视频同步检测任务 - Java SDK

本示例介绍如何使用Alibaba Cloud SDK for Java调用视频同步检测任务进行视频审核。

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）。

            System.out.println("RequestId:" + e.getRequestId());
        }
    }
}

执行结果

正确的返回类似如下：

{
    "msg":"OK",
    "code":200,
    "data":[
        {
            "msg":"OK",

                {
                    "frames":[

                            "offset":0,

                    "rate":99.9,
                    "suggestion":"pass",
