角6神秘的堆栈轨迹: globalZoneAwareCallback

Question

最近，使用Angular6，我开始在浏览器控制台中观察到描述性极差的堆栈跟踪：

错误：“对象” resolvePromise http://localhost:8080/polyfills.js:3136:31 resolvePromise http://localhost:8080/polyfills.js:3093:17 scheduleResolveOrReject http://localhost:8080/polyfills.js:3195:17 invokeTask http://localhost:8080/polyfills.js:2743:17 onInvokeTask http://localhost:8080/vendor.js:36899:24 invokeTask http://localhost:8080/polyfills.js:2742:17 runTask http://localhost:8080/polyfills.js:2510:28 drainMicroTaskQueue http://localhost:8080/polyfills.js:2917:25 invokeTask http://localhost:8080/polyfills.js:2822:21 invokeTask http://localhost:8080/polyfills.js:3862:9 globalZoneAwareCallback http://localhost:8080/polyfills.js:3888:17 core.js:1673 defaultErrorLogger core.js:1673 ./node_node/@角/core/fesm5 5/core.js /ErrorHandler.prototype.handleError core.js:1719 下一首 core.js:4319:109 ./node_node/@角/core/fesm5 5/core.js /EventEmitter.prototype.subscribe/schedulerFn< core.js:3555:34 ./node_modules/rxjs/_esm5/internal/Subscriber.js /SafeSubscriber.prototype.__tryOrUnsub Subscriber.js:195 ./node_modules/rxjs/_esm5/internal/Subscriber.js /SafeSubscriber.prototype.next Subscriber.js:133 ./node_modules/rxjs/_esm5/internal/Subscriber.js /Subscriber.prototype._next Subscriber.js:77 ./node_modules/rxjs/_esm5/internal/Subscriber.js /Subscriber.prototype.next Subscriber.js:54 ./node_modules/rxjs/_esm5/internal/Subject.js/Subject.prototype.next Subject.js:47 ./node_modules/@angular/core/fesm5/core.js/EventEmitter.prototype.emit core.js:3539:52 onHandleError/< core.js:3846:48 ./node_modules/zone.js/dist/zone.js/ zone.js:388 ./node_modules/zone.js/dist/zone.js/ zone.js:138 ./node_node/@角/core/fesm5 5/core.js /NgZone.prototype.runOutsideAngular core.js:3783 onHandleError core.js:3846 ./node_modules/zone.js/dist/zone.js / zone.js:392 ./node_modules/zone.js/dist/zone.js/ zone.js:154 _loop_1 zone.js:677 ./node_modules/zone.js/dist/zone.js/ zone.js:686 drainMicroTaskQueue zone.js:602 ./node_modules/zone.js/dist/zone.js/ zone.js:500 invokeTask zone.js:1540 globalZoneAwareCallback zone.js:1566

我的怀疑是在路由模块中出现了一些错误，所以我正在粘贴配置：

const routes = [
  {
    path: 'wordspreview/:id',
    component: WordsPreviewComponent
  },
  {
    path: 'wordspreview',
    component: WordsPreviewComponent
  },
  {
    path: 'search/:query',
    component: SearchResultsComponent
  },
  {
    path: '',
    redirectTo: '/wordspreview',
    pathMatch: 'full'
  }
};

希望有人能帮忙。

Answer 1

我刚为自己找到了窃听器。

由于无法在其他任何地方搜索，我将在这里留下解决方案，以帮助下一个潜在受害者：

constructor(private router : Router,
[...]
this.router.navigate([site, id]);

我做错的是进入错误的site。调试很困难，因为它只出现在一些罕见的错误site值上。
