spring - 运行时未调用自定义弹簧安全过滤器

问题描述

我正在尝试在 Spring Boot Rest 服务项目中启用 Spring Security，但遇到了一些问题。

我用这段代码配置了它

@Configuration
@EnableWebSecurity
public class WebSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    private LdapAuthenticationProvider ldapAuthenticationProvider;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .httpBasic().and()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }


    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.authenticationProvider(ldapAuthenticationProvider);
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }

}

并实现了一个自定义身份验证提供程序以登录 LDAP（它具有非标准配置，因此我无法使默认 ldap 提供程序工作）

@Component
public class LdapAuthenticationProvider implements AuthenticationProvider {

    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {

        String email = authentication.getName();
        String password = authentication.getCredentials().toString();

        LdapConnection ldap = new LdapConnection();
        String uid = ldap.getUserUID(email);
        if(uid == null || uid == ""){
            throw new BadCredentialsException("User " + email + " not found");
        }

        if(ldap.login(uid, password)){

            return new UsernamePasswordAuthenticationToken(uid, null, new ArrayList<>());
        }else{
            throw new BadCredentialsException("Bad credentials");
        }
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return true;  
        //To indicate that this authenticationprovider can handle the auth request. since there's currently only one way of logging in, always return true

    }

}

这段代码运行良好，因为使用基本授权标头调用我的服务，它能够正确登录并返回调用的服务。当我尝试插入不同的授权/身份验证时，问题就开始了。我不想使用基本身份验证，而是想从我的反应前端中的表单传递凭据，所以我想在 POST 调用中将它们作为 json 主体传递。（想法是生成一个 jwt 令牌并将其用于以下通信）。

所以我将配置方法更改为：

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable().authorizeRequests()
            .anyRequest().authenticated()
            .and()
            .addFilter(new JWTAuthenticationFilter(authenticationManager()))
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
    }

并定义了一个自定义身份验证过滤器：

public class JWTAuthenticationFilter extends
        UsernamePasswordAuthenticationFilter {

    @Autowired
    private AuthenticationManager authenticationManager;

    public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res) throws AuthenticationException{
        String requestBody;
        try{
            requestBody = IOUtils.toString(req.getReader());
            JsonParser jsonParser = JsonParserFactory.getJsonParser();
            Map<String, Object> requestMap = jsonParser.parseMap(requestBody);
            return authenticationManager.authenticate( new UsernamePasswordAuthenticationToken(requestMap.get("email"), requestMap.get("password"), new ArrayList<>()));
        }catch(IOException e){
            throw new InternalAuthenticationServiceException("Something goes wrong parsing the request body",e );
        }
    }

    @Override
    protected void successfulAuthentication(HttpServletRequest req, HttpServletResponse res, FilterChain chain, Authentication auth) throws IOException{

        JwtTokenProvider tokenProvider = new JwtTokenProvider();
        String token = tokenProvider.generateToken(auth.getPrincipal().toString());
        Cookie cookie = new Cookie("jwt",token);
        cookie.setHttpOnly(true);
        cookie.setSecure(true);
        res.addCookie(cookie);

    }

}

问题是，无论我在做什么，运行时似乎根本没有进入这个过滤器。我错过了什么？我想这是一件大而愚蠢的事情，但我无法弄清楚......

更新：问题似乎是 UsernamePassWordAuthenticationFilter 只能通过表单调用。然后，我将代码更改为扩展 AbstractAuthenticationProcessingFilter。

修改后的过滤器：

public class JWTAuthenticationFilter extends
        AbstractAuthenticationProcessingFilter {


    private AuthenticationManager authenticationManager;

    public JWTAuthenticationFilter(AuthenticationManager authenticationManager) {
        super("/api/secureLogin");
        this.authenticationManager = authenticationManager;
    }

    @Override
    public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res) throws AuthenticationException{
        String requestBody;
        try{
            requestBody = IOUtils.toString(req.getReader());
            JsonParser jsonParser = JsonParserFactory.getJsonParser();
            Map<String, Object> requestMap = jsonParser.parseMap(requestBody);
            UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(requestMap.get("email"), requestMap.get("password"), new ArrayList<>()); 
            return authenticationManager.authenticate(token);
        }catch(IOException e){
            throw new InternalAuthenticationServiceException("Something goes wrong parsing the request body",e );
        }
    }
}

以及修改后的配置方法：

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.csrf().disable().authorizeRequests()
        .antMatchers(HttpMethod.POST, "/api/secureLogin").permitAll()
        .antMatchers(HttpMethod.GET, "/api").permitAll()
        .antMatchers("/api/**").authenticated()
        .and()
        .addFilterBefore(new JWTAuthenticationFilter(authenticationManager()), UsernamePasswordAuthenticationFilter.class)
        .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
}
