Javascript Mongoose上的Post请求与Get请求不匹配

我的MongoDB Atlas上存储的内容与我的post请求不匹配。我的数据库中只存储用户名，尽管post请求和模式中有tweet和日期。如何在数据库中显示推文和日期？谢谢

MONGODB模式：

const mongoose = require("mongoose");

const Schema = mongoose.Schema;

const tweetSchema = new Schema(
  {
    username: {
      type: String,
      required: true
    }
  },
  {
    tweet: {
      type: String,
      required: true,
      maxlength: 140
    }
  },
  {
    date: {
      type: Date,
      required: true
    }
  },
  {
    timestamps: true
  }
);

const Tweet = mongoose.model("Tweet", tweetSchema);

module.exports = Tweet;

快速路由器：

const router = require("express").Router();
let Tweet = require("../models/tweet.model");

router.route("/").get((req, res) => {
  Tweet.find()
    .then(tweet => res.json(tweet))
    .catch(err => res.status(400).json("Error: " + err));
});

router.route("/add").post((req, res) => {
  const tweet = req.body.tweet;
  const username = req.body.username;
  const date = Date.parse(req.body.date);

  const newTweet = new Tweet({
    username,
    tweet,
    date
  });

  newTweet
    .save()
    .then(() => res.json("Tweet added!"))
    .catch(err => res.status(400).json("Error: " + err));
});

module.exports = router;

后请求：

{
    "username": "yourfatuncle",
    "tweet": "first tweet",
    "date": "2020-03-19T08:28:49.271+00:00"
}

获取请求：

 {
        "_id": "5e6f48d349a86510646354ae",
        "username": "yourfatuncle",
        "__v": 0
    }

试试这个：

const tweetSchema = new Schema(
  {
    username: {
      type: String,
      required: true
    },
    tweet: {
      type: String,
      required: true,
      maxlength: 140
    },
    date: {
      type: Date,
      required: true
    }
  },
  {
    timestamps: true
  }
);

试试这个：

const tweetSchema = new Schema(
  {
    username: {
      type: String,
      required: true
    },
    tweet: {
      type: String,
      required: true,
      maxlength: 140
    },
    date: {
      type: Date,
      required: true
    }
  },
  {
    timestamps: true
  }
);

尝试更改：

newtweet（{username:username，Tweet:Tweet，date:date}）

仍然不起作用：*（您有错误的模式要更改：

newtweet（{username:username，Tweet:Tweet，date:date}）

仍然不起作用：*（您有错误的模式）
