I am using Firebase for Auth and image storage--images that are publically available thoughout my app, like profile pictures. How do I set up the permissions appropriately so that any user (or even non-authenticated entities) can read these public images?
My security rules:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
In your question, you say that you want non-authenticated entities to see the images, but your rules are set up to only allow authenticated entities to see them. You can change your rules to:
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read;
allow write: if request.auth != null;
}
}
}

Now that firebase has forced using rules scrambling to find the right solution here.
I have all images in the main bucket and every user once logged in has something like
bucket
users/{uid}/uploads
where all there uploaded photos go (would be cool to restrict to images at some point)
these should be public read and write, if write can be only for the authenticated user even better, but auth to read is necessary.
there is a special folder before a user is authenticated and need upload a profile pic
users/uploads
which should be read write to the public here is what i have but the second rule takes precedence
service firebase.storage {
match /b/{bucket}/o {
match /users {
match /uploads {
match /object {
allow read, write
}
}
}
match /{allPaths=**} {
allow read, write: if request.auth != null
}
}
}
I'm thinking it probably needs to be a not /users/uploads forthen then do do this but the documentation is bad for if else statements. any thoughts?
EDIT: this rule set works for reading correctly but still can't write when unauthenticated during sign up
service firebase.storage {
match /b/{bucket}/o {
// Allow only authenticated users to upload
// Any user can read
match /users/uploads {
allow read, write;
}
// Only allow user with auth.uid == uid to read/write
match /users/{uid}/uploads {
allow read: if true;
allow write: if request.auth.uid == uid;
}
}
}
You can try the following rules that'll restrict access to user's own directory and also have a public folder:
rules_version="2";
service firebase.storage {
match /b/{bucket}/o {
// Allow only authenticated users to upload
// Any user can read
match /users/uploads {
allow read: if true;
allow write: if request.auth != null;
}
// Only allow user with auth.uid == uid to read/write
match /users/{uid}/uploads {
allow read: if true;
allow write: if request.auth.uid == uid;
}
}
}
Do note that if request.auth != null; allows everyone write (including delete) so try using allow create: only.
I need to set firebase storage rules so unauthenticated users can upload a file but can't read a file.
So far I have:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow write: if true
allow read: if false
}
}
}
Is this the correct way to do this?
This rule will help you to read only if user is authenticated else it won't allow. For more details you can read docs
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read: if request.auth != null;
allow write: if true;
}
}
}
I am trying to get images from firebase firestore, while trying to get image download url there is this exception :
W/StorageUtil(10206): no auth token for request
(similar questions with this error not solve the problem)
Although my security rules allow read and write I getting this error still.
Any ideas what is the problem with this?
Code for getting image url :
static Future<dynamic> loadImage(BuildContext context, String image) async {
return await FirebaseStorage.instance.ref().child(image).getDownloadURL();
}
Calling this loadImage function :
Future<Widget> getImage(BuildContext context, String imgName) async {
Image image;
await FireStorageService.loadImage(context, imgName).then((value) {
print(value);
image = Image.network(value.toString(), fit: BoxFit.scaleDown);
return image;
});
}
Calling this getImage function :
child: FutureBuilder(
future: getImage(context, "/images/test1.jpg"),
...
)
My firebase storage rules :
rules_version = '2';
service firebase.storage {
match /images/{imageId} {
allow read,write;
}
}
Storage Rules ss:
My firebase store currently :
Navigate to Firebase console
In Sidebar under Develop open Storage
Open Rules tab replace the rule on your console with the rule below:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write
}
}
}
And Publish
Done
(2022): Recently, I solved with following the Firestore basic security rules (for authenticated user):
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
You can see this in their website: https://firebase.google.com/docs/rules/basics?authuser=1#cloud-storage_1
I do not suggest that using allow read, write; directly. If your application has a authentication, then you need to check if auth is null or not.
I fixed it by changing the rules.
Go to Firebase project>Storage>Rules.
By default, you are not allowed to upload on Firebase so you have to change that.
Default rules
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if false;
}
}
}
Change allow read, write: if false; to allow read, write;
Go to Project Settings -> App Check -> Products
Change the Storage from Enforce -> Unenforced
This works for me by changing the rules in firebase.
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write
}
}
}
i need to set a folder public with only read permisions in firebase storage, my security rules are
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write:if request.auth.uid != null;
}
match /{platos=**} {
allow read;
}
}
}
the folder is called platos and im not sure if those rules are secured the others folders must have protection only for logued users
The first rule should concern your folder, because otherwise the first rule is applied which rejects reads:
rules_version = '2';
service firebase.storage {
match /b/{bucket}/o {
match /platos/{allPaths=**} {
allow read;
allow write: if request.auth != null;
}
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
}
}
You can just delete the authentication code request.auth.uid != null and give only the read permission.
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read;
}
}
}
I'm storing images under uid/PropertyPhotos/Property# (where # is incremented as images are uploaded). The uid belongs to the user that posted the image, not the current logged on Firebase user. What I'd like is to allow anyone to view those images. How do I modify the storage rule below to allow that?
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read, write: if request.auth != null;
}
// we want anyone to view the property images (no auth, publicy readable)
match /{uid}/PropertyPhotos {
allow read;
}
}
}
