I use cloudflare worker to build a VLESS node proxy to anti-consership and pass GFW in China

Cloudflare privide me this for free

It's really fantastic!

I never thought that Cloudflare's Workers could be so useful in breaking through network censorship and protecting my privacy.

Kitodi•1/30/24, 8:31 AM

Is there a way to handle the timeout when using TCP sockets? When this is called and the server has no response, the Cloudflare Worker get stuck at the

read()

read()

read()

read() function. Not confirmed in production, it might also get stuck there.

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

import { connect } from 'cloudflare:sockets'

connect(...).socket.readable.getReader().read()

I want to enable sass for an Worker API hosted on api.myapp.io.

I want to redirect my customer

api.customerapp.me

api.customerapp.me

api.customerapp.me

api.customerapp.me to my hosted worker

api.myapp.io

api.myapp.io

api.myapp.io

api.myapp.io

I've tried the following settings with no luck (Error code 522)

DNS Settings:

Type Name Content Proxy Status
AAAA api.myapp.io 100:: Proxied

Worker Routes:

Route Worker
api.myapp.io/ dh-api

SSL/TLS -> Custom Hostnames

Fallback Origin -> api.myapp.io

Custom Hostnames:

Custom Hostname Certificate status Expires on Hostname status Origin server
api.customerapp.me Active 2024-04-29 Active Default

I've added the generated TXT to my customer's dns setting.

Anything I'm missing? I'm following this doc https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin/

You're missing the wildcard route as per the docs you linked

C

Chaika•1/30/24, 2:17 PM

Worker Routes see the request as coming from

api.customerapp.me

api.customerapp.me

api.customerapp.me

api.customerapp.me, so it's not going to match

api.myapp.io

api.myapp.io

api.myapp.io

api.myapp.io, hence the need for the wildcard

Shadowfax•1/30/24, 2:20 PM

I can't select / for a wildcard because I've multiple workers on the zone . e.g. api.myapp.io, api2.myapp.io. If I set the wildcard it routes everything to the api.myapp.io. any workaround for that?

C

Chaika•1/30/24, 2:21 PM

If those other workers are worker routes, the wildcard shouldn't apply because the most specific rule takes precedence

C

Chaika•1/30/24, 2:22 PM

otherwise you could create a

*.<zonename>.com/*

*.<zonename>.com/*

*.<zonename>.com/*

*.<zonename>.com/*, service: none route as suggested in that post to prevent it from applying to your own zone, or I believe you could just create a route per customer domain if you only plan on having a few

Shadowfax•1/30/24, 3:38 PM

The second option seems to work. But I need to add them programmatically for each customer willing to have a custom hostname. I found the API doc to add a worker route https://developers.cloudflare.com/api/operations/worker-routes-create-route. That should work. But I was wondering if it is the right solution.

C

Chaika•1/30/24, 3:41 PM

it's not really the right solution no, there's a limit of 1000 routes or so and if you get too many they slow down overall routing (each one has to be evaluated)

C

Chaika•1/30/24, 3:42 PM

the right solution would just be a wildcard like they suggest, then using a single wildcard to exclude everything on your domain

C

Chaika•1/30/24, 3:42 PM

it is a bit messy though and potentially confusing for you in the future, you could buy a second domain dedicated to your customers/cf for saas to better isolate it

dave•1/30/24, 4:15 PM

Is this the correct way to have a write-once r2 put?

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8"
    },
    customMetadata: {
        "sup": "hey"
    },
    onlyIf: new Headers({
        "If-Unmodified-Since": new Date(0).toUTCString()
    })
})

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8"
    },
    customMetadata: {
        "sup": "hey"
    },
    onlyIf: new Headers({
        "If-Unmodified-Since": new Date(0).toUTCString()
    })
})

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8"
    },
    customMetadata: {
        "sup": "hey"
    },
    onlyIf: new Headers({
        "If-Unmodified-Since": new Date(0).toUTCString()
    })
})

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8"
    },
    customMetadata: {
        "sup": "hey"
    },
    onlyIf: new Headers({
        "If-Unmodified-Since": new Date(0).toUTCString()
    })
})

K

kian•1/30/24, 4:16 PM

seems fine, the only thing I'd say is that the Headers for

onlyIf

onlyIf

onlyIf

onlyIf are unnecessary

K

kian•1/30/24, 4:17 PM

you can handle it the same way as httpMetadata with a normal object

D

dave•1/30/24, 4:17 PM

this doesn't seem to work

const r2_put_prom = c.env.test.put(`test.json`, JSON.stringify({}, null, 2), {
    httpMetadata: {
        contentType: "application/json; charset=utf-8",
        "If-Unmodified-Since": new Date(0).toUTCString()

D

dave•1/30/24, 4:19 PM

doesn't that mean it will only upload if the file was uploaded before?

K

kian•1/30/24, 4:19 PM

same behaviour as the header

D

dave•1/30/24, 4:19 PM

huh weird

Kkian ```js onlyIf: { uploadedBefore: new Date(0) } ```

D

dave•1/30/24, 4:22 PM

the way I read this is: "only upload if the file was uploaded after 1970"

K

kian•1/30/24, 4:23 PM

it's "only upload if the file was uploaded before 1970" which is only possible if the file doesn't exist

K

kian•1/30/24, 4:23 PM

uploadedAfter

uploadedAfter

uploadedAfter

uploadedAfter would be the "only upload if the file was uploaded after 1970"
