Node.js mongoose需要true req.body.name{}

如果我将required设置为false，它将成功地在MongoDB数据库中创建一个具有一个id的对象。我有时会感到困惑，如果需要，请检查我的配置文件。我认为这是一件小事。如果你需要更多信息，只需评论

app.js

var express = require('express');
var bodyParser = require('body-parser');
var product = require('./routes/product'); // Imports routes for the products
var app = express();
var mongoose = require('mongoose'); // Set up mongoose connection

var dev_db_url = 'mongodb://localhost/Product';
var mongoDB = process.env.MONGODB_URI || dev_db_url;
mongoose.connect(mongoDB, {useNewUrlParser: true, useUnifiedTopology: true});
mongoose.Promise = global.Promise;
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'MongoDB connection error:'));

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use('/products', product);


var port = 3002;

app.listen(port, () => {
    console.log('Server is up on port numbner ' + port);
});

model.js

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

var ProductSchema = new Schema({
    name: {type: String, required: true, max: 100},
    price: {type: Number, required: true},
});

module.exports = mongoose.model('Product', ProductSchema);

controller.js

var Product = require('../models/product');

//Simple version, without validation or sanitation
exports.test = function (req, res) {
    res.send('Greetings from the Test controller!');
};

exports.product_create = function (req, res, next) {
    var product = new Product(
        {
            name: req.body.name,
            bags: req.body.bags
        }
    );
    console.log(JSON.stringify(req.body))
    product.save(function (err) {
        if (err) {
            return next(err);
        }
        res.send('Bags Created successfully')
    })
};

路由器.js

var express = require('express');
var router = express.Router();

// Require the controllers WHICH WE DID NOT CREATE YET!!
var product_controller = require('../controllers/product');

// a simple test url to check that all of our files are communicating correctly.
router.get('/test', product_controller.test);


router.post('/create', product_controller.product_create);

module.exports = router;

你能帮忙吗？

如何创建和保存产品对象？@mauliksakida Product.save（function..controller.I是否缺少其他内容？您还更改了什么？我得到了{}从console.log.ValidationError:Product validation failed:name:Path

name

是必需的。第二个参数相同。从上面的示例中，我使用的是数据名称和价格，这就是为什么我将

req.body.bags

从您的更改为'req.body.price'。两者都是{}…您如何从postman获取并接收值？无论我发布的结果始终相同，如果您在

console.log（req.params）

和

console.log（req.body）中出错，您都将得到结果{}

。请确保这样做没有错，因为我首先尝试了上面所写的内容，得到了预期的结果。我以前做过这种API并使用过Postman，但这次对req.body或req.params都不起作用。我现在退出并接受您的答案。感谢您的输入
