图像内容审核（V3）

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)
                     .withProjectId(project_id)
const client = moderation.v3.ModerationClient.newBuilder()
                            .withCredential(credentials)
                            .withEndpoint(endpoint)
                            .build();
const request = new moderation.v3.CheckImageModerationRequest();
const body = new moderation.v3.ImageDetectionReq();
const listbodyCategories = new Array();
listbodyCategories.push("porn");
body.withUrl("http://www.xxxx.xxxx");
body.withCategories(listbodyCategories);
body.withEventType("head_image");
request.withBody(body);
const result = client.checkImageModeration(request);
result.then(result => {
    console.log("JSON.stringify(result)::" + JSON.stringify(result));
}).catch(ex => {
    console.log("exception:" + JSON.stringify(ex));
});

JSON.stringify(result)::{"request_id": "69b424920668cb15e6d25eef879a023b", "result": {"suggestion": "block", "category": "image_text", "details": [{"suggestion": "block", "category": "image_text", "confidence": 1.0, "qr_location": {"top_left_x": 74, "top_left_y": 66, "bottom_right_x": 151, "bottom_right_y": 142}, "qr_content": "http://xxxxxx/xxxxx", "label": "qr_code"}, {"suggestion": "block", "category": "image_text", "confidence": 0.98779297, "label": "ad"}, {"suggestion": "block", "category": "image_text", "confidence": 1.0, "label": "qr_code"}], "ocr_text": "xxxxxxxxx"}}
