第九章 SpringCloud Oauth2认证中心-Zuul网关上添加认证

本章完整源码地址：https://github.com/kwang2003/springcloud-study-ch09.git

1.项目概要

这一章节的内容以第七章的代码为基础改造而成https://github.com/kwang2003/springcloud-study-ch08.git。

通过第八章的学习，我们已经已经基于JWT升级了OAuth2认证服务器，在这个章节中，我们将给之前的zuul网关上加上OAuth2认证功能，让所有的访问都经过一次安全认证后才能继续。系统架构和上章一样，保持不变



2.OAuth2项目改动

a)为oauth2项目增加/uaa访问上下文

了配置以后，oauth2工程的访问地址就要加上/uaa这个上下文了，加这个上下文主要是为后一个步骤做转发规则使用

server.context-path=/uaa



b)获取public key

通过查看JwtAccessTokenConverter的源码了解到，vertify key 是对publicKey进行Base64编码后得到的一个字符串：



增加一个测试类PublicKeyTest，按照规则生成这个字符串，代码如下：



得到输出的key结果是

-----BEGIN PUBLIC KEY-----

MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoZQfHaHQEzGuWBESlrcoM9DMiVM/fHEjLG7VK3COZ1xuM49P4pC+pNY3nm+wL/WM8QQdYNjPetzCiltLdW60rQa/+osW599SkmUSGF7rYXI9y4n1N4h0k9jLBdZ9n2/5miWWPDwrbsIGgLXp/NIsH4T2Gj6lUZuMj4cskIjU8P12S5TJEQ3N+PGYBY+G8zWzYB1dr3LssqATOqv1/XH+kPEesAtaaxJsfa/SWpaxDZnM5JGSjQ1/FEjyF2e0yAKbV/NqHnIqqnucr/StFBn/sGloEs1DAj8nIMtoiklqejqJvjCSdOC75f2N3iK72DgAVZkSNtfEdsVygHiOOtBtWQIDAQAB

-----END PUBLIC KEY-----

3.网关项目改造springcloud-zuul

a)增加spring-cloud-starter-oauth2和jwt

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-starter-oauth2</artifactId>

</dependency>

<dependency>

<groupId>org.springframework.security</groupId>

<artifactId>spring-security-jwt</artifactId>

</dependency>

b)修改系统配置项

新增jwt和oauth2的安全认证相关配置，如下

security.basic.enabled=false

security.oauth2.sso.loginPath=/login

security.oauth2.client.accessTokenUri=http://oauth2/uaa/oauth/token

security.oauth2.client.userAuthorizationUri=/uaa/oauth/authorize

security.oauth2.client.clientId=client

security.oauth2.client.clientSecret=secret

security.oauth2.resource.jwt.keyValue=\

-----BEGIN PUBLIC KEY-----\

MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAoZQfHaHQEzGuWBESlrcoM9DMiVM/fHEjLG7VK3COZ1xuM49P4pC+pNY3nm+wL/WM8QQdYNjPetzCiltLdW60rQa/+osW599SkmUSGF7rYXI9y4n1N4h0k9jLBdZ9n2/5miWWPDwrbsIGgLXp/NIsH4T2Gj6lUZuMj4cskIjU8P12S5TJEQ3N+PGYBY+G8zWzYB1dr3LssqATOqv1/XH+kPEesAtaaxJsfa/SWpaxDZnM5JGSjQ1/FEjyF2e0yAKbV/NqHnIqqnucr/StFBn/sGloEs1DAj8nIMtoiklqejqJvjCSdOC75f2N3iK72DgAVZkSNtfEdsVygHiOOtBtWQIDAQAB\

-----END PUBLIC KEY-----

security.oauth2.resource.id=zuul

security.oauth2.resource.serviceId=${PREFIX:}zuul

其中红色高亮部分为上个步骤通过PublicKeyTest输出的结果

c)设置ZuulApplication为ResourceServer

Oauth2中包含四个核心角色

Resource Owner ----通常是用户，如张三

Resource Server ----资源服务器，存放具体的数据，在这个项目里是Zuul（实际上是各个微服务，但是我们使用Zuul统一代理了，所以就把Resource Server设置在Zuul上了，这也是增加Zuul这一层的意义所在--我们不需要给每个微服务重复的去添加这些配置，而是在Zuul统一出口的地方添加一次就可以了）

Authorization Server ----认证服务器，这个项目里是springcloud-oauth2服务

Client ---需要使用OAuth2服务器进行集成的第三方应用，如我们的网站rrs.com要使用qq联合登录，那么rrs.com就是一个客户端Client,在项目中，client的信息定义在内存中了



使ZuulApplication成为ResourceServer非常简单，在类上增加@EnableResourceServer注解：

package com.pachiraframework.springcloud.zuul;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;

@EnableZuulProxy

@EnableResourceServer

@EnableDiscoveryClient

@SpringBootApplication

public class ZuulApplication {

public static void main(String[] args) {

SpringApplication.run(ZuulApplication.class, args);

}

}

并且要增加一个UserInfoRestTemplate的bean

@Bean

UserInfoRestTemplateCustomizer userInfoRestTemplateCustomizer(LoadBalancerInterceptor loadBalancerInterceptor) {

return template -> {

List<ClientHttpRequestInterceptor> interceptors = new ArrayList<>();

interceptors.add(loadBalancerInterceptor);

AccessTokenProviderChain accessTokenProviderChain = Stream

.of(new AuthorizationCodeAccessTokenProvider(), new ImplicitAccessTokenProvider(),

new ResourceOwnerPasswordAccessTokenProvider(), new ClientCredentialsAccessTokenProvider())

.peek(tp -> tp.setInterceptors(interceptors))

.collect(Collectors.collectingAndThen(Collectors.toList(), AccessTokenProviderChain::new));

template.setAccessTokenProvider(accessTokenProviderChain);

};

}



d)增加一个DynamicOauth2ClientContextFilter



f)增加安全配置SecurityConfiguration

package com.pachiraframework.springcloud.zuul.config;

return oAuth2AuthenticationManager;

}

private RequestMatcher csrfRequestMatcher() {

return new RequestMatcher() {

// Always allow the HTTP GET method

private final Pattern allowedMethods = Pattern.compile("^(GET|HEAD|OPTIONS|TRACE)$");

// Disable CSFR protection on the following urls:

private final AntPathRequestMatcher[] requestMatchers = { new AntPathRequestMatcher("/uaa/**") };

@Override

public boolean matches(HttpServletRequest request) {

if (allowedMethods.matcher(request.getMethod()).matches()) {

return false;

}

for (AntPathRequestMatcher matcher : requestMatchers) {

return false;

}

}

return true;

}

};

}

private static Filter csrfHeaderFilter() {

return new OncePerRequestFilter() {

@Override

FilterChain filterChain) throws ServletException, IOException {

CsrfToken csrf = (CsrfToken) request.getAttribute(CsrfToken.class.getName());

if (csrf != null) {

Cookie cookie = new Cookie(CSRF_COOKIE_NAME, csrf.getToken());

cookie.setPath("/");

cookie.setSecure(true);

response.addCookie(cookie);

}

};

}

private static CsrfTokenRepository csrfTokenRepository() {

HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository();

repository.setHeaderName(CSRF_HEADER_NAME);

return repository;

}

}

4.测试访问
本机地址是10.130.52.113(使用localhost访问会有问题， 具体原因尚未弄清楚)
