實現原理
在之前的文章中，我們介紹了普通的帳號密碼登錄的方式： SpringBoot + Spring Security 基本使用及個性化登錄配置。 但是現在還有一種常見的方式，就是直接通過手機短信驗證碼登錄，這裡就需要自己來做一些額外的工作了。
對SpringSecurity認證流程詳解有一定了解的都知道，在帳號密碼認證的過程中，涉及到了以下幾個類：UsernamePasswordAuthenticationFilter（用於請求參數獲取），UsernamePasswordAuthenticationToken（表示用戶登錄信息），ProviderManager（進行認證校驗），
因為是通過的短信驗證碼登錄，所以我們需要對請求的參數，認證過程，用戶登錄Token信息進行一定的重寫。
當然驗證碼的過程我們應該放在最前面，如果圖形驗證碼的實現一樣。這樣的做法的好處是：將驗證碼認證該過程解耦出來，讓其他接口也可以使用到。
基本實現
驗證碼校驗
短信驗證碼的功能實現，其實和圖形驗證碼的原理是一樣的。只不過一個是返回給前端一個圖片，一個是給用戶發送短消息，這裡只需要去調用一下短信服務商的接口就好了。更多的原理可以參考SpringBoot + SpringSecurity 實現圖形驗證碼功能
AuthenticationToken
在使用帳號密碼登錄的時候，UsernamePasswordAuthenticationToken裡麵包含了用戶的帳號，密碼，以及其他的是否可用等狀態信息。我們是通過手機短信來做登錄，所以就沒有密碼了，這裡我們就直接將UsernamePasswordAuthenticationToken的代碼copy過來，把密碼相關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
在帳戶密碼登錄的流程中，默認使用的是UsernamePasswordAuthenticationFilter，它的作用是從請求中獲取帳戶、密碼，請求方式校驗，生成AuthenticationToken。這裡我們的參數是有一定改變的，所以還是老方法，copy過來進行簡單的修改
public class SmsCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter { // 請求參數key private String mobileParameter = SecurityConstants.DEFAULT_PARAMETER_NAME_MOBILE; // 是否只支持POST private boolean postOnly = true; public SmsCodeAuthenticationFilter() { // 請求接口的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()); } // 根據請求參數名，獲取請求value String mobile = obtainMobile(request); if (mobile == null) { mobile = ""; } mobile = mobile.trim(); // 生成對應的AuthenticationToken SmsCodeAuthenticationToken authRequest = new SmsCodeAuthenticationToken(mobile); setDetails(request, authRequest); return this.getAuthenticationManager().authenticate(authRequest); } /** * 獲取手機號*/ protected String obtainMobile(HttpServletRequest request) { return request.getParameter(mobileParameter); } // 省略不相關代碼} Provider
在帳號密碼登錄的過程中，密碼的正確性以及帳號是否可用是通過DaoAuthenticationProvider來校驗的。我們也應該自己實現一個Provier
public class SmsCodeAuthenticationProvider implements AuthenticationProvider { private UserDetailsService userDetailsService; /** * 身份邏輯驗證* @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("無法獲取用戶信息"); } 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
主要的認證流程就是通過以上四個過程實現的， 這裡我們再降它們配置一下就可以了
@Componentpublic 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@Overrideprotected void configure(HttpSecurity http) throws Exception { http.apply(smsCodeAuthenticationSecurityConfig);}代碼下載
