I assume that is for when you boot up another instance of "./stripe.exe listen --forward-to", no? Cuz it gives a new key.

When the stripe developers log their rawbody using express on nodejs instead, they get:
<Buffer 7b 0a 20 20 22 69 64 22 3a 20 22 65 76 74 ... 2344 more bytes>

But cloudflare worker functions does not have a way to get that from the request?

It is in local that it's not working for me.

So you set the stripe initilization to this (?):

const stripe = new Stripe(env.STRIPE_SECRET_KEY, { 
    apiVersion: '2023-10-16', 
    httpClient: Stripe.createFetchHttpClient()
  })

const stripe = new Stripe(env.STRIPE_SECRET_KEY, { 
    apiVersion: '2023-10-16', 
    httpClient: Stripe.createFetchHttpClient()
  })

const stripe = new Stripe(env.STRIPE_SECRET_KEY, { 
    apiVersion: '2023-10-16', 
    httpClient: Stripe.createFetchHttpClient()
  })

const stripe = new Stripe(env.STRIPE_SECRET_KEY, { 
    apiVersion: '2023-10-16', 
    httpClient: Stripe.createFetchHttpClient()
  })

And then run:

const rawBody = await request.text()
const stripeSignature = request.headers.get('stripe-signature')

event = await stripe.webhooks.constructEventAsync(rawBody, stripeSignature, env.STRIPE_WEBHOOK_SECRET)

const rawBody = await request.text()
const stripeSignature = request.headers.get('stripe-signature')

event = await stripe.webhooks.constructEventAsync(rawBody, stripeSignature, env.STRIPE_WEBHOOK_SECRET)

const rawBody = await request.text()
const stripeSignature = request.headers.get('stripe-signature')

event = await stripe.webhooks.constructEventAsync(rawBody, stripeSignature, env.STRIPE_WEBHOOK_SECRET)

const rawBody = await request.text()
const stripeSignature = request.headers.get('stripe-signature')

Mike Nomitch•5/3/24, 4:02 PM

Hi all

. I'm having trouble getting a hello world with functions working locally or when deployed. Hoping I can get some guidance here.

I used a Solid JS starter project from here (https://developers.cloudflare.com/pages/framework-guides/deploy-a-solid-site/) and then added a

/functions/hello.js

/functions/hello.js

file in the root of the project that looks like this:

export function onRequest(context) {
  return new Response("Hello, world!");
}

export function onRequest(context) {
  return new Response("Hello, world!");
}

I expected that if I ran

npx wrangler pages dev

npx wrangler pages dev

and then went to

http://localhost:8788/hello

http://localhost:8788/hello

I would just see "Hello, world!" but instead of that I see the 404 page of my frontend app.

I've also deployed to prod and see the same thing at "/hello". In the CF UI in the functions tab I see this in the routing config:

{
  "baseURL": "/",
  "routes": [
    {
      "method": "",
      "module": [
        "hello.js:onRequest"
      ],
      "mountPath": "/",
      "routePath": "/hello"
    }
  ]
}

{
  "baseURL": "/",
  "routes": [
    {
      "method": "",
      "module": [
        "hello.js:onRequest"
      ],
      "mountPath": "/",
      "routePath": "/hello"
    }
  ]
}

{
  "baseURL": "/",
  "routes": [
    {
      "method": "",
      "module": [
        "hello.js:onRequest"
      ],
      "mountPath": "/",
      "routePath": "/hello"
    }
  ]
}

{
  "baseURL": "/",
  "routes": [
    {
      "method": "",
      "module": [
        "hello.js:onRequest"
      ],
      "mountPath": "/",
      "routePath": "/hello"
    }
  ]
}

and locally

wrangler pages functions build

wrangler pages functions build

works fine.

Any ideas? I'm thinking its some small basic bit of config I'm missing or maybe a misunderstanding of what a Hello World looks like?
