Have a look at the request in your browsers devtools when you upload, you'll see that it starts with some plain text then it is followed by the actual image bytes. You can use ctx.request.text() to parse this yourself or look for a library that can handle multipart form content for you

Hello,

I'm trying to disable local mode so that I can access my production D1 instance via my Pages Function.

I had originally expected there to just be the option to press

l

l like when running workers in dev to disable this, but there isn't. This led me to discover the

--local false

--local false

--local false

--local false flag. However, this doesn't do anything. I can see my binding is still referencing a local miniflare database.

When running

npx wrangler pages dev public --local false

npx wrangler pages dev public --local false

npx wrangler pages dev public --local false

npx wrangler pages dev public --local false I see:

Hey, me again...

So I have a Pages Function in the root of my functions directory called

[articleId].ts

[articleId].ts

. A catch all for all

domain.com/<id>

domain.com/<id>

.
This is great, however, it also catches

domain.com

domain.com

itself. Which I do not want, as it will trigger the function for no reason.

I thought I could disable this via

_routes.json

_routes.json

:

{
  "version": "1",
  "include": ["/*"],
  "exclude": "/"
}

{
  "version": "1",
  "include": ["/*"],
  "exclude": "/"
}

Hi all,

I was wondering what the recommended approach is for ingesting and processing form data, when deploying to cloudflare pages. Cloudflare pages supports the ideas of functions by adding a

/functions

/functions

directory and placing scripts there: https://developers.cloudflare.com/pages/functions/get-started/, however I also noticed that Astro has this guide on endpoints: https://docs.astro.build/en/guides/endpoints/, and it seems this could also work? However, when using Cloudflare Pages for deployment, I am not sure which method is recommended. If i follow Astro's guide on endpoints, would these automatically be served by Pages in a similar way to the Functions? Anyone with experience with deploying Astro to Cloudflare Pages can shine some light on this?

Thank you!

Beny•3/18/24, 3:58 PM

There's a plugin which is good for processing forms using a middleware function: https://developers.cloudflare.com/pages/functions/plugins/static-forms/
However if you're using Astro I assume you'll want to use their middleware instead.

Here's an example:

// src/middleware.js
export async function onRequest({ request, locals }, next) {
    // Check if the current request path matches the specific form action path
    if (new URL(request.url).pathname === '/form-path' && request.method === 'POST') {
        try {
            // Process form data
            const formData = await request.formData();

            // Example of form data processing.
            if(formData.get('name') !== "john") {
                throw new Error("Name must be john!")
            }

            // After processing successfully, redirect to `/form-submitted`
            return Response.redirect(new URL("/form-submitted", request.url), 302);
        } catch (error) {
            // If there's an error in processing, set `locals.formError`
            // This can later be checked in the endpoint handling the form submission
            locals.formError = error.message;
        }
    }

    // If the path does not match, proceed with the normal request flow.
    return next();
}

// src/middleware.js
export async function onRequest({ request, locals }, next) {
    // Check if the current request path matches the specific form action path
    if (new URL(request.url).pathname === '/form-path' && request.method === 'POST') {
        try {
            // Process form data
            const formData = await request.formData();

            // Example of form data processing.
            if(formData.get('name') !== "john") {
                throw new Error("Name must be john!")
            }

            // After processing successfully, redirect to `/form-submitted`
            return Response.redirect(new URL("/form-submitted", request.url), 302);
        } catch (error) {
            // If there's an error in processing, set `locals.formError`
            // This can later be checked in the endpoint handling the form submission
            locals.formError = error.message;
        }
    }

    // If the path does not match, proceed with the normal request flow.
    return next();
}

// src/middleware.js
export async function onRequest({ request, locals }, next) {
    // Check if the current request path matches the specific form action path
    if (new URL(request.url).pathname === '/form-path' && request.method === 'POST') {
        try {
            // Process form data
            const formData = await request.formData();

            // Example of form data processing.
            if(formData.get('name') !== "john") {
                throw new Error("Name must be john!")
            }

You shouldn't need to use Astro's middleware to do this though.

You should be able to use Endpoints, the middleware just adds complexity because you need to check the path yourself.

I am using a Pages Function as a proxy to my backend API, to get it to work I had to install CF SSL Cert, and use SSL on my backend API host, I was unable to use regular http. However, I was wondering if I must also use port 443 for my backend API or if I can specify one and that will work? I figured I'd ask before I went through trying it out, since everything is technically working right now.

I can't seem to provide a custom port for my backend, it fails with a 521 error code.
