您好,我现在使用 Angular + Spring Boot 构建网站,在我的网站中,我使用 Okta Single-Page App 进行身份验证。对于前端,我使用的是 okta-angular,并按照此处的说明进行操作:https://github.com/okta/okta-oidc-js/tree/master/packages/okta-angular .我正在使用隐式流。为了简单起见,我使用了 okta 托管的登录小部件。

我的前端代码是这样的:

应用程序模块.ts

import {
OKTA_CONFIG,
OktaAuthModule
} from '@okta/okta-angular';

const oktaConfig = {
issuer: 'https://{yourOktaDomain}.com/oauth2/default',
clientId: '{clientId}',
redirectUri: 'http://localhost:{port}/implicit/callback',
pkce: true
}

@NgModule({
imports: [
...
OktaAuthModule
],
providers: [
{ provide: OKTA_CONFIG, useValue: oktaConfig }
],
})
export class MyAppModule { }

然后我在 app-routing.module.ts 中使用 OktaAuthGuard

import {
OktaAuthGuard,
...
} from '@okta/okta-angular';

const appRoutes: Routes = [
{
path: 'protected',
component: MyProtectedComponent,
canActivate: [ OktaAuthGuard ],
},
...
]

我还在 app-routing.module.ts 中使用 OktaCallBackComponent。

当然我在标题处有登录/注销按钮:

import { Component, OnInit } from '@angular/core';
import {OktaAuthService} from '@okta/okta-angular';

@Component({
selector: 'app-header',
templateUrl: './app-header.component.html',
styleUrls: ['./app-header.component.scss']
})
export class AppHeaderComponent implements OnInit {
isAuthenticated: boolean;
constructor(public oktaAuth: OktaAuthService) {
// Subscribe to authentication state changes
this.oktaAuth.$authenticationState.subscribe(
(isAuthenticated: boolean) => this.isAuthenticated = isAuthenticated
);
}
async ngOnInit() {
this.isAuthenticated = await this.oktaAuth.isAuthenticated();
}

login() {
this.oktaAuth.loginRedirect('/');
}

logout() {
this.oktaAuth.logout('/');
}

}
<nav class="navbar navbar-expand-lg navbar-light">

<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-link" *ngIf="!isAuthenticated" (click)="login()"> Login </a>
<a class="nav-link" *ngIf="isAuthenticated" (click)="logout()"> Logout </a>
</li>
</ul>
</div>
</nav>

在前端用户登录后,我将授权头传递给后端,并且在后端,我使用 spring security 来保护后端 api。像这样:

import com.okta.spring.boot.oauth.Okta;
import lombok.RequiredArgsConstructor;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.http.SessionCreationPolicy;

@RequiredArgsConstructor
@EnableWebSecurity
public class OktaOAuth2WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
// Disable CSRF (cross site request forgery)
http.csrf().disable();

// No session will be created or used by spring security
http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

http.authorizeRequests()
.antMatchers("/api/**").authenticated()
.and()
.oauth2ResourceServer().opaqueToken();

Okta.configureResourceServer401ResponseBody(http);
}
}

如果我在终端中分别运行 angular 和 spring boot,一切正常。我可以登录,我可以在后台获取用户信息。

但是问题是我们在使用gradle build和部署的时候,会把angular编译好的代码放到spring boot项目下的static文件夹中。这时候如果我运行项目:

java -jar XX.jar

然后我在 localhost:8080 打开。

我登录了,那么这个时候认证回调会抛出404 not found错误。

据我了解,原因是当我运行 jar 文件时,我没有为“回调”url 定义 Controller 。但是,如果我分别运行 angular 和 spring boot,angular 由 nodejs 托管,并且我使用了 okta callbackcomponent,所以一切正常。

那么我应该怎么做才能解决这个问题呢?我的意思是,我应该怎么做才能让它作为 jar 文件工作?我应该定义一个回调 Controller 吗?但是我应该在回调 Controller 中做什么?会不会和前端代码冲突??

最佳答案

你很幸运!我刚刚发布了一个blog post今天展示了如何使用单独运行的 Angular + Spring Boot 应用程序(使用 Okta 的 SDK)并将它们打包在一个 JAR 中。您仍然可以使用 ng serve./gradlew bootRun 独立开发每个应用程序,但您也可以使用 ./gradlew bootRun -Pprod 在单个实例中运行它们。在生产模式下运行的缺点是您不会在 Angular 中进行热重载。这里是the steps I used在上述教程中。

创建一个新的 AuthService 服务,它将与您的 Spring Boot API 通信以获取身份验证逻辑。

import { Injectable } from '@angular/core';
import { Location } from '@angular/common';
import { BehaviorSubject, Observable } from 'rxjs';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { environment } from '../../environments/environment';
import { User } from './user';
import { map } from 'rxjs/operators';

const headers = new HttpHeaders().set('Accept', 'application/json');

