现在的android开发绝大多数都使用okhttp请求数据。
okhttp必须在安装完所有okhttp所需环境文件后才能过使用,分为okhttp.jar和okio.jar,下载地址为:"http://square.github.io/okhttp/"。
okhttp的get请求分为4步:
1.建立okhttp对象
OkHttpClient okhttpclient = new OkHttpClient();2.构造request
Request.Builder buider = new Request.Builder(); Request request = buider.get().url("https://www.imooc.com/").build();
3.将request封装成Call
Call call = okhttpclient.newCall(request);
4.执行Call(异步 ps:此操作不能操作UI)
call.enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { } @Override public void onResponse(Call call, Response response) throws IOException { } });
