Question

为什么目前没有办法通过Gateway API在异步模式下执行AWS Lambda而不涉及调用invoke（）方法的中间Lambda？

即使我添加这样的集成：

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...... 是否存在某些平台限制？

我有一个示例Swagger文档，您可以将调用类型切换为Lambda函数。我猜你已经有了如何映射头来触发不同的调用类型，但我想你可能会忘记部署API。
