Cloud Storage for C++ ব্যবহার করে Cloud Storage রেফারেন্স তৈরি করা

// Get a reference to the storage service, using the default Firebase App
Storage* storage = Storage::GetInstance(app);

// Create a Cloud Storage reference from our storage service
StorageReference storage_ref = storage->GetReferenceFromUrl("gs://<your-cloud-storage-bucket>");

// Create a child reference
// images_ref now points to "images"
StorageReference images_ref = storage_ref.Child("images");

// Child references can also take paths delimited by '/'
// space_ref now points to "images/space.jpg"
// images_ref still points to "images"
StorageReference space_ref = storage_ref.Child("images/space.jpg");

// This is equivalent to creating the full reference
StorageReference space_ref = storage.GetReferenceFromUrl("gs://<your-cloud-storage-bucket>/images/space.jpg");

// Parent allows us to move to the parent of a reference
// images_ref now points to 'images'
StorageReference images_ref = space_ref.Parent();

// Root allows us to move all the way back to the top of our bucket
// root_ref now points to the root
StorageReference root_ref = space_ref.Root();

// References can be chained together multiple times
// earth_ref points to "images/earth.jpg"
StorageReference earth_ref = space_ref.Parent().Child("earth.jpg");

// null_ref is null, since the parent of root is an invalid StorageReference
StorageReference null_ref = space_ref.Root().Parent();

// Reference's path is: "images/space.jpg"
// This is analogous to a file path on disk
space_ref.full_path();

// Reference's name is the last segment of the full path: "space.jpg"
// This is analogous to the file name
space_ref.name();

// Reference's bucket is the name of the Cloud Storage bucket where files are stored
space_ref.bucket();

Storage* storage = Storage::GetInstance(app);

// Points to the root reference
StorageReference storage_ref = storage->GetReferenceFromUrl("gs://<your-bucket-name>");

// Points to "images"
StorageReference images_ref = storage_ref.Child("images");

// Points to "images/space.jpg"
// Note that you can use variables to create child values
std::string filename = "space.jpg";
StorageReference space_ref = images_ref.Child(filename);

// File path is "images/space.jpg"
std::string path = space_ref.full_path()

// File name is "space.jpg"
std::string name = space_ref.name()

// Points to "images"
StorageReference images_ref = space_ref.Parent();
