如何对应用程序保密? [英] How to keep the app secret a secret?

问题描述

每个新的 Play 应用都会在其配置文件中生成一个新的应用机密.

Every new Play app gets a new application secret generated into its config file.

application.secret=asdfadsfdasf

我正在开发一个将部署在 Heroku 上的开源应用程序.我如何将应用保密(例如，不要将其提交到源代码管理中)?

I'm developing an open source app that will be deployed on Heroku. How can I keep the app secret a secret (e.g. no commit it into source control)?

应用机密究竟在哪里使用?也许出于我有限的目的，我真的不必保密?

Where exactly is the app secret used? Perhaps for my limited purposes I don't really have to keep it a secret?

推荐答案

您可以将机密外部化为环境变量.

You can externalize the secret as an environment variable.

在conf/application.conf中简单替换

application.secret=abc123...

与

application.secret=${APP_SECRET}

然后在 Heroku 中设置这个配置变量:

and then set this config var in Heroku with:

$ heroku config:add APP_SECRET=abc123...

现在您可以在每个应用的基础上管理机密，避免将它们签入版本控制.

Now you can manage secrets on a per-app basis and avoid checking them into version control.
