提供一下kotlin实现的代码示例

在Kotlin中，我们可以使用`khttp`库或者直接使用HTTP客户端来自定义请求来实现网络通信。这里是一个简单的GET请求示例：

import io.ktor.client.HttpClient
import io.ktor.client.request.get

fun main() {
    val httpClient = HttpClient()
    
    // 发送GET请求到指定URL
    val response = httpClient.get<String>("https://api.example.com/data")

    // 检查响应状态码
    if (response.status == 200) {
        println("Response: ${response.readText()}")
    } else {
        println("Error: ${response.status}")
    }

    // 关闭连接
    httpClient.close()
}

如果你需要发送POST请求并携带JSON数据，可以这样做：

import io.ktor.client.HttpClient
import io.ktor.client.serialization.json
import kotlinx.serialization.encodeToString

data class RequestData(val key: String, val value: Int)

fun main() {
    val httpClient = HttpClient(clientEngine = HttpClient Engine())
    val requestData = RequestData("key", 123)
    val jsonRequest = requestData.encodeToString()

    // 发送POST请求
    val response = httpClient.post<String>("https://api.example.com/submit") {
        addHeader("Content-Type", "application/json")
        body = json(jsonRequest)
    }

    // 处理响应
    if (response.isSuccess) {
        println("Response: $response")
    } else {
        println("Error: ${response.status} - ${response.message}")
    }
    
    httpClient.close()
}

这只是一个基础的例子，实际应用中可能还需要处理错误、添加认证等。
