我正在尝试从他们提供的 API 加载 AWS ip 范围，如下面的查询所示。如果我使用正确的网址“https://ip-ranges.amazonaws.com/ip-ranges.json”，我会收到如下所示的错误消息。但是，如果我对托管在我自己的网址“https://raw.githubusercontent.com/anandmudgerikar/aws-ips/main/ip-ranges.json”的 json 运行相同的查询，则查询工作正常。知道会发生什么吗？提前致谢。

Kusto 查询：

externaldata(syncToken:string, createDate:string, prefixes: dynamic , ipv6_prefixes: dynamic)
[ 
    h@'https://ip-ranges.amazonaws.com/ip-ranges.json'
    //h@'https://api.github.com/users/anandmudgerikar/repos'
    // h@'https://reqres.in/api/product/3'
    //h@'https://www.dropbox.com/s/24117ufuyfanmew/ip-ranges.json'
    //h@'https://raw.githubusercontent.com/anandmudgerikar/aws-ips/main/ip-ranges.json'
]
with(format= 'multijson', ingestionMapping=
'[{"Column":"syncToken","Properties":{"Path":"$.syncToken"}},' 
'{"Column":"createDate","Properties":{"Path":"$.createDate"}},' 
'{"Column":"prefixes","Properties":{"Path":"$.prefixes"}},'
'{"Column":"ipv6_prefixes","Properties":{"Path":"$.ipv6_prefixes"}}]')

这是我收到的错误消息：

仅官方支持此处记录的存储连接字符串；对其他人没有任何保证。

例如，为了遵守这一点，您可以将文件从其原始位置复制到 Azure Blob 容器，然后从那里查询它。
