因此，我正在使用Figaro存储我的秘密Twitter和Facebook oauth密钥，以便可以正确地部署到Heroku。我只想确认我做对了。
在我的application.yml（由figaro生成）中：
// Add application configuration variables here, as shown below.
//
// PUSHER_APP_ID: "2954"
// PUSHER_KEY: 7381a978f7dd7f9a1117
// PUSHER_SECRET: abdc3b896a0ffb85d373
// STRIPE_API_KEY: EdAvEPVEC3LuaTg5Q3z6WbDVqZlcBQ8Z
// STRIPE_PUBLIC_KEY: pk_BRgD57O8fHja9HxduJUszhef6jCyS
// note these are arbitrary keys for the stack overflow
FR_FACEBOOK_KEY=1231231233123123
FR_FACEBOOK_SECRET=3123123123123
TWITTER_CONSUMER_KEY=12312312312312
TWITTER_CONSUMER_SECRET=1312312312312
这就是application.yml，然后我只需要运行：
heroku config:add FR_FACEBOOK_KEY=8926 // and so on...
正确？
还是我错过了什么？
提前致谢！
当我运行rake figaro：heroku时，出现此错误：
[new_work]$rake figaro:heroku

最佳答案
请记住使用:而不是=来分隔键和值。您可以使用ENV["KEY_NAME"]从rails应用访问密钥。
但是，在使用Figaro时，您不必按heroku config:add键，只需使用rake figaro:heroku，如此处https://github.com/laserlemon/figaro所述
