SDK API Example

1. Construct a service client.

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

   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.

2. Create a face set.

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

3. Add faces.

   1 2 3 4 5 6 7

   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);

4. Invoke the Face Detection service.

   1 2 3

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

   

   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.
