we're in web 3.0 now, apis and data access are a thing of the past. so scraping it is!

[-] einkorn@feddit.org 73 points 3 months ago* (last edited 3 months ago)

Guess who recently asked a company if he could get access to the API they use to load stuff in their frontend from their backend and got told "Nope and btw scraping is against our TOS"?

Well, if you won't give it to me the info that you provide anyway the easy way, I can still take it the hard way. 🤷‍♂️

Maybe you should just try being lucky. I found a critical security vulnerability while working on my scraping project. I told them, they paid me and gave me written permission to scrape.

[-] einkorn@feddit.org 26 points 3 months ago

You are braver than I am because here in Germany usually people get sued for reporting security vulnerabilities.

[-] MonkderVierte@lemmy.zip 15 points 3 months ago

Yep, don't do that if you live in a Internet ist Neuland country.

[-] victorz@lemmy.world 7 points 3 months ago

tf? They should offer you a job if anything.

[-] einkorn@feddit.org 10 points 3 months ago

That is if you'd live in a place with an open attitude toward new technologies.

I know a guy who did exactly that and got sued. The security failure he reported even was a Straftatbestand committed by the company and so he won the process. German companies really love shooting themselves in the foot.

[-] bless@lemmy.ml 2 points 3 months ago* (last edited 3 months ago)

Over here, not just sued, but sued for extortion because they had the audacity to ask for bug bounty. Ok then, if I ever find a security hole that exposes sensitive data, filing a gdpr report it is

"by using this site you agree to..."

I'm not using your site. And I agree to nothing. Now, go GET for me.

Local data hoarder who looks down on calls outside the network as obscenities. (Entire collection scraped more aggressively than tech bros training an AI model)

Just remeber that the captcha flood is because AI companies do rogue scraping. Be nice especially to little private sites.

[-] explodicle@sh.itjust.works 10 points 3 months ago

They should just charge a tiny fee, or return Error 402 Payment Required.

[-] piccolo@sh.itjust.works 9 points 3 months ago

Better yet, return bogus pages created by ai to poison the data.

[-] explodicle@sh.itjust.works 3 points 3 months ago

Instead of CAPTCHAs?

parses HTML with regex

shudders

[-] KairuByte@lemmy.dbzer0.com 75 points 3 months ago

You can't parse [X]HTML with regex. Because HTML can't be parsed by regex. Regex is not a tool that can be used to correctly parse HTML. As I have answered in HTML-and-regex questions here so many times before, the use of regex will not allow you to consume HTML. Regular expressions are a tool that is insufficiently sophisticated to understand the constructs employed by HTML. HTML is not a regular language and hence cannot be parsed by regular expressions. Regex queries are not equipped to break down HTML into its meaningful parts. so many times but it is not getting to me. Even enhanced irregular regular expressions as used by Perl are not up to the task of parsing HTML. You will never make me crack. HTML is a language of sufficient complexity that it cannot be parsed by regular expressions. Even Jon Skeet cannot parse HTML using regular expressions. Every time you attempt to parse HTML with regular expressions, the unholy child weeps the blood of virgins, and Russian hackers pwn your webapp. Parsing HTML with regex summons tainted souls into the realm of the living. HTML and regex go together like love, marriage, and ritual infanticide. The <center> cannot hold it is too late. The force of regex and HTML together in the same conceptual space will destroy your mind like so much watery putty. If you parse HTML with regex you are giving in to Them and their blasphemous ways which doom us all to inhuman toil for the One whose Name cannot be expressed in the Basic Multilingual Plane, he comes. HTML-plus-regexp will liquify the n​erves of the sentient whilst you observe, your psyche withering in the onslaught of horror. Rege̿̔̉x-based HTML parsers are the cancer that is killing StackOverflow it is too late it is too late we cannot be saved the transgression of a chi͡ld ensures regex will consume all living tissue (except for HTML which it cannot, as previously prophesied) dear lord help us how can anyone survive this scourge using regex to parse HTML has doomed humanity to an eternity of dread torture and security holes using regex as a tool to process HTML establishes a breach between this world and the dread realm of c͒ͪo͛ͫrrupt entities (like SGML entities, but more corrupt) a mere glimpse of the world of reg​ex parsers for HTML will ins​tantly transport a programmer's consciousness into a world of ceaseless screaming, he comes~~, the pestilent sl~~ithy regex-infection wil​l devour your HT​ML parser, application and existence for all time like Visual Basic only worse he comes he comes do not fi​ght he com̡e̶s, ̕h̵i​s un̨ho͞ly radiańcé destro҉ying all enli̍̈́̂̈́ghtenment, HTML tags lea͠ki̧n͘g fr̶ǫm ̡yo​͟ur eye͢s̸ ̛l̕ik͏e liq​uid pain, the song of re̸gular exp​re~~ssion parsing ~~will exti​nguish the voices of mor​tal man from the sp​here I can see it can you see ̲͚̖͔̙î̩́t̲͎̩̱͔́̋̀ it is beautiful t​he final snuffing of the lie​s of Man ALL IS LOŚ͖̩͇̗̪̏̈́T A*LL I​S LOST the pon̷y he comes he c̶̮om~~es he co~~**~~me~~s the* ich​or permeates all MY FAC*E MY FACE ᵒh god no NO NOO̼O​O NΘ stop the an​*̶͑̾̾​̅ͫ͏̙̤g͇̫͛͆̾ͫ̑͆l͖͉̗̩̳̟̍ͫͥͨe̠̅s ͎a̧͈͖r̽̾̈́͒͑en​ot rè̑ͧ̌aͨl̘̝̙̃ͤ͂̾̆ ZA̡͊͠͝LGΌ ISͮ̂҉̯͈͕̹̘̱ TO͇̹̺ͅƝ̴ȳ̳ TH̘Ë͖́̉ ͠P̯͍̭O̚​N̐Y̡ H̸̡̪̯ͨ͊̽̅̾̎Ȩ̬̩̾͛ͪ̈́̀́͘ ̶̧̨̱̹̭̯ͧ̾ͬC̷̙̲̝͖ͭ̏ͥͮ͟Oͮ͏̮̪̝͍M̲̖͊̒ͪͩͬ̚̚͜Ȇ̴̟̟͙̞ͩ͌͝*S̨̥̫͎̭ͯ̿̔̀ͅ

Have you tried using an XML parser instead?

I got a bot on lemmy that scrapes espn for sports/football updates using regex to retrieve the JSON that is embedded in the html file, it works perfectly so far 🤷‍♂️

[-] MonkderVierte@lemmy.zip 3 points 3 months ago

Delete all line breaks, add one each <, get the data you want per line and you're good.

Of course, only for targeted data extraction. ...which should be the default in any parser, really.

First time I'm seeing this, and I have to say I admire their dedication to the joke.

Zombo.com is a single-serving site created in 1999...

...

The site was initially a Flash animation, but as of 5 January 2021, it switched to HTML5 due to the discontinuation of Adobe Flash Player.

Hey, you guys got any cool tips for website scraping?

[-] luciole@beehaw.org 36 points 3 months ago

They're gonna tell not to parse HTML with regular expressions. Heed this warning, and do it anyways.

What exactly are y'all scraping?

[-] chaospatterns@lemmy.world 8 points 3 months ago

I scrape my own bank and financial aggregator to have a self hosted financial tool. I scrape my health insurance to pull in data to track for my HSA. I scrape Strava to build my own health reports.

Ha, this reminds me of implementing “API” access in the shipping world for companies that only ship a 90s-style web portal.
