ios - AWSS3 区域/plist 配置问题 'The service configuration is ` nil`

Question

我在使用 AWSS3 时遇到了一个奇怪的问题。

设置:

• AWS 移动中心
• 认知
• 动态数据库
• 中三

--> Cognito、Dynamo 甚至 S3(通过 Cognito 用户数据)工作。

但是我现在尝试使用以下代码直接连接到 AWS3:"

let transferManager = AWSS3TransferManager.default()
                            let uploadRequest = AWSS3TransferManagerUploadRequest()
                            uploadRequest?.bucket = "XXXXXXXXXXXX"
                            uploadRequest?.key = "user-data/" + awsId! + "/primary_profile_picture.png"
                            uploadRequest?.body = imgUrl as URL

                            transferManager.upload(uploadRequest!).continueWith(executor: AWSExecutor.mainThread(), block: { (task:AWSTask<AnyObject>) -> Any? in

                                if let error = task.error as? NSError {
                                    if error.domain == AWSS3TransferManagerErrorDomain, let code = AWSS3TransferManagerErrorType(rawValue: error.code) {
                                        switch code {
                                        case .cancelled, .paused:
                                            break
                                        default:
                                            print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                        }
                                    } else {
                                        print("Error uploading: \(uploadRequest?.key) Error: \(error)")
                                    }
                                    return nil
                                }

                                let uploadOutput = task.result
                                print("Upload complete for: \(uploadRequest?.key)")
                                return nil
                            })

我得到了错误:

AWSiOSSDK v2.5.1 [Debug] AWSInfo.m line:122 | -[AWSServiceInfo initWithInfoDictionary:checkRegion:] | Couldn't read the region configuration from Info.plist for the client. Please check your `Info.plist` if you are providing the SDK configuration values through `Info.plist`.

我正在使用从 AWS Mobiel HUB 下载的 plist 配置，因此我有点惊讶它不起作用(就像所有其他组件一样)。

有什么想法可能是什么问题吗？ plist 实际上包含存储桶 ID 和区域。

对我来说，我必须在上传之前使用以下代码配置凭据:

let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,identityPoolId:PoolID)
let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)

AWSServiceManager.default().defaultServiceConfiguration = configuration

其中 PoolID 是我的 Cognito 身份。我希望这对其他人有帮助。
