使用Node.js发布请求内容

我试图从快速应用程序的路由移动到另一个文件，它的工作原理，但是当我试图获得发布请求的主体，它是未定义的。

这是server.js文件：

var winston = require('winston'); winston.remove(winston.transports.Console); winston.add(winston.transports.Console, {colorize: true}); winston.add(winston.transports.File, { filename: 'server.err', level: 'error'}); winston.info('Starting server.'); var Firebase = require('firebase-admin'); var connection = require('./connection/firebaseConnection.json'); var express = require('express') app = express(); var router = require('./srcs/router'); var bodyParser = require('body-parser'); try { Firebase.initializeApp({ credential: Firebase.credential.cert({ projectId: connection.firebase.project_id, clientEmail: connection.firebase.client_email, privateKey: connection.firebase.private_key }), databaseURL: 'https://' + connection.firebase.project_id + '.firebaseio.com' }); winston.info('Connected to Firebase.'); } catch (error) { winston.error('Could not connect to Firebase : ' + error.code + ' : ' + error.message); process.exit(1); } app.use('/', router); app.use(bodyParser.json({limit: '50mb'})); app.use(bodyParser.urlencoded({limit: '50mb', extended: true})); app.use(function(req, res, next) { var origin = req.headers.origin; res.setHeader('Access-Control-Allow-Origin', '*'); res.setHeader('Access-Control-Allow-Methods', 'POST', 'GET'); res.setHeader('Access-Control-Allow-Headers', 'Content-Type,X-Requested-With'); res.setHeader('Access-Control-Allow-Credentials', true); return next(); }); var server = app.listen(80, function() { winston.info('Server listening on port 80.'); }); 

这里是router.js

 var express = require('express'); var router = express.Router(); var winston = require('winston'); router.post('/post', function(req, res) { console.log(req.body); }); module.exports = router; 

我用这个命令做了一个curl：

 curl --data "title=test" http://localhost/post 

而router.post被触发，但值是未定义的。

尝试在路由器中间件调用之前添加bodyParser中间件（app.use调用）。

中间件按照添加顺序运行。 您希望bodyParser在到达路由器之前执行。

 app.use(bodyParser.json({limit: '50mb'})); app.use(bodyParser.urlencoded({limit: '50mb', extended: true})); app.use('/', router);
