将文件上传至 Cloud Storage 后,您还可以删除它们。
删除文件
如需删除某个文件,请先为该文件创建引用。然后,对该引用调用 delete()
方法。
Kotlin
// Create a storage reference from our app val storageRef = storage.reference // Create a reference to the file to delete val desertRef = storageRef.child("images/desert.jpg") // Delete the file desertRef.delete().addOnSuccessListener { // File deleted successfully }.addOnFailureListener { // Uh-oh, an error occurred! }
Java
// Create a storage reference from our app StorageReference storageRef = storage.getReference(); // Create a reference to the file to delete StorageReference desertRef = storageRef.child("images/desert.jpg"); // Delete the file desertRef.delete().addOnSuccessListener(new OnSuccessListener<Void>() { @Override public void onSuccess(Void aVoid) { // File deleted successfully } }).addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception exception) { // Uh-oh, an error occurred! } });
处理错误
导致删除文件时出错的原因有很多,包括文件不存在,或者用户不具备删除相应文件的权限。如需详细了解这些错误,请参阅文档的处理错误部分。
