SpringBoot + SpringSecurity 短信验证码登录功能实现
实现原理
在之前的文章中,我们介绍了普通的帐号密码登录的方式: SpringBoot + Spring Security 基本使用及个性化登录配置。 但是现在还有一种常见的方式,就是直接通过手机短信验证码登录,这里就需要自己来做一些额外的工作了。
对SpringSecurity认证流程详解有一定了解的都知道,在帐号密码认证的过程中,涉及到了以下几个类:UsernamePasswordAuthenticationFilter(用于请求参数获取),UsernamePasswordAuthenticationToken(表示用户登录信息),ProviderManager(进行认证校验),
因为是通过的短信验证码登录,所以我们需要对请求的参数,认证过程,用户登录Token信息进行一定的重写。
当然验证码的过程我们应该放在最前面,如果图形验证码的实现一样。这样的做法的好处是:将验证码认证该过程解耦出来,让其他接口也可以使用到。
基本实现
验证码校验
短信验证码的功能实现,其实和图形验证码的原理是一样的。只不过一个是返回给前端一个图片,一个是给用户发送短消息,这里只需要去调用一下短信服务商的接口就好了。更多的原理可以参考 SpringBoot + SpringSecurity 实现图形验证码功能
AuthenticationToken
在使用帐号密码登录的时候,UsernamePasswordAuthenticationToken里面包含了用户的帐号,密码,以及其他的是否可用等状态信息。我们是通过手机短信来做登录,所以就没有密码了,这里我们就直接将UsernamePasswordAuthenticationToken的代码copy过来,把密码相关的信息去掉就可以了
public class SmsCodeAuthenticationToken extends AbstractAuthenticationToken { private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID; private final Object principal; public SmsCodeAuthenticationToken(String mobile) { super(null); this.principal = mobile; setAuthenticated(false); } public SmsCodeAuthenticationToken(Object principal, Collection<? extends GrantedAuthority> authorities) { super(authorities); this.principal = principal; super.setAuthenticated(true); // must use super, as we override } public Object getCredentials() { return null; } public Object getPrincipal() { return this.principal; } public void setAuthenticated(boolean isAuthenticated) throws IllegalArgumentException { if (isAuthenticated) { throw new IllegalArgumentException( "Cannot set this token to trusted - use constructor which takes a GrantedAuthority list instead"); } super.setAuthenticated(false); } @Override public void eraseCredentials() { super.eraseCredentials(); } }
AuthenticationFilter
在帐户密码登录的流程中,默认使用的是UsernamePasswordAuthenticationFilter,它的作用是从请求中获取帐户、密码,请求方式校验,生成AuthenticationToken。这里我们的参数是有一定改变的,所以还是老方法,copy过来进行简单的修改
public class SmsCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter { // 请求参数key private String mobileParameter = SecurityConstants.DEFAULT_PARAMETER_NAME_MOBILE; // 是否只支持POST private boolean postOnly = true; public SmsCodeAuthenticationFilter() { // 请求接口的url super(new AntPathRequestMatcher(SecurityConstants.DEFAULT_LOGIN_PROCESSING_URL_MOBILE, "POST")); } public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response) throws AuthenticationException { if (postOnly && !request.getMethod().equals("POST")) { throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod()); } // 根据请求参数名,获取请求value String mobile = obtainMobile(request); if (mobile == null) { mobile = ""; } mobile = mobile.trim(); // 生成对应的AuthenticationToken SmsCodeAuthenticationToken authRequest = new SmsCodeAuthenticationToken(mobile); setDetails(request, authRequest); return this.getAuthenticationManager().authenticate(authRequest); } /** * 获取手机号 */ protected String obtainMobile(HttpServletRequest request) { return request.getParameter(mobileParameter); } // 省略不相关代码 }
Provider
在帐号密码登录的过程中,密码的正确性以及帐号是否可用是通过DaoAuthenticationProvider来校验的。我们也应该自己实现一个Provier
public class SmsCodeAuthenticationProvider implements AuthenticationProvider { private UserDetailsService userDetailsService; /** * 身份逻辑验证 * @param authentication * @return * @throws AuthenticationException */ @Override public Authentication authenticate(Authentication authentication) throws AuthenticationException { SmsCodeAuthenticationToken authenticationToken = (SmsCodeAuthenticationToken) authentication; UserDetails user = userDetailsService.loadUserByUsername((String) authenticationToken.getPrincipal()); if (user == null) { throw new InternalAuthenticationServiceException("无法获取用户信息"); } SmsCodeAuthenticationToken authenticationResult = new SmsCodeAuthenticationToken(user, user.getAuthorities()); authenticationResult.setDetails(authenticationToken.getDetails()); return authenticationResult; } @Override public boolean supports(Class<?> authentication) { return SmsCodeAuthenticationToken.class.isAssignableFrom(authentication); } public UserDetailsService getUserDetailsService() { return userDetailsService; } public void setUserDetailsService(UserDetailsService userDetailsService) { this.userDetailsService = userDetailsService; } }
配置
主要的认证流程就是通过以上四个过程实现的, 这里我们再降它们配置一下就可以了
@Component public class SmsCodeAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> { @Autowired private AuthenticationSuccessHandler myAuthenticationSuccessHandler; @Autowired private AuthenticationFailureHandler myAuthenticationFailureHandler; @Autowired private UserDetailsService userDetailsService; @Override public void configure(HttpSecurity http) throws Exception { SmsCodeAuthenticationFilter smsCodeAuthenticationFilter = new SmsCodeAuthenticationFilter(); smsCodeAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class)); smsCodeAuthenticationFilter.setAuthenticationSuccessHandler(myAuthenticationSuccessHandler); smsCodeAuthenticationFilter.setAuthenticationFailureHandler(myAuthenticationFailureHandler); SmsCodeAuthenticationProvider smsCodeAuthenticationProvider = new SmsCodeAuthenticationProvider(); smsCodeAuthenticationProvider.setUserDetailsService(userDetailsService); http.authenticationProvider(smsCodeAuthenticationProvider) .addFilterAfter(smsCodeAuthenticationFilter, UsernamePasswordAuthenticationFilter.class); } } // BrowerSecurityConfig.java @Override protected void configure(HttpSecurity http) throws Exception { http.apply(smsCodeAuthenticationSecurityConfig); }
