Play框架無法連接到WS

Question

我試圖提供一個WebSocket連接到我的Play應用程序，但是即使使用示例代碼我也遇到了問題。 使用websocket回顯頁面，我嘗試發送數據。但是，我甚至無法連接。

我有一個控制器，在那裏我有樣品public WebSocket<String> socket() 在我的路線文件我有GET /socket @controllers.Application.socket()

當使用URL：WS：//本地主機：9001 /插座沒有任何反應 當使用WSS：//本地主機：9001 /套接字，我得到netty錯誤，沒有真正的信息。

我很遺憾地不知道該怎麼做。如果需要，我可以提供更多代碼，這是Play的文檔頁面中的示例代碼。

問題是因爲我在HTTPS中使用了回顯測試。一旦我將其更改爲HTTP一切正常。
