OAuth简述：OAuth 2.0 的一个简单解释，理解OAuth 2.0
Angular引入OAuth 2.0：Angular-oauth2-oidc文档
业务逻辑：客户端请求登录 -> 跳转授权地址并登录 -> 返回客户端重定向地址 -> 返回客户端地址
1.创建Angular 2项目
2.项目创建完成后安装 angular-oauth2-oidc
npm i angular-oauth2-oidc --save
3.安装完成后打开 AppModule 引入 OAuthModule
import { HttpClientModule } from '@angular/common/http';
import { OAuthModule } from 'angular-oauth2-oidc';
@NgModule({
imports: [
HttpClientModule,
OAuthModule.forRoot()
],
declarations: [
AppComponent,
],
bootstrap: [
AppComponent
]
})
export class AppModule {
}
4.建立 OAuthConfig 简单配置文件（更多配置请链接至Angular-oauth2-oidc文档）
（1）issuer：后端授权地址
（2）redirectUrl：授权后返回客户端的地址
（3）logoutUrl：用户退出地址
（4）clientId：后端设置的客户端ID
（5）scope：需要授权的权限
（6）sessionChecksEnabled：session检查
（7）requireHttps：是否https
（8）silentRefreshRedirectUri：token到期刷新
import { AuthConfig } from 'angular-oauth2-oidc';
export const authConfig: AuthConfig = {
// Url of the Identity Provider
issuer: 'https://steyer-identity-server.azurewebsites.net/identity',
// URL of the SPA to redirect the user to after login
redirectUri: 'http://127.0.0.1:3000/callback',
// The logout url
logoutUrl: 'http://127.0.0.1:3000/index',
// The SPA's id. The SPA is registered with this id at the auth-server
clientId: 'spa-demo',
// set the scope for the permissions the client should request
// The first three are defined by OIDC. The 4th is a usecase-specific one
scope: 'openid profile email voucher',
/**
* If true, the lib will try to check whether the user
* is still logged in on a regular basis as described
* in http://openid.net/specs/openid-connect-session-1_0.html#ChangeNotification
*/
sessionChecksEnabled: false,
/**
* Defines whether https is required.
* The default value is remoteOnly which only allows
* http for localhost, while every other domains need
* to be used with https.
*/
requireHttps: false,
// The redirect uri used when doing silent refresh
silentRefreshRedirectUri: 'http://127.0.0.1:3000/assets/html/silent-refresh.html'
}
5.建立 AppService 请求OAuth，并引入 OAuthConfig 配置文件
import { Injectable } from '@angular/core';
import { OAuthService } from 'angular-oauth2-oidc';
import { JwksValidationHandler } from 'angular-oauth2-oidc';
import { OAuthConfig } from './OAuthConfig';
@Injectable({
providedIn: 'root'
})
export class AppService {
constructor(
private oauthSrv: OAuthService,
) { }
public oauthConfig() {
this.oauthSrv.configure(OAuthConfig.authConfig);
this.oauthSrv.setStorage(localStorage);
this.oauthSrv.tokenValidationHandler = new JwksValidationHandler();
this.oauthSrv.loadDiscoveryDocumentAndTryLogin({
onTokenReceived: url => {
window.parent.location.href = url.state;
}
});
this.oauthSrv.setupAutomaticSilentRefresh();
}
public identityValid() {
if (this.oauthSrv.hasValidAccessToken()) {
return true;
}
this.login();
return false;
}
public login() {
const href = window.location.href;
this.oauthSrv.initLoginFlow(href);
}
public logOut() {
this.oauthSrv.logOut();
}
}
6.在 AppComponent 中调用 AppService 的 oauthConfig 方法
import { Component } from '@angular/core';
import { AppService } from './service/app.service';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent {
constructor(
private appSrv: AppService
) {
this.appSrv.oauthConfig();
}
}
7.创建 login 组件并引入 AppService 及调用登录
async login() {
await this.appSrv.login();
}
8.创建 project 组件并引入 AppService 调用验证登录
ngAfterViewInit(): void {
this.init();
}
async init() {
await this.appSrv.identityValid();
}
9.创建 callback 组件，仅作为后端授权成功后的重定向地址
10.token的自动刷新，在 assets 中创建 silent-refresh.html 单页面（参考）
<html>
<body>
<script>
parent.postMessage(location.hash, location.origin);
console.info('token has refreshed');
</script>
</body>
</html>
