如何找到数据来源? [英] How to find the origin of data?

问题描述

到目前为止，文件只是像以下那样单独下载，而不是全部压缩在一个压缩文件中:

So far the files are just being downloaded individually like the following rather than all being in one zipped file:

s3client = boto3.client('s3')

t.download_file("firstbucket"，obj ['Key']，文件名)

t.download_file(‘firstbucket’, obj['Key'], filename)

推荐答案

如果要使用boto，则必须像您一样循环执行，并将每个项目添加到zip文件中.

if you want to use boto you'll have to do it in a loop like you have and add each item to a zip file.

使用CLI可以使用s3 sync，然后将其压缩 https://docs.aws.amazon.com/cli/Latest/reference/s3/sync.html

with the CLI you can use s3 sync and then zip that up https://docs.aws.amazon.com/cli/latest/reference/s3/sync.html

aws s3 sync s3://bucket-name ./local-location && zip bucket.zip ./local-location
