swift - XCode Swift AWS S3 上传不工作

Question

由于某种原因，上传到 S3 不起作用，但我能够使下载功能正常工作。

这是我的上传代码:

@IBAction func uploadFile(_ 发送者: UIButton) {

    let CognitoRegionType = AWSRegionType.USWest2  // e.g. AWSRegionType.USEast1
    let CognitoIdentityPoolId = "us-west-2:3c00122a-866c-4ce4-9dd3-ee23c16e58f3"

    let DefaultServiceRegionType = AWSRegionType.USWest1 // e.g. AWSRegionType.USEast1
    let S3BucketName = "snappcastphotos"


    let credentialsProvider = AWSCognitoCredentialsProvider(regionType:CognitoRegionType, identityPoolId: CognitoIdentityPoolId)
    let configuration = AWSServiceConfiguration(region: DefaultServiceRegionType , credentialsProvider:credentialsProvider)
    AWSServiceManager.default().defaultServiceConfiguration = configuration


    let uploadRequest = AWSS3TransferManagerUploadRequest()
    uploadRequest?.bucket = S3BucketName
    uploadRequest?.key = "bingo"
    uploadRequest?.body = URL(fileURLWithPath: "/users/rhom/desktop/test.rtf")

    let transferManager = AWSS3TransferManager.default()
    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
    })
}

此代码会产生以下错误/输出:

上传错误:可选(“bingo”)错误:错误域=com.amazonaws.AWSS3ErrorDomain代码=0“(空)”UserInfo={HostId=KAsbvIqiY67dr/64f3uvZPB1Lr5Vj7eNNV198DLai/RG/tA+v3To8CBbnbFSM00V2COZnzebx/M=，消息=请求正文意外终止，Code=IncompleteBody, RequestId=A95236E53A1B8FE8}

大家有什么想法吗？我找不到任何线索来说明为什么使用 Cognito 和 S3 下载可以工作，但上传却不起作用......

看起来更像是一个授权错误。检查您是否具有此特定存储桶的写入权限，并检查您提供的路径是否正确，如果不匹配则无法工作。
