通过阅读本文，您可以了解通过服务端SDK调用OpenAPI发起并查询智能媒体服务截图任务的示例代码。

使用说明

发起截图任务前，需要先创建截图模板。通过TemplateId（截图模板ID）发起截图任务，发起截图任务时，支持对截图模板参数进行覆盖重置，截图任务处理成功后，可以根据返回的JobId（任务ID）查询该截图任务的详细信息、截图任务列表及截图的访问URL。

示例代码

您可以通过阿里云OpenAPI开发者门户在线调试。

package com.aliyun.ice.sample;

import com.aliyun.ice20201109.Client;
import com.aliyun.ice20201109.models.*;
import com.aliyun.teaopenapi.models.Config;

public class Sample {

    public static void main() throws Exception {

        // 阿里云账号AccessKey拥有所有API的访问权限，建议您使用RAM用户进行API访问或日常运维。
        // 本示例以将AccessKey ID和 AccessKey Secret保存在环境变量为例说明。配置方法请参见：https://help.aliyun.com/document_detail/378657.html
        com.aliyun.credentials.Client credentialClient = new com.aliyun.credentials.Client();
        Config config = new Config();
        config.setCredential(credentialClient);

        // 如需硬编码AccessKey ID和AccessKey Secret，代码如下，但强烈建议不要把AccessKey ID和AccessKey Secret保存到工程代码里，否则可能导致AccessKey泄露，威胁您账号下所有资源的安全。
        // config.accessKeyId = <yourAccessKeyId>;
        // config.accessKeySecret = <yourAccessKeySecret>;

        config.endpoint = "ice.cn-shanghai.aliyuncs.com";
        Client client = new Client(config);

        // 创建截图模板
        String snapshotTemplateConfig = "{\"Type\":\"Normal\",\"FrameType\":\"normal\",\"Time\":0,\"Count\":10}";
        CreateCustomTemplateRequest createCustomTemplateRequest = new CreateCustomTemplateRequest()

            .setTemplateConfig(snapshotTemplateConfig);
        CreateCustomTemplateResponse createCustomTemplateResponse = client.createCustomTemplate(createCustomTemplateRequest);
        String templateId = createCustomTemplateResponse.getBody().getCustomTemplate().getTemplateId();
        System.out.println("template id: " + templateId);

        // 发起截图任务
        SubmitSnapshotJobRequest submitSnapshotJobRequest = new SubmitSnapshotJobRequest()
            .setName("sdk_sample_snapshot_job")
            .setInput(new SubmitSnapshotJobRequest.SubmitSnapshotJobRequestInput()
                .setType("Media")
                .setMedia("3945e42d01823498****"))
            .setOutput(new SubmitSnapshotJobRequest.SubmitSnapshotJobRequestOutput()
                .setType("Media")
                .setMedia("3945e42d01823498****"))
            .setTemplateConfig(new SubmitSnapshotJobRequest.SubmitSnapshotJobRequestTemplateConfig()
                .setTemplateId(templateId));
        SubmitSnapshotJobResponse submitSnapshotJobResponse = client.submitSnapshotJob(submitSnapshotJobRequest);
        String jobId = submitSnapshotJobResponse.getBody().getJobId();
        System.out.println("job id: " + templateId);

        // 查询截图任务详细信息
        GetSnapshotJobRequest getSnapshotJobRequest = new GetSnapshotJobRequest()
            .setJobId(jobId);
        GetSnapshotJobResponse getSnapshotJobResponse = client.getSnapshotJob(getSnapshotJobRequest);
        System.out.println("request id: " + getSnapshotJobResponse.getBody().getRequestId());

        // 获取截图任务列表
        ListSnapshotJobsRequest listSnapshotJobsRequest = new ListSnapshotJobsRequest()
            .setPageSize(5);
        ListSnapshotJobsResponse listSnapshotJobsResponse = client.listSnapshotJobs(listSnapshotJobsRequest);
        System.out.println("request id: " + listSnapshotJobsResponse.getBody().getRequestId());

        // 获取截图任务输出图片的访问URL
        GetSnapshotUrlsRequest getSnapshotUrlsRequest = new GetSnapshotUrlsRequest()
            .setJobId("20b48fb04483915d4f2cd8ac****")
            .setPageSize(5);
        GetSnapshotUrlsResponse getSnapshotUrlsResponse = client.getSnapshotUrls(getSnapshotUrlsRequest);
        System.out.println("request id: " + getSnapshotJobResponse.getBody().getRequestId());
    }
