使用 aws-ruby-sdk 使用 AWS::S3 编写自定义文件名

Question

有没有办法使用aws-ruby-sdk gem 上传文件但具有动态（自定义）文件名？这似乎是一个显而易见的需求，但在documentation 中却找不到它。呜呜呜

我在文档中看到的唯一方法如下，它没有提供太大的灵活性。

## Uploading Files

## You can upload a file to S3 in a variety of ways. Given a path to a file (as a string) you can do any of the following:

# specify the data as a path to a file
obj.write(Pathname.new(path_to_file))

# also works this way
obj.write(:file => path_to_file)

# Also accepts an open file object
file = File.open(path_to_file, 'rb')
obj.write(file)

## All three examples above produce the same result. The file will be streamed to S3 in chunks. It will not be loaded entirely into memory.

到目前为止，我一直在使用 aws-s3 gem，它支持 AWS::S3::S3Object.store，但现在我使用的是 SDK gem，我不能同时使用它。

根据文档，初始化新对象的方式是

# new object, does not exist yet
obj = bucket.objects["my-text-object"]

然后您在实例上调用.write 来写入文件。也就是说，相当于下面的AWS::S3代码

S3Object.store('greeting.txt', 'hello world!', 'my-bucket')

应该是

obj = bucket.objects["greeting.txt"]
obj.write("hello world!")

其中bucket 是代表存储桶的实例。

s3 = AWS::S3.new
bucket = s3.buckets['my-bucket']
