OkGo 拦截器实现更新token

public class MyApplication extends Application {

public static MyApplication INSTANCE; @Override public void onCreate() { super.onCreate(); INSTANCE = this; OkGo.getInstance().init(this); /** * 加载证书 */
        try { HttpsUtils.SSLParams sslParams = HttpsUtils.getSslSocketFactory(getAssets().open("xxxx.cer")); OkHttpClient builder = new OkHttpClient.Builder() .sslSocketFactory(sslParams.sSLSocketFactory, sslParams.trustManager) .hostnameVerifier(new HostnameVerifier() { @Override public boolean verify(String hostname, SSLSession session) { return true; } }) .addInterceptor(new MyInterceptor()) .build(); OkGo.getInstance().setOkHttpClient(builder); }catch (Exception e){ e.printStackTrace(); } } }
