[浏览器][cordova.js][xhrStatusChangeHandler] 无法 XHR config.xml：未找到

Question

我正在尝试使用 ionic 4、angular 6、Nodejs 10 开发应用程序，并且需要集成谷歌地图。当我运行我的应用程序时，我总是在开发工具浏览器控制台中看到这个错误 - [Browser][cordova.js][xhrStatusChangeHandler] Could not XHR config.xml: Not Found。最后复制了完整的控制台。

以下是我的代码 -

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';

import { GoogleMaps } from '@ionic-native/google-maps';

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [
    BrowserModule,
    IonicModule.forRoot(),
    AppRoutingModule
  ],
  providers: [
    StatusBar,
    GoogleMaps,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

以下是我的app.component.ts 文件 -

import { Component, ViewChild } from '@angular/core';

import { Platform, Nav } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';
import { HomePage } from './home/home.page';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html'
})
export class AppComponent {

  @ViewChild(Nav) nav: Nav;

  rootPage: any;

  public appPages = [
    {
      title: 'Home',
      url: '/home',
      icon: 'home'
    },
    {
      title: 'List',
      url: '/list',
      icon: 'list'
    }
  ];

  constructor(
    private platform: Platform,
    private splashScreen: SplashScreen,
    private statusBar: StatusBar
  ) {
    this.initializeApp();
  }

  initializeApp() {
    this.platform.ready().then(() => {
      this.rootPage = HomePage;
      this.statusBar.styleDefault();
      this.splashScreen.hide();
    });
  }
}

home.page.ts

import { Component, OnInit } from '@angular/core';
import { GoogleMaps, GoogleMap } from '@ionic-native/google-maps/ngx';
import { Platform } from '@ionic/angular';
import { Environment } from '@ionic-native/google-maps';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage implements OnInit {
  map: GoogleMap;

  constructor( private platform: Platform) {}

  async ngOnInit() {
    await this.platform.ready();
    await this.loadMap();
  }

  loadMap() {
    Environment.setEnv({
      'API_KEY_FOR_BROWSER_RELEASE': 'Agktkllffff1xGYLjDF0v1i2RSDrqDLjEmDdLI',
      'API_KEY_FOR_BROWSER_DEBUG': ''
    });

    this.map = GoogleMaps.create('map_canvas');
  }
}

home.page.html

<ion-header>
  <ion-toolbar>
    <ion-buttons slot="start">
      <ion-menu-button></ion-menu-button>
    </ion-buttons>
    <ion-title>
      Home
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content padding>
  <h3>GoogleMaps</h3>
  <div id = "map_canvas">
    <button ion-button (click)="onButtonClick($event)">Demo</button>
  </div>
</ion-content>

我检查了我的 Google Map API 密钥，它没有问题，并仔细检查了我使用的是正确的密钥。我的帐户也很好，应该没有问题。我想知道是什么导致了这个问题。我用来运行我的应用程序的命令是 -

ionic cordova run browser -l

打开的网址是http://172.29.54.8:8100/home

Answer 1

try {
    xhr.open("get", "/config.xml", true);
    xhr.send();
} catch(e) {
    fail('[Browser][cordova.js][readConfig] Could not XHR config.xml: ' + JSON.stringify(e));
}

尝试在平台的 cordova.js 文件中找到这些行。 我猜您的应用程序位于子文件夹中。因此错误。改成

try {
    xhr.open("get", "/<foldername>/config.xml", true);
    xhr.send();
} catch(e) {
    fail('[Browser][cordova.js][readConfig] Could not XHR config.xml: ' + JSON.stringify(e));
}

Answer 2

我在运行命令时遇到问题

ionic cordova build browser

并将错误的构建内容吞入服务器，

wwwunber platforms/browser 是正确的

项目文件夹下的www是错误的一个

Answer 3

就我而言，我正在启动我的应用程序，如下所示 http://1.2.3.4/MyApp.BETA/

我认为更好的方法是假设 当前目录 而不是 root。因此修复应该是：

xhr.open("get", "./config.xml", true);

这个cordova.js的来源在哪里？

应该通知谁来解决这个问题？科尔多瓦？

谢谢。
