为什么我会收到 403 - 禁止

Question

我正在开发 Spring Boot Security 项目，我在一些端点上进行了身份验证，以防止用户访问，并在我点击此 URL 时向 ADMIN 授予权限：admin/users。我得到了登录页面，我输入了凭据，而不是返回它返回的实际内容：

类型=禁止，状态=403

这是我的安全配置：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    // inject spring user details interface
    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService).passwordEncoder(encoder());
    }
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable();
        http.authorizeRequests()
                .antMatchers("/api/**" , "/").permitAll()
                .antMatchers("/admin/**").hasRole("ADMIN")
                .anyRequest().authenticated()
                .and().formLogin();
    }
    @Bean
    public BCryptPasswordEncoder encoder(){
        return new BCryptPasswordEncoder();
    }

}

管理员用户控制器：

@RestController
@RequestMapping("admin/users")
public class UserController {
    //
    @Autowired
    private UserRepository userRepository;
    @Autowired
    private BCryptPasswordEncoder passwordEncoder;

   //  get all users
    @PreAuthorize("hasAnyRole('ADMIN')")
    @GetMapping
    public List<User> getAllUsers(){
        return userRepository.findAll();
    }

    // test
    @PreAuthorize("hasAnyRole('ADMIN')")
    @GetMapping("/test")
    public String message() {
        return "secured end point";
    }

    //create new users
    @PreAuthorize("hasAnyRole('ADMIN')")
    @PostMapping
    public User registerUser(@RequestBody  User user){
        
        String password = user.getPassword();
        String encodedPassword = passwordEncoder.encode(password);
        user.setPassword(encodedPassword);
        return userRepository.save(user);
    }
}

用户详细信息：

public class CustomUserDetails implements UserDetails {

    /**
     * 
     */
    private static final long serialVersionUID = 1256711395932122675L;
    private User user;

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        
        return user.getRoles().stream().map(role -> new SimpleGrantedAuthority("ROLE_" + role))
                .collect(Collectors.toList());

    }

    @Override
    public String getPassword() {
        return user.getPassword();
    }

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

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        // TODO Auto-generated method stub
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        // TODO Auto-generated method stub
        return true;
    }

    @Override
    public boolean isEnabled() {
        // TODO Auto-generated method stub
        return true;
    }

}

用户详细信息服务：

[![@Service
public class CustomUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
      User user = userRepository.findByUsername(username);
      CustomUserDetail userDetail = null;

      if(user != null) {
        userDetail = new CustomUserDetail();
        userDetail.setUser(user);
      }
      else {
          throw new UsernameNotFoundException("user not exist with username " + username);
      }
        System.out.println("user details" + userDetail);
        return  userDetail;

    }

Answer 1

我通过简单地更正 getAuthorities() 解决了这个问题，我删除了

simpleGrantedAuthority()

中的“ROLE_”，将返回值提取到 userDetail.java 中的变量中，并使用

hasAuthority()

而不是

hasRole()

。

收到 403 错误的代码 - 禁止：

@Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        
        return user.getRoles().stream().map(role -> new SimpleGrantedAuthority("ROLE_" + role))
                .collect(Collectors.toList());

    }

解决方案：

 @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {

        List<SimpleGrantedAuthority> authorities = user.getRoles().stream().map(role -> 
                        new SimpleGrantedAuthority(role.getRole()))
                .collect(Collectors.toList());
        return authorities;
    }
