amazon-web-services - AWS API 网关 - 私有(private)端点 - 消息被禁止

Question

我正在尝试设置私有(private) AWS API 网关并从我的笔记本电脑连接到它。膝上型电脑驻留在 AWS Direct Connect'ed 到私有(private) VPC 的网络中。为此，我正在使用 AWS 提供的玩具示例“PetStore”API。

根据 this guide :

• 为我的 VPC 建立了 API 网关服务端点(禁用私有(private) DNS)
• 给它一个安全组，允许来自 本地网络(我的笔记本电脑所在的网络)
• 将 API 网关创建为私有(private) API
• 更新了资源政策
• 将 API 部署为阶段 V1

假设:

• AWS账号:123456789012
• AWS 区域:eu-central-1
• API 网关 ID:abcdefghij
• API 阶段:V1
• VPC 端点域:vpce-1234567890.execute-api.eu-central-1.vpce.amazonaws.com
• VPC端点IP:10.10.10.10

为了调用我的 API，我调用了以下 cURL 命令:

curl -v https://vpce-1234567890.execute-api.eu-central-1.vpce.amazonaws.com/V1/pets -H 'Host: abcdefghij.execute-api.eu-central-1.amazonaws.com' --noproxy "*"

这是结果:

* TCP_NODELAY set

有这个 {"message":"Forbidden"} 我不确定它来自哪里。还有错误 Could not resolve host: abcdefghij.execute-api.eu-central-1.amazonaws.com。

所以我的问题是:这个问题从何而来？

    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",

我遇到过与资源政策相关的类似问题。尝试使用以下策略:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:${AWS_REGION}:${AWS_ACCOUNT_ID}:${API_GETWAY_ID}/*/*/*",
            "Condition": {
                "StringNotEquals": {
                    "aws:sourceVpc": "${VPC_ENDPOINT_ID}"
                }
            }
        }
    ]
}

另外，确保 VPC 端点 ID 包含您的 vpce:
