如何在Heroku预览应用程序postdeploy脚本中设置ENV var [英] How to set ENV var in Heroku preview app postdeploy script

问题描述

我想在预览应用程序上设置 HOST env var to $ HEROKU_APP_NAME.herokuapps.com 它似乎不像我可以在 app.json 中执行此操作，因为这是一个计算值。

I want to set the HOST env var to $HEROKU_APP_NAME.herokuapps.com on a preview app. It doesn't look like I can do this in app.json since this is a computed value.

我希望在这样的postdeploy脚本中执行此操作

I was hoping to do it in a "postdeploy" script like this

heroku config:set HOST="`heroku config:get HEROKU_APP_NAME -a neon-dev-pr-520`.herokuapps.com"

，但它希望以Heroku用户身份验证我。唉，这也不行：

but it wants to authenticate me as a Heroku user. Alas, this doesn't work either:

export HOST=$HEROKU_APP_NAME.herokuapps.com

任何建议？

推荐答案

我发现这篇文章，这表明你可以使用Heroku PlatformAPI。

I found this post which suggests that you can use the Heroku PlatformAPI.

在这种情况下，作为Rails Rake任务作为postdeploy运行：

In this case as a Rails Rake task which is run as the postdeploy:

desc 'Bootstrap review app'
task bootstrap: ['db:schema:load', 'db:seed'] do
  heroku = PlatformAPI.connect_oauth(ENV['HEROKU_API_TOKEN'])
  heroku.config_var.update(ENV['HEROKU_APP_NAME'], 'WWW_HOSTNAME' => "#{ENV['HEROKU_APP_NAME']}.herokuapp.com")
end
