Question

这是我的代码我正在尝试用mysql制作api，数据库中的表已经插入了用户名和密码

const express = require('express');
const mysql = require('mysql');
const bodyParser = require('body-parser');
const app = express();
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));


const conn = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'fsoc',
    database: 'nodesql'
});
//connection 
conn.connect((err) => {
    if (err) {
        throw err;
    }
    console.log('Mysql Connected');
});

//Select query

app.get('/show', (req, res) => {
    let sql = 'SELECT * from users';
    conn.query(sql, (err, result) => {
        if (err) throw err;
        res.send(result[0]);
    });
    console.log(req.body);
});

app.listen(3000,()=>{
    console.log('check on 3000');
})

虽然在邮递员中它显示用户名和密码的JSON数据为 { "id": 2, "username": "ujju", "password": "fsoc11" }

您必须将get方法替换为post才能使req.body填充已发布的数据，同样在邮递员中您必须使用发布请求并提供一些表单数据：

app.post('/show', (req, res) => {

    console.log(req.body); //log posted data

    let sql = 'SELECT * from users';
    conn.query(sql, (err, result) => {
        if (err) throw err;
        res.send(result[0]);
    });

});

req.body甚至通过使用bodyParser
