### client(客户端) （改篇文章尚未修改，仅供参考） ###

*  OAuth2 客户端的实现方式没有太多任何规定，可自行编写登录逻辑
 *  也可使用 OAuth2 提供的 **@EnableOAuth2Sso** 注解实现单点登录，该注解会添加身份验证过滤器替我们完成所有操作，只需在配置文件里添加授权服务器和资源服务器的配置即可

> 添加配置

server:
      port: 8083
    security:
      oauth2:
        sso:
          loginPath: /login   # 登录路径
        client:
          clientId: client
          clientSecret: secret
          userAuthorizationUri: http://localhost:8081/oauth/authorize
          access-token-uri: http://localhost:8081/oauth/token
        resource:
          userInfoUri: http://localhost:8082/user

> 添加 Security 配置，并启动 @EnableOAuthSso

@Configuration
    @EnableOAuth2Sso
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.
                    // 禁用 CSRF 跨站伪造请求，便于测试
                    csrf().disable()
                    // 验证所有请求
                    .authorizeRequests()
                    .anyRequest()
                    .authenticated()
                    //允许访问首页
                    .antMatchers("/","/login").permitAll()
                    .and()
                    // 设置登出URL为 /logout
                    .logout().logoutUrl("/logout").permitAll()
                    .logoutSuccessUrl("/")
                    .and()
                    .sessionManagement()
                    .sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        }
    }

> 下面是测试用的控制类

@RestController
    public class HelloController {
    
        @GetMapping("/")
        public String welcome() {
            return "welcome";
        }
    
    }

*  测试

> 访问 localhost:9007/login

> 但此时会出现 Authentication Failed: Could not obtain access token

*  上面问题我查找了下，以下是某网友给出的答复

> Centinul as you've figured out this happens due to a cookie conflict, unfortunately cookies don't respect the port numbers. And so both Apps interfere with each other since both are setting JSESSIONID. There are two easy workarounds:

1. use server.context-path to move each App to different paths, note that you need to do this for both
    2. set the server.session.cookie.name for one App to something different, e.g., APPSESSIONID

> I would suggest to put this workaround in a profile that you activate for localhost only.

*  修改配置文件，添加以下内容

# SESSION COOKIE 冲突 
    session:
    cookie:
    name: APPSESSIONID
