koa-router 404 on node.js

platform node: v-4.4.5 koa: v-2.0.0 koa-router: v-7.0.0

here is my code

///<reference path="../typings/tsd.d.ts" />
//导入koa，和koa 1.x不同，在koa2中，我们导入的是一个class，因此用大写的Koa表示:
var Koa = require('koa');

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


// 创建一个Koa对象表示web app本身:
var app = new Koa();

// parse request body:


//add url-route:
router.get('/hello/:name', (ctx, next) => {
    var name = ctx.params.name;
    ctx.response.body =`<h1>Hello, ${name}!</h1>`;
});

router.get('/',  function *(ctx, next) {
    ctx.response.body = '<h1>Index</h1>';
});

router.all('/login', function *() {
  this.redirect('/');
  this.status = 301;
});

app.use(function (ctx,next){
  this.body = `Invalid URL!!!${ctx.request.method} ${ctx.request.url}`;
  ctx.response.type = 'text/html';
  ctx.response.body = this.body;
});

app.use(router.routes())
.use(router.allowedMethods());
// 在端口3000监听:
app.listen(3000);
console.log('app started at port 3000...');

when I Brower http://localhost:3000/,output 'Invalid URL!!!'. tell me why can't match '/' router ? thank you!

you can use '*' to match urls like 404 or invalid links:

router.all('*', function(ctx, next) {
  //
});

upgrade your node version to 7.6.0. koa2 work on >=7.6.0 and code like

Koa=require('koa')
    var app = new Koa();
    router = require('koa-router')()
    // parse request body:


    //add url-route:
    router.get('/hello/:name', (ctx, next) => {
        var name = ctx.params.name;
        ctx.response.body =`<h1>Hello, ${name}!</h1>`;
    });

    router.get('/',  function (ctx, next) {
        console.log(ctx.request);
        ctx.body = '<h1>Index</h1>';
    });

    router.all('/login', function (ctx) {
      ctx.redirect('/');
      ctx.status = 301;
    });

    app.use(function (ctx,next){
      this.body = `Invalid URL!!!${ctx.request.method} ${ctx.request.url}`;
      ctx.response.type = 'text/html';
      ctx.response.body = this.body;
      next()
    });

    app.use(router.routes())
    .use(router.allowedMethods());
    // 在端口3000监听:
    app.listen(3000);
    console.log('app started at port 3000...');
