SDK API Example

Construct a service client.

      
       
         
         String ak = System.getenv("HUAWEICLOUD_SDK_AK");
String sk = System.getenv("HUAWEICLOUD_SDK_SK");
String projectId = "projectId";
//Proxy information. If you need to use a proxy to access the service, add the proxy information here.
ProxyHostInfo proxyHostInfo = new ProxyHostInfo("proxy",
8080,
"UserName",
"Password"
);
//Service info
String url = "https://face.ap-southeast-1.myhuaweicloud.com";
String region = "ap-southeast-1";
AuthInfo authInfo = new AuthInfo(url, region, ak, sk);
FrsClient frsClient = new FrsClient(authInfo, projectId);
//FrsClient frsClient = new FrsClient(authInfo, projectId, proxyHostInfo);//If you need to use a proxy to access the service, add the proxy information to the third parameter.

        

      
     

Create a face set.

      
         CreateExternalFields createExternalFields = new CreateExternalFields();
createExternalFields.addField("testInteger", FieldType.INTEGER);
CreateFaceSetResult createFaceSetResult = frsClient.getV2().getFaceSetService().createFaceSet(faceSetName, faceSetCapacity, createExternalFields);

Add faces.

      
         String imageId = "image1";
File image = new File("data/face.jpg");
byte[] fileData = FileUtils.readFileToByteArray(image);
String imageBase64 = Base64.encodeBase64String(fileData);
AddExternalFields addExternalFields = new AddExternalFields();
addExternalFields.addField("testInteger", 123);
AddFaceResult addFaceResult = frsClient.getV2().getFaceService().addFaceByBase64(faceSetName, imageId, imageBase64, addExternalFields);

Invoke the Face Detection service.

      
         String obsUrl = "/bucket/face.jpg";
String attr = "1,2";
DetectFaceResult detectFaceResult = frsClient.getV2().getDetectService().detectFaceByObsUrl(obsUrl, attr);

NOTE:

In the preceding example, ak and sk indicate the access keys. To obtain the AK/SK, log in to the My Credentials page, choose Access Keys, and click Add Access Key.

projectId: Project ID. For details about how to obtain a project ID, see Obtaining a Project ID.
