if isinstance(r, dict):
    template = r.get('__template__')
    if template is None:
        resp = web.Response(body=json.dumps(r, ensure_ascii=False, default=lambda o: o.__dict__).encode('utf-8'))
        resp.content_type = 'application/json;charset=utf-8'
        return resp
    else:
        resp = web.Response(body=app['__templating__'].get_template(template).render(**r).encode('utf-8'))
        resp.content_type = 'text/html;charset=utf-8'
        return resp

app['__templating__']是哪里来的啊，没明白啊

app初始化init_jinja2时进行依赖注入，详情请看第39行。

需要注意r.get('__template__')和app['__templating__']是两个完全不同的东西

async def init(loop):
    await orm.create_pool(loop=loop, host='127.0.0.1', port=3306, user='www', password='www', db='awesome')
    app = web.Application(loop=loop, middlewares=[
        logger_factory, response_factory
    ])
    init_jinja2(app, filters=dict(datetime=datetime_filter))

init_jinja2不是在response_factory之后才调用的吗

@风飞浅停 我明白了，middlewares里的函数，是在调用了add_route之后才会调用到的，是吧?

你查看主页的流程图就明白了，注册中间件之后，每个request请求都会调用到
