Android Studio 看不到 Ktor 序列化器（未找到 class 'User' 的序列化器。）

Question

我正在尝试在我的项目中使用 Ktor。我按照文档中的说明制作了所有内容，但它不起作用

依赖关系：

implementation "io.ktor:ktor-client-core:1.5.4"
implementation "io.ktor:ktor-client-android:1.5.4"
implementation "io.ktor:ktor-client-serialization-jvm:1.5.4"

HTTP客户端和请求：

val client = HttpClient {
    install(JsonFeature){
        serializer = KotlinxSerializer()
    }
    defaultRequest {
        url {
            protocol = URLProtocol.HTTPS
            host = "testtesttest.zapto.org"
        }
    }
}

suspend fun getUsersList() = client.get<User>{
    url("/users/list")
}

用户class：

import com.kepler88d.icthack2app.model.enumerations.UserSpecialization
import kotlinx.serialization.Serializable

@Serializable
data class User(
    val id: Int,
    val password: String,
    val rating: Float,
    val specialization: UserSpecialization,
    val firstName: String,
    val lastName: String,
    val profileDescription: String,
    val githubProfileLink: String,
    val projectIdList: MutableList<Int>,
    val replyIdList: MutableList<Int>,
    val tgId: String,
)

用户专业化class:

import kotlinx.serialization.Serializable

@Serializable
enum class UserSpecialization {
    IOS_DEVELOPER, ANDROID_DEVELOPER, WEB_BACKEND_DEVELOPER, WEB_FRONTEND_DEVELOPER
}

当我尝试将 JSON 反序列化为对象时，它因以下错误而崩溃：

kotlinx.serialization.SerializationException: Serializer for class 'User' is not found.
Mark the class as @Serializable or provide the serializer explicitly.

奇怪的是枚举 class Android studio 认为是可序列化的，但数据 class 不是

enum class data class

Answer 1

解决方案是添加插件

id 'kotlinx-serialization'

Answer 2

我为 Android 做了这个，但它也可能适用于 ktor。首先，将此行添加到构建项目 gradle:

中的 dependencies

classpath "org.jetbrains.kotlin:kotlin-serialization:1.5.21"

还将这些添加到构建应用程序 gradle:

plugins {
    ...
    id 'kotlinx-serialization'
}
dependencies {
    ...
    implementation 'org.jetbrains.kotlinx:kotlinx-serialization-json:1.2.2'
}

请注意版本号可能不同。
