问题
I just made a firebase cloud function :
exports.deleteAfterSevenDays = functions.https.onRequest((req, res) => {...
I deployed the function and got a function URL. When I request this url from my browser I get the following message :
"Error: Forbidden Your client does not have permission to get URL /200 from this server."
I have just updated to firebase Blaze plan because I thought there were limitations with Spark plan, but it still doesn't work.
In my firebase cloud function logs it is written "Function execution took 572 ms, finished with status code: 302".
My cron job "has been disabled automatically because of too many failed executions".
Do you see what's wrong?
回答1:
Cloud function should have a role with member called "All users" to invoke this function from anywhere/anyone irrespective of an authorization.
Without Authorization:
- Go to the cloud function tab
- Select your cloud function (check box)
- Click "Add members" under Permissions tab in the right side
- Enter "allUsers" under "New memebers"
- Select Role as "Cloud Functions -> Cloud Functions Invoker"
- Save
- Test your cloud function by just pasting it in the browser
With Authorization:
It's always a good practice to set authorization on your cloud functions
Note: Cloud functions throwing error with "403 Forbidden - Your client does not have permission to get URL" should be called by authorized users.
Simple test:
Click on Cloud shell(icon) terminal in the top
type - gcloud auth print-identity-token
copy the generated token
forming Authorization key to be passed while calling cloud function 4.1 Authorization: bearer generated_token
Use above Authorization key while calling your cloud function
Note:
- Never make a cloud function available to allUsers

Changing the IAM role(Cloud Functions Invoker) for targeted cloud function to allUsers should solve this issue. https://console.cloud.google.com/functions
