UnhandledPromiseRejection：错误：Joi 的消息选项无效

Question

我收到无效的错误消息。 我尝试了很多东西，但没有任何效果。 Joi 文档 state 不推荐使用 Joi.validate 并且应该使用 schema.validate 但这对我也不起作用。Postman 只是挂起，直到我必须手动取消请求。 以下是发出创建用户的发布请求时的代码：

const { registervalidation } = require('../validation');

router.post('/register', async (req, res) => {

  //LETS VALIDATE
 const validation = registervalidation(req.body);
 if(error) return res.status(400).send(error.details);
 
const users = new User ({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password 
 });

try{
    const usersave = await users.save();
    res.send(usersave);
}
catch(err){
    res.status(400).send(err);
    console.log(err);
}
});

joi 模式看起来像这些..

const Joi = require('joi');

const registervalidation = data =>{

const schema = Joi.object({
    name:     Joi.string()
                 .alphanum()
                 .min(6)
                 .max(30)
                 .required()
                 .error(new Error('I am a custom error and I know it!')),

   email:     Joi.string()
                 .email({minDomainSegments: 2, tlds: { allow: ['com', 'net'] } })
                 .required()
                 .error(new Error('I am a custom error and I know it!')),

   password:  Joi.string()
                 .min(6)
                 .required()
                 .error(new Error('I am a custom error and I know it!'))
})
return schema.validate(data, schema);   

};

它抛出错误..

Answer 1

您的代码中有几个错误：

-- 您没有正确验证您的架构：

schema.validate(data, schema);

它应该是：

schema.validate(data);

查看 out.validate 文档以获取更多信息

-- 这不是你应该如何捕捉验证错误：

const validation = registervalidation(req.body);
if(error) return res.status(400).send(error.details);

错误甚至不存在，应该是

if(validation.error) {
    
}

-- 你的尝试应该放在 function 的顶部：

router.post('/register', async (req, res) => {
  try {
  
  } catch (err) {

  }
})

-- 而且，我不确定您是否正确导出了registervalidation ，但它应该是：

module.exports = { registervalidation }
