Question

I’ve been playing with tweepy for a while, but I keep having rate-limiting issues, getting 429 errors. I know you can set the headers on individual calls like

api.get_user('twitter', headers={'User-Agent': 'MyUserAgent'})

but is there a way to set the header in one place and not have to do it on every api call?

Answer 1

Hacky way:

import functools
class NewAPI(object):
    def __init__(self, api):
        self.api = api
    def __getattr__(self, key):
        call = getattr(self.api, key)
        @functools.wraps(call)
        def wrapped_call(*args, **kwargs):
            headers = kwargs.pop('headers', {})
            headers['User-Agent'] = 'MyUserAgent' # or make this a class variable/instance variable
            kwargs['headers'] = headers
            return call(*args, **kwargs)
        return wrapped_call

api = NewAPI(api)
print(api.get_user('twitter'))

Disclaimer: untested as I don’t have tweepy.
