Question

我有一个我在Kotlin + MVP architecture开发的Android项目。它在项目中总共有30个API调用，但有时会从任何一个API中随机抛出套接字超时错误。我不知道在服务器或API或Kotlin-MVP或Rx2AndroidNetworking中是否存在问题？

下面我将向您展示在Kotlin + MVP中调用产品列表Web API调用。

我在iOS中开发的这个项目并没有抛出这个错误，所以它在服务器或API开发上没有错误。我认为这个问题发生在Rx2AndroidNetworking库中。

过去有没有人有任何想法或遇到过这个问题？

ProductInteractor.kt

class ProductInteractor @Inject internal constructor(apiHelper: ApiHelper, preferenceHelper: PreferenceHelper) : BaseInteractor(apiHelper = apiHelper, preferenceHelper = preferenceHelper), ProductMVPInteractor {

override fun getProductList(pagingAndSortingInfo: PagingAndSortingInfo?, searchBy: String, categoryIds: String) =
        apiHelper.performProductListApiCall(pagingAndSortingInfo, searchBy, categoryIds)
}

ProductPresenter.kt（it.showError(t!!.message!!)行抛出套接字超时Toast消息）

class ProductPresenter<V : ProductGridMVPView, I : ProductMVPInteractor> @Inject internal constructor(interator: I, schedulerProvider: SchedulerProvider, compositeDisposable: CompositeDisposable) : BasePresenter<V, I>(interactor = interator, schedulerProvider = schedulerProvider, compositeDisposable = compositeDisposable), ProductMVPPresenter<V, I> {
override fun onViewPrepared(pageNumber: Long?, categoryIds: String?) {

    getView()?.showProgress()
    interactor?.let {
        val pagingAndSortingInfo = PagingAndSortingInfo(AppConstants.PAGE_SIZE.toLong(),
                pageNumber,
                0,
                true,
                true,
                "DisplayOrder",
                AppConstants.SortDirection.Ascending.type)
        var disposable = it.getProductList(pagingAndSortingInfo, "", categoryIds.toString())
                .compose(schedulerProvider.ioToMainObservableScheduler())
                .subscribe ({ productResponse ->
                    getView()?.let {
                        it.hideProgress();
                        var totalRecords: Long? = 0;
                        var currentPage: Long? = 0;
                        var isPagingRequired: Boolean? = false;
                        totalRecords = productResponse.pagingAndSortingInfo!!.totalRecord;
                        currentPage = productResponse.pagingAndSortingInfo!!.pageNumber;
                        isPagingRequired = productResponse.pagingAndSortingInfo!!.isPagingRequired;
                        it.displayProductList(productResponse.productItems, totalRecords, currentPage, isPagingRequired);
                    }
                },{
                    t: Throwable? ->  getView()?.let {
                    it.hideProgress()
                    it.showError(t!!.message!!)
                }
                })
        addSubscription(disposable)
    }
}
}

ProductGridFragment.kt（我在我的产品片段onViewCreated中调用presenter类如下所示。）

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    presenter.onAttach(this)
    super.onViewCreated(view, savedInstanceState)

    srl_product.setOnRefreshListener(object : SwipeRefreshLayout.OnRefreshListener {

        override fun onRefresh() {
            productAdapter.clearData()
            setPageNumber(1);
            setCategoryIds("");
            presenter.onViewPrepared(getPageNumber(), getCategoryIds());
            srl_product.isRefreshing = false;
        }

    })
}

performProductListApiCall Function（在Interactor类中调用此函数）

override fun performProductListApiCall(request: PagingAndSortingInfo?, searchBy: String?, categoryIds: String?): Observable<ProductResponse> =
        Rx2AndroidNetworking.post(ApiEndPoint.ENDPOINT_PRODUCT_GETLIST)
                .addHeaders("Authorization", "bearer " + prefHelper.getAccessToken())
                .addQueryParameter("searchBy", searchBy)
                .addQueryParameter("categoryIds", categoryIds)
                .addBodyParameter(request)
                .setOkHttpClient(okHttpClient)
                .build()
                .getObjectObservable(ProductResponse::class.java)
                .doOnError {
                    t: Throwable -> Log.e("performProductListApiCall", t.message);
                }

Answer 1

之前：

.setOkHttpClient(okHttpClient)

添加以下行：

OkHttpClient okHttpClient= new OkHttpClient();
client.setConnectTimeout(15, TimeUnit.MINUTES); // connect timeout
client.setReadTimeout(15, TimeUnit.MINUTES);    // socket timeout

Web API调用抛出错误java.net.SocketTimeoutException