@Injectable({
providedIn: 'root'
})
export class AuthService {
$authenticationState = new BehaviorSubject<boolean>(false);

constructor(private http: HttpClient, private location: Location) {
}

getUser(): Observable<User> {
return this.http.get<User>(`${environment.apiUrl}/user`, {headers}).pipe(
map((response: User) => {
if (response !== null) {
this.$authenticationState.next(true);
return response;
}
})
);
}

isAuthenticated(): Promise<boolean> {
return this.getUser().toPromise().then((user: User) => {
return user !== undefined;
}).catch(() => {
return false;
})
}

login(): void {
location.href =
`${location.origin}${this.location.prepareExternalUrl('oauth2/authorization/okta')}`;
}

logout(): void {
const redirectUri = `${location.origin}${this.location.prepareExternalUrl('/')}`;

this.http.post(`${environment.apiUrl}/api/logout`, {}).subscribe((response: any) => {
location.href = response.logoutUrl + '?id_token_hint=' + response.idToken
+ '&post_logout_redirect_uri=' + redirectUri;
});
}
}

在同一目录中创建一个 user.ts 文件,以保存您的 User 模型。

export class User {
sub: number;
fullName: string;
}

更新 app.component.ts 以使用新的 AuthService 以支持 OktaAuthService

import { Component, OnInit } from '@angular/core';
import { AuthService } from './shared/auth.service';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {
title = 'Notes';
isAuthenticated: boolean;
isCollapsed = true;

constructor(public auth: AuthService) {
}

async ngOnInit() {
this.isAuthenticated = await this.auth.isAuthenticated();
this.auth.$authenticationState.subscribe(
(isAuthenticated: boolean) => this.isAuthenticated = isAuthenticated
);
}
}

更改 app.component.html 中的按钮以引用 auth 服务而不是 oktaAuth

<button *ngIf="!isAuthenticated" (click)="auth.login()"
class="btn btn-outline-primary" id="login">Login</button>
<button *ngIf="isAuthenticated" (click)="auth.logout()"
class="btn btn-outline-secondary" id="logout">Logout</button>

更新 home.component.ts 以使用 AuthService

import { Component, OnInit } from '@angular/core';
import { AuthService } from '../shared/auth.service';

@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.scss']
})
export class HomeComponent implements OnInit {
isAuthenticated: boolean;

constructor(public auth: AuthService) {
}

async ngOnInit() {
this.isAuthenticated = await this.auth.isAuthenticated();
}
}

如果您使用 OktaDev Schematics 将 Okta 集成到您的 Angular 应用程序中,请删除 src/app/auth-routing.module.tssrc/app/shared/okta .

修改 app.module.ts 移除 AuthRoutingModule 导入,添加 HomeComponent 作为声明,并导入 HttpClientModule.

HomeComponent 的路由添加到 app-routing.module.ts

import { HomeComponent } from './home/home.component';

const routes: Routes = [
{ path: '', redirectTo: '/home', pathMatch: 'full' },
{
path: 'home',
component: HomeComponent
}
];

创建一个 proxy.conf.js 文件,将某些请求代理到 http://localhost:8080 上的 Spring Boot API。

const PROXY_CONFIG = [
{
context: ['/user', '/api', '/oauth2', '/login'],
target: 'http://localhost:8080',
secure: false,
logLevel: "debug"
}
]

module.exports = PROXY_CONFIG;

将此文件添加为 angular.json 中的 proxyConfig 选项。

"serve": {
"builder": "@angular-devkit/build-angular:dev-server",
"options": {
"browserTarget": "notes:build",
"proxyConfig": "src/proxy.conf.js"
},
...
},

从您的 Angular 项目中删除 Okta 的 Angular SDK 和 OktaDev Schematics。

npm uninstall @okta/okta-angular @oktadev/schematics

此时,您的 Angular 应用程序将不包含任何特定于 Okta 的身份验证代码。相反,它依赖于您的 Spring Boot 应用程序来提供这一点。

要配置您的 Spring Boot 应用程序以包含 Angular,您需要配置 Gradle(或 Maven)以在传入 -Pprod 时构建您的 Spring Boot 应用程序,您需要将路由调整为了解 SPA,并修改 Spring Security 以允许访问 HTML、CSS 和 JavaScript。

在我的示例中,我使用了 Gradle 和 Kotlin。

首先,创建一个 RouteController.kt 将所有请求路由到 index.html

package com.okta.developer.notes

import org.springframework.stereotype.Controller
import org.springframework.web.bind.annotation.RequestMapping
import javax.servlet.http.HttpServletRequest

@Controller
class RouteController {

@RequestMapping(value = ["/{path:[^\\.]*}"])
fun redirect(request: HttpServletRequest): String {
return "forward:/"
}
}

