用koa路由器在koa中嵌套路由重定向

Question

如何使用koa-router做嵌套路由重定向？

app.js：

var router = require('koa-router')(); 
var route1 = require('./routes/route1'); 
var route2 = require('./routes/route2'); 

router.use('/route1', route1); 
router.use('/route2', route2); 

app.use(router.routes()); 

route1.js：

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

router.all('/', function *() { 
    router.redirect('/route2'); 
}); 

module.exports = router.routes(); 

route2.js：

導航到時

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

router.all('/', function *() { 
    this.body = "route2"; 
}); 

上面的代碼導致以下運行時錯誤/route1：

TypeError: Cannot read property '0' of undefined

啊，我需要學習閱讀。我解釋了koa-router文檔說router.redirect()打算在HTTP動詞功能中使用。

正確的使用率低於：

//either this 

router.redirect('/route1', '/route2'); 

//or regular koa redirect 

router.all('/route1', function *() { 
    this.redirect('/route2'); 
});
