Question

我们正忙着填写注册表，用户需要上传图像，因此我们决定将图像保存到Google Firebase。

尝试将图像上传到Firebase时出现此错误：

No provider for InjectionToken angularfire2.app.options!

我的app.module.ts文件：

other imports

import { AngularFireStorage } from 'angularfire2/storage';
import { AngularFireModule } from '@angular/fire';
import { AngularFireDatabaseModule } from '@angular/fire/database';

@NgModule({
  imports: [
    BrowserModule,
    BrowserAnimationsModule,     
    FormsModule, 
    
    AngularFireModule.initializeApp({
      apiKey: "----------",
      authDomain: "-------------",
      projectId: "------------",
      storageBucket: "---------",
    }),
    AngularFireDatabaseModule,
    ReactiveFormsModule,
    CommonModule,
    NgxGaugeModule,
    NgxChartsModule,
    HttpClientModule,
    AgmCoreModule.forRoot({
      apiKey: 'AIzaSyAir4tXhx3X-wcdZnhe8TLlo9J2m_AKx6w'
    }), 
    PerfectScrollbarModule, 
    CalendarModule.forRoot({
      provide: DateAdapter,
      useFactory: adapterFactory
    }),
    SharedModule,
    PipesModule,
    routing
  ],
  declarations: [



        *all declarations here*
   
  
  
 
  ],
  entryComponents:[
    VerticalMenuComponent
  ],
  providers: [ 
    AppSettings,
    { provide: PERFECT_SCROLLBAR_CONFIG, useValue: DEFAULT_PERFECT_SCROLLBAR_CONFIG },
    { provide: OverlayContainer, useClass: CustomOverlayContainer },
    AngularFireStorage
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

我要执行上传的.ts中的导入：

import { AngularFireStorage } from 'angularfire2/storage';

我试图上传图像的ts函数：

  public onSubmit(event) {
    const randomId = Math.random().toString(36).substring(2);
    this.ref = this.afStorage.ref(randomId);
    this.task = this.ref.put(this.files[0]);
    this.uploadProgress = this.task.percentageChanges();
    this.downloadURL = this.task.downloadURL();
    alert(this.downloadURL);

  }

  onSelectedFile(event){
    if (event.target.files.length > 0){
      event.target.files[0].name = this.SubmitData.IDNum;
       this.files = event.target.files[0];
      
    }
  }
