OKhttp使用

OkHttp是一個高效的HTTP客戶端,

• 支持HTTP/2，容許全部同一個主機地址的請求共享同一個socket鏈接
• 鏈接池減小請求延時
• 緩存響應內容，避免一些徹底重複的請求
• 透明的GZIP壓縮減小響應數據的大小  

須要添加依賴

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

能夠右鍵module打開module設置搜索okhttp依賴添加

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()//默認就是GET請求，能夠不寫
                    .build();
            Call call = okHttpClient.newCall(request);
            call.enqueue(new Callback() {
                @Override
                public void onFailure(Call call, IOException e) {
                    Log.d("輸出:", "onFailure: ");
                }

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

        }
    };
    }
