feat(store): specify links to navigate to between product searches #1542

neatchee · 2020-12-29T09:01:42Z

...to reduce likelihood of bot detection/captcha

Description

Fixes #1504
When querying a store, if deterrentLinks has been defined, pick one at random and navigate there then wait 3 seconds. This should help reduce the likelihood of being sent to a captcha on subsequent page loads from the same store.
Defined in store model as 'captchaDeterrent' with parameters:
hardLinks string[]
searchUrl string
searchTerms string[]

Testing

Add the following to amazon.ts (already added in pr)

	captchaDeterrent: {
		hardLinks: ['https://www.amazon.com/Amazon-Video/b/?ie=UTF8&node=2858778011&ref_=nav_cs_prime_video',
			'https://www.amazon.com/alm/storefront?almBrandId=VUZHIFdob2xlIEZvb2Rz&ref_=nav_cs_whole_foods_in_region',
			'https://www.amazon.com/gp/goldbox?ref_=nav_cs_gb'],
		searchUrl: 'https://www.amazon.com/s?k=%%s&i=todays-deals&ref=nb_sb_noss_2',
		searchTerms: ['goober', 'dungeons+and+dragons']
	},

set HEADLESS=false in dotenv
npm start run

New dependencies

None

Hey @neatchee it is only amazon US?
Please make it for all Amazon Stores 👍

This is just the framework and one store setup for it. There will be a lot of work required to add the deterrent links for all the different stores that need it.

I merged your changes into my cloned main locally and ran it for a a while. After an hour or so, Amazon captcha started coming up and it did not go away.

p.s. I did not do headless=false, I used true, what is the impact of that?

Headless=true is the default, so it does nothing.

This change only includes a very basic list of links to use for Amazon. Even with a comprehensive list, this change will not protect 100% against captcha. It will still depend on how frequently you query Amazon pages. This is meant to reduce the likelihood by some reasonable amount, not prevent captchas entirely.

Do you think more links would help? Also, I have tweaked the delay between requests to be longer but I guess that doesn't matter to Amazon, their 'cache' of lookups maybe be a hashmap with no expiration on the keys

I'll look at this in length tomorrow (probably). Thank you @neatchee!

Maybe I just don't understand git but...this was merged into main but isn't showing up in main's commit history???

I don't think so! Perhaps misread?

jef · 2021-01-10T18:06:07Z

I wonder for searchTerms if we have a master list of random words rather per store? What do you think of that?

Cool idea though, I like it!

neatchee · 2021-01-10T19:13:23Z

I like the ability to go per-store incase they get wise to searches that return no results, but I'd totally be happy with a default list to use if one isn't specified for the store

Hmm... I guess there are only so many retailers that carry generic products. Perhaps this is fine. No worries! We can stick with this.

Overall looks good, just a suggestion and comment.

Thanks @neatchee!

src/config.ts

jef · 2021-01-10T20:39:01Z

src/store/lookup.ts

+			setTimeout(() => {
+				// Do nothing
+			}, 3000);


How come we want this 3 second timeout?

This is basically an arbitrary "wait after page load so we don't look as bot-like". I was being cautious about us hitting a search page and then immediately bouncing to another page as soon as the search results are loaded. I wanted to at least KINDA look like someone actually viewed the search results hehe.

That makes sense to me :)

It seems to work. Tried it against german amazon pages.
Here is my amazon-de.ts - captchaDeterrent part:

captchaDeterrent: { hardLinks: [ 'https://www.amazon.de/Amazon-Video/b?ie=UTF8&node=3010075031', 'https://www.amazon.de/dp/B00NTQ6K7E?ref_=nav_em_adbl_nav_sl_link1_0_2_11_2', 'https://www.amazon.de/gp/goldbox?ref_=nav_cs_de' ], searchTerms: ['hirschhausen', 'matrix', 'tefal', 'playstation', 'fifa', 'xbox'], searchUrl: 'https://www.amazon.de/s?k=%%s&i=todays-deals&ref=nb_sb_noss_2' },

What happens if you have headless true? I've tested it with headless and didn't have any issue.

didn't have any issue.

EDIT: I've changed some network routing and added some searchTerms and hardLinks, and it does work with headless=true too. (Probably some kind of side effect caused by older bot checks). I will monitor it a little longer.

OLD Comment: The CAPTCHA notification reoccur if HEADLESS is set to true. If HEADLESS is set to false, no CAPTCHA notification occurs.

jontaru · 2021-01-14T16:11:05Z

Testing this and I am still getting captcha with headlless false for amazon-ca, was it merged into the main branch?

kangelovski · 2021-01-14T16:42:30Z

It's not merged yet. You would need to modify four files by yourself. Instead of amazon.ts, you would need to modify the amazon-ca.ts file.

neatchee · 2021-01-14T18:05:37Z

Oh, yeah, this won't completely defend against captcha, especially if your IP has already been flagged.

I only received CAPTCHAs again. If I switch to non-headless and back to headless again, the CAPTCHAs disappear. I can imagine the changed viewport of the browser triggered the bot-recognation back to "human user"... Maybe we can randomize the viewport parameters too? (I would recommend, that viewport-size is getting changed between each random 60 seconds / 20 minutes)

neatchee · 2021-01-15T09:15:54Z

As I mentioned, this alone won't stop captcha. There are a larger number of factors that contribute to whether or not you get sent to a captcha. This is just one tool in the toolbox and does not guarantee that you won't see a captcha. The most important thing with captcha is request frequency. The fewer stores, the fewer models/products, the more likely you are to get a captcha.

Please don't get me wrong. I like that tool! I don't criticize the occurence of captcha in my test. I'm just trying to support you with my insights.
