获取桶归档存储对象直读策略

// 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保存在环境变量中为例，运行本示例前请先在本地环境中设置环境变量AccessKeyID和SecretAccessKey。
// 前端本身没有process对象，可以使用webpack类打包工具定义环境变量，就可以在代码中运行了。
// 您可以登录访问管理控制台获取访问密钥AK/SK，获取方式请参见https://support.huaweicloud.com/intl/zh-cn/usermanual-ca/ca_01_0003.html
const AK = process.env.AccessKeyID
const SK = process.env.SecretAccessKey
// 【可选】如果使用临时AKSK和SecurityToken访问OBS，则同样推荐通过环境变量获取
const security_token= process.env.SecurityToken
// server填写Bucket对应的Endpoint, 这里以中国-香港为例，其他地区请按实际情况填写。
const server = "https://obs.ap-southeast-1.myhuaweicloud.com"
// 创建ObsClient实例
var obsClient = new ObsClient({
    access_key_id: AK,
    secret_access_key: SK,
    server: server
});

    try {
        const params = {
            Bucket: 'examplebucket',
        };
        // 获取桶归档存储对象直读策略
        const result = await obsClient.getBucketDirectColdAccess(params);
        if (result.CommonMsg.Status < 300) {
            console.log("Get bucket(%s)'s DirectColdAccess successful!", params.Bucket);
