如何获得Koa服务器URL路由列表

Question

I'm developing a mock server using koajs, and i would like to publish a service which lists developed APIs.

I use koa-router for mouting services.

And i would like somethink like:

var business_router = require('./controllers/router');
app.use(business_router.routes());   
app.use(business_router.allowedMethods());

console.log(app.listRoutes());

Although I guess it is not part of the official koa-router API, you can do as following:

var app = require('koa')();
var router = require('koa-router')();

router.get('/bar', function*() { this.body = 'Hi'; }});
router.get('/bar/foo', function*() { this.body = 'Hi'; }});
router.get('/foo', function*() { this.body = 'Hi'; }});
router.get('/bar/baz', function*() { this.body = 'Hi'; }});

app
  .use(router.routes())
  .use(router.allowedMethods());

console.log(router.stack.map(i => i.path));
// ['/bar', '/bar/foo', '/foo', '/bar/baz']

In your case, assuming business_router is an instance of koa-router :

console.log(business_router.stack.map(i => i.path));
