Angular 7 已通过 Gmail 授权

Question

所有人都在尝试使用 angular5-social-login 在 angular 7 中授权 gmail。无论如何它对我有用，但我需要在页面加载时运行该功能。我尝试在ngOnInit 和ngAfterViewInit 中调用它，但出现以下错误：

未捕获（承诺中）：TypeError：无法读取未定义的属性“signIn” TypeError：无法读取未定义的属性“signIn”

import { Component, OnInit, NgZone } from '@angular/core';
import { AuthService, SocialLoginModule } from 'angular5-social-login';
import { GoogleLoginProvider } from 'angular5-social-login'
import { User } from 'src/app/commen/user';
import { CookieService } from 'ngx-cookie-service';
import { HttpClient } from '@angular/common/http';
import { ApiService } from 'src/app/api.service';
import { Router } from '@angular/router'
import { AppComponent } from '../app.component';


@Component({
selector: 'app-login',
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
 export class LoginComponent {
 constructor(
  public SocialAuthService: AuthService,
  private cookie: CookieService,
  private http: HttpClient,
  private _ApiService: ApiService,
  private _user: User,
  private router: Router,
  private app: AppComponent,
 public zone: NgZone

  ) {



if (this.cookie.get('email') != '') {

  this.router.navigate(['\home']);

  }
  }


    googlelogin() {
    let socialPlatformProvider = GoogleLoginProvider.PROVIDER_ID;
  this.SocialAuthService.signIn(socialPlatformProvider).then((userdata) => {
    if (userdata.email.includes('nagwa.com')) {

    this._ApiService.getRole(userdata.email).subscribe((res) => {


      this.cookie.set('email', userdata.email, 12)
      this.cookie.set('name', userdata.name, 12);

      if (res == "admin") {

        this.cookie.set('role', 'true', 12)
      }
      else this.cookie.set('role', 'false', 12)

      this.cookie.set('image', userdata.image, 12)
      this.router.navigate(['\home'])

    }
    )




  }
  else alert("please check with nagwa account")


}).catch(function (err) {

  console.log(err)

});
    }

 ngOnInit() {




    }
    ngAfterViewInit()
     {

   this.googlelogin();
   }

   }

临时解决您的问题

 ngAfterViewInit()
 {

   setTimeout (()=>{this.googlelogin()}, 1000);
 }
