在Django视图中执行阻止请求 [英] Performing a blocking request in django view

问题描述

在我的django应用程序中的一种视图中，我需要执行一个相对冗长的网络IO操作.问题是其他请求即使与该请求无关也必须等待该请求完成.我做了一些研究，偶然发现了Celery，但据我了解，它用于执行独立于请求的后台任务.(因此我无法将任务的结果用于对请求的响应)

In one of the views in my django application, I need to perform a relatively lengthy network IO operation. The problem is other requests must wait for this request to be completed even though they have nothing to do with it. I did some research and stumbled upon Celery but as I understand, it is used to perform background tasks independent of the request. (so I can not use the result of the task for the response to the request)

有没有一种方法可以在Django中异步处理视图，以便在网络请求待处理时可以处理其他请求?

Is there a way to process views asynchronously in django so while the network request is pending other requests can be processed?

我忘了提到的是，我的应用程序是使用django rest框架的Web服务.因此，视图的结果是json响应，而不是我以后可以使用AJAX修改的页面.

What I forgot to mention is that my application is a web service using django rest framework. So the result of a view is a json response not a page that I can later modify using AJAX.

推荐答案

通常的解决方案是将任务转移到芹菜上，并在您的视图中返回请稍候"响应.如果需要，则可以使用Ajax调用来定期命中一个视图，该视图将报告响应是否准备就绪，并在响应就绪时进行重定向.

The usual solution here is to offload the task to celery, and return a "please wait" response in your view. If you want, you can then use an Ajax call to periodically hit a view that will report whether the response is ready, and redirect when it is.
