我正在尝试使用 erlang 库动力学连接到 kinesis。https://github.com/AdRoll/kinetic ...我的 development.config 中有我的 aws 密钥和秘密，但是我不确定 metadata_base_url 应该是什么，或者我还需要什么才能使其工作.. .目前我有：

%% -*- erlang -*-
[{kinetic,
    [{args, [
        % All of these values are optional
        % kinetic will get all of the context from the instance
        {metadata_base_url, "https://kinesis.us-east-1.amazonaws.com"},
        {aws_access_key_id, "mykey"},
        {aws_secret_access_key, "mysecret"},
        {iam_role, "kinetic"},

        {lhttpc_opts, [{max_connections, 5000}]}
    ]}]
}].

以下是我尝试启动它时的结果...

kinetic (master) $ make
==> lhttpc (get-deps)
==> jiffy (get-deps)
==> meck (get-deps)
==> kinetic (get-deps)
==> lhttpc (compile)
==> jiffy (compile)

==> kinetic (compile)

似乎如果在 ec2 集群之外运行动力学应用程序，您需要在配置中指定区域：

[{kinetic,
    [{args, [
         {region, "us-east-1"}, %% just an example
         ...
    ]}]
}].

并使用不会试图发现区域的固定版本的动力学。

第二种解决方案是为您的 http 服务设置 metadata_base_url 选项，该选项在获取“/latest/meta-data/placement/availability-zone”请求时将响应您所在的地区。

我从未使用过aws，有些陈述可能不正确。

错误消息说访问https://kinesis.us-east-1.amazonaws.com/latest/meta-data/placement/availability-zone返回错误 403：禁止访问。阅读 http 文档意味着身份验证是正确的，但您无权访问此资源。
