我正在尝试将 Pusher 插入到我已经很晚的 Rails 应用程序中。客户端工作正常 - 使用 Pusher Event Creator 触发所需的 javascript。但是服务器端不起作用：
在我的通知控制器中使用以下代码创建操作来测试：
Pusher.trigger('private-4','new_message', {:from => "christian", :subject => "hello"})
给出这个错误：
Pusher::AuthenticationError (Unknown auth_key):
app/controllers/notifications_controller.rb:57:in `block in create'
app/controllers/notifications_controller.rb:38:in `create'
（调试控制台中没有出现任何新内容）
我在开发环境中运行它。我已经在我的系统上测试了“推送/通知”示例应用程序，客户端和服务器都可以正常工作。
在 development.rb 中：
# Pusher
require 'pusher'
Pusher.app_id = '{redacted}'
Pusher.key = '{redacted}'
Pusher.secret = '{redacted}'
Pusher.logger = Rails.logger
更新 - 完整的日志输出：
Unknown auth_key (Pusher::AuthenticationError)
