ActionController :: RoutingError沒有與“ / cloudfoundryapplication”匹配的[GET]和[OPTION]路由

Question

我在Pivotal Web服務上使用Puma運行Rails 5.1.3。 自從Rails 4升級到此版本后，我看到以下錯誤出現在日志中：

1. ActionController::RoutingError (No route matches [GET] "/cloudfoundryapplication")
2. ActionController::RoutingError (No route matches [OPTION] "/cloudfoundryapplication")

我在Pivotal的“ / cloudfoundryapplication”上找不到任何詳細信息，但是由於我認為它是一個外部應用程序，因此可能與跨域資源共享（CORS）有關。 然后，我使用“ rack-cors” gem嘗試解決此問題。 結果是[OPTION]錯誤消失了，但[GET]錯誤消失了。

這是我的config / application.rb：

require_relative 'boot'

require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
require 'pdfkit'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.

Bundler.require(*Rails.groups)

module MyFaro
  class Application < Rails::Application
    # Initialize configuration defaults for originally generated Rails version.
    config.load_defaults 5.1

    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.

Answer 1

我從Pivotal支持團隊得到了答復。

Pivotal Web Services的Apps Manager使用/ cloudfoundryapplication端點作為Spring Boot Actuator集成的根。 當您在Apps Manager UI中查看該應用程序時，它將為該應用程序調用此端點，無論您是否已為Apps Manager配置了Spring Boot Actuator端點。

因此，對於不使用Spring Boot Actuator端點的應用程序，這些錯誤僅在使用Apps Manager GUI時出現。

它就像冰箱里的薛定ers的光貓：如果不看，就不會出現錯誤。 我通過CLI檢查了日志，實際上根本沒有任何錯誤。

Answer 2

從應用程序的config/routes.rb借一行：

match '/cloudfoundryapplication', to: proc { [200, {}, ['']] }, via: %i[get options]
