从命令调用动作 [英] Calling action from command

问题描述

我想通过自定义命令执行操作。前向方法Controller.php类提供了此功能，但我不知道可以从命令文件的execute（）方法访问它

I want to perform an action from a custom command. The forward method Controller.php class provides this function, but I do not know access it from the execute () method of the command file

推荐答案

为控制器提供服务将由于请求堆栈而导致性能开销，因为它随后应返回 HttpResponse 。 Request 范围在命令中不是很有用。

Making the controller a service will result in performance overhead because of the request stack, as it then should return a HttpResponse. The Request scope will not be very usefull in the command.

我建议您从以下位置重构操作将Controller设置为单独的服务类定义，并通过将其设为 ContainerAwareCommand 从控制器和命令中的容器中获取该类。

I'd advise you to refactor the action from the Controller to a separate service class definition, and get that class from the container in both the controller and the command by making it a ContainerAwareCommand.
