Answer 1

尝试添加以下行的config/environment.rb文件

Rails.application.routes.default_url_options = { :host => "https://example.herokuapp.com" } 
#=> host you can change your domain

您可以在development.rb，production.rb和test.rb

中单独使用此功能

<强> production.rb

config.action_mailer.default_url_options = { :host => "https://example.herokuapp.com" }

确保在进行更改后重新启动服务器

<强>更新

现在我认为ENV['root_url']引发的问题，你可以改变这个，如下所示

<%= lead_url(@lead, host: 'https://your-domain.com' ) %>

用于测试目的，看看发生了什么，如果它正在工作，那么你可以以正确的方式设置环境变量

对于环境变量，您可以使用Figaro gem，将Figaro添加到Gemfile并捆绑安装：

gem "figaro"

费加罗安装很简单：

bundle exec figaro install
#=> create  config/application.yml

安装后转到config/application.yml并添加这样的网址

root_url: "https://you-domain.com"

然后现在

<%= ENV['root_url'] %>
#=> https://you-domain.com
