【问题描述】:
我在 Ruby on Rails 应用程序上学习 Pusher,并在用户单击按钮时设置它,它提交表单以更新对象,然后触发 Pusher 事件发送警报并更改所有窗口监听的背景颜色在那个频道上。
我的站点在我的本地服务器 localhost:3000 和 Heroku 上运行。在 localhost:3000 上,这就像一个魅力 - 当我打开在本地和 Heroku 上运行该站点的窗口时,我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颜色。
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
根据Heroku's help page,我已经安装了 pusher gem 和插件。
这是在我的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 上运行的监听器/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>
我在同一个文件的头部有这两个脚本:
<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:这里是 Heroku 日志。没有我能说出的错误:
