在Angular 13中，可以通过使用useFactory创建一个依赖于通过APP_INITIALIZER加载的另一个服务的提供者。下面是解决该问题的代码示例：

1. 创建一个APP_INITIALIZER：

import { APP_INITIALIZER } from '@angular/core'; import { MyService } from './my.service';

export function myAppInitializer(myService: MyService) { return () => { return myService.load(); }; }

@NgModule({ providers: [ MyService, { provide: APP_INITIALIZER, useFactory: myAppInitializer, deps: [MyService], multi: true } ] }) export class AppModule {}

2. 在另一个服务中使用依赖项：

import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; import { MyService } from './my.service';

@Injectable() export class MyOtherService { constructor(private http: HttpClient, private myService: MyService) {}

public getData() { return this.http.get('/api/data', { params: { id: this.myService.someId } }); } }

3. 创建一个提供者使用useFactory依赖于另一个服务：

import { Injectable } from '@angular/core'; import { MyOtherService } from './my-other.service'; import { MyService } from './my.service';

@Injectable() export class MyProvider { constructor(private myOtherService: MyOtherService, private myService: MyService) {}

public someMethod() { const data = this.myOtherService.getData(); // use the myOtherService and myService dependencies // do something with data } }

export function myProviderFactory(myOtherService: MyOtherService, myService: MyService) { return new MyProvider(myOtherService, myService); }

@NgModule({ providers: [ MyOtherService, MyService, { provide: MyProvider, useFactory: myProviderFactory, deps: [MyOtherService, MyService] } ] }) export class AppModule {}

通过这种方式，我们可以创建一个具有依赖关系的应用程序提供者，并且可以在该提供
