javascript - 类型 'Subscription' 缺少类型 'Observable<any>' : _isScalar, 源、运算符(operator)、提升和其他 6 个属性的以下属性

Question

我需要从 Angular 8 的两个 api 返回数据。

我创建了这个解析器:

export class AccessLevelResolve implements Resolve<any>{

constructor(private accessLevel: AccessLevelService) { }

resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> {
    let id = +route.paramMap.get('id');

    const getControllerList = this.accessLevel.getAll().pipe(
        map(
            res => {
                if (res) {
                    return res.date;
                }
            }
        )
    )

    const getRoleAccessRole = this.accessLevel.getAllWithId(id).pipe(
        map(
            res => {
                if (res) {
                    return res.date;
                }
            }
        )
    )
   return forkJoin(getControllerList, getRoleAccessRole).subscribe(res => {
        return {
            controllerList: res[0],
            accessRoleList: res[1]
        }
    }
    )

}

但它向我显示了这个错误:

Type 'Subscription' is missing the following properties from type 'Observable': _isScalar, source, operator, lift, and 6 more.

有什么问题吗？？？我该如何解决这个问题？

您不在解析器中订阅，您返回可观察和 Angular 订阅:

return forkJoin(getControllerList, getRoleAccessRole).pipe(map(res => {
    return {
        controllerList: res[0],
        accessRoleList: res[1]
    }
}))
