Angular 错误：无法匹配任何路由。URL段：'；空'；在离子角应用程序中

我正在开发一个使用Ionic 4和Angular的应用程序，我得到以下错误：

知道我做错了什么吗？？？？任何帮助都将不胜感激。谢谢。

从Ionic中，

IoninViewDidLoad（）

在加载页面后运行，因此您在加载视图后调用函数。

---

而是在

ionViewWillEnter（）

方法中调用您的方法。

我通过在ngOnInit上调用我的函数解决了这个问题，如下所示：

ionViewDidLoad() {
    this.callCloudFunction();
}

async callCloudFunction() {

    var memberUrl = 'https://www.example.com/WebRes/Club/XYZ/LoginWithToken/' + memberToken;
      console.log("Login URL: " + memberUrl);
      this.url =  this.sanitizer.bypassSecurityTrustResourceUrl(memberUrl);
}

<ion-content>
  <div style="overflow:auto;-webkit-overflow-scrolling:touch">
      <iframe [src]="url" style="width: 100%; height: 100vh;" frameborder="0"></iframe>
    </div>
</ion-content>

import { NgModule } from "@angular/core";
import { PreloadAllModules, RouterModule, Routes } from "@angular/router";

import { AuthGuard } from "./guard/auth.guard";
import { NoAuthGuard } from "./guard/no-auth.guard";

const routes: Routes = [
  { path: "", redirectTo: "login", pathMatch: "full" },

  { path: "my-page", loadChildren: "./my-page/my-page.module#MyPagePageModule",canActivate: [AuthGuard] }

@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules })

export class AppRoutingModule {}

ngOnInit() {
      this.callCloudFunction().then( data => {
        this.urlSafe= this.sanitizer.bypassSecurityTrustResourceUrl(this.url);
        this.canRender = true;
     });
    }

<div style="overflow:auto;-webkit-overflow-scrolling:touch" *ngIf="canRender">
      <iframe [src]="urlSafe" style="width: 100%; height: 100vh;" frameborder="0"></iframe>
    </div>

然后在我的html中，我将ngif设置如下：

您可以显示路线吗module@ORBIT我已经在上面添加了路由模块。这不是一个好的做法，因为如果在将页面放入堆栈后返回页面，ngOnInit（）将不会被触发。正如我在回答中提到的那样，使用ionViewWillEnter（）。你是一个救生员！！3天后，我终于找到了解决问题的方法
