public class HttpUtil{
 public static void sendOkHttpRequest(String address,okhttp3.Callback callback){
        OkHttpClient client = new OkHttpClient();
        Request request= new Request.Builder()
                .url(address)
                .build();
        client.newCall(request).enqueue(callback);
    }
}

我们在调用sendOhHttpRequest()方法的时候就可以这样写:

HttpUtil.sendOkHttpRequest("http://www.baidu.com",new okhttp3.Callback) throws IOException{
@Override
public void onResponse(Call call,Response response){
//得到服务器返回的具体内容
  String responseData = response.body().string();
}
@Override
public void onFailure(Call call,IOException e){
 //在这里对异常进行处理
}
}
