无法通过 API Gateway POST 请求以异步模式执行 Lambda

Question

为什么目前没有办法通过网关 API 以异步模式执行 AWS Lambda，而不涉及仅用于调用 invoke() 方法的中间 Lambda？

即使我像这样添加集成：

r = client.put_integration(
    restApiId=rest_api_id,
    resourceId=resource_id,
    httpMethod='POST',
    type='AWS',
    integrationHttpMethod='POST',
    uri=uri,
    requestParameters={
        'integration.request.header.X-Amz-Invocation-Type': "'Event'",
        'integration.request.header.Invocation-Type': "'Event'"
    }
)

它仍然同步执行... 是否有一些平台限制？

我有一个示例 Swagger 文档，您可以将调用类型切换为 Lambda 函数。我想您已经知道如何映射标头以触发不同的调用类型，但我认为您可能忘记部署 API。
