从 iOS 应用程序 (Swift) 中的 S3 存储桶中删除文件

Question

我正在用 Swift 编写一个 iOS 应用程序，并且正在使用 Amazon S3 来存储文件。我想知道是否有人知道我如何通过命令以编程方式删除我的 S3 存储桶中的文件（而不是在存储桶生命周期中设置删除策略）。

提前致谢

Answer 1

您从 S3 存储桶中删除文件的代码应如下所示：

    let s3 = AWSS3.defaultS3()
    let deleteObjectRequest = AWSS3DeleteObjectRequest()
    deleteObjectRequest.bucket = "yourBucketName"
    deleteObjectRequest.key = "yourFileName"
    s3.deleteObject(deleteObjectRequest).continueWithBlock { (task:AWSTask) -> AnyObject? in
        if let error = task.error {
            print("Error occurred: \(error)")
            return nil
        }
        print("Deleted successfully.")
        return nil
    }

Swift 4+

如果你还没有初始

let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.APSoutheast1, identityPoolId: "yourPoolID")

let configuration = AWSServiceConfiguration(region:.APSoutheast1, credentialsProvider:credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration

和

let s3 = AWSS3.default()
guard let deleteObjectRequest = AWSS3DeleteObjectRequest() else {
    return
}
deleteObjectRequest.bucket = "yourBucketName"
deleteObjectRequest.key = "yourFileName"
s3.deleteObject(deleteObjectRequest).continueWith { (task:AWSTask) -> AnyObject? in
    
    if let error = task.error {
        print("Error occurred: \(error)")
        return nil
    }
    print("Deleted successfully.")
    return nil
    
}
