Spring Security 实现短信验证码登录功能

之前文章都是基于用户名密码登录，第六章图形验证码登录其实还是用户名密码登录，只不过多了一层图形验证码校验而已；Spring Security默认提供的认证流程就是用户名密码登录，整个流程都已经固定了，虽然提供了一些接口扩展，但是有些时候我们就需要有自己特殊的身份认证逻辑，比如用短信验证码登录，它和用户名密码登录的逻辑是不一样的，这时候就需要重新写一套身份认证逻辑。

开发短信验证码接口

获取验证码

短信验证码的发送获取逻辑和图片验证码类似，这里直接贴出代码。

@GetMapping("/code/sms")
	public void createSmsCode(HttpServletRequest request, HttpServletResponse response) throws Exception {
		// 创建验证码
		ValidateCode smsCode = createCodeSmsCode(request);
		// 将验证码放到session中
		sessionStrategy.setAttribute(new ServletWebRequest(request), SMS_CODE_SESSION_KEY, smsCode);
		String mobile = ServletRequestUtils.getRequiredStringParameter(request, "mobile");
		// 发送验证码
		smsCodeSender.send(mobile, smsCode.getCode());
	}

前端代码

<tr>
				<td>手机号:</td>
				<td><input type="text" name="mobile" value="13012345678"></td>
			</tr>
			<tr>
				<td>短信验证码:</td>
				<td>
					<input type="text" name="smsCode">
					<a href="/code/sms?mobile=13012345678" rel="external nofollow" >发送验证码</a>
				</td>
			</tr>

短信验证码流程原理

短信验证码登录和用户名密码登录对比

步骤流程

• 首先点击登录应该会被SmsAuthenticationFilter过滤器处理，这个过滤器拿到请求以后会在登录请求中拿到手机号，然后封装成自定义的一个SmsAuthenticationToken（未认证）。
• 这个Token也会传给AuthenticationManager，因为AuthenticationManager整个系统只有一个，它会检索系统中所有的AuthenticationProvider，这时候我们要提供自己的SmsAuthenticationProvider，用它来校验自己写的SmsAuthenticationToken的手机号信息。
• 在校验的过程中同样会调用UserDetailsService，把手机号传给它让它去读用户信息，去判断是否能登录，登录成功的话再把SmsAuthenticationToken标记为已认证。
• 到这里为止就是短信验证码的认证流程，上面的流程并没有提到校验验证码信息，其实它的验证流程和图形验证码验证流程也是类似，同样是在SmsAuthenticationFilter过滤器之前加一个过滤器来验证短信验证码。

代码实现

SmsCodeAuthenticationToken

• 作用：封装认证Token
• 实现：可以继承AbstractAuthenticationToken抽象类，该类实现了Authentication接口

public class SmsCodeAuthenticationToken extends AbstractAuthenticationToken {
	private static final long serialVersionUID = SpringSecurityCoreVersion.SERIAL_VERSION_UID;
	private final Object principal;
	/**
	 * 进入SmsAuthenticationFilter时，构建一个未认证的Token
	 *
	 * @param mobile
	 */
	public SmsCodeAuthenticationToken(String mobile) {
		super(null);
		this.principal = mobile;
		setAuthenticated(false);
	}
	/**
	 * 认证成功以后构建为已认证的Token
	 *
	 * @param principal
	 * @param authorities
	 */
	public SmsCodeAuthenticationToken(Object principal,
			Collection<? extends GrantedAuthority> authorities) {
		super(authorities);
		this.principal = principal;
		super.setAuthenticated(true);
	}
	@Override
	public Object getCredentials() {
		return null;
	}
	@Override
	public Object getPrincipal() {
		return this.principal;
	}
	@Override
	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();
	}
}

SmsCodeAuthenticationFilter

• 作用：处理短信登录的请求，构建Token，把请求信息设置到Token中。
• 实现：该类可以模仿UsernamePasswordAuthenticationFilter类，继承AbstractAuthenticationProcessingFilter抽象类

public class SmsCodeAuthenticationFilter extends AbstractAuthenticationProcessingFilter {
	private String mobileParameter = "mobile";
	private boolean postOnly = true;
 /**
 * 表示要处理的请求路径
 */
	public SmsCodeAuthenticationFilter() {
 super(new AntPathRequestMatcher("/authentication/mobile", "POST"));
	}
 @Override
	public Authentication attemptAuthentication(HttpServletRequest request, HttpServletResponse response)
			throws AuthenticationException {
		if (postOnly && !request.getMethod().equals("POST")) {
			throw new AuthenticationServiceException("Authentication method not supported: " + request.getMethod());
		}
		String mobile = obtainMobile(request);
		if (mobile == null) {
			mobile = "";
		}
		mobile = mobile.trim();
		SmsCodeAuthenticationToken authRequest = new SmsCodeAuthenticationToken(mobile);
		// 把请求信息设到Token中
		setDetails(request, authRequest);
		return this.getAuthenticationManager().authenticate(authRequest);
	}
	/**
	 * 获取手机号
	 */
	protected String obtainMobile(HttpServletRequest request) {
		return request.getParameter(mobileParameter);
	}
	protected void setDetails(HttpServletRequest request, SmsCodeAuthenticationToken authRequest) {
		authRequest.setDetails(authenticationDetailsSource.buildDetails(request));
	}
	public void setMobileParameter(String usernameParameter) {
		Assert.hasText(usernameParameter, "Username parameter must not be empty or null");
		this.mobileParameter = usernameParameter;
	}
	public void setPostOnly(boolean postOnly) {
		this.postOnly = postOnly;
	}
	public final String getMobileParameter() {
		return mobileParameter;
	}
}

