用于复合API调用的Spring Cloud Gateway？
[英]Spring Cloud Gateway for composite API calls?
问题描述
I am starting to build a Microservice API Gateway, and I am considering Spring Cloud to help me with the routing. 
我开始构建微服务API网关，并且正在考虑使用Spring Cloud来帮助我进行路由。 But some calls to the Gateway API will need multiple requests to different services. 但是，对Gateway API的某些调用将需要对不同服务的多个请求。
Lets say I have 2 services: Order Details Service and Delivery Service . 可以说我有2个服务： 订单详细信息服务和送货服务 。 I want to have a Gateway endpoint GET /orders/{orderId} that makes a call to Order Details service and then Delivery Service and combine the two to return full Order details with delivery. 我希望有一个网关端点GET / orders / {orderId} ，该端点先调用Order Details服务 ，然后再调用Delivery Service ，然后将两者结合起来以返回完整的订单详细信息。 Is this possible with the routing of Spring cloud or should I make these by hand using something like RestTemplate to make the calls? Spring云的路由是否可行？还是我应该使用RestTemplate之类的工具手动进行调用？
