这是我的 app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HttpModule } from '@angular/http';
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { CookieService } from 'ngx-cookie-service';
import { HttpClientModule } from '@angular/common/http';
import { NgxSpinnerModule } from 'ngx-spinner';
import { NgFlashMessagesModule } from 'ng-flash-messages';
import { NgxfUploaderModule } from 'ngxf-uploader';
import { NgxUploaderModule } from 'ngx-uploader';
import { NumberDirective } from './number.directive';
import { FileSelectDirective } from 'ng2-file-upload';
import { BsDatepickerModule } from 'ngx-bootstrap/datepicker';
@NgModule({
  declarations: [
    AppComponent,
    FirstPageComponent,
    SavePasswordComponent,
    LoginPageComponent,
    VerifyDetailsComponent,
    HomePageComponent,
    ViewOfferLetterComponent,
    ContactOptionComponent,
    SocialLinksComponent,
    ContactUsComponent,
    CompanyDetailsComponent,
    CompanyVisionComponent,
    SaveInformationComponent,
    AboutUsComponent,
    ComponyHistoryComponent,
    TestimonialComponent,
    AllocateOfficeComponent,
    NumberDirective,
    FacilitiesComponent,
    FirstDayRuleComponent,
    CompanyMediaComponent,
    HeaderPagesComponent,
    TestImageGallaryComponent,
  ],
  imports: [
    BrowserModule,
    MatProgressBarModule,
    HttpModule,
    FormsModule,
    HttpClientModule,
    NgxSpinnerModule,
    NgxfUploaderModule,
    NgxUploaderModule,
    NgFlashMessagesModule.forRoot(),
    NgbModule.forRoot(),
    BsDatepickerModule.forRoot(),
    RouterModule.forRoot(
    appRoutes,  // { enableTracing: true } // <-- debugging purposes only
    ),
    ModalGalleryModule.forRoot() // <----------------- angular-modal-gallery module import
  ],
  providers: [
    GlobalService,
    AuthguardGuard,
    SuperAdmiApiService,
    EmployeeApiService,
    CookieService
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

这是我可以生成错误的组件

  };
  constructor(private EmployeeApi: EmployeeApiService, private _global: GlobalService, private cookieService: CookieService) {
    this.candidateid = this.cookieService.get('candidateid');
    this.compid = this.cookieService.get('companyid');
    this.imageUrl = this._global.CompanyImagePath;
}
  resolve(route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot,
   ): Observable<any[]> {
   this.data = this.EmployeeApi.getimagegallarydata(this.compid, this.candidateid ).pipe(map(
      resultArray => {
    this.Response = resultArray;
    if (this.Response.status === 200) {
        this.gallaryData = this.Response.gallarydata;
        for ( this.i = 0; this.i < this.gallaryData.length; this.i++) {
          // alert(this.i);
          this.Image[this.i] =
            new Image(
              this.i,
              { // modal
                img: this.imageUrl + this.gallaryData[this.i].filename,
                extUrl: 'http://www.google.com'
              }
            );
        }
        console.log(this.Image);
      } else {
      this.responseMessage = 'Gallary not available';
      alert(this.responseMessage);
    }
    }
    )
  );
  return void(0);
}
ngOnInit() {
  this.pageload();
}
 // set page ui according to screen size
 pageload() {
  $.fn.center = function () {
    this.css('position', 'absolute');
    this.css('top', Math.max(0, (($(window).height() - $(this).outerHeight()) / 2) +
     $(window).scrollTop()) + 'px');
     this.css('left', Math.max(0, (($(window).width() - $(this).outerWidth()) / 2) + $(window).scrollLeft()) + 'px');
       return this;
   };
   $('#abc0').center();
}
}

staric injectore error in angular 4
我在角度6中有静态注入问题,实际上我在app.module.ts中导入httpclientmodule而ad在导入数组中

    看起来您正在尝试将组件用作解析器 .

    解析器的目的是服务,因为它们应该在模块的 providers 数组中注册 - 我怀疑这就是你收到注入器错误的原因 .

    理想情况下,您应该将 resolve 拆分为单独的类,使用 @Injectable 进行修饰,并在模块的 providers 数组中引用它 .

    你的解析器看起来像这样:

    @Injectable()
    export class TestImageGallaryComponentResolver implements Resolve<any> {
      resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<any> {
        // Get your data here and return it. This class can receive dependencies in the constructor.
      }
    }
    

    你的路由器配置看起来像这样:

    {
      path: 'gallery'
      component: TestImageGallaryComponent,
      resolve: {
        data: TestImageGallaryComponentResolver
      }
    }
    

    您的组件可以按如下方式访问数据:

    @Component({
      selector: 'app-test-image-gallary',
      templateUrl: './test-image-gallary.component.html',
      styleUrls: ['./test-image-gallary.component.css']
    })
    export class TestImageGallaryComponent implements OnInit {
      constructor(activatedRoute: ActivatedRoute) {
        activatedRoute.data.subscribe(resolvedData => {
          // Do stuff with resolvedData.data
        });
      }
    }
    

    使用组件作为自己的解析器并不是我曾经想过的事情,但我工作了 . 如果将组件添加到 providers 数组,它可能会运行,但数据不会达到您期望的结果 .

    注入器将提供"component"用于解析为单例,并在视图请求时提供完全不同的组件实例 . 组件在请求时进行新实例化,而 providers 数组中的所有内容都是单例 .

    angular guide提供了一个如何使用解析器的合理深度示例 .
