如何获取Express的所有注册路线？ [英] How to get all registered routes in Express?

问题描述

我有一个使用Node.js和Express构建的Web应用程序。现在我想使用适当的方法列出所有注册的路线。

例如，如果我执行了

  app.get（'/'，function（...）{...}）; 
 app.get（'/ foo /：id'，function（...）{...}）; 
 app.post（'/ foo /：id'，function（...）{...}）; 
  

我想要检索一个对象（或类似的东西），如：

  {
 get：['/'，'/ foo /：id']，
 post：[' foo /：id'] 
} 
  

这是可能吗？

更新：同时，我创建了一个名为 get-routes ，它从一个给定的应用程序中提取路由，从而解决了这个问题。目前，只支持Express 4.x，但是我猜想现在是没问题的。只是FYI。

解决方案

express 3.x

它自己...它只是 app.routes ： - ）

express 4.x

应用程序 - 使用 express（）

app._router.stack

路由器 - 用 express.Router（）

router.stack




注意：堆栈还包含中间件功能，应将其过滤到仅获取路线。

I have a web application built using Node.js and Express. Now I would like to list all registered routes with their appropriate methods.

E.g., if I have executed

app.get('/', function (...) { ... });
app.get('/foo/:id', function (...) { ... });
app.post('/foo/:id', function (...) { ... });

I would like to retrieve an object (or something equivalent to that) such as:

{
  get: [ '/', '/foo/:id' ],
  post: [ '/foo/:id' ]
}

Is this possible, and if so, how?

UPDATE: Meanwhile, I have created an npm package called get-routes that extracts the routes from a given application, which solves this issue. Currently, only Express 4.x is supported, but I guess for now this is fine. Just FYI.

解决方案

express 3.x

Okay, found it myself ... it's just app.routes :-)

express 4.x

Applications - built with express()

app._router.stack

Routers - built with express.Router()

router.stack

Note: The stack includes the middleware functions too, it should be filtered to get the "routes" only.
