阅读更多关于 Firebase Storage upload php

问题 I'm currently trying to upload to the Firebase Cloud Storage using php, but running into an issue. I have a form in html, that takes the uploaded file (in my case an image), and passes it to a php file. This image is very small, 12.8kB, and a JPEG image. The php file takes the image, and tries to upload it to the storage. My current php code is roughly: $storage = new StorageClient(['projectId' => '<my_project_id> ']); $bucket = $storage->bucket('images'); $bucket->upload($_FILES[

Firebase Admin SDK to download/retrieve files on Google Cloud Storage

阅读更多关于 Firebase Admin SDK to download/retrieve files on Google Cloud Storage

I'm trying to download some images that I have uploaded to my Google Cloud Storage (aka into buckets). I'm unable to use the .ref() method on any of my const storage or const bucket because they are part of the admin SDK. The admin.storage has only the method .bucket() ( https://firebase.google.com/docs/reference/admin/node/admin.storage.Storage ). I'm able to access the buckets. bucket.getFiles() works, and the result comes out to be an Array of Files objects with a ton of metadata (like file name, bucket owner, etc.). How can I get my images from the cloud storage and insert them into html

问题 I'm using multiple databases in a Firebase project. Cloud functions for the main (default) database work great, however, I cannot make them work for a secondary database. For example I want to make a read request on a node with admin privileges: //this works admin.database().ref(nodePath).once('value')... This works in the main database, however, if I want to execute the command on another database, it doesn't work: //this doesn't work admin.database(secondaryDatabaseUrl).ref(nodePath).once(

Quota exceeded when updating users with Firebase Admin SDK - how can I request more?

阅读更多关于 Quota exceeded when updating users with Firebase Admin SDK - how can I request more?

We try to update many users in our multitenant setup, when a whole tenant needs to be enabled/disabled. With this, we sometimes run into QUOTA_EXCEEDED errors, especially for large tenants with many users. I have asked how to do this better here: Disable many users at once As there are currently no bulk operations to update users with the Firebase Admin SDK , how can I request a quota raise? I do not see an enable/disable users in the Firebase Authentication Limits The error message does not indicate what has to be changed. It only says Exceeded quota for updating account information. I do not
