Just save your cache in room/sqlite/file and save last update date in shared preferences. Create the repository class with local and remote data sources. Fetch the data from the local data source if last update date is less than 5 minutes, otherwise fetch it from remote source.

Or you can try to use okhttp capabilities: you need cache interceptor like this:

How can I use scrapy middlewares to call a mail function?

Asked 2020-Nov-26 at 10:04

I have 15 spiders and every spider has its own content to send mail. My spiders also have their own spider_closed method which starts the mail sender but all of them same. At some point, the spider count will be 100 and I don't want to use the same functions again and again. Because of that, I try to use middlewares. I have been trying to use the spider_closed method in middlewares but it doesn't work.

It is important to run spider from scrapy crawl command so it will see whole project configuration correctly. Also, you need to make sure that custom middleware is listed in SPIDER_MIDDLEWARES dict and assigned order number. Main entry point for middleware is from_crawler method, which should receive crawler instance. Then you can write your middleware processing logic here by following rules mentioned here.

Scrapy doesn't bring back the elements

Asked 2020-Nov-22 at 11:47

The log, I suppose, shows no serious problem, but no elements are scraped. So, I guess the problem might be because of the XPath expressions. But, I double-checked them and simplify them as well as I could. Therefore, I really need help in finding the bugs here.

First of all, thanks to @ShudiptaSharma. His comment helped me in figuring out that I was trying to get the cluster config from outside of the cluster which was leading the program on my local machine (127.0.0.1) from where I am not able to access the cluster.

Further, I tried to figure out how to access the cluster from outside the cluster and found that InClusterConfig is used for running inside cluster use case, when running outside the cluster, something like the following can be used:

I'm sharing the solution I previously gave you in private, so everybody can have access to it.

First of all, since you are using fastcgi, you must use the fastcgi_cache_* directives,

QUESTION

Scrapy and invalid cookie found in request

Asked 2020-Aug-29 at 16:45

Web Scraping Needs

To scrape the title of events from the first page on eventbrite link here.

Approach

Whilst the page does not have much javascript and the page pagination is simple, grabbing the titles for every event on the page is quite easy and don't have problems with this.

However I see there's an API which I want to re-engineer the HTTP requests, for efficiency and more structured data.

Problem

I'm able to mimic the HTTP request using the requests python package, using the correct headers, cookies and parameters. Unfortunately when I use the same cookies with scrapy it seems to be complaining about three key's in the cookie dictionary that are blank 'mgrefby': '', 'ebEventToTrack': '', 'AN': '',. Despite the fact that they are blank in the HTTP request used with the request package.

It looks like they're using not value instead of the more accurate value is not None. Opening an issue is your only long-term recourse, but subclassing the cookie middleware is the short-term, non-hacky fix.

A hacky fix is to take advantage of the fact that they're not escaping the cookie value correctly when doing the '; '.join() so you can set the cookie's value to a legal cookie directive (I chose HttpOnly since you're not concerned about JS), and cookiejar appears to discard it, yielding the actual value you care about

Scraping recursively with scrapy

Asked 2020-Feb-07 at 17:37

I'm trying to create a scrapy script with the intent on gaining information on individual posts on the medium website. Now, unfortunately, it requires 3 depths of links. Each year link, and each month within that year and then each day within the months links.

I've got as far as managing to get each individual link for every year, every month in that year and every day. However I just can't seem to get scrapy to deal with the individual day pages.

I'm not entirely sure whether I'm confusing using rules and using functions with callbacks to get the links. There isn't much guidance on how to recursively deal with this type of pagination. I've tried using functions and response.follow by itself without being able to get it to run.

The parse_item function dictionary is required because several articles on the individual day pages have several different ways of classifying the title annoyingly. So i created a function to grab the title regardless of the actual XPATH needed to grab the title.

The last function get_tag is needed because on each individual article that is where the tags are to grab.

I'd appreciate any insight into how to get the last step and getting the individual links to go through the parse_item function, the shell o. I should say there are no obvious errors than I can see in the shell.

Any further information necessary just let me know.

Thanks!
