无服务器授权方请求不提供 methodArn 或有关调用 lambda 的任何信息

Question

我在从我定义的授权方 lambda 中的请求对象获取

methodArn

时遇到问题。我正在使用带有 golang 的无服务器。这是我拥有的代码的编辑设置。

main.go - 授权处理函数

func Handler(request events.APIGatewayCustomAuthorizerRequestTypeRequest) (events.APIGatewayCustomAuthorizerResponse, error) {
  // I have tried logging the entire request to cloud watch, see further down for the sample

  // i have code here to verify a jwt token
  return nil, nil
}

serverless.yml - 我的无服务器设置来注册函数并定义授权者

functions:
  permission_verify:
    handler: bin/handlers/permission/verify

package:
  patterns:
    - "!./**"
    - ./bin/**

provider:
  httpApi:
    authorizers:
      custom:
        functionName: permission_verify
        type: request

通过上述设置，我可以在其他微服务中使用授权者来验证

jwt

令牌，但现在我想向授权者添加更多功能，因此我需要请求中的

methodArn

存在。

这里是云监视在到达使用授权方的端点后的输出

        "identity": {
            "apiKey": "",
            "sourceIp": ""
        },
        "resourcePath": "",
        "httpMethod": "",
        "apiId": "redacted"
    }
}

我已经在互联网上搜索了一个解释和原因，因为在请求中没有关于调用 lambda 的信息无济于事。已经有相当长的时间了，我们将不胜感激任何帮助。
