设计 HTTP 批量请求 [英] Designing HTTP Bulk Request

问题描述

我正在设计一个 REST 批量请求，它将采用以下元素的以下数组:

I am designing a REST Bulk Request that will take following array of following element:

{
    "method": <POST | GET | PATCH>,
    "path": <Relative URL of API to execute>
}

所有这些 Bulk 元素都将在同一服务器上执行 API.有没有办法可以调用调度程序 servlet 在内部执行它而不是调用 API 支持的方法?我还想读取批量请求中每个请求操作的响应并累积将返回的响应.

All these Bulk elements would execute the API on the same server. Is there a way I can call dispatcher servlet to execute this internally rather than calling methods backed by API ? I also want to read response for every request operation in Bulk request and accumulate response that will returned.

目前我正在使用 if elses 执行请求映射工作方式直接调用方法.

Currently I am calling methods directly with if elses doing request mapping style of work.

如果我遗漏了表达我的问题定义的任何细节，请告诉我.请求重定向/转发在我的情况下不起作用，因为我需要控制执行批量请求中的每个操作并收集和累积响应.

Please let me know if I am missing any details on expressing my problem definition. Request redirect/forward wont work in my case as I need to be in control to execute every operation in Bulk request and collect and accumulate response.

我正在使用 Spring Boot MVC

推荐答案

您可以考虑实现虚拟"HttpServletRequest 和 HttpServletResponse.在批量请求控制器中自动装配 DispatcherServlet.

You can consider implementing "dummy" HttpServletRequest and HttpServletResponse. Autowire the DispatcherServlet in your bulk request controller.

在处理批量请求的控制器方法中，在循环处理单个请求时，实例化您自己的 HttpServletRequest 和 HttpServletResponse 实现并调用

In your controller method which handle the bulk request, while looping through the individual request, instantiate your own implementation of HttpServletRequest and HttpServletResponse and call the

dispatcherServlet.service(request, response);

dispatcherServlet.service(request, response);

您可以通过 response.getStatus() 读取响应状态，通过 response.getOutputStream() 或 response.getWriter() 读取内容.请参阅java-printwriter-vs-servletoutputstream/.

You can read the response status via response.getStatus() and content via response.getOutputStream() or response.getWriter(). See java-printwriter-vs-servletoutputstream/.

通过这样做，您不必手动调用控制器方法.

By doing so, you don't have to manually call your controller method manually.

这就是我实现批量请求的方式.

That's how I implemented the bulk requests.
