Websocket握手期間的Rails ActionCable錯誤

我試圖用Rails 5 ActionCable構建一個消息應用程序，但我在JS控制檯中得到了上述錯誤。Websocket握手期間的Rails ActionCable錯誤

ws://localhost:3002/cable' failed: Error during WebSocket handshake: Unexpected response code: 404

我使用Redis的和Puma的寶石。

我有運行7937:M 24 Jul 18:20:53.379 * The server is now ready to accept connections on port 6379

我開始與彪馬Rails的服務器Redis的服務器：（？這是甚至要求）rails s Puma -p 3002

config/cable.yml看起來像這樣...

development: 
    adapter: redis 
    url: redis://localhost:6379 

test: 
    adapter: async 

production: 
    adapter: redis 
    url: redis://localhost:6379/1

當我輸入rails c並執行廣播：

2.2.4 :003 > ActionCable.server.broadcast("messages:1", text: "test") 
[ActionCable] Broadcasting to messages:1: {:text=>"test"} 
=> 0

...你可以看到它返回0，所以它失敗。和控制檯錯誤消息看起來像......

WebSocket connection to 'ws://localhost:3002/cable' failed: WebSocket is closed before the connection is established.

我是個初學者，當談到NGINX。這是NGINX的問題嗎？如果是這樣，我該如何解決它？我是否在/usr/local/etc/nginx/中重新配置我的nginx.conf文件？目前，它看起來像這樣...

SOLUTION

請確保您有

<%= action_cable_meta_tag %>內application.html.erb

此外，

config.action_cable.url = "ws://localhost:3000/cable"內config/environments/development.rb

把這個在您的環境配置文件

config.action_cable.allowed_request_origins = [/http:\/\/*/, /https:\/\/*/]
