NoOpPasswordEncoder不工作，返回状态码200而不是401

Question

我试图通过spring boot学习Spring Security的基础知识，我创建了一个项目，其中还包括postgresql设置。Postgresql部分按预期工作。

问题是，在我通过正确的凭据访问安全endpoint后，我只是试图使用正确的用户名和错误的密码进行访问，并期待401错误，但返回200。并返回endpoint的内容。

• 如果我使用用户名：dummy_user和密码：12345进行基本身份验证请求，则响应为401 UnAuthorized
• 如果我使用用户名：dummy_user和密码：1234进行基本身份验证请求，响应为200
• 如果我使用用户名：dummy_user和密码：1234进行基本身份验证请求，响应为200
• 响应200后，如果我使用用户名：dummy_user和密码：12345进行基本身份验证请求，响应为200

在运行项目之前，我刚刚添加了一个虚拟用户：

INSERT INTO test_users (username,password) VALUES ('dummy_user','1234');

DTO很简单：

@Entity
@Table(name = "test_users")
public class UserDTO {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column(name = "username")
    private String username;

    @Column(name = "password")
    private String password;

• 配置类：

@Configuration
public class ProjectBeanConfiguration {
    @Bean
    public UserDetailsService userDetailsService(){
       return new PostgresqlUserDetailsService();
    }

    @Bean
    public PasswordEncoder passwordEncoder(){
        return NoOpPasswordEncoder.getInstance();
    }
}

• 和用户详细信息服务：

public class PostgresqlUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username){
        Optional<UserDTO> userDTOOptional = userRepository.findUserByUsername(username);
        UserDTO userInDb = userDTOOptional.orElseThrow(() -> new UsernameNotFoundException("Not Found in DB"));
        SecureUser secureUser = new SecureUser(userInDb);
        return secureUser;
    }
}

• SecureUser什么都不是，只是将UserDTO映射到UserDetails：

java prettyprint-override">public class SecureUser  implements UserDetails {

    private final UserDTO userDTO;

    public SecureUser(UserDTO userDTO) {
        this.userDTO = userDTO;
    } 
    // ...
    @Override
    public String getPassword() {
        return userDTO.getPassword();
    }

    @Override
    public String getUsername() {
        return userDTO.getUsername();
    }
    // ...

• 只有一个控制器：

@RestController
public class HelloController {

    @GetMapping("/hello")
    public String hello(){
        return "hello";
    }
}

• Logs for：后响应200，如果我做一个基本的身份验证请求用户名：dummy_user和密码：12345，响应是200：

Answer 1

您第一次使用正确的用户名和密码登录Spring Security将创建一个会话对象并为您提供一个会话cookie。会话对象是存储信息的对象。当您第一次登录时，它会创建一个身份验证令牌，表示您已成功登录，并将其存储在会话对象中。每次您访问Web应用程序上的安全endpoint时，您都会发送会话cookie。cookie将您标识为已被登录。要删除会话cookie，请转到注销终端url，这将删除您的会话。

Answer 2

根据日志：

SecurityContextHolder not populated with anonymous token, as it already contained: 'org.springframework.security.authentication.UsernamePasswordAuthenticationToken@8e885cc7: Principal

这表明当您访问hello时，上下文中已经有一个主体。

然后日志告诉我们：

Previously Authenticated

所以我的结论（因为这不是完整的日志），我们还没有看到您是如何完成您的请求的，如下所示：

// No session established, you provide wrong credentials, you get a 401
 - If I do a basic authentication request with username: dummy_user and password: 12345, response is 401 UnAuthorized

// You authenticate correctly, we establish a session, you get a session cookie
- If I do a basic authentication request with username: dummy_user and password: 1234, response is 200

// You provide the session cookie in your request, we get a 200OK
- If I do a basic authentication request with username: dummy_user and password: 1234, response is 200

// You still provide the session cookie, we get a 200OK 
- After response 200, If I do a basic authentication request with username: dummy_user and password: 12345, response is 200

如果你想确认这个理论，你应该在每次登录尝试之间/logout，或者删除设置好的cookie。
