我找不到faye.js： 顯然，參考http://localhost:9292/faye.js無法訪問。

我試圖找到faye.js沒有成功：

https://pacific-savannah-8641.herokuapp.com/faye.js
https://pacific-savannah-8641.herokuapp.com/faye
http://pacific-savannah-8641.herokuapp.com/faye

... http://pacific-savannah-8641.herokuapp.com:9292 ...

問題：

我應該如何替換Heroku上的參考文獻http://localhost:9292/faye以便它可以正常工作？

Answer 1

我找到了解決方案。
要將Faye與Heroku一起使用，無需添加額外的dynos（即免費），您應該將Faye作爲中間件安裝到您的應用程序中。
關鍵是要在應用程序中添加特定行。RB：

require File.expand_path('../boot', __FILE__) 

require 'rails/all' 
require 'net/http' 

Bundler.require(*Rails.groups) 

module Helpdesk 
    class Application < Rails::Application 
    config.middleware.delete Rack::Lock 
    config.middleware.use FayeRails::Middleware, mount: '/faye', :timeout => 25 
    end 
end 

此外，你應該添加faye-rails寶石：

gem 'faye-rails', '~> 2.0' 

的application.js應看：

//= require jquery 
//= require jquery.turbolinks 
//= require jquery_ujs 
//= require jquery.remotipart 
//= require turbolinks 
//= require faye 
//= require_tree . 

然後，我創建應用程序/資產/javascripts/realtime.js.coffee來定義我將如何處理實時消息M服務器：

window.client = new Faye.Client('/faye') 

jQuery -> 
    client.subscribe '/comments', (payload) -> 
    $('.ticket-' + payload.token + ' .no-posts').remove() 

    $('<div></div>') 
     .css({'backgroundColor' : '#ff9f5f'}) 
     .prependTo('.ticket-' + payload.token + ' .posts') 
     .hide() 
     .append(payload.message) 
     .fadeIn('slow') 
     .css({transition: 'background-color 3s ease-in-out', "background-color": "white"}) 

最後，這裏是我發佈一條消息給所有用戶應用程序/視圖/職位/ create.js.coffee：

publisher = client.publish('/comments', { 
    message: '<%= j render @post %>', 
    token: '<%= @ticket.token %>' 
}); 

Procfile應與內容：

web: bundle exec rails server thin -p $PORT -e $RACK_ENV
