kotlin okhttp post请求 例子

简单举例okhttp发送post请求。
比如说发送post请求，API的地址是https://www.abc.com/api/test，参数是username。

首先引用包名

import okhttp3.*
import okhttp3.RequestBody.Companion.toRequestBody

构建post参数和请求

val urlAPI: String = "https://www.abc.com/api/test"

val builder = FormBody.Builder()
builder.add("username",  "彭裤子")
val formBody = builder.build()

val request = Request.Builder()
                .method("POST", formBody)
                .url(urlAPI).build()


val client = OkHttpClient()

client.newCall(request).enqueue(object : Callback {

override fun onResponse(call: Call, response: Response) {
    val result = response.body?.string()
    println("result：" + result)
}

override fun onFailure(call: Call, e: IOException) {
    println("Failed request api :( " + e.message)
}

})
