当我拒绝承诺时，此错误将显示在控制台上。 IN CONSOLE： EXCEPTION：未捕获（在承诺中）：null error_handler.js：56 原装STACKTRACE：错误：未捕获（承诺）：null

@Injectable()
export class PaymentScheduleResolve implements Resolve<any> {
    constructor(private rtoService: RtoService,
                private rtoActivationService: RtoActivationService,
                private router:Router,
                private toastr: Toastr) {
    }
    resolve() {
        var self = this;
        return new Promise((resolve, reject) => {
            let rtoInfo = self.rtoActivationService.getRtoInfo();
            if (!rtoInfo) {
                reject("null");// This will produce error on console

            }
            else{
                self.rtoActivationService.getPaymentSchedules(rtoInfo.Id, rtoInfo.Data.RtoRentLength)
                    .then((res: any) => {
                        if (res.Response && res.Response.Code === 200) {
                            resolve(res.Response.Data);

                        }
                        else {
                            reject(null);// This will produce error on console
                        }
                    })
                    .catch((err: any) => {
                        console.log(err);
                        reject(null);// This will produce error on console
                    })
            }
        });

    }

Answer 1

只需使用

resolve(null);

而不是

reject(null);

Answer 2

使用以下方法拒绝解析器。这会将您重定向到默认路由。

<android.support.v7.widget.RecyclerView
            android:id="@+id/freshRecyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:clipToPadding="false"
            android:scrollbars="vertical" />

或者您可以重定向到错误页面

reject({message: err , ngNavigationCancelingError: true});

拒绝承诺解决即服务
