How to correctly implement HTTPS communication from a browser extension?

[bytewife]

Hi! I'm wondering if you can help me (an HTTPS/browser novice) get un-stuck with an issue I've been having while using this plugin to communicate with a browser extension 😅. Decided to post this here so that others may read this as well.

I've been building a browser extension that reads Obsidian files. Sending Obsidian GET requests involving auth work in insecure mode, but only in a web-ext-opened browser and not in browsers opened normally. I'm thinking the issue is related to CORS, so I'm trying to add HTTPS. However, I am still unable to access endpoints that require auth, such as https://127.0.0.1:27124/vault/ or opening a file. I'm using this function to send the GET request. How would you go about reading files from a web browser?

Note: I added this plugin's certificate as a browser CA, but the issue remained.

It's a little bit difficult to say, but one thing you could check is that you've declared which URLs you'd like to interact with in your manifest (e.g. https://github.com/coddingtonbear/obsidian-web/blob/master/public/manifest.json#L38). You may need to remove/re-add your browser extension after changing that, too.

Ah my issue turned out to be unrelated to the HTTPS connection. If anyone wants another code reference you can check out the browser extension listed above!
