无法弄清楚为什么会这样。我的调用不会触发任何一个rx回调(onCompleted(),onError(),onNext())。我收到的唯一的东西是这个okhttp输出:
D/OkHttp: --> GET https://api.privatbank.ua/p24api/exchange_rates?json=true&date=20.11.2016 http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: java.io.IOException: Canceled
改造模块:
@Module
public class RestModule {
@Provides
@Singleton
public HttpLoggingInterceptor providesHttpLogginInterceptor() {
return new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY);
}
@Provides
@Singleton
public OkHttpClient providesOkHttpClient(@NonNull HttpLoggingInterceptor loggingInterceptor) {
return new OkHttpClient.Builder()
.addInterceptor(loggingInterceptor)
.connectTimeout(ConstantsManager.CONNECTION_TIME_OUT, TimeUnit.SECONDS)
.readTimeout(ConstantsManager.READ_TIME_OUT, TimeUnit.SECONDS)
.build();
}
@Provides
@Singleton
public Gson providesGson() {
return new GsonBuilder().create();
}
@Provides
@Singleton
public Retrofit providesRetrofit(@NonNull OkHttpClient okHttpClient, @NonNull Gson gson) {
return new Retrofit.Builder()
.baseUrl(ConstantsManager.BASE_URL)
.client(okHttpClient)
.addConverterFactory(SimpleXmlConverterFactory.create())
.addConverterFactory(GsonConverterFactory.create(gson))
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.build();
}
@Provides
@Singleton
public PrivatbankApi providesPrivatbankApi(@NonNull Retrofit retrofit) {
return retrofit.create(PrivatbankApi.class);
}
}
API接口:
public interface PrivatbankApi {
@GET
Observable<CurrentRates> loadCurrentRates(@NonNull @Url String url);
@GET("exchange_rates")
Observable<DateRates> loadDateRates(@NonNull @Query("json") Boolean json, @NonNull @Query("date") String date);
}
订阅:
subscription = dataManager.loadDateRates(date)
.subscribeOn(Schedulers.io())
.doAfterTerminate(() -> {
})
.subscribe(dateRates -> {
// My code here...
}, throwable -> {
Timber.e(throwable, "Error while loading data occurred!");
});
顺便说一下,两个调用都会出现同样的错误:
D/OkHttp: --> GET https://privat24.privatbank.ua/p24/accountorder?oper=prp&PUREXML&apicour&country=ua http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: java.io.IOException: Canceled
D/OkHttp: --> GET https://api.privatbank.ua/p24api/exchange_rates?json=true&date=20.11.2016 http/1.1
D/OkHttp: --> END GET
D/OkHttp: <-- HTTP FAILED: java.io.IOException: Canceled

如果用户取消请求,则抛出该异常。使用RxJavaCallAdapterFactory
时,如果在呼叫完成之前取消订阅,则会发生这种情况。所以我想在你做完电话后的某个时刻,你会subscription.unsubscribe()
取消基础请求。

感谢@Kiskae。这给了我正确的提示。在我的情况下,我使用了CompositeSubscription并在其他方法取消订阅后添加了订阅。
/**
* Adds a new {@link Subscription} to this {@code CompositeSubscription} if the
* {@code CompositeSubscription} is not yet unsubscribed. If the {@code CompositeSubscription} <em>is</em>
* unsubscribed, {@code add} will indicate this by explicitly unsubscribing the new {@code Subscription} as
* well.
*
* @param s
* the {@link Subscription} to add
*/

对我有用的是更换不推荐使用的呼叫适配器:
implementation 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'
具有:
implementation 'com.squareup.retrofit2:adapter-rxjava2:2.9.0'
这帮助我解决了这个问题,每次都会调用onError()。 有关更多信息:https://github.com/JakeWharton/retrofit2-rxjava2-adapter
答案 3 :(得分:0)
我遇到了同样的问题,但在我的情况下,当两个请求在同一CompositeDisposable
中进行订阅时,其中一个被取消。我的意思是那两个请求是并行完成的。
