我无法访问任何请求参数。例如req.body.username
。由于某种原因,req.body总是未定义的。端点为/youtube
app.js
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var index = require('./routes/index');
var users = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', index);
app.use('/users', users);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error('Not Found');
err.status = 404;
next(err);
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
server.js
var express = require("express");
var mysql = require('mysql');
var app = express();
var pool = mysql.createPool({
connectionLimit : 100, //important
host : 'localhost',
user : 'user',
password : 'pass',
database : 'db',
debug : false
});
var router = express.Router();// get an instance of the express Router
// middleware to use for all requests
router.use(function(req, res, next) {
// do logging
console.log('Incoming request');
next(); // make sure we go to the next routes and don't stop here
});
app.get("/",function(req,res){-
handle_database(req,res);
});
router.route('/youtube')
.post(function(req, res) {
console.log(req.body); // always undefined
})
.get(function(req, res) {
});
app.use('/api', router);
app.listen(3000);
console.log("Listening on port 3000....")
答案 0 :(得分:0)
在server.js中添加var app = express();
正下方的3行:
var bodyParser = require('body-parser');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
现在你的req.body不会是undefined
。
