如何返回用户电子邮件

Question

我已经创建了帖子路线来将帖子存储在数据库中。这是一条受保护的路线，因此用户只有在输入登录详细信息后才能存储帖子。当我在邮递员中发帖时，我看到对象中没有返回用户电子邮件。即使在 mongodb 集合中，我也看不到与该帖子关联的电子邮件。如何在帖子对象中包含电子邮件。我不希望用户在发布时一次又一次地输入电子邮件，因为他们已经登录了。所以我有点想将电子邮件与帖子一起自动存储。希望我说得通。有人可以帮我解决这个问题吗？

现在对象有点像这样存储在 mongodb 的帖子集合中

_id: ObjectId("5f1a99d3ea3ac2afe5"),
text: "It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. ",
user:ObjectId("5f1a99d3eac2c82afe5"),
age:20,
country:"India",
gender:"male",
date:2020-07-24T08:23:35.349+00:00,
__v:0

我也想要上述对象中的电子邮件。

后模型

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

const PostSchema = new Schema ({
    user: {
        type: Schema.Types.ObjectId,
        ref: 'users'
    },
    text: {
        type: String,
        required: true
    },
    name: {
        type: String
    },
    
    email: {
            type: String
    }
    ,
    age: {
        type: Number,
        required: true
    },
    gender: {
        type: String,
        required: true
    },
    country: {
        type: String,
        required: true
    },
    date: {
        type: Date,
        default: Date.now
    }
})

module.exports = Post = mongoose.model('post', PostSchema)

发布路线

const express = require('express');
const router =  express.Router();
const auth = require('../../middleware/auth')
const { check, validationResult} = require('express-validator');
const User = require('../../models/User')
const Post = require('../../models/Post')
router.post('/', [auth, [
    check('text', 'Text is required').not().isEmpty()
]], async (req,res)=>{
    const errors = validationResult(req);
    if(!errors.isEmpty()){
        return res.status(400).json({errors: errors.array()})
    }

   
    try {
        const user = await (await User.findById(req.user.id)).isSelected('-password')

    const newPost = new Post({
        text: req.body.text,
        name: user.name,
        user: req.user.id,
        age: req.body.age,
        country: req.body.country,
        gender: req.body.gender,
        email: req.user.email // this email is not stored with the post and I want this to be automatically posted in the collection without the user having to type it again to save the post
    })
    const post = await newPost.save();
    res.json(post);

    } catch (err) {
        console.error(err.message);
        res.status(500).send('Server Error')
    }
})

module.exports = router;

用户模型

const mongoose = require('mongoose');
const UserSchema = new mongoose.Schema({
    name: {
        type: String,
        required: true
    },
    email: {
        type: String,
        required: true,
        unique: true
    },
    password: {
        type: String,
        required: true
    },
    date: {
        type: Date,
        default: Date.now
    }
})

module.exports = User = mongoose.model('user', UserSchema);

Answer 1

将isSelected 更改为select

const user = await (await User.findById(req.user.id)).isSelected(password')

Answer 2

我可能在这里看到的问题是，一旦你抓住了用户的对象，你仍然指的是req.user.email而不是user.email。

如果这不能解决您的问题，请尝试 console.log 在User.findById 之后返回的用户

更新： 你可以看到here isSelected 返回布尔值。所以你必须得到true，因为在user 中有密码字段。也代替req.user.email 使用user.email
