将 CreatePublicKey 与 Amazon SDK 或 CLI 配合使用

创建 CloudFront 公有密钥

以下示例通过在名为 pub-key-config.json 的 JSON 文件中提供参数来创建 CloudFront 公有密钥。必须先拥有 PEM 编码的公有密钥，然后才能使用此命令。有关更多信息，请参阅《Amazon CloudFront 开发人员指南》中的创建 RSA 密钥对。

aws cloudfront create-public-key \
    --public-key-config file://pub-key-config.json

文件 pub-key-config.json 是当前文件夹中包含以下内容的 JSON 文档：请注意，公有密钥以 PEM 格式编码。

{
    "CallerReference": "cli-example",
    "Name": "ExampleKey",
    "EncodedKey": "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxPMbCA2Ks0lnd7IR+3pw\nwd3H/7jPGwj8bLUmore7bX+oeGpZ6QmLAe/1UOWcmZX2u70dYcSIzB1ofZtcn4cJ\nenHBAzO3ohBY/L1tQGJfS2A+omnN6H16VZE1JCK8XSJyfze7MDLcUyHZETdxuvRb\nA9X343/vMAuQPnhinFJ8Wdy8YBXSPpy7r95ylUQd9LfYTBzVZYG2tSesplcOkjM3\n2Uu+oMWxQAw1NINnSLPinMVsutJy6ZqlV3McWNWe4T+STGtWhrPNqJEn45sIcCx4\nq+kGZ2NQ0FyIyT2eiLKOX5Rgb/a36E/aMk4VoDsaenBQgG7WLTnstb9sr7MIhS6A\nrwIDAQAB\n-----END PUBLIC KEY-----\n",
    "Comment": "example public key"
}

输出：

以下代码示例读取公有密钥并将其上传到 Amazon CloudFront。
