夸库斯。使用 Websockets 时握手异常 Next

Question

在尝试使用 Quarkus Websockets Next 客户端连接到 Websocket 服务器时，我遇到了以下异常。从异常消息和源代码中我看到当握手响应状态不是 101 时会引发异常。捕获此异常的指定方法是什么（我想用自定义消息向用户显示它）？ 一般问题是它在主线程之外调用，因此无法以直接的方式捕获它。

Answer 1

我们需要更多信息。您使用

WebSocketConnector

还是

BasicWebSocketConnector

？您使用什么版本的 Quarkus？一般来说，连接器应该收到错误（对于

CompletionException

包裹在

connectAndAwait()

中，或者对于

Uni

返回失败的

connect()

）。
