express.json与bodyParser.json [英] express.json vs bodyParser.json

问题描述

我正在编写一个相对较新的应用程序，并且想知道应该使用哪个应用程序

I'm writing a relatively new app and was wondering which I should use:

express.json()

或

bodyParser.json()

我可以假设他们做同样的事情.

Can I assume they do the same thing.

我想只使用express.json()，因为它已经内置.

I would like to just use express.json() as it is built in already.

推荐答案

Express的早期版本曾经捆绑了很多中间件. bodyParser是随之而来的中间件之一.当Express 4.0发布时，他们决定从Express中删除捆绑的中间件，而是将它们变成单独的程序包.然后，在安装bodyParser模块之后，语法从app.use(express.json())更改为app.use(bodyParser.json()).

Earlier versions of Express used to have a lot of middleware bundled with it. bodyParser was one of the middlewares that came it. When Express 4.0 was released they decided to remove the bundled middleware from Express and make them separate packages instead. The syntax then changed from app.use(express.json()) to app.use(bodyParser.json()) after installing the bodyParser module.

bodyParser在4.16.0版中重新添加到Express中，因为人们希望它像以前一样与Express捆绑在一起.这意味着如果您使用的是最新版本，则不必再使用bodyParser.json().您可以改用express.json().

bodyParser was added back to Express in release 4.16.0, because people wanted it bundled with Express like before. That means you don't have to use bodyParser.json() anymore if you are on the latest release. You can use express.json() instead.
