Sails JS 助手错误解决/拒绝

Question

我正在使用 Sails 中的帮助程序进行登录。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();
    }

  }

当我有 right email 和 password 时，问题出在 Helper 上意味着 return 一个 code: 200 虽然它 return s code: 404。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/通过电子邮件将其发送给 return 时也是如此。但是当我删除 return exits.success({code: 404}) 并输入正确的电子邮件和密码时，它 return 是正确的代码 (200)。我需要帮助修复它。

问题可能是您试图 return 错误代码作为 'success' 退出。在你的 exits 对象中，你应该创建一个像 notFound: { responseType: 'notFound' } 这样的对象，然后当你想在你的代码中使用它时，你可以做 return exits.notFound()。这是一个例子：https://sailsjs.com/documentation/concepts/actions-and-controllers#?actions-2
