投影不适用于查找查询 [英] projection not working with find query

问题描述

您好，我想按查询排除某些字段.我正在使用nodejs

Hello I'd like to exclude some fields by query,. Im using nodejs

public async getDoc() {
        return new Promise((resolve, reject) => {
            this.database.collection('users').find({email: "value3"}, {password: 0}).toArray((err, result) => {
                if(err) {
                    reject(err)
                }
                resolve(result);
            });
        })
    }

但是在结果集中，我一直在获取密码字段.

but in the result set I keep getting password field..

推荐答案

投影不适用于新的nodejs mongodb驱动程序...而是必须使用

Projection doesn't work with the new nodejs mongodb driver... Instead you will have to use .project() cursor method here

this.database.collection('users')
  .find({ "email": "value3" })
  .project({ "password": 0 })
  .toArray();
