​App cannot generate a card for a link about affine

[darkskygit]

i have updated the behavior of link preview api, now the website you provided is ready for preview

[fundon]

We can try to adjust the header first, and reuse user-agent via web(extract from post-link-preview request).

@darkskygit pls take a look

The firewall deployed by this website blocked our preview request.
We will adjust the behaviour of preview request later, but this may not have much effect.
We recommend that you contact the website to allow our preview API request.

I'm curious to know how Notion is capable of handling this correctly. Maybe the user agent request header is being spoofed? It is not realistic to request websites to make this change.

They used a paid service, and the paid service uses AWS machines. Since the website you mentioned is also provided by AWS, I can assume that the service may has the right to bypass AWS WAF.

I know that Appflowy integrates third-party services (e.g. OpenAI), but requires the user to provide their own token to use it. Otherwise, it remains inactive. Could something similar be done for iframely? They seem to offer a good free tier that I could take advantage of.

@fundon @fourdim what do you think about this? i think integrate into worker is more insensitive, or do you think it’s better to be integrated directly by bs?

I would like to have a fallback button so that if the retrieval fails using a worker, the user can click on the fallback button to initiate a request from the client to retrieve the og meta.
Globally, user can also set to request resources directly from client.

Is it possible to use electron backend as a proxy?
