            "Policies": []
        }
    ]
}

示例 2：列出与特定元数据匹配的所有参数

以下 describe-parameters 示例列出了与筛选器匹配的所有参数。

aws ssm 描述参数——过滤器 “键=类型，值=” StringList

输出：

{
    "Parameters": [
        {
            "Name": "MyStringListParameter",
            "Type": "StringList",
            "LastModifiedDate": 1582154764.222,
