问题描述
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 文档声明不推荐使用 Joi.validate 并且应该使用 schema.validate 但这对我也不起作用。邮递员只是挂起,直到我必须手动取消请求。以下是发出帖子请求以创建用户时的代码:
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 架构看起来像这些..
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..

解决方法
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);
应该是:
schema.validate(data);
check out .validate documentation for more information
-- 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);
错误甚至不存在,应该是
if(validation.error) {
}
-- 您的 try 应该放在函数的顶部:
router.post('/register',async (req,res) => {
try {
} catch (err) {
}
})
-- 而且,我不确定您是否正确导出了registervalidation,但应该是:
module.exports = { registervalidation }
