QUESTION

Scrapy Timeouts and Twisted.Internet.Error

Asked 2019-Jan-21 at 12:23

Running Scrapy with Proxies but there are times when the crawl runs into the errors below at the end of the run and causes the crawl finish time to be delayed by 10+ seconds. How can I make it so that if Scrapy runs into these errors at any point, it is ignored/passed completely and immediately when detected so that it doesn't waste time stalling the entire crawler?

RETRY_ENABLED = False (Set in settings.py already.)

List of urls in request. Many proxies set to https:// rather than http, wanted to mention incase, although for almost all cases https works, so I doubt it is strictly about https vs http being set.

But still get:

That is already the case. The proxies are either causing the error after a few seconds instead of instantly, or directly timing out.

If you are not willing to wait, you could consider decreasing the DOWNLOAD_TIMEOUT setting, but responses that used to take long but work may start timing out.

A better approach may be to switch to better proxies, or consider a smart proxy (e.g. Crawlera).

QUESTION

Get proxy response in middleware

Asked 2019-Jan-14 at 08:10

i have the following problem with scrapy in my middleware:

I do a request to a site with https and also use a proxy. When defining a middleware and using process_response in it, response.headers does only have the headers from the website. Is there any way to get the headers from the CONNECT request the proxy tunnel establish? The proxy we are using is adding some informations as headers in this response, we want to use it in the middleware. I found out that in TunnelingTCP4ClientEndpoint.processProxyResponse the parameter rcvd_bytes has all infos i need. I didn't find a way to get the rcvd_bytes in my middleware.

Also i found a similiar (same) issue from a year ago which is not solved: Not receiving headers Scrapy ProxyMesh

Here is the example from the proxy website:

For HTTPS the IP is in the CONNECT response header x-hola-ip Example for Proxy Peer IP of 5.6.7.8:

I saw in #3329 that someone from Scrapinghub said it is unlikely they will add that feature, and recommended creating a custom subclass to get the behavior that you wanted. So, with that in mind:

I believe after you create the subclass, you can tell scrapy to use it by setting the http and https keys in DOWNLOAD_HANDLERS to point to your subclass.

Bear in mind that I don't have a local http proxy that sends extra headers to test, so this is just a "napkin sketch" of what I think needs to happen:
