BodyParser Express，我在Object中有Object

Question

我正在尝试在服务器上发布一些数据，但不起作用，因为我得到类似{＆＃39; {\ n＆＃34; rate＆＃34; ：＆＃34; 26＆＃34; \ n}＆＃39;：＆＃39;＆＃39; }。

---- App.js

const express     = require('express'),
      mongoose    = require('mongoose'),
      bodyParser  = require('body-parser');

const db            = mongoose.connect('mongodb://localhost/invoiceAPI');
      app           = express(),
      port          = process.env.PORT || 3000,
      Rate          = require('./models/rateModel'),
      Client        = require('./models/clientModel'),
      Invoice       = require('./models/invoiceModel');

app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());

const invoiceRouter = require('./routes/invoiceRoutes')(Invoice),
      clientRouter  = require('./routes/clientRoutes')(Client),
      rateRouter    = require('./routes/rateRoutes')(Rate);

app.use('/api/invoices', invoiceRouter);
app.use('/api/clients', clientRouter);
app.use('/api/rates', rateRouter);

app.listen(port, () => {
    console.log('Gulp is running on port ' + port);
});

--- rateRoutes文件：

const express = require('express');

const rateRoutes = (Rate) => {
    const rateRouter = express.Router();

    rateRouter.route('/')
      .get((req,res) => {
          Rate.find((err,rates) => {
            if(err){
              res.status(500).send(err);
            }
            else res.json(rates);
          });
      })
      .post((req,res) => {
        console.log(req.body);
        let rate = new Rate(req.body);
        rate.save();
        res.status(201).send(rate);
      });
    return rateRouter;
}

module.exports = rateRoutes;

当我用{＆＃34; rate＆＃34;：26}执行帖子时，我得到了 {＆＃39; {\ n＆＃34; rate＆＃34; ：＆＃34; 26＆＃34; \ n}＆＃39;：＆＃39;＆＃39; }

我读了一些关于bodyParser顺序的内容，但是没有用。
