我们正在构建一个Ionic混合应用程序，并实施了由CI系统运行的自动化E2E测试。所有这些测试都一直正常工作，直到我们在“ app.module”中实现APP_INITIALIZE才能在初始化之前获取浏览器语言。

-app.module.ts

export function configurateLocaleData(dynamicRegisterLocaleService: DynamicRegisterLocaleService): () => Promise<any> {

}

...

providers: [

        }
...

-dynamic-register-locale.service.ts

import {Injectable} from "@angular/core";
import {HttpClient} from "@angular/common/http";
import {AppConfig} from "../app.constants";
import {DateLocaleService} from "./dateLocale.service";
import {registerLocaleData} from "@angular/common";

@Injectable()
export class DynamicRegisterLocaleService {

    constructor(private httpClient: HttpClient) {
    }

    public configurateLocaleData(): Promise<any> {
        let currentLang = DateLocaleService.getLanguage();
        return this.httpClient.get("../assets/locales/" + currentLang + ".js", {responseType: …
