UnhandledPromiseRejection:错误: Joi的无效消息选项
UnhandledPromiseRejection:错误: Joi的无效消息选项
提问于 2021-03-16 20:31:31
我收到的错误信息无效。我试过很多东西，但都没有用。Joi声明不推荐使用Joi.validate，应该使用schema.validate，但这对我不起作用，either.Postman只是挂起，直到我不得不手动取消请求。下面是创建用户的post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模式看起来如下..。
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..。

您的代码中有几个错误：
-您没有正确地验证您的模式：
schema.validate(data, schema);它应该是：
schema.validate(data);-这不是您应该如何捕获验证错误：
const validation = registervalidation(req.body);
if(error) return res.status(400).send(error.details);error甚至不存在，应该是
if(validation.error) {
}-您的try应该放在您的函数的顶部：
router.post('/register', async (req, res) => {
try {
} catch (err) {
}
})-而且，我不确定你是否正确地导出了你的registervalidation，但它应该是：
