python - tornado 框架的 context_processor

Question

tornado python框架如何实现context_processor或中间件？我想将公共(public)变量添加到 base.html 模板。无需更改所有处理程序基类。

Answer 1

可以这样做:

class MyHandler(tornado.web.RequestHandler): 
    def render(self, *args, **kwargs): 
        kwargs['my_context_variable'] = 'context' 
        return super(MyHandler, self).render(*args, **kwargs)
