GetAuthorizationToken与 AWS SDK 或 CLI 配合使用

PDF

以下代码示例演示如何使用 GetAuthorizationToken。

操作示例是大型程序的代码摘录，必须在上下文中运行。在以下代码示例中，您可以查看此操作的上下文：

• 了解基础知识

CLI

AWS CLI

要获取默认注册表的授权令牌

以下 get-authorization-token 示例命令可获取默认注册表的授权令牌。

aws ecr get-authorization-token

输出：

{
    "authorizationData": [
        {
            "authorizationToken": "QVdTOkN...",
            "expiresAt": 1448875853.241,
            "proxyEndpoint": "https://123456789012.dkr.ecr.us-west-2.amazonaws.com"
        }
    ]
}
