我想让电子邮件在angular和firebase中对gmail进行身份验证,所以我创建了功能
one_read['user']['place']['country']
。
auth-client.service.ts
getAuth (){ return this.afAuth.authState.pipe (map (auth => auth));}
我将电子邮件身份验证分配给navbar.component.ts(userLoggedIn)中的一个变量。
navbar.component.ts
import { map } from 'rxjs/operators';
import { Injectable } from '@angular/core';
import { AngularFireAuth } from 'angularfire2/auth';
import * as firebase from 'firebase/app'
@Injectable({
providedIn: 'root'
})
export class AuthClientService {
constructor(private afAuth:AngularFireAuth) { }
getAuth(){
return this.afAuth.authState.pipe(map(auth=>auth));
}
}
最后我想在navbar.component.html中显示它,但要显示rine。 navbar.component.html
import { Router } from '@angular/router';
import { FlashMessagesService } from 'angular2-flash-messages';
import { AuthClientService } from './../../services/auth-client.service';
import { Component, OnInit } from '@angular/core';
@Component({
selector: 'navbar',
templateUrl: './navbar.component.html',
styleUrls: ['./navbar.component.css']
})
export class NavbarComponent implements OnInit {
isLoggedIn:boolean=false;
userLoggedIn:string;
constructor(
private authService:AuthClientService,
private flashMessage:FlashMessagesService,
private route:Router
) { }
ngOnInit() {
this.authService.getAuth().subscribe(auth=>{
if(auth){
return this.isLoggedIn=true;
this.userLoggedIn = auth.email;
}else{
this.isLoggedIn=false;
}
})
}
}
答案 0 :(得分:2)
更改此:
ngOnInit() {
this.authService.getAuth().subscribe(auth=>{
if(auth){
return this.isLoggedIn=true;
this.userLoggedIn = auth.email;
}else{
this.isLoggedIn=false;
}
})
}
对此:
ngOnInit() {
this.authService.getAuth().subscribe(auth=>{
if(auth){
this.userLoggedIn = auth.email;
this.isLoggedIn = true;
}else{
this.isLoggedIn = false;
}
})
}
