问题
I make a simple audio recording web app using Firebase Hosting. I would like to record audio on browser and upload it to Cloud Storage. When I deploy and access my app, I can record audio. However the app failed to upload the audio to Cloud Storage.
(I use Windows 10, Windows Subsystems for Linux, Debian 10.3 and Google Chrome browser. )
This is an error message in browser's console.
firebasestorage.googleapis.com/v0/b/ondoku-dc29c.appspot.com/o?name=audio%2Fspeech.wav:1
Failed to load resource: the server responded with a status of 403 ()
This is a screenshot of browser's console.
I searched the Internet and found that an 403() error means that you do not have permission to upload to firebase storage.
However, I couldn't found the way to get permission.
Could you give me any advice? Thank you in advance.

For you to get the permissions correctly, you need to check your Firebase Storage Security Rules. Configuring them correctly, will provide the access and permissions needed for the audios to be upload to the storage. By default, the rules will ask you to be authenticated, so you need to check to confirm. This way, you can either change your application to have authentication (best option) or the rules.
You can change the rules by accessing the Firebase Console and accessing the tab Rules. If you check the rules and they are similar or equal to the one below, it's confirming that you will need to be authenticated to write in the database, which is causing the error you are seeing.
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
For tests only, you can change the rules to the below one, so you can bypass the error, while you don't fix the authentication. Please, keep in mind that this will open the accessing to read and write to not authenticated users, so it should be used only for testing.
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth == null;
}
}
}
Let me know if the information helped you!
