AWS iOS SDK：在两个不同的区域同时使用 S3 和移动分析

Question

我正在尝试在我的 Swift 项目中使用 AWS iOS SDK v2 集成 S3 和移动分析。问题是我正在尝试使用两个不同的区域（我正在使用我的主要区域，爱尔兰的 eu-west-1，但移动分析是 only available from us-east-1 in Virginia）。

我的 AppDelegate 中有以下内容来初始化移动分析：

    let credentialsProviderForMobileAnalytics = AWSCognitoCredentialsProvider.credentialsWithRegionType(
        AWSRegionType.USEast1,
        accountId: "my_account_id",
        identityPoolId: "pool_id",
        unauthRoleArn: "XXX",
        authRoleArn: "XXX"
    )

    let awsConfigurationForMobileAnalytics = AWSServiceConfiguration(
        region: AWSRegionType.USEast1,
        credentialsProvider: credentialsProviderForMobileAnalytics
    )

    AWSServiceManager.defaultServiceManager().setDefaultServiceConfiguration(awsConfigurationForMobileAnalytics)
    var mobileAnalytics = AWSMobileAnalytics(forAppId: "MyAwsAppId")

然后，在从 ViewController 调用的函数中，我想将图像上传到 S3，我有：

    let credentialsProviderForS3 = AWSCognitoCredentialsProvider.credentialsWithRegionType(
        AWSRegionType.EUWest1,
        accountId: "my_account_id",
        identityPoolId: "pool_id",
        unauthRoleArn: "XXX",
        authRoleArn: "XXX"
    )

    let awsConfigurationForS3 = AWSServiceConfiguration(
        region: AWSRegionType.EUWest1,
        credentialsProvider: credentialsProviderForS3
    )

    AWSServiceManager.defaultServiceManager().setDefaultServiceConfiguration(awsConfigurationForS3)

    var transferManager = AWSS3TransferManager.defaultS3TransferManager()

    var fileURL = NSURL(fileURLWithPath: NSTemporaryDirectory().stringByAppendingPathComponent("temp"))
    var uploadRequest1 : AWSS3TransferManagerUploadRequest = AWSS3TransferManagerUploadRequest()

        uploadRequest1.bucket = "mybucket"
        uploadRequest1.key =  "my-image.jpeg"
        uploadRequest1.body = fileURL
        var task = transferManager.upload(uploadRequest1)

如果我评论以上两个部分之一，相应的任务会完美完成（当分析代码被评论时，s3 工作，反之亦然），但它不能一起工作 - 我怀疑这是因为我正在使用 AWSServiceManager.defaultServiceManager().setDefaultServiceConfiguration() 设置默认服务配置，而我使用两个不同区域的事实不知何故弄乱了一切。它要么拒绝将事件记录到 Mobile Analytics，要么会中断上传并显示错误消息

NSUnderlyingError=0x17424ee20 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1001.)", NSErrorFailingURLKey=https://s3.amazonaws.com/mybucket/my-image.jpeg})

我尝试像这样为 S3 设置传输管理器（并评论上面的 setDefaultServiceConfiguration）：

    var transferManager = AWSS3TransferManager(configuration: awsConfigurationForS3, identifier: "S3")

导致上传过程中出现以下错误：

"Error Domain=com.amazonaws.AWSS3ErrorDomain Code=0 \"The operation couldn\U2019t be completed. (com.amazonaws.AWSS3ErrorDomain error 0.)\" UserInfo=0x1742e7e00 {HostId=sm4qLUbN2XfkNYefbSU4A95UXTwvNYEBz0+bALqeFzlcXJ7rOGWnr1Yg+8HoU4r2, Bucket=mybucket, Endpoint=mybucket.s3.amazonaws.com, Message=The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint., Code=PermanentRedirect, RequestId=568728899BC328B0}"

我也尝试将 "mybucket.s3.amazonaws.com" 作为存储桶名称传递，但这导致了一个错误，指出找不到存储桶。

我真的不确定接下来要尝试什么。希望你们能给我一些关于如何分离这两个集成并同时工作的指示。

问题是您将 S3 区域设置为 USEast1，但您的存储桶位于 EUWest1。根据日志，您在以下代码段中将 USEast1 设置为 awsConfigurationForS3 对象：

var transferManager = AWSS3TransferManager(configuration: awsConfigurationForS3, identifier: "S3")

您应该将 S3 区域更新为 EUWest1（您也可以将 Cognito Identity 区域更新为 EUWest1）。试试下面的代码片段：

// You can use the new constructor with fewer arguments.
let credentialsProviderForS3 = AWSCognitoCredentialsProvider.credentialsWithRegionType(
    AWSRegionType.EUWest1,
    identityPoolId: "pool_id"
)

let awsConfigurationForS3 = AWSServiceConfiguration(
    region: AWSRegionType.EUWest1,
    credentialsProvider: credentialsProviderForS3
)

// You need to retain a strong reference to an instance of AWSS3TransferManager until `- upload:` finishes executing. Making it a property is one way to do this.
self.transferManager = AWSS3TransferManager(configuration: awsConfigurationForS3, identifier: "S3")

var fileURL = NSURL(fileURLWithPath: NSTemporaryDirectory().stringByAppendingPathComponent("temp"))
var uploadRequest1 : AWSS3TransferManagerUploadRequest = AWSS3TransferManagerUploadRequest()
uploadRequest1.bucket = "mybucket"
uploadRequest1.key =  "my-image.jpeg"
uploadRequest1.body = fileURL

// `- upload:` is an asynchronous request. This means you need to retain a strong reference to `transferManager` until the async call completes.
transferManager.upload(uploadRequest1)
