子邮件和密码时，它会返回正确的代码(200(。我需要帮忙修理。

问题可能是您试图将错误代码作为"成功"退出返回。在exits对象中，您应该创建一个类似notFound: { responseType: 'notFound' }的对象，然后当您想在代码中使用它时，您可以执行return exits.notFound()。以下是一个示例：https://sailsjs.com/documentation/concepts/actions-and-controllers#?actions-2
