如何在 Express 中获取所有已注册的路由? [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.现在我想用适当的方法列出所有已注册的路由.

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

例如，如果我已经执行了

E.g., if I have executed

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

我想检索一个对象(或类似的东西)，例如:

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

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

这可能吗，如果可能，怎么做?

Is this possible, and if so, how?

更新: 同时，我创建了一个名为 get-的 npm 包routes 从给定的应用程序中提取路由，解决了这个问题.目前，只支持 Express 4.x，但我想现在这很好.仅供参考.

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.

推荐答案

express 3.x

好的，我自己找到的……它只是 app.routes :-)

应用程序 - 使用 express()

app._router.stack

路由器 - 使用 express.Router()

router.stack

注意:堆栈也包含中间件功能，应该过滤以仅获取路由".

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