FR: Support CAPTCHA library

[leonahliang90]

Describe the new feature or change to an existing feature you'd like to see

Hi @kristoferbaxter , in order to deal with Crawlers as we stated in #19580 , we would need to include some js library provided by the security team. Is there a way that we can import third js library into AMP page please ?

Describe alternatives you've considered

None

Additional context

@leonalicious depends, would the script be able to run and do its thing inside a web worker? we are not planning to allow 3P JS run in the same context as the AMP page, but rather sandboxed in a worker and communicating with the page through WorkerDom, which is exposed as amp-script.

thank you for the prompt solution, sounds legit, please spare me some time to double confirm this with our security team and I will get back to you. But regard the amp-script, if i remember it correctly it should be rolling out somewhere at the Q1 of 2019 right ?

This issue doesn't have a category which makes it harder for us to keep track of it. @choumx Please add an appropriate category.

@leonalicious Which browser APIs does this robot-detection script depend on? amp-script is based on worker-dom, which only supports a subset of available APIs.

Would putting the script in an amp-iframe work? We also have a new component for a similar feature in amp-recaptcha.

[leonahliang90]

Based on what I can tell from what we are missing is navigator.

amp-iframe is something async and I personally think it will not work, maybe worth to give a try

[dreamofabear]

Cool, let us know if amp-iframe doesn't work!

Hello!

What is the status of this? Can I close this in favor of consolidating all reCAPCTHA issues into #2273 ? Or is this not realated to amp-recaptcha-input?

Thank you! 😄

[torch2424]

Closing this in favor of #2273 . Please feel free to comment to get this re-opened if this does not support your use case. Thanks! 😄

Hello,

Sorry to reply on an old issue, but in case anyone gets here from a search engine, just want to say this was implemented in #2273 .

See my comment here for getting started: #2273 (comment)

Thanks! 😄
