我在使用地图路线服务时遇到此错误的帮助,我正在关注使用ng-2和SebastianM / angular2-实施Google地图路线服务的问题Directions service #495谷歌地图,我不确定我是否遗漏了一些东西,我已经对此进行了真正的研究,并且需要有关错误来源的帮助。

EXCEPTION: Uncaught (in promise): RangeError: Maximum call stack size exceeded
RangeError: Maximum call stack size exceeded

这是方向服务组件/指令,我已经在我的module.ts中声明了

import { Component, OnInit, Input } from '@angular/core';
import { MapsAPILoader, SebmGoogleMap, GoogleMapsAPIWrapper} from 'angular2-google-maps/core';
import { Session } from '../../../session';

declare var google: any;
@Component({
 selector: 'sebm-google-map-directions',
 templateUrl: 'app/modules/move_requests/components/sebm-google-directions.component.html',
 styleUrls: [
    'app/modules/move_requests/components/move_requests.component.css'
]
})

export class DirectionsMapDirective  implements OnInit {
  @Input() origin: any;
  @Input() destination: any;
constructor(private mapsAPI: MapsAPILoader,private mapsAPIWrapper: GoogleMapsAPIWrapper) {}

ngOnInit(): void {
    let latlngOrigin = Session.get('location_coordinates');
    let latlngDest = Session.get('to_location_coords');

    this.mapsAPIWrapper.getNativeMap().then(map =>{

    this.origin = new google.maps.LatLng(latlngOrigin.lat,latlngOrigin.lng);
    this.destination = new google.maps.LatLng(latlngDest.lat,latlngDest.lng);

        var directionsService = new google.maps.DirectionsService;
        var directionsDisplay = new google.maps.DirectionsRenderer;
        directionsDisplay.setMap(map);
        directionsService.route({
            origin: this.origin,
            destination: this.destination,
            waypoints: [],
            optimizeWaypoints: true,
            travelMode: 'DRIVING',

        },function (res: any, status: any){
            if( status === 'OK') {
                console.log("STATUS WAS OK");
                directionsDisplay.setDirections(res)
            } else {
                window.alert('Directions request failed due to ' + status);
            }
        });
    });
}

并在模板中有这个

<sebm-google-map style="height: 300px;">
   <sebm-google-map-directions [origin]="origin" [destination]="destination"></sebm-google-map-directions>
</sebm-google-map>

任何可能导致我解决错误的帮助或建议都将不胜感激,谢谢。

我的错是我没有指示服务作为指令,但是一个组件,我已经将指示服务移动到指令,并在我的模块中声明它然后将其用作html标签在主机组件中,如果有人想看到代码,只需评论这个问题的主题。
