ExpressJs请求正文显示未定义

Question

我是ExpressJ的新手，我想执行POST请求，但无法使Body Parser正常工作

const express = require("express");
const path = require("path");
const config = require("./config");
// const logger = require("./middleware/logger")

// init express
const app = express();

// set 'public' as STATIC directory
app.use(express.static(path.join(__dirname, "public")));

// init middleware
// app.use(logger);

// setup parent router for api/people
app.use('/api/people', require("./routes/api/members"));

// adding body parser middleware
app.use(express.json());
app.use(express.urlencoded({ extended: false }));


// set PORT listen
app.listen(config.PORT, () =>
  console.log(
    `damiisdandy's server running on port ${config.PORT}... at ${config.time}`
  )
);

这里是路由文件

const express = require('express')
const uuid = require('uuid')
const config = require('../../config')
const router = express.Router();


router.post("/", (req, res) => {
    res.send(req.body)
    console.log(req.body)
    // const newMember = {
    //     id: uuid.v4(),
    //     name: req.body.name,
    //     email: req.body.email,
    //     active: true,
    // }
    // if(!newMember.name || !newMember.email) {
    //     return res.status(400).json({
    //         msg: "Please Fill in the Name or Email"}
    //     );
    // }
    // config.PEOPLE.push(newMember);
    // res.json(config.PEOPLE);
})

module.exports = router

[我希望快速响应，我什至尝试了“ body-parser”模块，但这似乎也不起作用..我被卡住了..请问我该怎么办？

Answer 1

您的index.js文件中是否有3行？

// import body parser
const bodyParser = require('body-parser');

// support parsing of application/json type post data
app.use(bodyParser.json());

//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({ extended: true }));
