And how would I make sure it was my worker

.gwapesOP•11/20/23, 12:09 PM

Also, is it not very optimal to just have an authorisation header?

Hello, I’m Allie!•11/20/23, 12:10 PM

You could use a Tunnel, and then not expose the server at all

..gwapes Also, is it not very optimal to just have an authorisation header?

Hello, I’m Allie!•11/20/23, 12:11 PM

You can, but with this method, you literally can't hit the origin at all(barring any issues on CF's side), while with the Auth Header method, a bad actor can still hammer your DB with requests, even if they aren't authorized

.gwapesOP•11/20/23, 12:12 PM

I’m a bit lost with the last part there. I only actually make the db update if the auth headers value is that “random string”, so it won’t do anything if it’s not right

Hello, I’m Allie!•11/20/23, 12:13 PM

Yes, but in this case, if I want to take your DB out of commision, I can just send random requests to your server. The changes won't be able to be applied, but because your server is busy handling my requests, it won't have time to handle your valid changes

.gwapesOP•11/20/23, 12:13 PM

But that would be an express like thing, right? Rather then a db thing. Because it’s just busy not doing anything but handling the wrong requests

.gwapesOP•11/20/23, 12:14 PM

So it would be better to return wrong requests from my cf worker where everything goes through anyway?

Hello, I’m Allie!•11/20/23, 12:14 PM

Yes, because no matter how beefy your server is, Workers will be able to burst to much higher capacity than Express

Just to confirm, I can still use the auth header method, right? Just instead using the worker to say yes or no

Yeah, you could

Is there an npm package or something similar for how to type the context param here

export default {
  async fetch(request, env, context) {
    // Proxy to origin on unhandled/uncaught exceptions
    context.passThroughOnException();
    throw new Error('Oops');
  },
};

export default {
  async fetch(request, env, context) {
    // Proxy to origin on unhandled/uncaught exceptions
    context.passThroughOnException();
    throw new Error('Oops');
  },
};

mooon•11/20/23, 9:45 PM

it works fine

mooon•11/20/23, 9:45 PM

kian•11/20/23, 9:49 PM

Try adding https://github.com/rustwasm/console_error_panic_hook

mooon•11/20/23, 9:55 PM

Please do not post your question in multiple channels per the rules at #

welcome-and-rules. It creates confusion for people trying to help you and doesn't get your issue or question solved any faster.

Hello guys, is it possible to create a custom access link to a specific file via cloudflare cdn api? I have been looking through the documentation all day but I don t seem to find my answer. A little direction would be greatly appreciated!

Hello, I’m Allie!•11/21/23, 5:38 PM

You would have to expose that file somehow. Cloudflare doesn’t provide any ootb file lockers

Hello, I’m Allie!•11/21/23, 5:38 PM

As in, you could build one with R2 and then slap Access on top

ChecDePost•11/21/23, 5:42 PM

ChecDePost•11/21/23, 6:10 PM

what about token based file access? would that be a possibility?

Hello, I’m Allie!•11/21/23, 6:12 PM

It don't see why not, though again, you would have to build it yourself, or find a project that does it for you

And how would I make sure it was my worker
