Question

我在尝试使用AWS调用IOS Swift识别比较面孔api时遇到逻辑问题。 Swift尚无任何文档（截至本发布之时），但相信我可能已正确设置了请求，只是没有正确地调用它来接收响应对象并确认结果。

有什么建议吗？

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中的以下示例测试演示了如何比较ObjC中的两个面孔。

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

Swift中相应的代码段看起来像：

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")

希望有帮助！