修改 SecurityConfiguration.kt 以允许匿名访问静态 Web 文件、/user 信息端点,并添加额外的安全 header 。

package com.okta.developer.notes

import org.springframework.security.config.annotation.web.builders.HttpSecurity
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter
import org.springframework.security.web.csrf.CookieCsrfTokenRepository
import org.springframework.security.web.header.writers.ReferrerPolicyHeaderWriter
import org.springframework.security.web.util.matcher.RequestMatcher

@EnableWebSecurity
class SecurityConfiguration : WebSecurityConfigurerAdapter() {

override fun configure(http: HttpSecurity) {
//@formatter:off
http
.authorizeRequests()
.antMatchers("/**/*.{js,html,css}").permitAll()
.antMatchers("/", "/user").permitAll()
.anyRequest().authenticated()
.and()
.oauth2Login()
.and()
.oauth2ResourceServer().jwt()

http.requiresChannel()
.requestMatchers(RequestMatcher {
r -> r.getHeader("X-Forwarded-Proto") != null
}).requiresSecure()

http.csrf()
.csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())

http.headers()
.contentSecurityPolicy("script-src 'self'; report-to /csp-report-endpoint/")
.and()
.referrerPolicy(ReferrerPolicyHeaderWriter.ReferrerPolicy.SAME_ORIGIN)
.and()
.featurePolicy("accelerometer 'none'; camera 'none'; microphone 'none'")

//@formatter:on
}
}

创建一个 UserController.kt 可用于确定用户是否已登录。

package com.okta.developer.notes

import org.springframework.security.core.annotation.AuthenticationPrincipal
import org.springframework.security.oauth2.core.oidc.user.OidcUser
import org.springframework.web.bind.annotation.GetMapping
import org.springframework.web.bind.annotation.RestController

@RestController
class UserController() {

@GetMapping("/user")
fun user(@AuthenticationPrincipal user: OidcUser?): OidcUser? {
return user;
}
}

以前,Angular 处理注销。添加一个 LogoutController,它将处理 session 过期以及将信息发送回 Angular,以便它可以从 Okta 注销。

package com.okta.developer.notes

import org.springframework.http.ResponseEntity
import org.springframework.security.core.annotation.AuthenticationPrincipal
import org.springframework.security.oauth2.client.registration.ClientRegistration
import org.springframework.security.oauth2.client.registration.ClientRegistrationRepository
import org.springframework.security.oauth2.core.oidc.OidcIdToken
import org.springframework.web.bind.annotation.PostMapping
import org.springframework.web.bind.annotation.RestController
import javax.servlet.http.HttpServletRequest

@RestController
class LogoutController(val clientRegistrationRepository: ClientRegistrationRepository) {

val registration: ClientRegistration = clientRegistrationRepository.findByRegistrationId("okta");

@PostMapping("/api/logout")
fun logout(request: HttpServletRequest,
@AuthenticationPrincipal(expression = "idToken") idToken: OidcIdToken): ResponseEntity<*> {
val logoutUrl = this.registration.providerDetails.configurationMetadata["end_session_endpoint"]
val logoutDetails: MutableMap<String, String> = HashMap()
logoutDetails["logoutUrl"] = logoutUrl.toString()
logoutDetails["idToken"] = idToken.tokenValue
request.session.invalidate()
return ResponseEntity.ok().body<Map<String, String>>(logoutDetails)
}
}

最后,我将 Gradle 配置为构建一个包含 Angular 的 JAR。

首先导入 NpmTask 并在 build.gradle.kts 中添加 Node Gradle 插件:

import com.moowork.gradle.node.npm.NpmTask

plugins {
...
id("com.github.node-gradle.node") version "2.2.4"
...
}

然后,定义 Angular 应用的位置和 Node 插件的配置。

val spa = "${projectDir}/../notes";

node {
version = "12.16.2"
nodeModulesDir = file(spa)
}

添加一个buildWeb任务:

val buildWeb = tasks.register<NpmTask>("buildNpm") {
dependsOn(tasks.npmInstall)
setNpmCommand("run", "build")
setArgs(listOf("--", "--prod"))
inputs.dir("${spa}/src")
inputs.dir(fileTree("${spa}/node_modules").exclude("${spa}/.cache"))
outputs.dir("${spa}/dist")
}

并修改processResources任务,在传入-Pprod时构建Angular。

tasks.processResources {
rename("application-${profile}.properties", "application.properties")
if (profile == "prod") {
dependsOn(buildWeb)
from("${spa}/dist/notes") {
into("static")
}
}
}

现在您应该能够使用 ./gradlew bootJar -Pprod 组合这两个应用程序,或者使用 ./gradlew bootRun -Pprod 查看它们的运行。
