Problem writing to href.json #14

Closed mathouthouthou closed 10 months ago

mathouthouthou commented 2 years ago

Hello I have been tryting to set up your bot but I keep having an issue when writing on the href.json file.

First I was getting a 405 status code on the results page on every crawl. I fixed this by randomizing the scrapy user agent as they mention here: https://stackoverflow.com/questions/67401114/how-can-i-use-random-useragent-everytitme-when-i-send-resquest

Now I get a 200 on that request. However I don't see anything written on the href.json file. This is the full trace of one iteration of the scraper:

Everytime I see an empty array on the scrapped results. Do you know what might be the issue?

Thank you

As you can see this project was developed several years ago, so if immobilienscout24 implemented some counter measures against bots, this could be the result. You may try wg-gesuchet.de.

If you really want to use it on immobilienscout24, you could try start scrapy alone in interactive mode and try to scrape the website you want to dig and see what returns. Just follow scrapy's introductions for beginners on how to use it. https://docs.scrapy.org/en/latest/intro/tutorial.html

@mathouthouthou did you manage to run the script correctly? I'm stuck at the same part

That's a pity. I found this project here https://github.com/orangecoding/fredy, which works like a charm with scrapingant and immoscout24. But it only sends new flats based on search criterias to a telegram bot
