Ruby on rails TypeError（没有将nil隐式转换为字符串）Rails在生产环境中设计jwt gem

将ENV['designe_JWT_SECRET_KEY']返回生产控制台中的秘密密钥

designe_JWT_SECRET_密钥通过Centos上的导出命令设置

designe.rb文件

 config.jwt do |jwt|
    jwt.secret = ENV['DEVISE_JWT_SECRET_KEY']
    jwt.dispatch_requests = [
      ['POST', %r{^/users/sign_in.json$}]
    ]
    jwt.revocation_requests = [
      ['DELETE', %r{^/logout$}]
    ]
    jwt.expiration_time = 1.day.to_i
  end

在登录请求中获取此错误

似乎，我错过了生产块中的gem'dotenv rails'

只需两步即可修复

gem 'dotenv-rails', :groups => [:development, :test, :production]

加
