okHttp的封装类（kotlin）

先贴工具类的代码

object HttpUtil {
    //这是Get请求
    fun sendOkHttpGetRequest(address:String, callback: okhttp3.Callback){
        val client= OkHttpClient()
        val request= Request.Builder().url(address).build()
     //必须调用enqueue方法，异步网络请求
        client.newCall(request).enqueue(callback)
    }
    //这是Post请求
    fun sendOkHttpPostRequest(address: String, requestBody: RequestBody, callback:okhttp3.Callback){
        val client=OkHttpClient()
        val request=Request.Builder().url(address).post(requestBody).build()
    //必须调用enqueue方法，异步网络请求
        client.newCall(request).enqueue(callback)
    }
}

需要使用工具类的时候就HttpUtil.fun()

 HttpUtil.sendOkHttpGetRequest("https://wanandroid.com/user_article/list/$curPage/json",
            object : Callback {
                override fun onFailure(call: Call, e: IOException) {

                }

                override fun onResponse(call: Call, response: Response) {
                    //网络请求成功后，解析json数据
                    val responseData = response.body?.string()
                    //调用方法刷新recycleView数据，但注意在此函数内是子线程不能直接更新ui
                    recycleViewData(responseData)
                }
            })

 val username = mEdUsername.text.toString()
        val password = mEdPassword.text.toString()
        //Post请求需要先bulid requestBody
        val requestBody = FormBody.Builder()
            .add("username", username)
            .add("password", password)
            .build()
        HttpUtil.sendOkHttpPostRequest(
            "https://www.wanandroid.com/user/login",
            requestBody,
            object : Callback {
                override fun onFailure(call: Call, e: IOException) {

                }

                override fun onResponse(call: Call, response: Response) {
                    //网络请求成功后，解析json数据
                    val responseData = response.body?.string()
                }
            })
