Question

我在我的网站上开发登录方法，但我在 login.controller.js 中遇到问题我有这个错误：

TypeError：无法读取属性＆＃39; message＆＃39;未定义的。
at login.controller.js：35

'use strict';

export default class LoginController {
  user = {
    name: '',
    email: '',
    password: ''
  };
  errors = {
    login: undefined
  };
  submitted = false;


  /*@ngInject*/
  constructor(Auth, $state) {
    this.Auth = Auth;
    this.$state = $state;
  }

  login(form) {
    this.submitted = true;

    if(form.$valid) {
      this.Auth.login({
        email: this.user.email,
        password: this.user.password,
        rememberme: this.user.remember
      })
        .then(() => {
          // Logged in, redirect to home
          this.$state.go('main');
        })
        .catch(err => {
          this.errors.other = err.message;
        });
    }
  }

}

export default class LoginController {
  /* @ngInject */
  constructor(Auth, $state) {
    this.Auth = Auth;
    this.$state = $state;
    this.user = {
      name: null,
      email: null,
      password: null
    };
    this.errors = {
      login: null,
      others: null // This was needed;
    };
    this.submitted = false;
  }

  login(form) {
    this.submitted = true;

    if (form.$valid) {
      this.Auth.login({
        email: this.user.email,
        password: this.user.password,
        rememberme: this.user.remember
      })
      .then(() => {
        return this.$state.go('main');
      })
      .catch((err) => {
        console.log(err); // see what 'err' looks like here
        this.errors.other = err.message;
      })
      .finally(() => {
        // Logged in, redirect to home
        console.log('last thing');
      });
    }
  }
}

我将变量移动到构造函数中。放入console.log以查看错误的样子。错误可能不存在'消息'。还需要声明this.errors.others。
