我试图在azure app服务平台(windows机器)上部署一个角度6应用程序.该应用程序本身只是一个新的角度应用程序(从新的appname生成的基本代码).我在本教程后面添加了一些次要代码,以便使用配置文件并在vsts发布管道中利用变量替换 - 管理带有vsts的角度应用程序的设置.

  static config: AppConfiguration;

  constructor(private http: HttpClient) {}

  load(): Promise<any> {
    const appSettingsJson = environment.production ? 'assets/appsettings.json' : 'assets/appsettings.local.json';
    return new Promise<any>(((resolve, reject) => {
      this.http.get<AppConfiguration>(appSettingsJson)
        .toPromise()
        .then(result => {
          AppSettings.config = result;
          resolve();
        }).catch(reason => {
          reject(`unable to …
