本示例介绍如何使用Alibaba Cloud SDK for Java查询视频异步检测结果。
前提条件
在使用本教程之前，请确保已完成以下操作：
- 使用Alibaba Cloud SDK for Java，您需要一个阿里云账号和访问密钥（AccessKey）。 请在阿里云控制台中的AccessKey管理页面上创建和查看您的AccessKey。
- 确保您已经安装了Alibaba Cloud SDK for Java，准确的SDK版本号，请参见 阿里云开发工具包（SDK）。

代码示例
- 文本内容检测代码示例如下：
import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import com.aliyuncs.CommonRequest; import com.aliyuncs.CommonResponse; import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.exceptions.ServerException; import com.aliyuncs.http.FormatType; import com.aliyuncs.http.MethodType; import com.aliyuncs.profile.DefaultProfile; import java.util.*; public class Scan { public static void main(String[] args) throws Exception { DefaultProfile profile = DefaultProfile.getProfile( "<your-region-id>", // 您的可用区ID "<your-access-key-id>", // 您的AccessKey ID "<your-access-key-secret>"); // 您的AccessKey Secret IAcsClient client = new DefaultAcsClient(profile); CommonRequest request = new CommonRequest(); request.setSysMethod(MethodType.POST); request.setSysDomain("green.cn-hangzhou.aliyuncs.com"); request.setSysVersion("2018-05-09"); request.setSysUriPattern("/green/text/scan"); List<Map<String, String>> tasks = new ArrayList<Map<String, String>>(); Map<String, String> task1 = new HashMap<String, String>(); task1.put("dataId",UUID.randomUUID().toString()); // 待检测的文本，长度不超过10000个字符 task1.put("content","张三，你妈妈身体怎么样？"); Map<String, String> task2 = new HashMap<String, String>(); task2.put("dataId",UUID.randomUUID().toString()); // 待检测的文本，长度不超过10000个字符 task2.put("content","test content"); tasks.add(task1); tasks.add(task2); HashMap<String, Object> body = new HashMap<String, Object>(); body.put("tasks",tasks); // 检测场景，文本垃圾检测传递：antispam body.put("scenes","antispam"); request.setHttpContent(JSON.toJSONString(body).getBytes("UTF-8"), "UTF-8", FormatType.JSON); // 请务必设置超时时间 request.setSysConnectTimeout(3000); request.setSysReadTimeout(6000); try { CommonResponse response = client.getCommonResponse(request); JSONObject dataJson = JSON.parseObject(response.getData()); System.out.println(JSON.toJSONString(dataJson, true)); } catch (ServerException e) { e.printStackTrace(); } catch (ClientException e) { System.out.println("ErrCode:" + e.getErrCode()); System.out.println("ErrMsg:" + e.getErrMsg()); System.out.println("RequestId:" + e.getRequestId()); } } } - 如果您认为我们的文本检测结果与您的期望不符，您可以通过文本垃圾结果反馈接口纠正算法检测结果，代码示例如下：
import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; import com.aliyuncs.CommonRequest; import com.aliyuncs.CommonResponse; import com.aliyuncs.DefaultAcsClient; import com.aliyuncs.IAcsClient; import com.aliyuncs.exceptions.ClientException; import com.aliyuncs.exceptions.ServerException; import com.aliyuncs.http.FormatType; import com.aliyuncs.http.MethodType; import com.aliyuncs.profile.DefaultProfile; import com.aliyuncs.profile.IClientProfile; public class TextFeedback { public static void main(String[] args) throws Exception { IClientProfile profile = DefaultProfile.getProfile( "<your-region-id>", // 您的可用区ID "<your-access-key-id>", // 您的AccessKey ID "<your-access-key-secret>"); // 您的AccessKey Secret IAcsClient client = new DefaultAcsClient(profile); CommonRequest request = new CommonRequest(); request.setSysMethod(MethodType.POST); request.setSysDomain("green.cn-hangzhou.aliyuncs.com"); request.setSysVersion("2018-05-09"); request.setSysUriPattern("/green/text/feedback"); JSONObject data = new JSONObject(); data.put("taskId", "txt5********1rGrSC"); data.put("label", "abuse"); System.out.println(JSON.toJSONString(data, true)); request.setHttpContent(data.toJSONString().getBytes("UTF-8"), "UTF-8", FormatType.JSON); // 请务必设置超时时间 request.setSysConnectTimeout(3000); request.setSysReadTimeout(6000); try { CommonResponse response = client.getCommonResponse(request); JSONObject dataJson = JSON.parseObject(response.getData()); System.out.println(JSON.toJSONString(dataJson, true)); } catch (ServerException e) { e.printStackTrace(); } catch (ClientException e) { System.out.println("ErrCode:" + e.getErrCode()); System.out.println("ErrMsg:" + e.getErrMsg()); System.out.println("RequestId:" + e.getRequestId()); } } }
执行结果
- 文本内容检测正确的返回结果类似如下：
{ "msg":"OK", "code":200, "data":[ { "msg":"OK", "code":200, "dataId":"d4cc69c1-577a-4a0b-a83e-eeb2705cd767", "results":[ { "rate":99.91, "suggestion":"block", "details":[ { "label":"abuse" } ], "label":"abuse", "scene":"antispam" } ], "content":"张三，你妈妈身体怎么样？", "taskId":"txt5********1rGrSC" }, { "msg":"OK", "code":200, "dataId":"17cd7ab5-73ba-44d1-8138-274d22b5cb5a", "results":[ { "rate":99.91, "suggestion":"pass", "label":"normal", "scene":"antispam" } ], "content":"test content", "taskId":"txt4$aZ*******Ln-1rGrP1" } ], "requestId":"1B4BC8A4-EAF8-44FB-A7D4-07DCE8A96FBC" } - 文本检测内容反馈正确的返回结果类似如下：
{ "msg":"OK", "code":200, "requestId":"D43F32C9-D9F3-41C6-9CC8-E22745A426D2" }
