Angular 7导航强制返回到根

自从Angular 5升级到Angular 7以来，我在路由方面遇到了问题。

本质上，问题出在从一页导航到另一页。如果在导航栏上，我选择“计划”（与付款计划一样），它将带我到付款计划列表（Stripe中的列表）。然后，一旦选择了计划，就可以使用router.navigate转到Stripe付款表单页面（模板驱动表单）。调试时，我可以看到它导航到付款表单页面，但随后返回到/。

我的路线：

const appRoutes = [
{ path: 'home', component: HomeComponent },
{ path: 'accounts/login', component: LoginFormComponent },
{ path: 'accounts/register', component: RegistrationFormComponent },
{ path: 'plans', component: StripePlansComponent },
//{ path: 'pay', component: StripeFormComponent, canActivate: [IsLoggedinGuardService, HasSelectedPlanGuardService] },
{ path: 'pay', component: StripeFormComponent },
{ path: 'privacy', component: PrivacyStatementComponent },
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: '**', component: PageNotFoundComponent }

];

此刻，我已对我的“付款”路线进行了注释，以确保不要责怪Gaurds。

我的导航菜单组件：

<li class="nav-link" routerLinkActive="active">
    <a [routerLink]="['plans']">
        <span class='fa fa-money-bill-alt' style="margin-right: 10px"></span> Pay </a>
</li>

我的计划组件：

import { Component, Inject, OnInit, OnDestroy, ElementRef, ViewChild } from '@angular/core';
import { Router } from '@angular/router';
import { Observable } from 'rxjs/Observable';

import { PaymentService } from '../../shared/services/payment.service';

@Component({
    templateUrl: 'stripe-plans.component.html',
    styleUrls: ['stripe-plans.component.css'],
})

export class StripePlansComponent implements OnInit {

    public plans: Observable<StripePlan[]>;
    selectedPlan: StripePlan | undefined = undefined;

constructor(private _paymentService: PaymentService, private _router: Router) {

}

    ngOnInit() {
        this.plans = this.GetAllPlans();
    }

    GetAllPlans()  {
        return this._paymentService.getAvailablePlans();
    };

    ClickHandler(plan: StripePlan) {
        this._paymentService.setSelectedPlan(plan);
        this._router.navigate(['pay']);
    }
}

我的计划HTML （我正在使用异步管道来处理订阅/取消订阅）：

<div class="center">
<h1>Payment Plans</h1>

<div class="row">
    <div class="col-sm-2" *ngFor="let plan of plans | async">
        <div class="card" style="width: 18rem;">
            <div class="card-header">
                <div class="price-container">
                    <div class="price">
                        <span class="label">Buy</span>
                        <span class="number">{{ plan.Amount / 100 | currency: plan.Currency:'symbol-narrow':'1.2-2' }}</span>
                        <span class="label">Now</span>
                    </div>
                </div>
            </div>
            <div class="card-body">
                <h3 class="card-title">{{ plan.PlanId }}</h3>
                <p class="card-text">{{ plan.Amount / 100 | currency: plan.Currency:'symbol-narrow':'1.2-2' }} per {{ plan.Interval }} </p>
                <a href="#" class="btn btn-primary" (click)="ClickHandler(plan)">Select</a>
            </div>
        </div> 
    </div>
</div>

正如您在上面的javascript中看到的那样，我正在从点击处理程序中导航。

我的表单组件：

import { Component, NgZone, OnInit } from '@angular/core';
import { Router } from '@angular/router';
import { UserService } from '../../shared/services/user.service';
import { PaymentService } from '../../shared/services/payment.service';
import { NgxSpinnerService } from 'ngx-spinner';
import * as moment from 'moment';

@Component({
    templateUrl: 'stripe-form.component.html',
    styleUrls: ['stripe-form.component.css']
})

export class StripeFormComponent implements OnInit {

    Stripe: any;
    model: any = {};

   message: string | undefined = undefined;
   errorMessage: string | undefined = undefined;

   selectedPlan: StripePlan | undefined;
   submitted: boolean = false;
   valuesMonth: any[];
   valuesYear: any[];

  constructor(private paymentService: PaymentService, private _zone: NgZone, private _router: Router, private _userService: UserService, private spinner: NgxSpinnerService) {
      this.Stripe = ( < any > window).Stripe;
  }

  ngOnInit() {
       this.selectedPlan = this.paymentService.getSelectedPlan();
  }

此外，除了“导航到https://localhost:5001/”之外，路由输出中没有其他异常。

我将不胜感激。这真让我感到困惑。

您是否尝试过从链接中删除href属性：<a href="#" class="btn btn-primary" (click)="ClickHandler(plan)">Select</a>有时可能会影响路由器的行为。
