APP_BASE_HREF

预定义的 DI 令牌,用于和 PathLocationStrategy 一起使用的 base href。base href 是在生成和识别 URL 时应保留的 URL 前缀。

A predefined DI token for the base href to be used with the PathLocationStrategy. The base href is the URL prefix that should be preserved when generating and recognizing URLs.

      
      const APP_BASE_HREF: InjectionToken<string>;
    

使用说明

以下示例演示了如何使用此令牌为基本应用注入器配置 base href 值,以便 DI 框架可以在应用中的任何位置提供依赖项。

The following example shows how to use this token to configure the root app injector with a base href value, so that the DI framework can supply the dependency anywhere in the app.

      
      import {Component, NgModule} from '@angular/core';
import {APP_BASE_HREF} from '@angular/common';

@NgModule({
  providers: [{provide: APP_BASE_HREF, useValue: '/my/app'}]
})
class AppModule {}
