javascript - 使用 Node js 创建 Mongodb ObjectId 时如何捕获错误

Question

var criteria = Mongoose.Types.ObjectId(payloadData.skillId),

当我传递不正确的Id时，会出现以下错误消息。

Error: Uncaught error: Argument passed in must be a single String of 12 bytes or a string of 24 hex characters

Answer 1

mongo _id 是 12 字节 BSON 类型 ObjectId

var mongoose = require('mongoose');

var id = '1111adda111';
// var id = payloadData.skillId;

console.log(mongoose.Types.ObjectId.isValid(id)); // false
var cond = mongoose.Types.ObjectId.isValid(id)

if (cond) {
    // do the required operation
} else {
    console.log('not a valid id');
}
