Ok, looking at it, it does appear to work if you add a

@HardlyWorkin' It appears to have worked. The binding found worker and called the method. I made a mistake in my code, but that will be quickly fixed.

Steven•5/8/24, 9:56 PM

Hi all, I have a quick questions, I currently have a Worker that is responsible for putting json's in KV that will be read from a Cloudflare pages project. The idea is to prepopulate the cache in order to get super fast pages. At the moment I created a worker that runs fine locally and can add a few thousand entries into my local wrangler state. However after deploying the worker I hit the limit of 50 subrequests. I think I can rewrite the worker to use a queue and split up the work, thus reducing the number of subrequests. But I'm wondering what the best approach is for my use case?

in wrangler.toml how do import the vars for the cloudflare worker to use from my own .env file? currently it seems cloudflare is interpreting dotenv as its own variable rather than importing the variables

ok so i set up a .dev.vars file with my env variables and then deployed the worker but i still don't see it showing up on the cloudflare dashboard, nor is my worker using it. Am i misunderstanding how it's meant to be used?

export interface Env {
    BUCKET_URL_AUTH_GENERATION_KEY: string;
    BUCKET_URL_SYMMETRIC_KEY: string;
}

export default {
    async fetch(request: Request, env: Env,): Promise<Response> {
        if (!env.BUCKET_URL_AUTH_GENERATION_KEY || !env.BUCKET_URL_SYMMETRIC_KEY) {
            return new Response("Missing required environment variables", { status: 500 });
        }

export interface Env {
    BUCKET_URL_AUTH_GENERATION_KEY: string;
    BUCKET_URL_SYMMETRIC_KEY: string;

export default {
    async fetch(request: Request, env: Env,): Promise<Response> {
        if (!env.BUCKET_URL_AUTH_GENERATION_KEY || !env.BUCKET_URL_SYMMETRIC_KEY) {
            return new Response("Missing required environment variables", { status: 500 });
        }

export interface Env {

    async fetch(request: Request, env: Env,): Promise<Response> {
        if (!env.BUCKET_URL_AUTH_GENERATION_KEY || !env.BUCKET_URL_SYMMETRIC_KEY) {
            return new Response("Missing required environment variables", { status: 500 });
        }

export interface Env {
    BUCKET_URL_AUTH_GENERATION_KEY: string;
    BUCKET_URL_SYMMETRIC_KEY: string;
}

export default {
    async fetch(request: Request, env: Env,): Promise<Response> {
        if (!env.BUCKET_URL_AUTH_GENERATION_KEY || !env.BUCKET_URL_SYMMETRIC_KEY) {
            return new Response("Missing required environment variables", { status: 500 });
        }

am i supposed to somehow use them here? how? do i change the param name or something?

I would still strongly recommend you avoid it. If you enable Domain Lockdown, you're protected from all known issues they had, but their responses to the situation have still been awful. They've still yet to inform all of their customers who remain unprotected because they don't do basic stuff like Sender Verification, and their platform is still vulnerable in a similar way if you sign up with any number of hosting providers that use them.

"Free" and secure/reliable email sending often doesn't go together, sadly. SendGrid has a reasonable free tier at 100/day, and then Postmark is great too, but only 100 free per month.

IEatBeans•5/9/24, 5:02 PM

Does this mean that currently this issue is still exploitable even with domain lockdown? Or do you mean that users that sign up from other providers are vulnerable, and not that that makes us (CF users) vulnerable?

J

James•5/9/24, 5:03 PM

If you turn on Domain Lockdown, then it's not exploitable with your domain. But many of their customers don't have this enabled, and if you sign up with another hosting provider that uses MailChannels, you can still send emails from many of their customers that'll pass security checks, yes.

J

James•5/9/24, 5:03 PM

They used to allow self-service for just $80 where you could do this. But they quietly removed that from their site. So now you have to signup via a third-party.

J

James•5/9/24, 5:04 PM

It all just reinforces their terrible communication throughout the process, and is a partnership that I think is irresponsible for Cloudflare to upkeep, personally.
