無法連接到來自IntelliJ的AWS rekognition API

我一直在玩亞馬遜的新rekognition API，並且無法從IntelliJ運行它們的example Java應用程序。我在我的pom.xml使用Maven構建項目，幷包括AWS SDK如下：無法連接到來自IntelliJ的AWS rekognition API

<dependency> 
    <groupId>com.amazonaws</groupId> 
    <artifactId>aws-java-sdk</artifactId> 
    <version>${aws-java-sdk.version}</version> 
</dependency>

從我可以告訴，我的應用程序似乎是某處在這裏失敗：

AmazonRekognitionClient rekognitionClient = new AmazonRekognitionClient(credentials) 
     .withEndpoint("s3-us-west-2.amazonaws.com"); 
rekognitionClient.setSignerRegionOverride("us-west-2"); 
try { 
    DetectFacesResult result = rekognitionClient.detectFaces(request); 
    ObjectMapper objectMapper = new ObjectMapper(); 
    System.out.println("Result = " + objectMapper.writeValueAsString(result)); 
} catch (AmazonRekognitionException e) { 
    e.printStackTrace(); 
}

...那我得到的錯誤是：

com.amazonaws.services.rekognition.model.AmazonRekognitionException: null (Service: AmazonRekognition; Status Code: 400; Error Code: null; Request ID: null) 
    at com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1545)

我也應該注意到，我跑在AWS CLI操作（見下文）和成功。

aws rekognition detect-faces \ 
--image '{"S3Object":{"Bucket":"Bucketname","Name":"s3ObjectKey"}}' \ 
--attributes "ALL" \ 
--region us-east-1 \ 
--profile adminuser

你能告訴你的'request'？ –

我的請求：'{Image：{S3Object：{Bucket：rekognitionexample，Name：obama.jpg，}}，Attributes：[ALL]}' –

你爲什麼試圖使用S3端點連接到rekognition服務？您應該使用重新識別端點...請參閱http://docs.aws.amazon.com/general/latest/gr/rande.html#rekognition_region – mickzer

您可以使用下面的代碼來創建rekognition客戶端的一個實例：

AWSCredentials credentials; 
try { 
    credentials = new ProfileCredentialsProvider("default").getCredentials(); 
} catch (Exception e) { 
    throw new AmazonClientException("Cannot load the credentials from the credential profiles file. " 
      + "Please make sure that your credentials file is at the correct " 
      + "location (/Users/<userid>/.aws/credentials), and is in a valid format.", e); 
} 
AmazonRekognitionClient rekognitionClient = new AmazonRekognitionClient(credentials) 
     .withEndpoint("rekognition.eu-west-1.amazonaws.com"); 
rekognitionClient.setSignerRegionOverride("eu-west-1");
