使用 Retrofit 和 RxJava 的 Http 请求
Http request with Retrofit and RxJava
我正在请求带有 Retrofit 2 库的 Web 服务 API。我有 API 的 URL 的以下代码：
String ENDPOINT = "https://api.trakt.tv/";
@GET("movies/popular?limit=10&extended=full,images")
public Observable<PopularMoviesResponse> getPopularMovies(@Header("trakt-api-version") String trakt_api_version,
@Header("trakt-api-key") String trakt_api_key,
@Query("page") String page);
我正在使用上面的方法：
public Observable<List<PopularMovies>> fetchPopularMovies(String trakt_api_version,
String trakt_api_key,
String page) {
return movieService
.getPopularMovies(trakt_api_version, trakt_api_key, page)
.concatMap(new Func1<PopularMoviesResponse, Observable<? extends List<PopularMovies>>>() {
@Override
public Observable<? extends List<PopularMovies>> call(final PopularMoviesResponse popularMoviesResponse) {
Log.d("uuuuuu", "oooooo");
return Observable.create(new Observable.OnSubscribe<List<PopularMovies>>() {
@Override
public void call(Subscriber<? super List<PopularMovies>> subscriber) {
Log.d("uuuuuu", "oooooo");
try {
if (subscriber.isUnsubscribed()) return;
subscriber.onNext(popularMoviesResponse.getPopularMovies());
subscriber.onCompleted();
} catch (Exception e) {
subscriber.onError(e);
}
}
});
}
});
}
日志数据显示http状态码为200，okhttp正常记录响应。然而，在第二段代码中，日志没有到达！有什么问题吗？
更新，
这是订阅可观察对象的代码：
public void getPopularMovies(final String page) {
mDataManager.fetchPopularMovies(TraktAPI.TRAKT_API_VERSION.getValue(), TraktAPI.TRAKT_API_KEY.getValue(), page)
.observeOn(AndroidSchedulers.mainThread())
.subscribeOn(Schedulers.io())
.subscribe(new Observer<List<PopularMovies>>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
mMvpView.showEmpty();
}
@Override
public void onNext(List<PopularMovies> popularMoviesList) {
Log.d("onNext", "pppppppppppp");
mMvpView.showListOfPopularMovies(popularMoviesList);
}
});
}
我已经在订阅代码中记录了 onError，我得到了以下堆栈跟踪：

请尝试更改
public Observable<PopularMoviesResponse> getPopularMovies
到
public Observable<List<PopularMovies>> getPopularMovies
Android你的方法那么：
public Observable<List<PopularMovies>> fetchPopularMovies(String trakt_api_version,
String trakt_api_key,
String page) {
return movieService
.getPopularMovies(trakt_api_version, trakt_api_key, page)
}
UPD
只是为了确保您的 POJO 匹配 JSON，您可以使用 that service. In that gist 您可以检查完整结果。

请尝试更改
public Observable<PopularMoviesResponse> getPopularMovies
到
public Observable<List<PopularMovies>> getPopularMovies
Android你的方法那么：
public Observable<List<PopularMovies>> fetchPopularMovies(String trakt_api_version,
String trakt_api_key,
String page) {
return movieService
.getPopularMovies(trakt_api_version, trakt_api_key, page)
}
