视频异步检测任务（推荐）_视频审核_内容安全_调用示例_Java SDK

本示例介绍如何使用Alibaba Cloud SDK for Java调用视频异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）。

如果使用本地文件或者二进制文件检测，请下载并在项目工程中引入Extension.Uploader工具类。

传入视频URL进行检测：

执行结果

本文代码示例正确的返回结果类似如下：

{
    "msg":"OK",
    "code":200,
    "data":[
        {
            "msg":"OK",
            "code":200,
            "dataId":"14574ce8-a71e-4fc4-b70e-25082692f320",
            "taskId":"vipZ********0g",
            "url":"http://aligreen-misc-shan********"
        }
    ],
    "requestId":"8642C40F-EA5B-4D62-A86A-0D9831E512BF"
}
