推荐答案

Procfile是一种机制，用于声明Heroku平台上应用程序的dynos运行的命令。

Procfile is a mechanism for declaring what commands are run by your application’s dynos on the Heroku platform.

从过程类型和Procfile ，这是一个很好的介绍，但基本上你使用Procfile来告诉Heroku如何运行你的应用程序的各个部分。每行上冒号左边的部分是过程类型;

From Process Types and the Procfile, which is a good introduction, but basically you use the Procfile to tell Heroku how to run various pieces of your app. The part to the left of the colon on each line is the process type; the part on the right is the command to run to start that process.

虽然 web 是特殊的，因为Heroku会将HTTP请求路由到以 web 名称开头的进程。其他进程（如后台工作人员）可以被命名为任何东西，您可以使用Heroku工具带通过引用其名称来启动或停止这些进程。

Process types can be anything, although web is special, as Heroku will route HTTP requests to processes started with the web name. Other processes, such as background workers, can be named anything, and you can use the Heroku toolbelt to start or stop those processes by referring to its name.

因此，在简而言之， worker 是不必要的，除非您想通过用 heroku ps 命令控制进程。

So, in short, worker is not necessary, unless you want to run some other process in the background by controlling process with the heroku ps command.
