当我尝试发布到我的 spring api 时 403 被禁止? [英] 403 forbidden when I try to post to my spring api?

问题描述

使用邮递员，我可以通过一个 get 请求获取用户列表:http://localhost:8080/users.

Using postman, I can get a list of users with a get request to: http://localhost:8080/users.

但是当我向同一个地址发送 post 请求时，我收到了 403 错误.

But when I send a post request to the same address, I get a 403 error.

@RestController
public class UserResource {

    @Autowired
    private UserRepository userRepository;

    @GetMapping("/users")
    public List<User> retrievaAllUsers() {
        return userRepository.findAll();
    }


        @PostMapping("/users")
        public ResponseEntity<Object> createUser(@RequestBody User user) {
            User savedUser = userRepository.save(user);

            URI location = ServletUriComponentsBuilder.fromCurrentRequest()
                    .path("/{id}")
                    .buildAndExpand(savedUser.getId())
                    .toUri();

            return ResponseEntity.created(location).build();

        }


    }


@EnableWebSecurity
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    /*@Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(userDetailsService)
                .passwordEncoder(new BCryptPasswordEncoder());
    }*/


    /*@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.httpBasic().and().authorizeRequests()
                .antMatchers("/users/**").hasRole("ADMIN")
                .and().csrf().disable().headers().frameOptions().disable();
    }*/
}

@Entity
@Table(name = "user")
public class User {

    @Id
    @GeneratedValue
    private Long id;
    private String name;
    private String password;
    @Enumerated(EnumType.STRING)
    private Role role;

    // TODO which cna be removed

    public User() {
        super();
    }

    public User(Long id, String name, String password, Role role) {
        this.id = id;
        this.name = name;
        this.password = password;
        this.role = role;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Role getRole() {
        return role;
    }

    public void setRole(Role role) {
        this.role = role;
    }
}





    @Repository
    public interface UserRepository extends JpaRepository<User, Long> {


    }






INSERT INTO user VALUES (1, 'user1', 'pass1', 'ADMIN'); 
INSERT INTO user VALUES (2, 'user2', 'pass2', 'USER'); 
INSERT INTO user VALUES (3,'user3', 'pass3', 'ADMIN')

添加了删除，但它也给出了403?

added delete, but it also gives a 403?

@DeleteMapping("/users/{id}")

public void deleteUser(@PathVariable long id) {userRepository.deleteById(id);}

public void deleteUser(@PathVariable long id) { userRepository.deleteById(id); }

@EnableWebSecurity
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)

    public class SecurityConfig extends WebSecurityConfigurerAdapter {


        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http.authorizeRequests()
                    .antMatchers("/users/**").permitAll();

        }
    }



@Configuration
@EnableAutoConfiguration
@ComponentScan
public class Application extends SpringBootServletInitializer {

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


}

推荐答案

@EnableWebSecurity 启用 spring 安全性，默认启用 csrf 支持，您必须禁用它才能以防止 403 错误.

@EnableWebSecurity enables spring security and it by default enables csrf support, you must disable it in order to prevent 403 errors.

@Override
protected void configure(HttpSecurity http) throws Exception {
     http.csrf().disable();
}

或者在每个请求中发送 csrf 令牌.

Or send csrf token with each request.

注意:禁用 csrf 会降低应用程序的安全性，最好的办法是发送 csrf 令牌.

Note: disabling csrf makes application less secure, best thing to do is send csrf token.
