AWS Recognition使用IOS Swift比較人臉

Question

嘗試使用IOS Swift調用AWS Recognition Compare Faces api的邏輯上遇到問題。 Swift尚無任何文檔（截至本文發布），但相信我可能已正確設置了請求，只是未正確調用它以接收響應對象並確認結果。

有什么建議嗎？

let sourceImage = AWSRekognitionImage()
let sourceImageS3Object = AWSRekognitionS3Object()
sourceImageS3Object?.bucket = "face-badges"
sourceImageS3Object?.name = "me.jpg"
sourceImage?.s3Object = sourceImageS3Object

let targetImage = AWSRekognitionImage()
let targetImageS3Object = AWSRekognitionS3Object()
targetImageS3Object?.bucket = "face-badges"
targetImageS3Object?.name = "me2.jpg"
targetImage?.s3Object = targetImageS3Object

let request = AWSRekognitionCompareFacesRequest()
request?.similarityThreshold = 90
request?.sourceImage = sourceImage
request?.targetImage = targetImage

let key = "testCompareFaces"
let credentialsProvider = AWSCognitoCredentialsProvider(regionType:.USEast1,
                                                        identityPoolId:"xxxxx")
let configuration = AWSServiceConfiguration(region:.USEast1, credentialsProvider:credentialsProvider)

AWSRekognition.register(with: configuration!, forKey: key)
AWSRekognition(forKey: key).compareFaces(AWSRekognitionCompareFacesRequest()).continueWith(block: {(_ task: AWSTask) -> Any in
    print("completed")

    return true;

}).waitUntilFinished()

SDK中的以下示例測試演示了如何在ObjC中比較兩個面孔。

https://github.com/aws/aws-sdk-ios/blob/master/AWSRekognitionUnitTests/AWSGeneralRekognitionTests.m#L60

Swift中相應的代碼段看起來像：

let key = "testCompareFaces"
let configuration = AWSServiceConfiguration(region: AWSRegionUSEast2, credentialsProvider: nil)
AWSRekognition.register(with: configuration, forKey: key)
AWSRekognition(for: key).compareFaces(AWSRekognitionCompareFacesRequest()).continue(withBlock: {(_ task: AWSTask) -> Any in
    print("completed")

希望有幫助！
