OKhttp使用

OkHttp是一个高效的HTTP客户端,

• 支持HTTP/2，容许全部同一个主机地址的请求共享同一个socket链接
• 链接池减小请求延时
• 缓存响应内容，避免一些彻底重复的请求
• 透明的GZIP压缩减小响应数据的大小  

须要添加依赖

implementation 'com.squareup.okhttp3:okhttp:4.0.0-RC1'
implementation 'com.squareup.okio:okio:2.2.2'

能够右键module打开module设置搜索okhttp依赖添加

public class MainActivity extends AppCompatActivity {

    String url = "http://wwww.baidu.com";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        new Thread(runnable).start();
    }
    Runnable runnable=new Runnable() {
        @Override
        public void run() {
            OkHttpClient okHttpClient = new OkHttpClient();
            final Request request = new Request.Builder()
                    .url(url)
                    .get()//默认就是GET请求，能够不写
                    .build();
            Call call = okHttpClient.newCall(request);
            call.enqueue(new Callback() {
                @Override
                public void onFailure(Call call, IOException e) {
                    Log.d("输出:", "onFailure: ");
                }

                @Override
                public void onResponse(Call call, Response response) throws IOException {
                    Log.d("输出:", "onResponse: " + response.body().string());
                }
            });

        }
    };
    }
