Pusher不会在Heroku Rails应用程序上触发，但在localhost：3000上可以正常工作

Question

[我正在Ruby on Rails应用程序上学习Pusher，并在用户单击按钮的地方进行设置，它会提交表单以更新对象，然后触发Pusher事件，该事件发送警报并更改所有正在监听的窗口的背景色该频道。

我的站点在本地服务器localhost：3000和Heroku上运行。在localhost：3000上，这就像一种魅力-当我打开在本地和Heroku上运行站点的窗口时，单击本地站点上的按钮，所有窗口都会收到警报并更新背景色。

但是，当我在Heroku上尝试相同的操作时，没有一个窗口会收到警报或更改颜色。我查看了Pusher上的调试控制台，它显示已建立连接，但未显示已发送的API请求：

Subscribed    35329.28868505   Channel:  client-open    23:52:33
Connection    35329.28868505   Origin:   http://testing-pusher.herokuapp.com    23:52:33
Disconnection  35303.28886132  Channels: client-open, Lifetime: 107.70291038s   23:52:32

每Heroku's help page，我已经安装了pusher gem和插件。

这是我的触发器，在我的switches#update中运行：

@switch.update(color: params[:switch][:color])
Pusher['client-open'].trigger('new_message', {:color => @switch.color})

在application.html.erb上运行的侦听器/绑定：

<script type="text/javascript" charset="utf-8">
$(function() {
    Pusher.log = function(message) {
        if (window.console && window.console.log) {
            window.console.log(message);
        }
    };

    var pusher = new Pusher('my_pusher_key'); // This has my actual key in it
    var channel = pusher.subscribe('client-open');
    channel.bind('new_message', function(data) {
        alert("I'm going to change your background color to #"+data.color);
        $("#appended").append("I'm going to change your background color to "+data.color);
        $(".color").css('background-color', '#'+data.color);
});

// Some useful Pusher debug msgs
pusher.connection.bind('connecting', function() {
    $('div#status').text('Connecting to Pusher...');
});

pusher.connection.bind('connected', function() {
    $('div#status').text('Connected to Pusher!');
});
    pusher.connection.bind('failed', function() {
      $('div#status').text('Connection to Pusher failed :(');
    });
    channel.bind('subscription_error', function(status) {
      $('div#status').text('Pusher subscription_error');
    });
  });
</script>

我在同一文件的标题中具有这两个脚本：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script src="http://js.pusherapp.com/2.0/pusher.min.js"></script>

我如何让Pusher在Heroku上正确触发？

编辑：这是Heroku日志。没有错误可以告诉我：

该项目现在在testing-pusher.herokuapp.com上进行。

Answer 1

您在Heroku日志中看到任何错误或消息吗？

而且，您是否在Heroku上尝试了一个简单的测试用例，除了通过Pusher gem发送消息外，什么也没有做？

Answer 2

我认为您需要更改Pusher应用程序凭据。
