使用 OAuth2 时 Spring-boot 应用程序未进行身份验证（更新 #2）答案

【问题标题】：Spring-boot application not authenticating when using OAuth2 (updated #2)使用 OAuth2 时 Spring-boot 应用程序未进行身份验证（更新 #2）
【发布时间】：2020-05-29 18:13:54
【问题描述】：

我正在尝试创建一个 OAuth2 客户端来访问第三方 OAuth2 服务器。我已将此行添加到我的 application.properties 文件中：

spring.security.oauth2.client.registration.mercadolivre=mercadolivre
spring.security.oauth2.client.registration.mercadolivre.client-id=...
spring.security.oauth2.client.registration.mercadolivre.client-secret=...
spring.security.oauth2.client.registration.mercadolivre.client-authentication-method=basic
spring.security.oauth2.client.registration.mercadolivre.authorization-grant-type=authorization_code
spring.security.oauth2.client.registration.mercadolivre.redirect-uri=http://localhost:8080
spring.security.oauth2.client.provider.mercadolivre.authorization-uri=https://auth.mercadolivre.com.br/authorization
spring.security.oauth2.client.provider.mercadolivre.token-uri=https://auth.mercadolivre.com.br/oauth

我有这个 Spring-security 配置：

@Configuration
@EnableWebSecurity
@EnableOAuth2Sso
public class Security extends WebSecurityConfigurerAdapter {
  @Override
  public void configure(HttpSecurity http) throws Exception {
      http
        .csrf().disable()
        .authorizeRequests()
          .antMatchers("/css/**", "/images/**", "/js/**", "/**").permitAll()
          .anyRequest().authenticated()
        .and()
          .oauth2Login()
        .and()
        .logout()
          .logoutUrl("/logout");
  }
...
}

这个 html 用于我的开放和安全区域：

  <body>
    <ul>
      <!--<li class="navbar-brand">
        <img th:src="@{/img/logo.png}" class="sticky" width="120px" height="120px" alt="logo">
      </li> -->

      <li>
        Loja
      </li>

      <li class="right" sec:authorize="isAnonymous()">
        <a class="button" th:href="@{/oauth2/authorization/mercadolivre}">Entrar</button>
      </li>

      <li sec:authorize="isAuthenticated()">
        Logged in as: <span sec:authentication="name">Bob</span>
      </li>

      <li class="right" sec:authorize="isAuthenticated()">
        <a class="button" th:href="@{/logout}">Sair</button>
      </li>
    </ul>
  </body>

但是当我在浏览器上打开应用程序并尝试登录时，我会正确转发到授权页面，但是当我重定向回我的应用程序时，我没有通过身份验证。

任何人都可以看到这里出了什么问题？

更新

在我将 spring-security 配置更改为此之后

@Configuration
@EnableWebSecurity
@EnableOAuth2Sso
public class Security extends WebSecurityConfigurerAdapter {
  @Override
  public void configure(HttpSecurity http) throws Exception {
      http
        .csrf().disable()
        .authorizeRequests()
          .antMatchers("/css/**", "/images/**", "/js/**", "/**").permitAll()
          .anyRequest().authenticated()
        .and()
        .formLogin()
          .loginPage("/login")
          .loginProcessingUrl("/doLogin").permitAll()
        .and()
        .oauth2Login()
          .loginPage("/login")
          .loginProcessingUrl("/login/oauth")
        .and()
        .logout()
          .logoutUrl("/logout");
  }
...
}

和application.propertiesredirect_uri 到这个：

spring.security.oauth2.client.registration.mercadolivre.redirect-uri=http://localhost:8080/login/oauth

现在，当我尝试登录时出现此错误：

（重定向网址看起来不错，包括附加的必要代码：http://localhost:8080/login/oauth?code=...&state=...）

更新 2

我当前的设置如下。有了这个，我被转发到服务授权页面，但是当我返回我的项目时，我没有通过身份验证（获取访问令牌的授权代码成功附加到 url）。

App.java

@EnableOAuth2Client
@EnableOAuth2Sso
@SpringBootApplication
@RestController
public class App extends WebSecurityConfigurerAdapter {

    @GetMapping("/user")
    public Map<String, Object> user(@AuthenticationPrincipal OAuth2User principal) {
            return Collections.singletonMap("name", principal.getAttribute("name"));
    }

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
            http
                    .authorizeRequests(a -> a
                            .antMatchers("/", "/error", "/webjars/**", "/css/**", "/js/**", "/img/**").permitAll()
                            .anyRequest().authenticated()
                    )
                    .exceptionHandling(e -> e
                            .authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED))
                    )
                    .csrf(c -> c
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())
            )
                    .logout(l -> l
                        .logoutSuccessUrl("/").permitAll()
                    )
                    .oauth2Login();
    }

}

【问题讨论】：

标签： spring spring-boot oauth oauth-2.0 spring-oauth2

【解决方案1】：

我认为 OAuth2 客户端的重定向 Uri 应该设置为：

spring.security.oauth2.client.registration.mercadolivre.redirect-uri=http://localhost:8080/login/oauth2/mercadolivre

并且这个相同的 URI 应该作为重定向 URL 输入到您的第三方 OAuth2 授权服务器中，因为这是授权服务器应该发送 Spring 安全的授权代码以最终获取令牌的地方。

【讨论】：

好的，我按照您的建议修改了我的 spring-security 配置和 application.properties 文件，现在我收到了 NullPointerException（我用详细信息更新了问题）。什么都没有改变。你能看到我现在缺少什么吗？
这里有更详细的描述github.com/spring-projects/spring-security/tree/master/samples/…
这个我试过了，也不行。如果我只是将 application.properties redirect-uri 属性更改为http://localhost:8080/login/oauth2/mercadolivre，则会出现 404 错误，如果我将 spring-security 配置类中的 oauth2login().loginProcessingUrl(...) 更改为该属性，则会出现 NullPointerException 错误。
我也尝试完全删除oauth2login.loginProcessingUrl(...)，但也不起作用（出现 NullPointerException 错误）。
如果您在没有任何登录参数的情况下尝试第一个 WebSecurityConfigurerAdapter 会发生什么
