如何在快速路由器中使用body-parser? [英] How to use body-parser in express router?

问题描述

我有一个具有对象的api，但我无法在控制台中打印其未定义的状态，我以为我缺少body-parser，但是在添加body-parser之后，我看到了错误 body-parser不推荐使用的bodyParser:使用单个json/urlencoded中间件任何帮助将不胜感激.

I have a post api that has object but i am not able to print in console its throowing undefined i thought i am missing body-parser but after adding body parser i see error body-parser deprecated bodyParser: use individual json/urlencoded middlewares Any help will be appreciated.

routes.js

routes.js

var express = require('express');
var bodyParser = require('body-parser');
var Diagram = require('./api/diagram/diagram.controller');
var router = express.Router();
router.post('/saveUpdateDiagram',bodyParser,function(req,res){
    console.log(req.body);
});

app.js

var express = require('express');
var path = require('path');
var app = express();
var bodyParser = require('body-parser');
var router = express.Router();
var route = require('./server/routes').router;
var mongoose = require('mongoose');
mongoose.connection.on('connected', function() {
    console.log('MongoDB connected ');
});


app.use(express.static(path.join(__dirname, 'public')));
app.use('/', route);
app.use(bodyParser.urlencoded({
    extended: false
}))
app.use(bodyParser.json())


app.listen(8760, function() {
    console.log('I am listening 8760...');
});

推荐答案

您在app.js中使用body-parser很好.它是中间件，并加载有app.use，因此它将应用于每个传入的请求.

Your use of body-parser in app.js is fine. It is middleware, and it is loaded with app.use so that it will be applied to every incoming request.

您可以在routes.js中将其删除，使其看起来像这样:`

You can remove it in routes.js, so that it looks like so:`

var express = require('express');
var Diagram = require('./api/diagram/diagram.controller');
var router = express.Router();
router.post('/saveUpdateDiagram', function(req,res){
    console.log(req.body);
});

`另外，请尝试更换:

app.use(bodyParser.urlencoded({
    extended: false
}))

具有:

app.use(bodyParser.urlencoded({extended: true}));
