Java使用者提取输入的输入参数

问题描述

在下面的代码中,我正在使用Java Consumer,我想提取输入参数 event 的值,以在代码的其他地方使用。可以做到吗?如果可以,怎么办?

func application(_ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    
    do {
        try Amplify.add(plugin: AWSCognitoAuthPlugin())
        try Amplify.add(plugin: AWSS3StoragePlugin())
        try Amplify.configure()
        print("Amplify configured with storage plugin")
    } catch {
        print("Failed to initialize Amplify with \(error)")
    }
    
    self.testUploadData()
    
    return true
}

func testUploadData() {
    let dataString = "Example file contents"
    let data = dataString.data(using: .utf8)!
    Amplify.Storage.uploadData(key: "ExampleKey",data: data,progressListener: { progress in
            print("Progress: \(progress)")
        },resultListener: { (event) in
            switch event {
            case .success(let data):
                print("Completed: \(data)")
            case .failure(let storageError):
                print("Failed: \(storageError.errorDescription). \(storageError.recoverySuggestion)")
        }
    })
}
