Rackspace CloudFiles：检查文件是否存在

发布于 2024-10-01 03:26:23 字数 560 浏览 9 评论 0原文

我想通过 Rackspace Cloud API 通过我的站点代码检查 CDN 上是否存在文件。

最好的方法是什么？我目前正在使用以下内容：

... initialize API ... 

Dim containerItemList As List(Of String) = connection.GetContainerItemList("MyCDN") 

If containerItemList.Contains(MyFile) Then 
  'Blah blah 
End If

由于某种原因，这不起作用 - containerItemList 始终为空。我的容器肯定有对象，并且容器的名称是正确的（包括大小写）。

有没有更好/不同的方法来搜索/检查文件是否存在？理想情况下，它应该是不区分大小写的搜索。

另一种方法是尝试使用 connection.GetStorageItem 之类的方法获取对象，并检查异常，但显然这会损害性能。

有什么想法吗？任何语言的代码都可以，我只是在寻找最好的方法来做到这一点。

提前致谢！

I want to check for the existence of a file on the CDN through my site's code via the Rackspace Cloud API.

What would the best way to do this be? I am currently using the following:

... initialize API ... 

Dim containerItemList As List(Of String) = connection.GetContainerItemList("MyCDN") 

If containerItemList.Contains(MyFile) Then 
  'Blah blah 
End If

This isn't working for some reason - the containerItemList is always empty. My container definitely has objects, and the name of the container is right (including case).

Is there a better/different way to search/check for the existence of a file? Ideally, it should be a case-insensitive search.

Another way would be to try and get the object using something like connection.GetStorageItem, and check for exceptions, but obviously that would hurt performance.

Any ideas? Code in any language would be fine, I'm just looking for the best way to do this.

Thanks in advance!
