// 第一个middleware是记录URL以及页面执行时间：

app.use(async (ctx, next) => {
    console.log(`Process ${ctx.request.method} ${ctx.request.url}...`);
    var
        start = new Date().getTime(),
        execTime;

    execTime = new Date().getTime() - start;
    ctx.response.set('X-Response-Time', `${execTime}ms`);
});
// 第二个middleware处理静态文件：

let staticFiles = require('./static-files');
app.use(staticFiles('/static/', __dirname + '/static'));
app.use(staticFiles('/dist/', __dirname + '/dist'));

// 第三个middleware解析POST请求：

app.use(bodyParser());
// 第四个middleware负责给ctx加上render()来使用Nunjucks：

render(app, {
  root: path.join(__dirname, 'view') ,    //挂在render  设置模板配置项
  extname: '.html',
});
// 最后一个middleware处理URL路由：

app.use(controller());
router.use('/jstreeapi',jstreeapi)
router.use('/user',user)
app.use(router.routes()).use(router.allowedMethods())


















// app.use(async function (ctx) {
//   const users = [{ name: 'Dead Horse' }, { name: 'Jack' }, { name: 'Tom' }];
//   await ctx.render('index', {   // 渲染content模板
//     users
//   });
// });
