Making firebase storage public for reading and writing on android

问题

I am new to firebase storage. Can anyone tell me how to make the storage files public for reading and writing?. The default code provided by firebase is given below. What changes should I make ?

service firebase.storage {
  match /b/image-view-b1cf5.appspot.com/o {
    match /{allPaths=**} {
      allow read, write: if request.auth != null;
    }
  }
}

回答1:

The documentation explains that if no rule expression is provided, the rule evaluates to true:

service firebase.storage {
  match /b/image-view-b1cf5.appspot.com/o {
    match /{allPaths=**} {
      // Allow access by all users
      allow read, write;
    }
  }
}

FYI: if you want public read only.

service firebase.storage {
  match /b/image-view-b1cf5.appspot.com/o {
    match /{allPaths=**} {
        allow read;
        allow write: if request.auth != null;
    }
  }
} 

回答3:

service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

Just Removing

if request.auth != null;

service firebase.storage {
  match /b/image-view-b1cf5.appspot.com/o {
    match /{allPaths=**} {
      // Allow access by all users
      allow read, write;
    }
  }
}

Happy Coding

回答5:

// Anyone can read or write to the bucket, even non-users of your app.
// Because it is shared with Google App Engine, this will also make
// files uploaded via GAE public.
service firebase.storage {
  match /b/{bucket}/o {
    match /{allPaths=**} {
      allow read, write;
    }
  }
}

Removing the authentication condition should work.
