直接上代码
@NgModule({
imports: [
StoogesModule,
IdentityRoutingModule
],
exports: [],
declarations: [LoginComponent],
providers: [
IdentityService,
{
provide: APP_INITIALIZER,
useFactory: IdentityInitializeFactory, //这里不要用匿名函数, webpack 会报错
deps: [IdentityService],
multi: true
},
AdminAuthorizeGuard,
ShopAuthorizeGuard
],
})
export class IdentityModule { }
factory 返回方法, 然后返回 promise.
export function IdentityInitializeFactory (identityService: IdentityService)
{
return async () => {
await identityService.getUserByCookies();
}
}
