3、图像反黄检测
URI：POST /v1.0/moderation/image/anti-porn

// 1. 配置好访问图像反黄检测服务的基本信息,生成对应的一个客户端连接对象
AisAccess service = ServiceAccessBuilder.builder()      
        .ak("######")                       // your ak
        .sk("######")                       // your sk
        .region("cn-north-1")               // 图像识别服务华北-北京一(cn-north-1)的配置
        .connectionTimeout(5000)            // 连接目标url超时限制
        .connectionRequestTimeout(1000)     // 连接池获取可用连接超时限制
        .socketTimeout(20000)               // 获取服务器响应数据超时限制
        .build();

//
// 2.构建访问图像反黄检测服务需要的参数，也可以用url
//
String uri = "/v1.1/moderation/image/anti-porn";
byte[] fileData = FileUtils.readFileToByteArray(new File("data/moderation-demo-1.jpg"));
String fileBase64Str = Base64.encodeBase64String(fileData);
