我有一个在Heroku上的Rails应用和一个单独托管在GoDaddy上的WordPress博客。我该如何将RailsApp.com/blog路由到WordPress,并保持它作为应用程序的子目录?
如果您正在使用Rails3.1+ (+Rails4)版本,则需要按照以下步骤进行操作:
首先,在Gemfile中添加gem rack-proxy:
gem "rack-proxy"
然后将proxy.rb文件添加到Rails.root/lib文件夹中,如下所示:
require 'rack/proxy'
class Proxy < Rack::Proxy
def initialize(app)
@app = app
end
def call(env)
original_host = env["HTTP_HOST"]
rewrite_env(env)
if env["HTTP_HOST"] != original_host
perform_request(env)
else
# just regular
@app.call(env)
end
end
def rewrite_env(env)
request = Rack::Request.new(env)
if request.path =~ /^\/blog(\/.*)$/
# enable these code if you set blog as ROOT directory in wordpress folder
# env['REQUEST_PATH'] = '/'
# env['ORIGINAL_FULLPATH'] = '/'
# env['PATH_INFO'] = '/' # set root path request
env['REQUEST_URI'] = 'http://tinle1201.wordpressdomain.com' # your path
env["SERVER_PORT"] = 80
env["HTTP_HOST"] = "tinle1201.wordpressdomain.com" # point to your host
end
env
end
end*
在 config/application.rb 中注册代理到中间件:
require File.expand_path('../boot', __FILE__)
require 'rails/all'
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)
module AdultSavings
class Application < Rails::Application
config.autoload_paths += %W(#{config.root}/lib)
config.middleware.use "Proxy"
# Settings in config/environments/* take precedence over those specified here.
# Application configuration should go into files in config/initializers
# -- all .rb files in that directory are automatically loaded.
# Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
# Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
# config.time_zone = 'Central Time (US & Canada)'
# The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
# config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
# config.i18n.default_locale = :de
end
end*
define('WP_HOME', 'http://tinle1201.wordpressdomain.com/blog');
Rails配置
添加到Gemfile:
gem "rack-reverse-proxy", :require => "rack/reverse_proxy"
use Rack::ReverseProxy do
reverse_proxy(/^\/blog(\/.*)$/,
'http://CHANGEME.herokuapp.com$1',
opts = {:preserve_host => true})
end
match "/blog" => redirect("/blog/")
