我正在为IntelliJ Idea开发一个插件我想使用Ktor客户端来使用websocket功能

val client = HttpClient(CIO) {
    install(WebSockets)
}

当我发送WebSocket请求时

client.webSocket(...)

将引发此异常

我也测试了ktor服务器。它也给予了我同样的异常！我的问题是

  • 在idea插件中使用ktor是否有效？
  • 如果可以的话，我该怎么做才能解决这个问题？

我用了这些版本

kotlinVersion = "1.8.0"
ideaPluginVersion = "1.13.1"
ktorVersion = "2.2.2"
更新：

当我添加ktor依赖项时

org.slf4j.LoggerFactory.getILoggerFactory()

即使我根本不使用ktor，这段代码也会抛出那个异常！

在我看来，在idea插件中使用ktor客户端是可能的。
我能够运行插件内的ktor客户端WebSocket没有任何问题，它读取和记录传入的消息这里是我的代码：

val ktorClient = HttpClient(CIO) {
    install(WebSockets)
}

class PluginAction : DumbAwareAction() {

    override fun actionPerformed(event: AnActionEvent) {

        CoroutineScope(SupervisorJob() + Dispatchers.IO).launch {

            ktorClient.webSocket(
                method = HttpMethod.Get,
                host = "localhost",
                path = "/path",
            ) {
                while (true) {
                    val incoming = (incoming.receive() as Frame.Text).readText()
                    thisLogger().info("incoming: $incoming")
                }
            }
        }
        ktorClient.close()
    }
}

build.gradle.kts:

val ktorVersion = "2.2.2"

dependencies {
    implementation("io.ktor:ktor-client-core:$ktorVersion")
    implementation("io.ktor:ktor-client-cio:$ktorVersion")
    implementation("io.ktor:ktor-client-websockets:$ktorVersion")
}

根据日志io.ktor.server.engine.ApplicationEngineEnvironmentBuilder判断，您尝试使用由于缺少设置而崩溃的ktor服务器模块。
基于你的问题，你需要的正是客户。
你也错过了引擎，我用СIO
val ktorClient = HttpClient(CIO) {...}
