import java.net.URL
import java.nio.charset.StandardCharsets

fun main() {
    val url = URL("https://example.com/api/endpoint") // 替换为实际的API地址
    val requestBody = "param1=value1&param2=value2" // 替换为实际的请求体参数

    val connection = url.openConnection() as HttpURLConnection
    connection.requestMethod = "POST"
    connection.doOutput = true

    val outputStream = connection.outputStream
    outputStream.write(requestBody.toByteArray(StandardCharsets.UTF_8))
    outputStream.flush()
    outputStream.close()

    val responseCode = connection.responseCode
    val response = BufferedReader(InputStreamReader(connection.inputStream))
        .use { reader -> reader.readText() }

    println("Response Code: $responseCode")
    println("Response Body: $response")

    connection.disconnect()
