Get Franchise Details using Franchise code or name Get NAICS details using NAICS code or Industry description "`with` statement support for `rate_limit`."Įvent.wait() # Wait for queue watcher to wake us.

This will serialize and delay requests from multiple workers for resource """Delay use of `resource` until after `delay` seconds have passed. ![]() from contextlib import contextmanagerĭef rate_limit(resource, delay, _queues=): This code assumes you're going to use gevent and monkey patch. In your case, I would do: def worker():Īssuming you have multiple domains you're culling from, I would setup a dictionary mapping (domain, delay) so you don't hit your rate limits. Just looking at this code I can tell it's 3am. It just looks like it is when I look at the console output. Plus, I don't know if it's actually working as advertised. Maybe the poolmanager could be augmented instead?Īlso, I wouldn't put this code in production - the 'q' list never gets trimmed and would eventually get pretty big. I wish there was a more elegant solution, but so far I can't find one. Rs = (rg.get(u, hooks=hook_dict) for u in urls) You can use grequests.imap() to watch this interactively import time class AsyncRequest(object):ĭef _init_(self, method, url, **kwargs): Here's a super hacky work-around to at least prove it's possible - I modified grequests to keep a list of the time when a request was issued and sleep the creation of the AsyncRequest until the requests per second were below the maximum. The only hook that seems to be around is for responses. With BaseThrottler(name='base-throttler', reqs_over_time=(15, 60)) as bt:īoth solutions can be implemented without the usage of the with statement:īt = BaseThrottler(name='base-throttler', delay=1.5)ĭoesn't look like there's any simple mechanism for handling this build in to the requests or grequests code. Where the function multi_submit returns a list of ThrottledRequest (see doc: link at the end).Īlternatively you can achieve the same by specifying the number or requests to send in a fixed amount of time (e.g. Throttled_requests = bt.multi_submit(reqs) With BaseThrottler(name='base-throttler', delay=1.5) as bt: Request = requests.Request(method='GET', url='') You can set both a fixed amount of delay between each request or set a number of requests to send in a fixed amount of seconds (which is basically the same thing):įrom requests_throttler import BaseThrottler Take a look at this for automatic requests throttling: Grequests.map(unsent_requests, size=_CONCURRENT_LIMIT_) Session=requests_session) for url in urls) Requests_session.mount(' requests_adapter) Setup: requests_adapter = adapter.MyHttpAdapter(īurst_window=datetime.timedelta(seconds=5), Verify=verify, cert=cert, proxies=proxies) Response = super(MyHttpAdapter, self).send(request, stream=stream, timeout=timeout, Gevent.sleep(wait_time.total_seconds(), ref=True) Self.total_window = burst_window + wait_window Object used for throttling: DEFAULT_BURST_WINDOW = datetime.timedelta(seconds=5)ĭEFAULT_WAIT_WINDOW = datetime.timedelta(seconds=15)ĭef _init_(self, max_hits, burst_window, wait_window): In my case I ended up with the code below. By creating our own adapter we can intercept requests and rate-limit them in way we find best for our application. Session objects on the other hand can have HTTP adapters mounted that are used when making requests. Every request object used with GRequests can take a session object as a parameter when created. Going to answer my own question since I had to figure this by myself and there seems to be very little info on this going around. ![]()
