[英]Custom Decorators in Tornado
I'm facing an error while trying to make a custom tornado decorator. 尝试制作自定义龙卷风装饰器时遇到错误。
TypeError: post() missing 1 required positional argument: 'self'
The sample code is: 示例代码是:
def decorate( function_name ):
# Do something
function_name()
# Do something
class MainHandler( tornado.web.RequestHandler ):
@decorate
def post( self ):
# Do whatever
How do I pass the context of self
to the decorator ? 如何将
self
的上下文传递给装饰器?
It seems you're not passing the arguments from the decorator to the decorated method. 似乎您没有将参数从装饰器传递给装饰的方法。
Here's how your decorator should look like: 这是您的装饰器的外观:
def decorate(func):
def wrapper(*args, **kwargs):
# pass the received arguments to
# the decorated function
return func(*args, **kwargs)
return wrapper