SmsAuthenticationProvider

• 作用：提供认证Token的校验逻辑，配置为能够支持SmsCodeAuthenticationToken的校验
• 实现：实现AuthenticationProvider接口，实现其两个方法。

public class SmsCodeAuthenticationProvider implements AuthenticationProvider {
	private UserDetailsService userDetailsService;
 /**
 * 进行身份认证的逻辑
 *
 * @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;
	}
 /**
 * 表示支持校验的Token，这里是SmsCodeAuthenticationToken
 *
 * @param authentication
 * @return
 */
	@Override
	public boolean supports(Class<?> authentication) {
		return SmsCodeAuthenticationToken.class.isAssignableFrom(authentication);
	}
	public UserDetailsService getUserDetailsService() {
		return userDetailsService;
	}
	public void setUserDetailsService(UserDetailsService userDetailsService) {
		this.userDetailsService = userDetailsService;
	}
}

ValidateCodeFilter

• 作用：校验短信验证码
• 实现：和图形验证码类似，继承OncePerRequestFilter接口防止多次调用，主要就是验证码验证逻辑，验证通过则继续下一个过滤器。

@Component("validateCodeFilter")
public class ValidateCodeFilter extends OncePerRequestFilter implements InitializingBean {
	/**
	 * 验证码校验失败处理器
	 */
	@Autowired
	private AuthenticationFailureHandler authenticationFailureHandler;
	/**
	 * 系统配置信息
	 */
	@Autowired
	private SecurityProperties securityProperties;
	/**
	 * 系统中的校验码处理器
	 */
	@Autowired
	private ValidateCodeProcessorHolder validateCodeProcessorHolder;
	/**
	 * 存放所有需要校验验证码的url
	 */
	private Map<String, ValidateCodeType> urlMap = new HashMap<>();
	/**
	 * 验证请求url与配置的url是否匹配的工具类
	 */
	private AntPathMatcher pathMatcher = new AntPathMatcher();
	/**
	 * 初始化要拦截的url配置信息
	 */
	@Override
	public void afterPropertiesSet() throws ServletException {
		super.afterPropertiesSet();
		urlMap.put("/authentication/mobile", ValidateCodeType.SMS);
		addUrlToMap(securityProperties.getCode().getSms().getUrl(), ValidateCodeType.SMS);
	}
	/**
	 * 讲系统中配置的需要校验验证码的URL根据校验的类型放入map
	 *
	 * @param urlString
	 * @param type
	 */
	protected void addUrlToMap(String urlString, ValidateCodeType type) {
		if (StringUtils.isNotBlank(urlString)) {
			String[] urls = StringUtils.splitByWholeSeparatorPreserveAllTokens(urlString, ",");
			for (String url : urls) {
				urlMap.put(url, type);
			}
		}
	}
	/**
	 * 验证短信验证码
	 *
	 * @param request
	 * @param response
	 * @param chain
	 * @throws ServletException
	 * @throws IOException
	 */
	@Override
	protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain chain)
			throws ServletException, IOException {
		ValidateCodeType type = getValidateCodeType(request);
		if (type != null) {
			logger.info("校验请求(" + request.getRequestURI() + ")中的验证码,验证码类型" + type);
			try {
				// 进行验证码的校验
				validateCodeProcessorHolder.findValidateCodeProcessor(type)
						.validate(new ServletWebRequest(request, response));
				logger.info("验证码校验通过");
			} catch (ValidateCodeException exception) {
				// 如果校验抛出异常，则交给我们之前文章定义的异常处理器进行处理
				authenticationFailureHandler.onAuthenticationFailure(request, response, exception);
				return;
			}
		}
		// 继续调用后边的过滤器
		chain.doFilter(request, response);
	}
	/**
	 * 获取校验码的类型，如果当前请求不需要校验，则返回null
	 *
	 * @param request
	 * @return
	 */
	private ValidateCodeType getValidateCodeType(HttpServletRequest request) {
		ValidateCodeType result = null;
		if (!StringUtils.equalsIgnoreCase(request.getMethod(), "GET")) {
			Set<String> urls = urlMap.keySet();
			for (String url : urls) {
				if (pathMatcher.match(url, request.getRequestURI())) {
					result = urlMap.get(url);
				}
			}
		}
		return result;
	}
}

