使用 wget 或 curl 下载具有共享访问签名的 Azure Blob
Download Azure Blob with Shared Access Signature using wget or curl
我知道我可以使用 Azure CLI 来完成此操作，但我想使用常见的 Linux/Unix 命令。
我有一个私有的 Azure Blob 容器。我们称它为 https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension。
如果我的容器设置为 "Public read access for blobs only"，一切正常。
$ wget https://my-account.blob.core.windows.net/my-blob-container/my-file.my-extension

如果我的容器设置为 "No public access"，并且我创建了一个名为 my-policy 的访问策略，Read/Write/Delete/List 一年，我直接得到以下 link : 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
如果我将 link 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：

由于某些 URL 编码 的性质，您必须确保在进行 wget 调用时 URL 包含在语音标记中（如果你做 curl 也是一样）
我可以在容器级别创建一个 SAS，允许我读取存储中的文件
wget "https://azurerpkg.blob.core.windows.net/azurer/doggies.jpg?st=2016-06-06T07%3A56%3A00Z&se=2018-06-07T07%3A56%3A00Z&sp=rl&sv=2015-04-05&sr=c&sig=nKQz5BcWoUaASBzSW7Hv0TzfMbTFcf0f%2B5mMtmTwQ2A%3D" -k -O "doggies.jpg"
如果我在 blob 级别创建特定的 SAS，我的 wget 也可以工作
wget "https://azurerpkg.blob.core.windows.net/azurer/doggies.jpg?st=2016-06-06T07%3A56%3A00Z&se=2018-06-07T07%3A56%3A00Z&sp=rl&sv=2015-04-05&sr=b&sig=ntNFXS6fUlHVkiqoqj2rHg1Pw6gSNosnYqj3CQ6GIrg%3D" -k -O doggies.jpg
有效的共享访问签名查询字符串需要以下参数的参数：
- st
- se
- sp
- sr
- 签名
你的似乎缺少 se 组件，即到期日。
