所以我的代码看起来像这样:
export const routes: RouterConfig = [
{ 'path': '', redirectTo: '/jobs', terminal: true, canActivate: [tokenNotExpired()] },
{ path: 'account', component: AccountComponent, canActivate: [!tokenNotExpired()] },
{ path: 'login', component: LoginComponent },
...WihRoutes
];
每当我尝试导航到" account"时,路由都会失败,但由于某种原因,它也会出现以下控制台错误:
browser_adapter.ts:82 EXCEPTION:错误:未捕获(在承诺中):否 提供者为false!BrowserDomAdapter.logError @ browser_adapter.ts:82BrowserDomAdapter.logGroup @ browser_adapter.ts:93ExceptionHandler.call @ exception_handler.ts:58(匿名函数)@ application_ref.ts:374schedulerFn @ async.ts:148SafeSubscriber .__ tryOrUnsub @ Subscriber.ts:240SafeSubscriber.next @ Subscriber.ts:192Subscriber._next @ Subscriber.ts:133Subscriber.next @ Subscriber.ts:93Subject._finalNext @ Subject.ts:154Subject._next @ Subject.ts:144Subject.next @ Subject.ts:90EventEmitter.emit @ async.ts:133onError @ ng_zone.ts:142onHandleError @ ng_zone_impl.ts:95ZoneDelegate.handleError @ zone.js:327Zone.runGuarded @ zone.js:233_loop_1 @ zone.js:487drainMicroTaskQueue @ zone.js:494ZoneTask.invoke @ zone.js:426 browser_adapter.ts:82 STACKTRACE:BrowserDomAdapter.logError @ browser_adapter.ts:82ExceptionHandler.call @ exception_handler.ts:61(匿名函数)@ application_ref.ts:374schedulerFn @ async.ts:148SafeSubscriber .__ tryOrUnsub @ Subscriber.ts:240SafeSubscriber.next @ Subscriber.ts:192Subscriber._next @ Subscriber.ts:133Subscriber.next @ Subscriber.ts:93Subject._finalNext @ Subject.ts:154Subject._next @ Subject.ts:144Subject.next @ Subject.ts:90EventEmitter.emit @ async.ts:133onError @ ng_zone.ts:142onHandleError @ ng_zone_impl.ts:95ZoneDelegate.handleError @ zone.js:327Zone.runGuarded @ zone.js:233_loop_1 @ zone.js:487drainMicroTaskQueue @ zone.js:494ZoneTask.invoke @ zone.js:426 browser_adapter.ts:82错误:未捕获(在承诺中):否 提供者是假的! at resolvePromise(zone.js:538) 在zone.js:515 在ZoneDelegate.invoke(zone.js:323) at Object.onInvoke(ng_zone_impl.ts:72) 在ZoneDelegate.invoke(zone.js:322) 在Zone.run(zone.js:216) 在zone.js:571 在ZoneDelegate.invokeTask(zone.js:356) at Object.onInvokeTask(ng_zone_impl.ts:61) 在ZoneDelegate.invokeTask(zone.js:355)
我不清楚为什么会这样 - 其他人?
答案 0 :(得分:0)
传递给canActivate: [!tokenNotExpired()]
的值必须是提供者。 !tokenNotExpired()
不是有效的提供商。
canActivate: ['tokenExpired']
canActivate: ['!tokenExpired']
并在bootstrap或APP_ROUTER_PROVIDERS
bootstrap(AppComponent, [
{provide: 'tokenExpired', useValue: (a: any, b: any) => tokenExpired()}
{provide: '!tokenExpired', useValue: (a: any, b: any) => !tokenExpired()}
]);
