我有一個自定義的異常處理程序,如果發生任何異常(只是試用它),應該將用戶帶到自定義錯誤頁面。Angular 2自定義錯誤處理和路由器
我想獲得使用噴油器的路由器的實例。 這樣做的原因,我相信噴油器會給現有的路由器實例和使用它,我將能夠路由用戶。
任何想法爲什麼這不起作用或如何實現?
謝謝:)
@Injectable()
export class AppExceptionHandler extends ExceptionHandler{
constructor(){
super(null, null);
}
call(exception:any, stackTrace?:any, reason?:string):void {
console.log('call...')
var providers = Injector.resolve([ROUTER_PROVIDERS]);
var injector = Injector.fromResolvedProviders(providers);
// this is causing issue, not sure it is the correct way
let router : Router = injector.get(Router);
// not executed
console.log(router)
// not executed
console.log('done...')
router.navigate(["CustomErrorPage"]);
}
}
回答 - 在2.0.0-beta.17測試 由於Druxtan
1. Created a file app.injector.ts inside the app folder (app/app.injector.ts)
let appInjectorRef;
export const appInjector = (injector?) => {
if (!injector) {
return appInjectorRef;
}
appInjectorRef = injector;
return appInjectorRef;
};
2. Added to the bootstrap in the main.ts
bootstrap(AppComponent,[ROUTER_PROVIDERS, HTTP_PROVIDERS,provide(ExceptionHandler,{useClass : AppExceptionHandler})])
.then((appRef) => appInjector(appRef.injector));
3. In the AppExceptionHandler, retrieved the Router instance as shown below
export class AppExceptionHandler {
call(exception:any, stackTrace?:any, reason?:string):void {
let injectorApp = appInjector();
let router = injectorApp.get(Router);
let localStorageService = injectorApp.get(LocalStorageService);
if(exception.message === '-1'){
localStorageService.clear();
router.navigate(["Login"]);
}
}
}
