idea2app-Lark-R2

This Cloudflare worker uploads images synchronously from Lark base to R2 object storage. To utilize this functionality, you need to set up a Lark base workflow which sends an HTTP request to the worker. Subsequently, the worker retrieves the image from Lark and transfers it to R2.

Preset

Cloudflare authentication

You'll need to configure Wrangler using GitHub's Secrets feature - go to "Settings -> Secrets" and add your Cloudflare API token (for help finding this, see the Workers documentation). Your API token is encrypted by GitHub, and the action won't print it into logs, so it should be safe!

Lark config

1. Create an workflow

2. Custom trigger Select the field where the image is located, use the image modification as a trigger condition

3. Send an HTTP request Your HTTP request should resemble the following: POST https://BUCKET_BASE_URL/lark?file_token=REDACTED&name=hello.png&type=image%2Fpng There for, you are required to include the file_token, name and type fields in your query parameters
