AWS Custom Authorize .Net Core 中的无效 Json

Question

我已经在 .net 核心中为 AWS 构建了一个自定义授权器。从 API 网关控制台对其进行测试时，我收到带有此错误的 ResponseCode 500。

无效的Json是这样的：

{
    "Version": "10/14/18",
    "Statement": [{
        "Effect": "Allow",
        "Action": ["apigateway: POST"],
        "Resource": ["arn:aws:lambda:us-west-2:278483347755:function:GetPolicy"]
    }]
}

对我来说这似乎还可以。在这里，Action 值取自 AWS 文档，Resource 是我的自定义授权方 lambda 方法的 ARN。

Answer 1

自定义授权 lambda 的响应不正确。

您可以在此处查看完整的详细信息 (https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-lambda-authorizer-output.html)，但是对于您的示例，您需要 return:

{
  "principalId": "user",
  "policyDocument": {
    "Version": "2012-10-17",
    "Statement": [
      {
        "Action": "execute-api:Invoke",
        "Effect": "Allow",
        "Resource": "arn:aws:execute-api:us-west-2:278483347755:k8ate5przg/ESTestInvoke-stage/GET/"
      }
    ]
  }
}

具体来说，您需要将策略嵌套在 policyDocument 密钥中，并且您授予的权限是 而不是 以便能够 POST API 网关，但允许调用网关后面的功能。
