使用wget或curl下载具有共享访问签名的Azure Blob

我有一个Azure Blob容器,它是私有的.我们称之为https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension.

如果我的容器设置为“仅对blob进行公共读取访问”,那么一切都很有效.

$wget https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension
--2016-04-28 16:11:15-- https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension

HTTP request sent,awaiting response... 200 OK

Saving to: ‘my-file.my-extension’

如果我的容器设置为“无公共访问”,并且我创建了一个名为my-policy的访问策略,其中包含一年的读/写/删除/列表,我将获得以下直接链接：https：// my-account. blob.core.windows.net/my-blob-container/my-file.my-extension?sv=2015-02-21u0026amp;si=my-policyu0026amp;sr=bu0026amp;sig=y+2pvIuR9rGQdvm/QKp0xNCWE+1G/ 2IqjHkWMhRcPUA =

如果我将链接复制到浏览器中,文件会自动下载.如果我使用wget,我会收到404错误：

$wget https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension?sv=2015-02-21&si=my-policy&sr=b&sig=y%2B2pvIuR9rGQdvm%2FQKp0xNCWE%2B1G%2F2IqjHkWMhRcPUA%3D
