查看生命周期规则

开发过程中，您有任何问题可以在github上提交issue。接口参考文档详细介绍了每个接口的参数和使用方法。

您可以通过ObsClient.getBucketLifecycle查看桶的生命周期规则。以下代码展示了如何查看桶的生命周期规则：

// 引入obs库
// 使用npm安装
var ObsClient = require('esdk-obs-nodejs');
// 使用源码安装
// var ObsClient = require('./lib/obs');

// 创建ObsClient实例
var obsClient = new ObsClient({
       //推荐通过环境变量获取AKSK，这里也可以使用其他外部引入方式传入，如果使用硬编码可能会存在泄露风险。
       //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
       access_key_id: process.env.ACCESS_KEY_ID,
       secret_access_key: process.env.SECRET_ACCESS_KEY,
       server : 'https://your-endpoint'
});

obsClient.getBucketLifecycle({
       Bucket: 'bucketname'
}, (err, result) => {
       if(err){
              console.log('Error-->' + err);
       }else{
              console.log('Status-->' + result.CommonMsg.Status);
              if(result.CommonMsg.Status < 300 && result.InterfaceResult){
                     for(let i=0;i<result.InterfaceResult.Rules.length;i++){
                           console.log('Rule[' + i + ']:');
                           console.log('ID-->' + result.InterfaceResult.Rules[i]['ID']);
                           console.log('Prefix-->' + result.InterfaceResult.Rules[i]['Prefix']);
                           console.log('Status-->' + result.InterfaceResult.Rules[i]['Status']);
                           for(let j=0;j<result.InterfaceResult.Rules[i]['Transitions'].length;j++){
                                  console.log('Transition[' + j + ']:');
                                  console.log('Transition[StorageClass]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['StorageClass']);
                                  console.log('Transition[Date]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['Date']);
                                  console.log('Transition[Days]-->' + result.InterfaceResult.Rules[i]['Transitions'][j]['Days']);                            }
                           console.log('Expiration[Date]-->' + result.InterfaceResult.Rules[i]['Expiration']['Date']);
                           console.log('Expiration[Days]-->' + result.InterfaceResult.Rules[i]['Expiration']['Days']);
                           for(let k=0;k<result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'].length;k++){
                                  console.log('NoncurrentVersionTransition[' + k + ']:');
                                  console.log('NoncurrentVersionTransition[StorageClass]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'][k]['StorageClass']);
                                  console.log('NoncurrentVersionTransition[NoncurrentDays]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionTransitions'][k]['NoncurrentDays']);                            }
                           console.log('NoncurrentVersionExpiration[NoncurrentDays]-->' + result.InterfaceResult.Rules[i]['NoncurrentVersionExpiration']['NoncurrentDays']);
                     }
              }
       }
});
