如何使用Boto在S3中设置元数据? [英] How to set metadata in S3 using boto?

问题描述

我正在尝试将文件推送到S3期间设置元数据.

I am trying to set metadata during pushing a file to S3.

这是它的样子:

def pushFileToBucket(fileName, bucket, key_name, metadata):
    full_key_name = os.path.join(fileName, key_name)
    k = bucket.new_key(full_key_name)
    k.set_metadata('my_key', 'value')
    k.set_contents_from_filename(fileName)

由于某种原因，这会在set_metadata上抛出错误:

For some reason this throws error at set_metadata saying :

boto.exception.S3ResponseError: S3ResponseError: 403 Forbidden
<?xml version="1.0" encoding="UTF-8"?><Error><Code>SignatureDoesNotMatch</Code></Error>

当我删除此 set_metadata 部分时，文件将被正确存储.不知道我在做什么错.如果访问密钥无效，则无论如何都不会保存文件！

And when I remove this set_metadata part, the file is getting stored correctly. Not sure what I am doing wrong. If the access key was invalid, then it wouldn't have saved the file anyway!

推荐答案

已解决此问题.显然，我们在元数据键名称中不能包含下划线.

Got this fixed. Apparently we cannot have an underscore in the metadata key name.
