Express.js中不推荐使用的替代body解析器的方法 [英] Non-deprecated alternative to body-parser in Express.js

问题描述

我正在阅读《使用Node和Express进行Web开发》一书，遇到了麻烦.

I am going through the book Web Development with Node and Express and have hit a snag.

我被指示将以下内容放入我的应用程序文件中，但似乎已弃用了 body-parser ，并且无法正常工作.如何实现相同的功能?

I was instructed to put the below in my application file, but it looks like body-parser is deprecated and will not work. How can I achieve the same functionality?

这是我当前的代码:

app.use(require('body-parser')());

app.get('/newsletter', function(req, res){

    // we will learn about CSRF later...for now, we just
    // provide a dummy value
    res.render('newsletter', { csrf: 'CSRF token goes here' });
});

app.post('/process', function(req, res){

    console.log('Form (from querystring): ' + req.query.form); 
    console.log('CSRF token (from hidden form field): ' + req.body._csrf); 
    console.log('Name (from visible form field): ' + req.body.name); 
    console.log('Email (from visible form field): ' + req.body.email); res.redirect(303, '/thank-you');
});

推荐答案

来自: bodyParser已弃用表示4

这意味着，自2014年6月19日起，不推荐使用bodyParser()构造函数.

It means that using the bodyParser() constructor has been deprecated, as of 2014-06-19.

app.use(bodyParser()); //Now deprecated

您现在需要分别调用方法

You now need to call the methods separately

var bodyParser = require('body-parser');

app.use(bodyParser.urlencoded());

app.use(bodyParser.json());

以此类推.
