自定义验证规则：

export default {
  data() {
    let verUserName = (rule, value, callback) => {
      if (value == 1) {
        return callback(new Error('用户名不能等于1'))
      }
    }
    return {
      formData: {
        username: '',
        password: '',
      },
      rules: {
        username: [
          {validator: verUserName, trigger: 'blur'}
        ]
      }
    };
  },
  methods: {
    login: () => {
      console.log(1)
    }
  }
}
