node.js - API 帖子，空主体对象

Question

当我发布详细信息时，我正在尝试使用 node 和“body-parser”来设置基本 API:

localhost:3000/users?email=test.com&givenName=test

我的 req.body.email 为空，如何发布我的详细信息？我正在使用 body-parser 像这样:

// create express app
const app = express();

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: true }))

// parse application/json
app.use(bodyParser.json())

我的 Controller :

exports.create = (req, res) => {
    // Validate request
    if (!req.body.email) {
        return res.status(400).send({
            message: "user cannot be empty"
        });
    }

    // Create a user
    const user = new user({
        email: req.body.email || "No Emails",
        givenName: req.body.givenName || "No Emails",
        familyName: req.body.familyName || "No Emails"
    });

    // Save user in the database
    user
        .save()
        .then(data => {
            res.send(data);
        })
        .catch(err => {
            res.status(500).send({
                message:
                    err.message ||
                    "Some error occurred while creating the user."
            });
        });
};

我尝试了与您类似的代码，并且工作正常，请确保您正在点击来自 Postman 的 POST 请求。请参阅下面的代码，

'use strict';

// Initialize an Express application
const express = require('express');
const app = express();
const port = 8080;

// parse application/x-www-form-urlencoded
app.use(express.urlencoded({ extended: true }));

// parse application/json
app.use(express.json());

app.use((req, res) => {
    console.log(req.body);
    res.json(res.body);
});

// Start the express application
app.listen(port, () => {
    console.log(`server listening on port ${port}`);
});
