角5:注射前运行结构体

Question

我有一个带有全局变量的文件：

@Injectable()
export class Globals {
  public baseURL:string;
  public loginURL:string;
  public proxyURL:string;
  public servicesURL:string;

  constructor(platformLocation: PlatformLocation) {
    this.baseURL = (platformLocation as any).location.href;
    this.loginURL = this.baseURL + 'rest/login';
    this.proxyURL = this.baseURL + 'rest/proxy';
    this.servicesURL = this.baseURL + 'rest/serviceRegistry';
  }
}

目前，我的API调用失败了，因为还没有设置变量。是否有一种方法只在构造函数运行时注入此服务，还是必须使用可观察的？

Answer 1

它本身并没有解决。我现在就这样用它：

@Injectable()
export class Globals {
  /** API URLS */
  public baseURL:string = '';
  public loginURL:string = 'rest/login';
  public proxyURL:string = 'rest/proxy';
  public servicesURL:string = 'rest/serviceRegistry';
}
