Play Framework无法连接到WS

Question

我正在尝试提供到我的Play应用程序的WebSocket连接，但是我遇到了问题，即使是示例代码也是如此。使用websocket echo页面，我尝试发送数据。然而，我甚至不能连接。

我有一个控制器，在我的路由文件中有示例public WebSocket<String> socket()，我有GET /socket @controllers.Application.socket()

当使用URL: ws://localhost:9001/socket时没有任何反应而使用wss://localhost:9001/socket时，我得到了没有实际信息的netty错误。

遗憾的是，我不知道该怎么办。如果需要，我可以提供更多代码，这是Play文档页面中的示例代码。

Answer 1

这个问题是因为我使用了HTTPS中的回声测试。当我把它改成HTTP后，一切都正常了。
