APP_BASE_HREF

The APP_BASE_HREF token represents the base href to be used with the PathLocationStrategy.

const APP_BASE_HREF: InjectionToken<string>;

说明

If you're using PathLocationStrategy, you must provide a provider to a string representing the URL prefix that should be preserved when generating and recognizing URLs.

Example

import {Component, NgModule} from '@angular/core'; import {APP_BASE_HREF} from '@angular/common'; @NgModule({ providers: [{provide: APP_BASE_HREF, useValue: '/my/app'}] }) class AppModule {}
