asp.net core 2.0 spa angular + 谷歌地图

Question

我如何在 asp.net core spa angular 应用程序中实现 google map，我已经将脚本包含在我的 index.cshtml 中，但是从 angular 访问它时出错。

import { Component } from '@angular/core';
declare var google: any;
@Component({
    selector: 'home',
    templateUrl: './home.component.html'
})
export class HomeComponent {
    constructor() {
        var mapProp = {
            center: new google.maps.LatLng(51.508742, -0.120850),
            zoom: 5,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
        var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
    }
}

Index.html

@{
    ViewData["Title"] = "Home Page";
}

<app asp-prerender-module="ClientApp/dist/main-server">Loading...</app>
<script src="https://maps.googleapis.com/maps/api/js?key=[YOUR-KEY]" async defer></script>
<script src="~/dist/vendor.js" asp-append-version="true"></script>
@section scripts {
    <script src="~/dist/main-client.js" asp-append-version="true"></script>
}

处理请求时发生未处理的异常。

NodeInvocationException: Uncaught (in promise): ReferenceError: google is not defined ReferenceError: google is not defined at new HomeComponent (F:\yo\ClientApp\dist\main-server.js:16281:25)

.cshtml

<app asp-prerender-module="ClientApp/dist/main-server"
         asp-prerender-data='@ViewData["token"]' >Loading...</app>//Storing 

    <script src="~/dist/vendor.js" asp-append-version="true"></script>
    @section scripts {
        <script src="~/dist/main-client.js" asp-append-version="true"></script>
    }

boot.server.ts

setImmediate(() => {
                    resolve({
                        html: state.renderToString(),

                        globals: {
                            tokenData: params.data
                        }

                    });

应用程序组件.ts

declare var tokenData: any;
@Component({..})
export class AppComponent implements OnInit{
 ngOnInit() {
 let accessToken = tokenData;
 localStorage.setItem('token', accessToken);
     }
}
