Google云端存储:下载其他名称的文件 [英] Google Cloud Storage: download a file with a different name
问题描述
我想知道是否可以从Google Cloud Storage下载名称与存储桶中名称不同的文件.
I'm wondering if it's possible to download a file from Google Cloud Storage with a different name than the one that has in the bucket.
例如，我在Google Cloud Storage中存储了一个名为123-file.txt的文件，但是当我下载该文件时，我想选择一个不同的名称，例如file.txt
For example, in Google Cloud Storage I have stored a file named 123-file.txt but when I download it I would like choose a different name, let's say file.txt
I've noticed that the link for download it is like: https://storage.cloud.google.com/bucket_name%2F123-file.txt?response-content-disposition=attachment;%20filename=123-file.txt
因此，我尝试将其更改为: https://storage.cloud.google .com/bucket_name％2F123-file.txt?response-content-disposition =附件；％20filename = file.txt
So I've tried to change it to: https://storage.cloud.google.com/bucket_name%2F123-file.txt?response-content-disposition=attachment;%20filename=file.txt
但是它仍然继续以123-file.txt而不是file.txt下载
But it still keeps downloading as 123-file.txt instead of file.txt
推荐答案
response-content-disposition参数只能由授权请求使用.匿名链接不起作用.您有几种选择:
The response-content-disposition parameter can only be used by authorized requests. Anonymous links don't work with it. You have a few options:
-
特定对象的内容处置是其元数据的一部分，可以永久设置.如果您始终希望使用特定名称下载特定文件，则可以永久设置该对象的内容处置元数据.
The content-disposition of a particular object is part of its metadata and can be permanently set. If you always want a specific file to be downloaded with a specific name, you can just permanently set the content-disposition metadata for the object.
您还可以生成包含response-content-disposition查询参数的签名URL.然后，用户将提出授权请求以下载资源.
You can also generate signed URLs that include the response-content-disposition query parameter. Then the users will be making authorized requests to download the resource.
