非法「仲的WebSocket協議」標題：輸入無效「意向書」，預計仲的WebSocket協議

Question

我想對Kubernetes WebSocket的API連接，但我收到此錯誤信息：

java.lang.IllegalStateException: Message failed with status code 400 Bad Request; Error info: ErrorInfo(Illegal 'sec-websocket-protocol' header: Invalid input 'EOI', expected sec-websocket-protocol (line 1, column 1), 
^)

    at java.util.concurrent.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:157) 

我必須缺少一些配置，你知道這是從哪裏來的？

乾杯

挺過來了定義subprotocol到channel.k8s.io：

WebSocketRequest(
    uri, 
    extraHeaders = List(token), 
    subprotocol = Option("channel.k8s.io") 
)
