邮差发布请求中未插入猫鼬模型密钥(Mongoose model keys not being inserted in Postman post request)

 我试图使用下面的post方法来创建新文档。 但是当我在Postman中发送一个post请求（例如http：// localhost：3000 / api / posts？title = HeaderThree ）时，会创建一个新文档，但是键和值都会丢失。 
 
router.route('/posts')
    .get(function(req, res) {
        Post.find(function(err, posts) {
            if (err) { return res.send(err)}
            res.json(posts)
        })
    })
    .post(function(req, res) {
        const post = new Post(
            {
                title: req.body.title,
                text: req.body.text
            }
        );

        post.save(function(err, post) {
            if (err) { return res.send(err)};
            res.json({ message: 'Post added!'});
        });
    });
 
 架构是这样的： 
 
const mongoose = require('mongoose');

const Schema = mongoose.Schema;

const PostSchema = new Schema(
    {   
        date: {type: Date, default: Date.now},
        title: {type: String},
        text: {type: String },
        comments: {type: Array}
    }
)

module.exports = mongoose.model('PostSchema', PostSchema);

I'm trying to use the post method below to create new documents. But when I send a post request in Postman (e.g. http://localhost:3000/api/posts?title=HeaderThree) a new document is created but the keys and values are missing. 
 
router.route('/posts')
    .get(function(req, res) {
        Post.find(function(err, posts) {
            if (err) { return res.send(err)}
            res.json(posts)
        })
    })
    .post(function(req, res) {
        const post = new Post(
            {
                title: req.body.title,
                text: req.body.text
            }
        );

        post.save(function(err, post) {
            if (err) { return res.send(err)};
            res.json({ message: 'Post added!'});
        });
    });
 
The schema is this:
 
const mongoose = require('mongoose');

const Schema = mongoose.Schema;

const PostSchema = new Schema(
    {   
        date: {type: Date, default: Date.now},
        title: {type: String},
        text: {type: String },
        comments: {type: Array}
    }
)

module.exports = mongoose.model('PostSchema', PostSchema);
