const Koa = require('koa');

const app = new Koa();

app.use(
    async function (ctx, next) {
        try {
            await next();
        } catch (e) {
            console.log('catch error:', e.toString())
        }
    }
)

app.use(
    function (ctx, next) {
        console.log('m1');
        return next()
    }
)

app.use(
    function (ctx, next) {
        console.log('m2');
        return next().then(next)
    }
)
