在應用程序中的所有請求中，如果發生錯誤，需要執行某些操作。 我不想在每個請求中手動處理此操作。有錯誤401在所有請求中動作
是否可以在OkHttp級別解決此問題，以便它立即適用於所有請求？
改造和OkHttp類：
public class RestApi {
public final User user;
private PreferenceHelper preferenceHelper;
public static final String TAG = "RestApi: ";
@Inject
public RestApi(PreferenceHelper preferenceHelper) {
this.preferenceHelper = preferenceHelper;
TokenAppendingHeaderInterceptor tokenInterceptor = new TokenAppendingHeaderInterceptor();
HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(interceptor)
.addInterceptor(tokenInterceptor)
.connectTimeout(10, TimeUnit.SECONDS)
.writeTimeout(10, TimeUnit.SECONDS)
.readTimeout(30, TimeUnit.SECONDS)
.build();
Retrofit retrofit = new Retrofit.Builder().baseUrl(Const.Url.API)
.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
user = retrofit.create(User.class);
}
public class TokenAppendingHeaderInterceptor implements Interceptor {
@Override
public okhttp3.Response intercept(Chain chain) throws IOException {
Request request = chain.request();
String token = preferenceHelper.getToken();
Request newRequest = request.newBuilder()
.addHeader(Const.Url.COOKIE, token)
.build();
return chain.proceed(newRequest);
}
}
public String getCookiesFromResponse(Response response) {
String cookies = "";
List<String> listCookies;
try {
listCookies = response.headers().toMultimap().get("Set-COOKIE");
cookies = CookieHelper.getStringCookies(listCookies);
} catch (NullPointerException e) {
Log.d(TAG, "getCookiesFromResponse: BITRIX can't send cookies");
} finally {
return cookies;
}
}
}
