如何使用 init 参数为处理程序设置龙卷风路由？

Question

我正在构建一个龙卷风网络服务器。其中一个处理程序需要初始化参数。如何设置路由列表以便我可以传递参数值？

class ActionHandler():
    def __init__(self, p1, p2):
        self.p1 = p1
        self.p2 = p2

    async def post(self, action):
        x = self.p1 
        y = self.p2
        # ....

app = tornado.web.Application([
    ('/action', ActionHandler) # How to pass init parameters?

Answer 1

documentation notes that you should not override the __init__ method of a RequestHandler subclass. If you want to pass initial arguments to the handler, use the initialze method.

class ActionHandler():
    def initialze(self, p1, p2):
        self.p1 = p1
        self.p2 = p2

# then pass these arguments in a dict 
# when you register the route
app = tornado.web.Application([
    ('/action', ActionHandler, {'p1': 'Hello', 'p2': 'World'}),
])