添加配置

SmsCodeAuthenticationSecurityConfig

作用：配置SmsCodeAuthenticationFilter，后面需要把这些配置加到主配置类BrowserSecurityConfig

@Component
public class SmsCodeAuthenticationSecurityConfig extends SecurityConfigurerAdapter<DefaultSecurityFilterChain, HttpSecurity> {

	@Autowired
	private AuthenticationSuccessHandler meicloudAuthenticationSuccessHandler;

	@Autowired
	private AuthenticationFailureHandler meicloudAuthenticationFailureHandler;

	@Autowired
	private UserDetailsService userDetailsService;

	@Autowired
	private PersistentTokenRepository persistentTokenRepository;

	@Override
	public void configure(HttpSecurity http) throws Exception {

		SmsCodeAuthenticationFilter smsCodeAuthenticationFilter = new SmsCodeAuthenticationFilter();
		// 设置AuthenticationManager
		smsCodeAuthenticationFilter.setAuthenticationManager(http.getSharedObject(AuthenticationManager.class));
		// 设置登录成功处理器
		smsCodeAuthenticationFilter.setAuthenticationSuccessHandler(meicloudAuthenticationSuccessHandler);
		// 设置登录失败处理器
		smsCodeAuthenticationFilter.setAuthenticationFailureHandler(meicloudAuthenticationFailureHandler);
		String key = UUID.randomUUID().toString();
		smsCodeAuthenticationFilter.setRememberMeServices(new PersistentTokenBasedRememberMeServices(key, userDetailsService, persistentTokenRepository));

		SmsCodeAuthenticationProvider smsCodeAuthenticationProvider = new SmsCodeAuthenticationProvider();
		smsCodeAuthenticationProvider.setUserDetailsService(userDetailsService);
		// 将自己写的Provider加到Provider集合里去
		http.authenticationProvider(smsCodeAuthenticationProvider)
			.addFilterAfter(smsCodeAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
	}
}

BrowserSecurityConfig

作用：主配置类；添加短信验证码配置类、添加SmsCodeAuthenticationSecurityConfig配置

@Configuration
public class BrowserSecurityConfig extends WebSecurityConfigurerAdapter {
	@Bean
	public PasswordEncoder passwordEncoder() {
		return new BCryptPasswordEncoder();
	}
	@Autowired
	private SecurityProperties securityProperties;
	@Autowired
	private DataSource dataSource;
	@Autowired
	private UserDetailsService userDetailsService;
	@Autowired
	private AuthenticationSuccessHandler meicloudAuthenticationSuccessHandler;
	@Autowired
	private AuthenticationFailureHandler meicloudAuthenticationFailureHandler;
	@Autowired
	private SmsCodeAuthenticationSecurityConfig smsCodeAuthenticationSecurityConfig;

	@Override
	protected void configure(HttpSecurity http) throws Exception {
		// 验证码校验过滤器
		ValidateCodeFilter validateCodeFilter = new ValidateCodeFilter();
		// 将验证码校验过滤器加到 UsernamePasswordAuthenticationFilter 过滤器之前
		http.addFilterBefore(validateCodeFilter, UsernamePasswordAuthenticationFilter.class)
				.formLogin()
				// 当用户登录认证时默认跳转的页面
				.loginPage("/authentication/require")
				// 以下这行 UsernamePasswordAuthenticationFilter 会知道要处理表单的 /authentication/form 请求，而不是默认的 /login
				.loginProcessingUrl("/authentication/form")
				.successHandler(meicloudAuthenticationSuccessHandler)
				.failureHandler(meicloudAuthenticationFailureHandler)
				// 配置记住我功能
				.and()
				.rememberMe()
				// 配置TokenRepository
				.tokenRepository(persistentTokenRepository())
				// 配置Token过期时间
				.tokenValiditySeconds(3600)
				// 最终拿到用户名之后，使用UserDetailsService去做登录
				.userDetailsService(userDetailsService)
				.and()
				.authorizeRequests()
				// 排除对 "/authentication/require" 和 "/meicloud-signIn.html" 的身份验证
				.antMatchers("/authentication/require", securityProperties.getBrowser().getSignInPage(), "/code/*").permitAll()
				// 表示所有请求都需要身份验证
				.anyRequest()
				.authenticated()
				.and()
				.csrf().disable()// 暂时把跨站请求伪造的功能关闭掉
				// 相当于把smsCodeAuthenticationSecurityConfig里的配置加到上面这些配置的后面
				.apply(smsCodeAuthenticationSecurityConfig);
	}
	/**
	 * 记住我功能的Token存取器配置
	 *
	 * @return
	 */
	@Bean
	public PersistentTokenRepository persistentTokenRepository() {
		JdbcTokenRepositoryImpl tokenRepository = new JdbcTokenRepositoryImpl();
		tokenRepository.setDataSource(dataSource);
		// 启动的时候自动创建表，建表语句 JdbcTokenRepositoryImpl 已经都写好了
		tokenRepository.setCreateTableOnStartup(true);
		return tokenRepository;
	}
}
