ng g s services/auth
1,领域对象中增加Auth对象。
基于token的认证。
import { User } from './user.model'; import { Err } from './error.model'; export interface Auth { user?: User; userId?: string; err?: string; token?: string; }
2,注册
返回Auth对象。
如果用户已经存在就抛出错误。
//注册 register(user: User): Observable<Auth> { const uri = `${this.config.uri}/${this.domain}`; return this.httpClient .get(uri, { params: { 'email': user.email } }) .pipe( switchMap(res => { if ((<User[]>res).length > 0) { return throwError('username existed'); } return this.httpClient .post(uri, JSON.stringify(user), { headers: this.headers }) .pipe(map(r => ({ token: this.token, user: <User>r }))); }) ) }
3,登录
返回Auth对象。
//登录 login(username: string, password: string): Observable<Auth> { const uri = `${this.config.uri}/${this.domain}`; return this.httpClient.get(uri, { params: { 'email': username, 'password': password } } ) .pipe( map(res => { const users = <User[]>res; if (users.length === 0) { throw new Error('Username or password incorrect'); } return { token: this.token, user: users[0] } })) }
