Websocket Ktor CIO wss套接字立即关闭

当使用KTO或CIO ws时，它会按预期工作，但当使用wss时，它会立即关闭。非常感谢您的帮助。我被困了一天了

这是我为wss获取的堆栈跟踪

代码如下：

httpClient.ws(host = "echo.websocket.org") {
  send(Frame.Text("Hello World"))

  for (message in incoming.map { it as? Frame.Text }.filterNotNull()) {
    println(message.readText())
  }
}

httpClient.wss(host = "echo.websocket.org") {
  send(Frame.Text("Hello World"))

  for (message in incoming.map { it as? Frame.Text }.filterNotNull()) {
    println(message.readText())
  }
}

I安全WebSocket出现问题，在ktor

1.3.2

中已修复

我还想指出，

echo.websocket.org

不会关闭连接，因此for循环将永远挂起（期待下一条pong消息）

为了避免这种情况，您可以重写此

for（incoming.map{it as？Frame.Text}.filterNotNull（）中的消息）{
println（message.readText（））
}

作为

val pong=incoming.receive（）作为Frame.Text
println（pong.readText（））

发送第一条消息后，显式调用

close（）

也可以，但目前不支持。我为此单独提交了一份文件：
