SpringBoot + SpringSecurity 短信验证码登录功能实现
作者:whyalwaysmea 时间:2022-10-16 10:26:25
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);
}
