如何首先执行函数,然后再执行canActivate()

我有这个AuthGuard。在此代码中,我想创建一个条件。如果我的resetpasss不为null,我想在这里浏览ResetPassIdComponent,否则我想在LoginFirstComponent中浏览。

为此,我创建了AuthGuard。

export class AuthGuard implements CanActivate {
    myappurl: any;
    resetpasss: any;
    constructor(private router: Router, private auth: LoginService) {
    }
    geturl() {
        handleOpenURL((appURL: AppURL) => {
            console.log('Got the following appURL1', appURL);
            this.myappurl = appURL
            let url_1 = this.myappurl.toString();
            let url_id = url_1.split("/").reverse()[0];
            this.resetpasss = url_id
            let LS = require("nativescript-localstorage");
            LS.setItem(this.resetpasss)
            // this.router.navigateByUrl('/resetPasswordRequest/' + this.resetpasss);
            console.log('this.resetpass1', this.resetpasss)
        });
        return true;
    }
    canActivate(): boolean {
        this.geturl();
        if (this.auth.isAuthenticated()) {
            return true;
        }
        console.log('this.resetpasss2', this.resetpasss)
        this.router.navigate(['/outsidelogin/login']);
        return false;
    }
 }

我单击了电子邮件中的链接,该链接在geturl(){..}中显示了我。通过此功能geturl(){..},我得到一个ID并保存在localstorage中。现在,在canActivate()中,我想创建一个条件,以在所需的组件中进行导航。

您能问我如何创建条件的想法吗?

我的routing.ts

const routes: Routes = [
  {
    path: 'home',
    component: HomeComponent,
    canActivate: [AuthGuard],
    children: [
      {
        path: 'fp', component: FirstPageComponent
      }
    ]
  },
  {
    path: 'outsidelogin',
    component: outsideloginComponent,
    children: [
      { path: 'login', component: LoginFirstComponent },
      { path: 'register', component: RegisterComponent },
    ]
  },
    { path: '', redirectTo: '/home/fp', pathMatch: 'full' },
    { path: 'resetPasswordRequest/:id', component: ResetPassIdComponent }
];

您可以在 CanActivate()本身中添加条件。您可以尝试以下方法吗?

canActivate(): boolean {
    this.geturl();
    if (this.auth.isAuthenticated()) {
        return true;
    } else if(this.resetpasss){
       this.router.navigate([this.myappurl]);
    }else{
        this.router.navigate(['/outsidelogin/login']);
    }       
}
