操作步驟

1. 設置智能內容分析配置。

   調用接口CreateSearchIndex，設置媒資注冊完成后自動發起智能內容分析，同時設置入庫類型為人臉。

   com.aliyun.ice20201109.Client client = Sample.createClient("accessKeyId", "accessKeySecret"); 
   com.aliyun.ice20201109.models.CreateSearchIndexRequest createSearchIndexRequest = new com.aliyun.ice20201109.models.CreateSearchIndexRequest() 
          .setIndexType("face"); 
   com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions(); 
   client.createSearchIndexWithOptions(createSearchIndexRequest, runtime);

2. 注冊內容庫資源。

   調用接口RegisterMediaInfo，將待搜索的素材入庫，支持對圖片和視頻進行人臉搜索。

   com.aliyun.ice20201109.Client client = Sample.createClient("accessKeyId", "accessKeySecret");
   com.aliyun.ice20201109.models.RegisterMediaInfoRequest registerMediaInfoRequest = new com.aliyun.ice20201109.models.RegisterMediaInfoRequest()
           .setMediaType("video")
           .setTitle("face-test12")
           .setInputURL("oss://example-bucket/example.mp4");
   com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();
   client.registerMediaInfoWithOptions(registerMediaInfoRequest, runtime);

3. 獲取媒資內容信息。

   調用接口GetMediaInfo，確認視頻素材入庫成功。

   com.aliyun.ice20201109.Client client = Sample.createClient("accessKeyId", "accessKeySecret");
   com.aliyun.ice20201109.models.GetMediaInfoRequest getMediaInfoRequest = new com.aliyun.ice20201109.models.GetMediaInfoRequest()
           .setInputURL("oss://example-bucket/example.mp4");
   com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();
   client.getMediaInfoWithOptions(getMediaInfoRequest, runtime);

   如果返回的AiRoughData.Status值為SaveSuccess，表示入庫成功。

4. 根據人臉圖片搜索入庫媒資（粗搜）。

   調用接口SearchMediaByFace，同時設置人臉圖片URL，搜索人臉所在媒資的相關信息。

   com.aliyun.ice20201109.Client client = Sample.createClient("accessKeyId", "accessKeySecret");
   com.aliyun.ice20201109.models.SearchMediaByFaceRequest searchMediaByFaceRequest = new com.aliyun.ice20201109.models.SearchMediaByFaceRequest()
           .setFaceSearchToken("test001")
           .setPersonImageUrl("https://****.oss-cn-shanghai.aliyuncs.com/test/testFacePic.png");
   com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();
   client.searchMediaByFaceWithOptions(searchMediaByFaceRequest, runtime);

   返回示例：

   {
     "RequestId": "F0FBE61A-66FF-55C0-8900-EE816FA20B8D",
     "MediaInfoList": [
       {
         "MediaId": "92796460cd4571ed91c6e7e7c45b****"
       },
       {
         "MediaId": "b5a003f0cd3f71ed919fe7e7c45b****"
       }
     ],
     "Total": 2,
     "Code": "200",
     "Success": true
   }

5. 根據人臉圖片搜索入庫媒資片段（精搜）。

   調用接口SearchMediaClipByFace，同時輸入步驟 4中返回的MediaId，搜索人臉所在該媒資的片段信息。

   com.aliyun.ice20201109.Client client = Sample.createClient("accessKeyId", "accessKeySecret");
   com.aliyun.ice20201109.models.SearchMediaClipByFaceRequest searchMediaClipByFaceRequest = new com.aliyun.ice20201109.models.SearchMediaClipByFaceRequest()
           .setFaceSearchToken("test001")
           .setMediaId("92796460cd4571ed91c6e7e7c45b****");
   com.aliyun.teautil.models.RuntimeOptions runtime = new com.aliyun.teautil.models.RuntimeOptions();
   client.searchMediaClipByFaceWithOptions(searchMediaClipByFaceRequest, runtime);
