Question

我不认为这是可能的，但鉴于此：

接口

import {BrowserService} from "../services/browser/index";

export interface IPrimaryNavigation {
    opts:IPrimaryNavigationOpts;
}

export interface IPrimaryNavigationOpts {
    ...
    browserService:BrowserService;
    ...
}

类：

import {IPrimaryNavigation, IPrimaryNavigationOpts} from "./interface";

export class PrimaryNavigation implements IPrimaryNavigation {
   public opts:IPrimaryNavigationOpts;
   ...
   mounted():void {
        ...
        this.listenForBootstrap(this.opts.bsNav, this.opts.browserService);
    }
    listenForBootstrap(menuName:string,browserService:<???>):void {
                                                       ^^^ here is the problem - 
    // I want to do the equivalent of IPrimaryNavigationOpts.browserService but can't. 
    // I don't think I should have to import the IBrowserService explicitly.

    }
}

你如何解决这个问题。我似乎无法找到任何处理此类问题的在线示例。我承认我对所有这一切都很陌生，所以指点赞赏。

我们可以重新导出旧的东西。所以，在“./ interface”里面我们可以做（查看最后一行）：

import {BrowserService} from "../services/browser/index";

export interface IPrimaryNavigation {
    opts:IPrimaryNavigationOpts;
}

export interface IPrimaryNavigationOpts {
    ...
    browserService:BrowserService;
    ...
}
// re-export used interface
export { BrowserService }

现在，我们甚至可以导入该类型

// we import the re-exported type
import {IPrimaryNavigation, IPrimaryNavigationOpts
        BrowserService } from "./interface";

export class PrimaryNavigation implements IPrimaryNavigation {
   public opts:IPrimaryNavigationOpts;
   ...
   mounted():void {
        ...
        this.listenForBootstrap(this.opts.bsNav, this.opts.browserService);
    }
    listenForBootstrap(menuName:string,browserService:BrowserService):void {
    //listenForBootstrap(menuName:string,browserService:<???>):void {
    //                                                   ^^^ here is the problem - 
    // I want to do the equivalent of IPrimaryNavigationOpts.browserService but can't. 
    // I don't think I should have to import the IBrowserService explicitly.

    }
}

您可以将其输入为：browserService: typeof IPrimaryNavigationOpts.browserService
