Keyloak-angular (https://github.com/mauriciovigolo/keycloak-angular) - 注册 - CORS 错误

如何解决Keyloak-angular (https://github.com/mauriciovigolo/keycloak-angular) - 注册 - CORS 错误

我正在使用 keycloak-angular 库 (https://github.com/mauriciovigolo/keycloak-angular) 将 Keycloak 集成到我的 SPA 中。 SpringBoot 暂时不涉及

登录按预期工作。注册在我的 Angular 应用程序中引发以下错误。

我的 Angular 代码：

app.init.ts：

import { KeycloakService } from 'keycloak-angular';

export function initializeKeycloak(keycloak: KeycloakService) {
    return () =>
      keycloak.init({
        config: {
          url: 'http://localhost:8080/auth',realm: 'mealplanner',clientId: 'meal-planner-app-client'
        },loadUserProfileAtStartUp : true
      });
  }

app.module.ts：

providers : [ 
    ...
    {provide: APP_INITIALIZER,useFactory: initializeKeycloak,multi: true,deps: [KeycloakService]}]

与错误无关的代码（为了完整性而包含在内）：

/app-info/home 对所有人可见。 /app-info/user 受登录保护。

app-routing.module.ts:

const appRoutes:  routes = [
    {path:'meal-planner',component: UserComponent,canActivate: [AuthGuardService]}
];  

auth-guard.service.ts：

export class AuthGuardService extends KeycloakAuthGuard {
  constructor(
    protected readonly router: Router,protected readonly keycloak: KeycloakService
  ) {
    super(router,keycloak);
  }

  public async isAccessAllowed(
    route: ActivatedRouteSnapshot,state: RouterStateSnapshot
  ) {
    
    // Force the user to log in if currently unauthenticated.
    if (!this.authenticated) {
    
      await this.keycloak.login({
        redirectUri: window.location.origin + state.url
      });
    }

    else return true;
  }
}

在 Keycloak 中：Clients -> Meal-planner-client -> WebOrigins -> *（也尝试使用 + 和 localhost:4200） - 不起作用

客户端 -> 设置 -> 访问类型 -> 公共

版本： "keycloak-angular": "^8.1.0","keycloak-js": "^12.0.4",角 10 钥匙斗篷：12.0.4

提前致谢。
