1. 导入

import okhttp3.OkHttpClient
import okhttp3.Request
import java.io.IOException

2. 创建

// 创建OkHttpClient实例
val client = OkHttpClient()
 
// 创建一个Request对象
val request = Request.Builder()
    .url("http://www.XXXHong.com")
    .build()

3. 异步

// 异步请求
client.newCall(request).enqueue(object : Callback {
    override fun onFailure(call: Call, e: IOException) {
        // 处理请求失败的情况
        println("请求失败：${e.message}")
    }
 
    override fun onResponse(call: Call, response: Response) {
        // 处理请求成功的情况
        if (response.isSuccessful) {
            val responseBody = response.body?.string()
            println("请求成功：$responseBody")
        } else {
            println("请求失败：${response.code} ${response.message}")
        }
    }
})

4. 同步

// 同步请求
try {
    val response = client.newCall(request).execute()
    if (response.isSuccessful) {
        val responseBody = response.body?.string()
        println("请求成功：$responseBody")
    } else {
        println("请求失败：${response.code} ${response.message}")
    }
} catch (e: IOException) {
    println("请求失败：${e.message}")
}
