Question

我正在寻找一种方法让所有请求在进入路由之前进入函数foo()。

这样我就可以在做真正的工作之前阅读request.environ。

我正在尝试这样做，以便我不重复代码，但无法在 BottlyPy 中找到办法做这样的事情......

我的设置是：nginx - ＆gt; uwsgi - ＆gt; bottlepy。

这就是plugins的用途。

以下是一个例子：

import bottle
from bottle import request, response

def foo(callback):
    def wrapper(*args, **kwargs):
        # before view function execution
        print(request.environ)  # do whatever you want

        body = callback(*args, **kwargs)  # this line basically means "call the view normally"

        # after view function execution
        response.headers['X-Foo'] = 'Bar'  # you don't need this, just an example

        return body  # another 'mandatory' line: return what the view returned (you can change it too)
    return wrapper

bottle.install(foo)

BottlePy预请求处理
