Joi 在验证猫鼬对象时抛出错误 -

Question

When I create an object of type Contact (which is a model of MongoDB schema) it throws some weird error as below. My purpose of using Joi is for Client-side validation aka incoming request.

Here auth is a middleware that is validating jwt and fetching out the id from jwt.

It is showing weird kind of error like - **"$__" is not allowed. "isNew" is not allowed. "errors" is not allowed. "_doc" is not allowed. "$locals" is not allowed. "$op" is not allowed **

router.post('/',auth,async (req,res)=>{
try{
// console.log(`contact - ${JSON.stringify(req.body)}`);
let contact = new Contact({
  firstName : req.body.firstName,
  lastName : req.body.lastName,
  email : req.body.email,
  address : req.body.address,
  country : req.body.country,
  isBookMark : req.body.isBookMark,
});
// console.log(`before contact - ${JSON.stringify(contact)}`);
// // contact = {...req.body};
// console.log(`before after - ${JSON.stringify(contact)}`);
contact.userID=req.user.id;
// ?console.log(`contact - ${(contact)}`);

const {error} = validateContact(contact);
console.log(`ERROR - ${error}`);
}
 catch(error){
console.log(`contacts - ${error.message}`);
}

The problem is that you are trying to validate the mongoose schema class which has its own internal properties. That is what you are seeing in the error. You have two choices here

• Instead of passing contact object, pass req.body to your validate function.

• Or extract properties from contact schema and pass that object to validate function.

Hope that helps.
