如何解决为什么改造从ASP Web服务获取数据太慢
我编写了一个android应用程序，但是它从服务器获取数据的速度太慢 我使用rxjava和改造来获取数据和Web服务已由asp.net编写 请告诉我该怎么办 我已经与邮递员检查过Web服务，它们很好而且很快 请查看我的代码，并告诉我它们有什么问题 这些是我的代码： 片段：
public class HomeFragment extends BaseFragment implements HomeContract.View {
private HomeContract.Presenter presenter;
private SliderView slider;
private TextView txt_homeFragment_showAllNew,txt_homeFragment_showAllTopSelling,txt_homeFragment_showAllHits;
private RecyclerView rv_homeFragment_newProduct,rv_homeFragment_topSelling,rv_homeFragment_hits,rv_homeFragment_specialOffer;

演示者：
public class HomePresenter implements HomeContract.Presenter {
private HomeContract.View view;
private TCommerceDataSource tCommerceDataSource;
private CompositeDisposable compositeDisposable = new CompositeDisposable();
private Context context;
HomePresenter (TCommerceDataSource tCommerceDataSource,Context context){
this.tCommerceDataSource = tCommerceDataSource;
this.context = context;
}
@Override
public void attachView(HomeContract.View view) {
this.view = view;
}
@Override
public void detachView() {
this.view = null;
if (compositeDisposable != null){
compositeDisposable.clear();
}
}
@Override
public void getNewProduct() {
tCommerceDataSource.getListStockNew().subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new SingleObserver<StockListModel>() {
@Override
public void onSubscribe(Disposable d) {
compositeDisposable.add(d);
}
@Override
public void onSuccess(StockListModel productList) {
view.showNewProduct(productList);
view.showTopSellProduct(productList);
}
@Override
public void onError(Throwable e) {
view.showMessage(e.toString());
}
});
}
@Override
public void getHitsProduct() {
tCommerceDataSource.getListStockBestView().subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new SingleObserver<StockListModel>() {
@Override
public void onSubscribe(Disposable d) {
compositeDisposable.add(d);
}
@Override
public void onSuccess(StockListModel stockListModel) {
view.showHitsProduct(stockListModel);
}
@Override
public void onError(Throwable e) {
view.showMessage(e.toString());
}
});
}
@Override
public void getSlider() {
tCommerceDataSource.getSlideImage().subscribeOn(Schedulers.newThread())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new SingleObserver<ItemImageSlider>() {
@Override
public void onSubscribe(Disposable d) {
compositeDisposable.add(d);
}
@Override
public void onSuccess(ItemImageSlider itemImageSlider) {
view.showSlider(itemImageSlider);
}
@Override
public void onError(Throwable e) {
view.showMessage(e.toString());
}
});
}
}
这些是我的Okhttp客户端和拦截器：
OkHttpClient httpClient = new OkHttpClient.Builder()
.connectTimeout(6,TimeUnit.MINUTES)
.readTimeout(6,TimeUnit.MINUTES)
.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request()
.newBuilder()
.build();
return chain.proceed(request);
}
}).build();
return httpClient;
我应该如何使用拦截器？ 我应该改变什么？
解决方法
示例用法（不是答案-仅用于调试）
public class LoginInterceptor extends Interceptor {
private static final String TAG = LoginInterceptor.class.getSimpleName() + " : ";
@Override
public Response intercept(Interceptor.Chain chain) throws IOException {
Request request = chain.request();
long t1 = System.nanoTime();
Log.i(TAG,String.format("Sending request %s on %s%n%s",request.url(),chain.connection(),request.headers()));
Response response = chain.proceed(request);
long t2 = System.nanoTime();
Log.d(TAG,String.format("Received response for %s in %.1fms%n%s",response.request().url(),(t2 - t1) / 1e6d,response.headers()));
return response;
}
并将其添加到客户端
.addNetworkInterceptor（new LoginInterceptor（））
