AWS API网关-专用endpoint-禁止消息

Question

我正在尝试设置一个专用AWS API网关，并从笔记本电脑连接到它。笔记本电脑驻留在一个直接连接到专用VPC的网络中。为此，我使用AWS提供的玩具示例“PetStore”API。

根据本指南：

• 为我的VPC建立了一个API网关服务endpoint（禁用私有DNS）

假设：

• AWS账号：123456789012

要调用API，我调用以下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 "*"

这就是结果：

*   Trying 10.10.10.10...
* TCP_NODELAY set
* Connected to vpce-1234567890.execute-api.eu-central-1.vpce.amazonaws.com (10.54.251.244) port 443 (#0)

这里有一个{“消息”：“禁止”}我不确定它是从哪里来的。而且错误无法解析主机：abcdefghij。执行api。欧盟中央1号。亚马逊。com。

所以我的问题是：这个问题来自哪里？

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:eu-central-1:123456789012:abcdefghij/*"
        }
    ]
}

之前的AWS API网关专用API配置文档有点误导，我推动了文档的更新。

创建专用API网关时，有两个关键字段需要注意：

1. VPCendpointID

用于API下的VPCendpoint配置-

Endpoint Configuration:
   VPC End Point ID:
       *Your VPC End Point ID(This is the VPC End point ID with     
    com.amazonaws.ap-southeast-1.execute-api permission)

在API下-

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Deny",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:eu-central-1:123456789012:abcdefghij/*",
            "Condition": {
                "StringNotEquals": {
                    "aws:sourceVpc": "Change to your VPC ID"
                }
            }
        },
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:eu-central-1:123456789012:abcdefghij/*"
        }
    ]
}

最后，这确实是资源策略相关的。经过其他一些尝试，我们回到了以前的策略，不知何故，它开始工作了（也许我们第一次忘记部署应用编程接口）

这是对我们有效的政策：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": "*",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:eu-central-1:123456789012:abcdefghij/*"
        }
    ]
}

Answer 3

我遇到过与资源策略相关的类似问题。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}"
                }
            }
        }
    ]
}

此外，请确保VPCendpointID包括您的vpce：
