我创建了一个类来获取刷新令牌，如果该令牌在任何时候都过期了。 在进行其余的API调用之前，请始终先调用此类。
这是我的课程，
import android.content.Context;
import com.epic.ssb.data.TokenModel;
import com.epic.ssb.security.LogoutProcess;
import com.epic.ssb.security.TokenIdentifier;
import com.epic.ssb.util.Constant;
import java.io.IOException;
import java.net.HttpURLConnection;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;
import okhttp3.Interceptor;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import retrofit2.Call;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
public class RefreshTokenInterceptor implements Interceptor {
private Lock lock = new ReentrantLock();
Context ctx;
public RefreshTokenInterceptor(Context context){
this.ctx = context;
}
@Override
public Response intercept(Chain chain) throws IOException {
chain.withConnectTimeout( 45, TimeUnit.SECONDS);
chain.withReadTimeout(45,TimeUnit.SECONDS);
chain.withWriteTimeout(45,TimeUnit.SECONDS);
Request request = chain.request();
Response response = chain.proceed(request);
if (response.code() == HttpURLConnection.HTTP_UNAUTHORIZED) {
if (lock.tryLock()) {
try {
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request original = chain.request();
Request request = original.newBuilder()
.header("Content-Type", "application/json")
.header("X-Requested-With", "XMLHttpRequest")
.header("X-Authorization", "Bearer " + TokenIdentifier.getREFRESHTOKEN())
.method(original.method(), original.body())
.build();
return chain.proceed(request);
}
});
OkHttpClient client = httpClient.build();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constant.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.build();
ApiService apiService = retrofit.create(ApiService.class);
Call<TokenModel> call = apiService.getTokenFromRefreshToken();
retrofit2.Response<TokenModel> response1 = call.execute();
if(response.body()!=null){
TokenModel tokenModel = response1.body();
TokenIdentifier.setTOKEN(tokenModel.getToken());
}
Request newRequest = recreateRequestWithNewAccessToken(chain);
return chain.proceed(newRequest);
} catch (Exception ex) {
LogoutProcess.logout(ctx);
return response;
} finally {
lock.unlock();
}
} else {
lock.lock();
lock.unlock();
Request newRequest = recreateRequestWithNewAccessToken(chain);
return chain.proceed(newRequest);
}
} else {
return response;
}
}
private Request recreateRequestWithNewAccessToken(Chain chain) {
String freshAccessToken = TokenIdentifier.getTOKEN();
return chain.request().newBuilder()
.header("Content-Type", "application/json")
.header("X-Requested-With", "XMLHttpRequest")
.header("X-Authorization", "Bearer " + freshAccessToken)
.method(chain.request().method(), chain.request().body())
.build();
}
}
注意：如果当前令牌已过期，则该类用于获取新令牌。
然后我随机访问了上面的类的以下异常，

正如我在文章顶部提到的那样，这用于安全的Rest API调用。不适用于未经授权的Rest API调用。
为什么这是随机发生的？我应该添加更多步骤吗？
