[英]How to log redirects in Pyramid?
I'm trying to set it up so that my Pyramid app logs a message whenever it does a redirect - eg When one of my views raises HTTPFound
. 我正在尝试对其进行设置,以使我的Pyramid应用程序
HTTPFound
重定向时(例如,当我的某个视图引发HTTPFound
时)记录一条消息。
Creating a custom subclass of HTTPFound
worked but it sucks to have to make sure that class is used everywhere in the app. 创建
HTTPFound
的自定义子类是HTTPFound
但是必须确保该类在应用程序中的任何地方都使用很HTTPFound
。
I then had the idea of creating a custom exception view with context=HTTPFound
but that view doesn't seem to get called. 然后,我想到了使用
context=HTTPFound
创建自定义异常视图的想法,但是该视图似乎没有被调用。
Is there a standard way to set up special handling for a redirect that is global to the app? 是否有一种标准方法可以为应用程序全局重定向设置特殊处理?
To log out redirects you would just have a tween that checks the return status, something like: 要注销重定向,您将只有一个补间可以检查返回状态,例如:
from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.httpexceptions import HTTPFound
def hello1(request):
raise HTTPFound(request.route_url('hello2'))
def hello2(request):
return {'boom': 'shaka'}
def redirect_logger(handler, registry):
def redirect_handler(request):
response = handler(request)
if response.status_int == 302:
print("OMGZ ITS NOT GOING WHERE YOU THINK")
return response
return redirect_handler
def main():
config = Configurator()
config.add_route('hello1', '/', view=hello1)
config.add_route('hello2', '/hi', view=hello2, renderer='json')
config.add_tween('__main__.redirect_logger')
app = config.make_wsgi_app()
return app
if __name__ == '__main__':
app = main()
server = make_server('0.0.0.0', 8080, app)
print("http://0.0.0.0:8080")
server.serve_forever()
