From 2985d089517a4f83af1cff264d926955f74da2fd Mon Sep 17 00:00:00 2001 From: Daigo 3 Dango Date: Mon, 5 Jun 2017 10:09:29 +0000 Subject: [PATCH] Redirect to streaming_api_base_url (#3579) * Redirect to streaming_api_base_url When Rails receives a request to streaming API, it most likely means that there is another host which is configured to respond to it. This is to redirect clients to that host if `STREAMING_API_BASE_URL` is set as another host. * Use the new Ruby 1.9 hash syntax --- .../api/v1/streaming_controller.rb | 15 ++++++ config/routes.rb | 1 + .../api/v1/streaming_controller_spec.rb | 46 +++++++++++++++++++ 3 files changed, 62 insertions(+) create mode 100644 app/controllers/api/v1/streaming_controller.rb create mode 100644 spec/controllers/api/v1/streaming_controller_spec.rb diff --git a/app/controllers/api/v1/streaming_controller.rb b/app/controllers/api/v1/streaming_controller.rb new file mode 100644 index 000000000..377951472 --- /dev/null +++ b/app/controllers/api/v1/streaming_controller.rb @@ -0,0 +1,15 @@ +# frozen_string_literal: true + +class Api::V1::StreamingController < ApiController + respond_to :json + + def index + if Rails.configuration.x.streaming_api_base_url != request.host + uri = URI.parse(request.url) + uri.host = URI.parse(Rails.configuration.x.streaming_api_base_url).host + redirect_to uri.to_s, status: 301 + else + raise ActiveRecord::RecordNotFound + end + end +end diff --git a/config/routes.rb b/config/routes.rb index 5c1c8e594..7a2286f92 100644 --- a/config/routes.rb +++ b/config/routes.rb @@ -141,6 +141,7 @@ Rails.application.routes.draw do resource :public, only: :show, controller: :public resources :tag, only: :show end + resources :streaming, only: [:index] get '/search', to: 'search#index', as: :search diff --git a/spec/controllers/api/v1/streaming_controller_spec.rb b/spec/controllers/api/v1/streaming_controller_spec.rb new file mode 100644 index 000000000..daf2807e7 --- /dev/null +++ b/spec/controllers/api/v1/streaming_controller_spec.rb @@ -0,0 +1,46 @@ +# frozen_string_literal: true + +require 'rails_helper' + +describe Api::V1::StreamingController do + around(:each) do |example| + before = Rails.configuration.x.streaming_api_base_url + Rails.configuration.x.streaming_api_base_url = Rails.configuration.x.web_domain + example.run + Rails.configuration.x.streaming_api_base_url = before + end + + before(:each) do + request.headers.merge!
