List files
You can list all of the objects uploaded under a given prefix by setting the pageSize
. If the pageSize
is set lower than the total file size available, A single Storage.list
call only returns a subset of all the files. To list all the files with multiple calls, the user can use the nextToken
from the previous call response.
This will list all public files:
1let options = StorageListRequest.Options(pageSize: 1000)2let listResult = try await Amplify.Storage.list(options: options)3listResult.items.forEach { item in4 print("Key: \(item.key)")5}
1let sink = Amplify.Publisher.create {2 let options = StorageListRequest.Options(pageSize: 1000)3 try await Amplify.Storage.list(options: options)4}.sink {5 if case let .failure(error) = $0 {6 print("Failed: \(error)")7 }8}9receiveValue: { listResult in10 print("Completed")11 listResult.items.forEach { item in12 print("Key: \(item.key)")13 }14}
You can also list private or protected files by passing options. For example, to list all protected files owned by a user identified by the ID otherUserID
:
1let options = StorageListRequest.Options(accessLevel: .protected, targetIdentityId: "otherUserID", pageSize: 1000)2let listResult = try await Amplify.Storage.list(options: options)3listResult.items.forEach { item in4 print("Key: \(item.key)")5}
1let sink = Amplify.Publisher.create {2 let options = StorageListRequest.Options(accessLevel: .protected, targetIdentityId: "otherUserID", pageSize: 1000)3 try await Amplify.Storage.list(options: options)4}.sink {5 if case let .failure(error) = $0 {6 print("Failed: \(error)")7 }8}9receiveValue: { listResult in10 print("Completed")11 listResult.items.forEach { item in12 print("Key: \(item.key)")13 }14}
If you like limit the response to keys that begin with the specified path provide the path options:
1let options = StorageListRequest.Options(path: "path")2let listResult = try await Amplify.Storage.list(options: options)3listResult.items.forEach { item in4 print("Key: \(item.key)")5}
1let sink = Amplify.Publisher.create {2 let options = StorageListRequest.Options(path: "path")3 try await Amplify.Storage.list(options: options)4}.sink {5 if case let .failure(error) = $0 {6 print("Failed: \(error)")7 }8}9receiveValue: { listResult in10 print("Completed")11 listResult.items.forEach { item in12 print("Key: \(item.key)")13 }14}
