aws-sdk S3:使用listObjectsV2列出所有键的最佳方法 [英] aws-sdk S3: best way to list all keys with listObjectsV2

问题描述

使用vcode版本的 listObjects API调用，您将可以从 SO回答中完成类似的操作.

With the v1 version of the listObjects API call, you would have done something like from this SO answer.

var allKeys = [];
function listAllKeys(marker, cb) {
  s3.listObjects({Bucket: s3bucket, Marker: marker}, function(err, data){
     allKeys.push(data.Contents);

    if(data.IsTruncated)
       listAllKeys(data.NextMarker, cb);
    else
       cb();
  });
}

listObjectsV2 函数的等效项是什么?

What would be the equivalent of the listObjectsV2 function?

推荐答案

这是从存储桶中获取键列表的代码.

Here is the code to get the list of keys from a bucket.

var params = {
    Bucket: 'bucket-name'    
};

var allKeys = [];
listAllKeys();
function listAllKeys() {
    s3.listObjectsV2(params, function (err, data) {
        if (err) {
            console.log(err, err.stack); // an error occurred
        } else {
            var contents = data.Contents;
            contents.forEach(function (content) {
                allKeys.push(content.Key);
            });

            if (data.IsTruncated) {
                params.ContinuationToken = data.NextContinuationToken;
                console.log("get further list...");
                listAllKeys();
            } 

        }
    });
}
