okHttpUtils简洁版

public class OkHttpUtils {
private Handler handler = new Handler();
public Handler getHandler(){
return handler;
}
//单例
private static OkHttpUtils okHttpUtils = new OkHttpUtils();
private OkHttpUtils(){};
public static OkHttpUtils getInstance(){
return okHttpUtils;
}

private OkHttpClient client;
private void initOkHttpClient(){
if(client == null){
client = new OkHttpClient.Builder().build();
}
}

//公用的get请求方法  完成的功能不确定
public void doGet(String url, Callback callback){
initOkHttpClient();
Request request = new Request.Builder().url(url).build();
Call call = client.newCall(request);
call.enqueue(callback);
}

}
