图像内容审核（V2）

示例代码中可以使用Url或Image配置图像信息(代表使用url或者图像的base64)，示例中以url为例配置完成后运行即可。

const core = require('@huaweicloud/huaweicloud-sdk-core');
const moderation = require("@huaweicloud/huaweicloud-sdk-moderation");
// 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全；
// 本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和HUAWEICLOUD_SDK_SK、HUAWEICLOUD_SDK_PROJECT_ID。 
const ak = process.env.HUAWEICLOUD_SDK_AK;
const sk = process.env.HUAWEICLOUD_SDK_SK;
const projectId = process.env.HUAWEICLOUD_SDK_PROJECT_ID;

const endpoint = "https://moderation.cn-north-4.myhuaweicloud.com"; //把cn-north-4替换成服务所在的区域。
const credentials = new core.BasicCredentials()
                     .withAk(ak)
                     .withSk(sk)
const client = moderation.ModerationClient.newBuilder()
                            .withCredential(credentials)
                            .withEndpoint(endpoint)
                            .build();
const request = new moderation.RunImageModerationRequest();
const body = new moderation.ImageDetectionReq();
const listbodyCategories = new Array();
listbodyCategories.push("terrorism");
listbodyCategories.push("porn");
body.withCategories(listbodyCategories);
body.withModerationRule("default");
body.withUrl("https://XXX.jpg");  //此处替换为公网可以访问的图片地址
request.withBody(body);
const result = client.runImageModeration(request);
result.then(result => {
    console.log("JSON.stringify(result)::" + JSON.stringify(result));
}).catch(ex => {
    console.log("exception:" + JSON.stringify(ex));
});

JSON.stringify(result)::{"result": {"detail": { "porn": [{"confidence": 0.9883, "label": "normal"}, {"confidence": 0.0039, "label": "porn"}, {"confidence": 0.0078, "label": "sexy"}], "terrorism": [{"confidence": 0.0002, "label": "terrorist"}, {"confidence": 0.0002, "label": "fascist"}, {"confidence": 0.0001, "label": "cult"}, {"confidence": 0.0002}, {"confidence": 0.0001, "label": "kidnap"}, {"confidence": 0.0006, "label": "riot"}, {"confidence": 0.0001, "label": "parade"}, {"confidence": 0.0002, "label": "corpse"}, {"confidence": 0.0001, "label": "bloody"}, {"confidence": 0.0001, "label": "knife"}, {"confidence": 0.0001, "label": "gun"}, {"confidence": 0.0002, "label": "military_weapon"}, {"confidence": 0.0, "label": "special_characters"}, {"confidence": 0.9994, "label": "normal"}], "ad": [{"confidence": 0.0, "label": "ad"}, {"confidence": 1.0, "label": "normal"}]}, "suggestion": "pass", "category_suggestions": { "ad": "pass", "terrorism": "pass", "porn": "pass"}}}
