在WASB ListBlob中使用通配符 [英] Use wildcards in WASB ListBlobs

问题描述

我正在使用Azure .Net SDK列出Windows Azure存储Blob容器中的所有blob.

I'm using Azure .Net SDK to list all blobs from Windows Azure Storage Blob container.

let client = account.CreateCloudBlobClient()
let container = client.GetContainerReference("my-container")
let list = container.ListBlobs("data/2014-*-17/", false) // ! here

如您所见，我正在尝试使用通配符前缀过滤blob.

as you can see i'm trying to filter blobs by wildcarded prefix.

推荐答案

不幸的是，这无法正常工作，因为Azure存储不允许您进行服务器端wild card筛选.服务器端唯一可用的过滤选项是prefix过滤.

Unfortunately this won't work as Azure Storage does not allow you to do server-side wild card filtering. Only filtering option available to you server-side is prefix filtering.

因此，您要做的是列出以data/2014-开头的blob名称，然后在收到所有以data/2014-开头的blob名称后，将其余的过滤逻辑应用于客户端.

So what you would do is list blobs names of which starts with data/2014- and then apply rest of the filtering logic on the client side once you received all blobs names of which start with data/2014-.

let list = container.ListBlobs("data/2014-", false) // ! here
//Do client side filtering on the "list"
