Kotlin:
使用基本认证发送 HTTP 请求

import java.net.HttpURLConnection
import java.net.URL
import java.util.Base64

fun sendGetRequestWithBasicAuth(url: String, username: String, password: String) {
    val connection = URL(url).openConnection() as HttpURLConnection
    val auth = Base64.getEncoder().encodeToString("$username:$password".toByteArray())
    
    connection.apply {
        requestMethod = "GET"
        setRequestProperty("Authorization", "Basic $auth")
        inputStream.bufferedReader().use { reader ->
            println(reader.readText())
        }
    }
}

fun main() {
    val url = "https://api.example.com/data"
    val username = "user"
    val password = "pass"
    
    sendGetRequestWithBasicAuth(url, username, password)
}
// Sample Output:
// {"data": "some secure data"}
