Ruby on rails 重定向“重定向到错误路径，路径中有逗号”；http://myapp.com，myapp.com/foo“；

使用rails版本

    rails (5.1.7)
      actioncable (= 5.1.7)
      actionmailer (= 5.1.7)
      actionpack (= 5.1.7)
      actionview (= 5.1.7)
      activejob (= 5.1.7)
      activemodel (= 5.1.7)
      activerecord (= 5.1.7)
      activesupport (= 5.1.7)
      bundler (>= 1.3.0)
      railties (= 5.1.7)
      sprockets-rails (>= 2.0.0)

使用

config/environments/production.rb

  config.app_domain                            = 'myapp.com'
  config.action_mailer.default_url_options     = { host: 'myapp.com', protocol: 'https' }

控制器内操作返回

什么会导致这种行为

更新 在应用@Benj comment后使用

url_options = { host: 'myapp.com', protocol: 'https' }
config.action_mailer.default_url_options = url_options
config.action_controller.default_url_options = url_options
Rails.application.routes.default_url_options = url_options

拥有

Rails.logger.debug("HERE admin_root_url #{admin_root_url}")
Rails.logger.debug("HERE new_session_path #{new_session_path}")

redirect_to admin_root_path

输出

您可以将url选项设置为

config.action\u controller.default\u url\u options

在config/environments/production.rb中：

url_options = { host: 'myapp.com', protocol: 'https' }
config.action_mailer.default_url_options = url_options
config.action_controller.default_url_options = url_options

此外，如果在使用管线帮助器时遇到问题，还可以设置：

Rails.application.routes.default_url_options = url_options

我已经检查了源代码

我已经检查了

请求。带有\u端口的主机\u

，这将导致我

我在一本书中发现了这一点

request.env['HTTP\u X\u FORWARDED\u HOST']

为空，但

request.env['HTTP\u HOST']

为

“myapp.com，myapp.com”

因此，我添加了

proxy\u set\u头X-Forwarded-Host$Host；

至nginx配置
