Intellij Idea 插件开发中的 ktor 客户端问题？

问题描述 投票：0回答：2

我正在为 IntelliJ Idea 开发一个插件 我想用Ktor Client来使用

websocket
功能

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

当我发送 websocket 请求时

client.webSocket(...)

这个异常会被抛出

我还测试了 ktor 服务器。它也给我同样的例外！ 我的问题是

  • 在创意插件中使用
    ktor
    是否有效？
  • 如果没问题，那么我必须做些什么来解决这个问题？

我用过这些版本

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

这是我完整的 build.gradle.kts

plugins {
    id("java")
    id("org.jetbrains.kotlin.jvm") version "1.8.0"
    id("org.jetbrains.intellij") version "1.13.1"
}

group = "com.example"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
}

// Configure Gradle IntelliJ Plugin
// Read more: https://plugins.jetbrains.com/docs/intellij/tools-gradle-intellij-plugin.html
intellij {
    version.set("2022.1.4")
    type.set("IC") // Target IDE Platform

    plugins.set(listOf(/* Plugin Dependencies */))
}


dependencies {
    val ktorVersion = "2.2.2"
    implementation("io.ktor:ktor-client-core:$ktorVersion")
    implementation("io.ktor:ktor-client-cio:$ktorVersion")
    implementation("io.ktor:ktor-client-websockets:$ktorVersion")
}

tasks {
    // Set the JVM compatibility versions
    withType<JavaCompile> {
        sourceCompatibility = "11"
        targetCompatibility = "11"
    }
    withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
        kotlinOptions.jvmTarget = "11"
    }

    patchPluginXml {
        sinceBuild.set("221")
        untilBuild.set("231.*")
    }

    signPlugin {
        certificateChain.set(System.getenv("CERTIFICATE_CHAIN"))
        privateKey.set(System.getenv("PRIVATE_KEY"))
        password.set(System.getenv("PRIVATE_KEY_PASSWORD"))
    }

    publishPlugin {
        token.set(System.getenv("PUBLISH_TOKEN"))
    }
}
更新：

似乎当我添加 ktor 依赖时

org.slf4j.LoggerFactory.getILoggerFactory()

即使我根本不使用 ktor，这段代码也会抛出异常！

更新：

我临时加上这个

configurations.all { 
    exclude("org.slf4j", "slf4j-api")
}

build.gradle.kts 并解决了我的问题，但我不知道它是否实用但至少有效！

java kotlin intellij-plugin ktor

我认为可以在idea插件中使用ktor客户端。

我能够在插件内运行 ktor 客户端 websocket 没有任何问题，它读取并记录传入的消息这是我的代码：


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")
}

根据您的日志

io.ktor.server.engine.ApplicationEngineEnvironmentBuilder
，您尝试使用 ktor 服务器模块 由于缺少设置而崩溃。

根据您的问题，您确实需要客户。

你也错过了引擎，我用的是СIO

val ktorClient = HttpClient(CIO) {...}

另见：

设置ktor websocket客户端

同样的问题，下面的 gradle 配置

dependencies {
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-swing:1.6.4")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.6.4")
    implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.8.21")

    implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.5.0")
    implementation("io.ktor:ktor-serialization-kotlinx-json:2.3.0")
    implementation("io.ktor:ktor-serialization-jvm:2.3.0")
    implementation("io.ktor:ktor-client-cio:2.3.0")
    implementation("io.ktor:ktor-client-core:2.3.0")
    implementation("io.ktor:ktor-client-auth:2.3.0")
    implementation("io.ktor:ktor-client-content-negotiation:2.3.0")
}

并由

修复 
configurations.all {
    exclude("org.slf4j", "slf4j-api")
}
