推荐答案

如果您只想复制一个对象

If you just want to copy one object copyObject API.

 var params = {
  Bucket: "destinationbucket", 
  CopySource: "/sourcebucket/sourceKeyName", 
  Key: "targetKeyName"
 };
 s3.copyObject(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
 });

如果要对存储桶中的所有对象进行递归执行，则

If you want to perform recursively for all objects in a bucket, then

1. 使用 listObjectsV2 API.

如果在 source-bucket 中启用了版本控制，并且您要复制密钥的特定版本，请调用

If versioning is enabled in the source-bucket and you want to copy a specific version of the key, Invoke the listObjectVersions API as well and get the Version-Id for each S3 Key.

注意:如果未启用版本控制，则可以忽略STEP-2.

分别为在步骤1和步骤2中获得的每个S3密钥和 Version-Id 调用 copyObject . Version-id 是可选的.

Call copyObject for each S3 Key and the Version-Id obtained in Step-1 and Step-2 respectively. Version-id is optional.
