Kotlin可以成功地執(zhí)行網絡請求。為了實現(xiàn)這一功能,您可以使用多種庫,其中最流行的是Ktor和OkHttp。
build.gradle
文件中:implementation "io.ktor:ktor-client-core:1.6.7"
implementation "io.ktor:ktor-client-cio:1.6.7"
implementation "io.ktor:ktor-client-json:1.6.7"
implementation "io.ktor:ktor-client-json-jvm:1.6.7"
然后,您可以使用以下代碼示例執(zhí)行GET請求:
import io.ktor.client.*
import io.ktor.client.request.*
import io.ktor.client.statement.*
import io.ktor.http.*
suspend fun main() {
val client = HttpClient()
try {
val response: HttpResponse = client.get("https://api.example.com/data")
if (response.status == HttpStatusCode.OK) {
val data = response.readText()
println(data)
} else {
println("請求失敗,狀態(tài)碼:${response.status}")
}
} catch (e: Exception) {
println("請求異常:${e.message}")
} finally {
client.close()
}
}
build.gradle
文件中:implementation "com.squareup.okhttp3:okhttp:4.9.1"
然后,您可以使用以下代碼示例執(zhí)行GET請求:
import okhttp3.OkHttpClient
import okhttp3.Request
import java.io.IOException
fun main() {
val client = OkHttpClient()
val request = Request.Builder().url("https://api.example.com/data").build()
try {
client.newCall(request).execute().use { response ->
if (response.isSuccessful) {
val data = response.body?.string()
println(data)
} else {
println("請求失敗,狀態(tài)碼:${response.code}")
}
}
} catch (e: IOException) {
println("請求異常:${e.message}")
}
}
這些示例展示了如何使用Kotlin執(zhí)行簡單的GET請求。您可以根據(jù)需要修改它們以執(zhí)行其他類型的HTTP請求(如POST、PUT、DELETE等)。
