Question

我正在使用Ruby on Rails应用程序学习Pusher并将其设置为用户单击按钮的位置，它提交表单以更新对象，然后触发发送警报的Pusher事件并更改所有窗口监听的背景颜色在那个频道上。

我的网站在本地服务器localhost：3000和Heroku上运行。在localhost：3000上，这就像一个魅力 - 当我打开Windows在本地和Heroku上运行网站时，我点击本地站点上的按钮，所有窗口都会收到警报并更新背景颜色。

但是，当我在Heroku上尝试同样的事情时，没有一个窗口收到警报或改变颜色。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

Per Heroku's help page，我已经安装了推送宝石和插件。

这是我在switches#update中运行的触发器：

@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>

我在同一个文件的标题中有这两个脚本：

<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>

如何让Pusher在Heroku上正确触发？

编辑：这是Heroku日志。没错，我可以说：

项目现在正在测试--pusher.herokuapp.com。

Answer 1

您是否在Heroku日志中看到任何错误或消息？

另外，您是否尝试过Heroku上的一个简单的测试用例除了通过Pusher gem发送消息之外什么都不做？

Answer 2

我认为您需要更改Pusher应用凭据。

创建Pusher应用程序时，可以选择代表本地区域群集的群集。例如，“ ap3”表示亚太地区（东京），“ eu”表示“欧洲”。

因此，最好在部署到服务器时更改Pusher应用。

Answer 3

演出迟到了，但如果其他人遇到这个...... 对我来说，我不得不从我的配置中删除这些

const pusher = new Pusher({
  appId: 'APP_ID',
  key: 'APP_KEY',
  secret: process.env.PUSHER_SECRET,
  cluster: 'us2',
  // these two were causing pusher.trigger to not work on deployed server
  // useTLS: true
  // encrypted: true
})

Pusher没有在Heroku Rails应用程序上触发，但在localhost：3000上运行正常
