    Everyone loves the idea of scraping, no one likes maintaining scrapers that break once a week because the CSS or HTML changed.

      spite can be a great motivator, though

        This one. One of the best motivators. Sense of satisfaction when you get it working and you feel unstoppable (until the next subtle changes happens anyway)

        I successfully scraped millions of Amazon product listings simply by routing through TOR and cycling the exit node every 10 seconds.

      What’s wrong with parsing HTML with regex?

      source
      • indepndnt@lemmy.world ⁨2⁩ ⁨years⁩ ago

        In short, it’s the wrong tool for the job.

        In practice, if your target is very limited and consistent, it’s probably fine. But as a general statement about someone’s behavior, it really sounds like someone is wasting a lot of time and regularly getting sub-par results.

  • ViscloReader@lemmy.world ⁨2⁩ ⁨years⁩ ago

    Just a heads up for companies thinking it’s wrong to scrap: if you don’t want info to be scraped, don’t put it on the internet.

    The sad part is that scrapping is often easier then using the api.

    source
    • Anonymousllama@lemmy.world ⁨2⁩ ⁨years⁩ ago

      Much less beholden to arbitrary rules also. Way too many times companies will just up and lift their API access or push through restrictions. No ty, I’ll just access it myself then

        API starter kit

        • Outdated and unsupported and hasn’t been replaced yet but is the standard way to use the service.
        • Lots of authorization tokens.
        • The example in the docs doesn’t work (if there is one).
        • You have no idea where the online tutorial got the information because it doesn’t have links to resources and the docs have barely anything even though its giant.
        • Uses asynchronous programming to make it faster but its still much much slower then scrapping without asynchronous programming.

        When a customer needs a part replaced, they send in shipping data. This data has to be entered into 3-4 different web forms and an email. This allows me to automate it all from a single form that has built in error checking so human mistakes are limited.

        Company could probably automate this all in the backend but they won’t :shrug:

      Websites and services create APIs for programmers to use them. So Spotify has code that let’s you build a program that can use its features. But you need a token they give you after you sign up. The token can be revoked and used to monitor how much of their service you’re using. That way they can restrict if its too much.

      Scraping is raw dogging the web slut you met at the cougar ranch who went home with you because you reminded her of her dog

    • DarkSpectrum@lemmy.world ⁨2⁩ ⁨years⁩ ago

      ‘Scraping’ is the process of anonymously and programmatically collecting data from a webpage(s), often without the website’s permission and only limited to the content made publicly available. This is I contrast to using an API provided by the database owner which is limited by tokens, access volume, available end points etc.

      Imagine an investment firm looking at a property market. They need data like price trends in the surrounding area.

      Real estate API is expensive, scraping is free. By hiring an employee the can save money.

    • Theharpyeagle@lemmy.world ⁨2⁩ ⁨years⁩ ago

      There’s a ton of money to be made from scraping, consolidating, and organizing publicly accessible data. A company I worked for did it with health insurance policy data because every insurance company has a different website with a different data format and data that updates every day. People will pay da big bux for someone to wrap all that messiness into a neat, consistent package.

      Right now, gathering machine learning data is hot, cause you need a lot of it to train a model. Companies may specialize in getting, say, social media posts from all kinds of sites and putting them together in a consistent format.

    • lutillian@sh.itjust.works ⁨2⁩ ⁨years⁩ ago

      Start looking into selenium, probably in Python. It’s one of the easier to understand forms of scraping. It’s mainly used to web testing, though you can definitely use it for less… nice purposes.

      Step one will be learning to code in any language. Step two is using a library to help with it and don’t use regex like the meme says haha. HtmlAgilityPack has always been there for me.
