为单个对象创建/添加lifecylce配置

Question

我想使用aws-sdk节点JS为S3 bucket中的某些对象设置不同的过期日期。为此，我使用了PutBucketLifecycleConfiguration和PutBucketLifecycle。据我所知，我使用了不同的前缀(=对象名）来为不同的对象设置过期日期。但这种方法不是在创造新的生命周期，而是在取代现有的生命周期。

const params = {
 Bucket: Env.AWS_BUCKET, /* required */
 LifecycleConfiguration: {
   Rules: [
    {
      Expiration: {
        Days: 1
    }, 
  Filter: {
     Prefix: fullPathOfObject
   }, 
  Status: "Enabled"
  }
 ]
}
};

const putBucketLifecycleConfigRequest = s3.putBucketLifecycleConfiguration(params);

putBucketLifecycleConfigRequest.
on('success', function(response: any) { 
console.log("success");
}).
on('error', function(error: any) {
console.log(error);
}).
on('complete', function(response: any) {
console.log("complete");
}).
send();

/***
const putBucketLifecycleRequest = s3.putBucketLifecycle(params);

putBucketLifecycleRequest.
 on('success', function(response: any) { 
 console.log("success");
 }).
 on('error', function(error: any) {
 console.log("error");
 }).
 on('complete', function(response: any) {
 console.log("complete");
 }).
 send();

**/

在AWS文档中:https://docs.AWS.amazon.com/awsjavascriptsdk/latest/AWS/s3.html#PutBucketLifecycle-property

它写的是“为bucket创建一个新的生命周期配置或替换现有的生命周期配置”。那么，我们不能为单个对象创建/添加lifecylce吗？

您试图等待回调，则需要等待promise

const params = {
    Bucket: 'aws-bucket-name' 
    LifecycleConfiguration: {
        Rules: [
            {
                Expiration: {
                    Days: 1,
                },
                Filter: {
                    Prefix: fullPathOfObject,
                },
                Status: 'Enabled',
            },
        ..add another rule here
        ],
    },
}

await s3.putBucketLifecycleConfiguration(params).promise()

根据下面的文档，如果还没有一个bucket生命周期，这将创建一个新的bucket生命周期，并替换现有的生命周期。所以这是预期的工作。

据我所知，你需要再加一条规则
