Angular 在提供程序中添加工厂时发生ng生成错误

我在学校做一个项目。我创建了一个基本的HttpFactory，并将其添加到app.module.ts中的提供程序中，但在运行ng build时，出现以下错误：

无法读取未定义的属性“提供”时出错

谢谢

导入app.module.ts、Http、HttpFactory、XHRBackend和RequestOptions中的代码：

providers: [
    AppSettings,
    ProductService,
    CommandService,
    BetService,
    AccountService,
    MasterService,
    ProductCategoryService,
    MasterService,
    UserWalletService,
    TransactionService,
    Window,
    {
        provide: Http,
        useFactory: HttpFactory,
        deps: [XHRBackend, RequestOptions]
    }
],
bootstrap: [AppComponent]

我相信您拼错了

HttpFactory

。它是

httpFactory

，带有小写字母h。所以它不能读取未定义的属性

Window,
{
    provide: Http,
    useFactory: httpFactory,
    deps: [XHRBackend, RequestOptions]
}

我将其命名为HttpFactory，导入工作正常：从“/factories/HttpFactory.factory”导入{HttpFactory}：/好的。。。如果您正在创建自己的工厂，请确保实现了工厂接口，它将帮助您排除错误。如果附加factory源代码，就很容易看出哪里出了问题……事实上，我发现，这是“窗口”提供程序，我在处理visual studio项目之前，现在正在处理一个使用cli编译的项目，我必须删除它（我还没有替换它）。谢谢
