小程序官方流程图如下,官方地址 : https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html :
本文是对接微信小程序自定义登录的一个完整例子实现 ,技术栈为 : SpringBoot+Shiro+JWT+JPA+Redis。
如果对该例子比较感兴趣或者觉得言语表达比较啰嗦,可查看完整的项目地址 : https://github.com/EalenXie/shiro-jwt-applet
主要实现 : 实现了小程序的自定义登陆,将自定义登陆态token返回给小程序作为登陆凭证。用户的信息保存在数据库中,登陆态token缓存在redis中。
效果如下 :
1 . 首先从我们的小程序端调用wx.login() ,获取临时凭证code :
2 . 模拟使用该code,进行小程序的登陆获取自定义登陆态 token,用postman进行测试 :
3 . 调用我们需要认证的接口,并携带该token进行鉴权,获取到返回信息 :
前方高能,本例代码说明较多, 以下是主要的搭建流程 :
1 . 首先新建maven项目 shiro-jwt-applet ,pom依赖 ,主要是shiro和jwt的依赖,和SpringBoot的一些基础依赖。
<?xml version="1.0" encoding="UTF-8"?>4.0.0 name.ealen shiro-jwt-applet 0.0.1-SNAPSHOT jar shiro-wx-jwt Demo project for Spring Boot org.springframework.boot spring-boot-starter-parent 2.0.6.RELEASE UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-actuator org.springframework.boot spring-boot-starter-data-jpa org.springframework.boot spring-boot-starter-data-redis org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test mysql mysql-connector-java org.apache.shiro shiro-spring 1.4.0 com.auth0 java-jwt 3.4.1 com.alibaba fastjson 1.2.47 org.springframework.boot spring-boot-maven-plugin
2 . 配置你的application.yml ,主要是配置你的小程序appid和secret,还有你的数据库和redis
## 请自行修改下面信息 spring: application: name: shiro-jwt-applet jpa: hibernate: ddl-auto: create # 请自行修改 请自行修改 请自行修改 # datasource本地配置 datasource: url: jdbc:mysql://localhost:3306/yourdatabase username: yourname password: yourpass driver-class-name: com.mysql.jdbc.Driver # redis本地配置 请自行配置 redis: database: 0 host: localhost port: 6379 # 微信小程序配置 appid /appsecret wx: applet: appid: yourappid appsecret: yourappsecret
3 . 定义我们存储的微信小程序登陆的实体信息 WxAccount :
package name.ealen.domain.entity; import org.springframework.format.annotation.DateTimeFormat; import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id; import javax.persistence.Table; import java.util.Date; /** * Created by EalenXie on 2018/11/26 10:26. * 实体 属性描述 这里只是简单示例,你可以自定义相关用户信息 */ @Entity @Table public class WxAccount { @Id @GeneratedValue private Integer id; private String wxOpenid; private String sessionKey; @DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss") private Date lastTime; /** * 省略getter/setter */ }
和一个简单的dao 访问数据库 WxAccountRepository :
package name.ealen.domain.repository; import name.ealen.domain.entity.WxAccount; import org.springframework.data.jpa.repository.JpaRepository; /** * Created by EalenXie on 2018/11/26 10:32. */ public interface WxAccountRepository extends JpaRepository{ /** * 根据OpenId查询用户信息 */ WxAccount findByWxOpenid(String wxOpenId); }
4 . 定义我们应用的服务说明 WxAppletService :
package name.ealen.application; import name.ealen.interfaces.dto.Token; /** * Created by EalenXie on 2018/11/26 10:40. * 微信小程序自定义登陆 服务说明 */ public interface WxAppletService { /** * 微信小程序用户登陆,完整流程可参考下面官方地址,本例中是按此流程开发 * https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html * 1 . 我们的微信小程序端传入code。 * 2 . 调用微信code2session接口获取openid和session_key * 3 . 根据openid和session_key自定义登陆态(Token) * 4 . 返回自定义登陆态(Token)给小程序端。 * 5 . 我们的小程序端调用其他需要认证的api,请在header的Authorization里面携带 token信息 * * @param code 小程序端 调用 wx.login 获取到的code,用于调用 微信code2session接口 * @return Token 返回后端 自定义登陆态 token 基于JWT实现 */ public Token wxUserLogin(String code); }
返回给微信小程序token对象声明 Token :
package name.ealen.interfaces.dto; /** * Created by EalenXie on 2018/11/26 18:49. * DTO 返回值token对象 */ public class Token { private String token; public Token(String token) { this.token = token; } /** * 省略getter/setter */ }
5. 配置需要的基本组件,RestTemplate,Redis:
package name.ealen.infrastructure.config; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.http.client.ClientHttpRequestFactory; import org.springframework.http.client.SimpleClientHttpRequestFactory; import org.springframework.web.client.RestTemplate; /** * Created by EalenXie on 2018-03-23 07:37 * RestTemplate的配置类 */ @Configuration public class RestTemplateConfig { @Bean public RestTemplate restTemplate(ClientHttpRequestFactory factory) { return new RestTemplate(factory); } @Bean public ClientHttpRequestFactory simpleClientHttpRequestFactory() { SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory(); factory.setReadTimeout(1000 * 60); //读取超时时间为单位为60秒 factory.setConnectTimeout(1000 * 10); //连接超时时间设置为10秒 return factory; } }
Redis的配置。本例是Springboot2.0的写法(和1.8的版本写法略有不同):
package name.ealen.infrastructure.config; import org.springframework.cache.CacheManager; import org.springframework.cache.annotation.EnableCaching; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.cache.RedisCacheManager; import org.springframework.data.redis.connection.RedisConnectionFactory; /** * Created by EalenXie on 2018-03-23 07:37 * Redis的配置类 */ @Configuration @EnableCaching public class RedisConfig { @Bean public CacheManager cacheManager(RedisConnectionFactory factory) { return RedisCacheManager.create(factory); } }
6. JWT的核心过滤器配置。继承了Shiro的BasicHttpAuthenticationFilter,并重写了其鉴权的过滤方法 :
package name.ealen.infrastructure.config.jwt; import name.ealen.domain.vo.JwtToken; import org.apache.shiro.web.filter.authc.BasicHttpAuthenticationFilter; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.RequestMethod; import javax.servlet.ServletRequest; import javax.servlet.ServletResponse; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * Created by EalenXie on 2018/11/26 10:26. * JWT核心过滤器配置 * 所有的请求都会先经过Filter,所以我们继承官方的BasicHttpAuthenticationFilter,并且重写鉴权的方法。 * 执行流程 preHandle->isAccessAllowed->isLoginAttempt->executeLogin */ public class JwtFilter extends BasicHttpAuthenticationFilter { /** * 判断用户是否想要进行 需要验证的操作 * 检测header里面是否包含Authorization字段即可 */ @Override protected boolean isLoginAttempt(ServletRequest request, ServletResponse response) { String auth = getAuthzHeader(request); return auth != null && !auth.equals(""); } /** * 此方法调用登陆,验证逻辑 */ @Override protected boolean isAccessAllowed(ServletRequest request, ServletResponse response, Object mappedValue) { if (isLoginAttempt(request, response)) { JwtToken token = new JwtToken(getAuthzHeader(request)); getSubject(request, response).login(token); } return true; } /** * 提供跨域支持 */ @Override protected boolean preHandle(ServletRequest request, ServletResponse response) throws Exception { HttpServletRequest httpServletRequest = (HttpServletRequest) request; HttpServletResponse httpServletResponse = (HttpServletResponse) response; httpServletResponse.setHeader("Access-control-Allow-Origin", httpServletRequest.getHeader("Origin")); httpServletResponse.setHeader("Access-Control-Allow-Methods", "GET,POST,OPTIONS,PUT,DELETE"); httpServletResponse.setHeader("Access-Control-Allow-Headers", httpServletRequest.getHeader("Access-Control-Request-Headers")); // 跨域时会首先发送一个option请求,这里我们给option请求直接返回正常状态 if (httpServletRequest.getMethod().equals(RequestMethod.OPTIONS.name())) { httpServletResponse.setStatus(HttpStatus.OK.value()); return false; } return super.preHandle(request, response); } }
JWT的核心配置(包含Token的加密创建,JWT续期,解密验证) :
package name.ealen.infrastructure.config.jwt; import com.auth0.jwt.JWT; import com.auth0.jwt.JWTVerifier; import com.auth0.jwt.algorithms.Algorithm; import com.auth0.jwt.exceptions.JWTDecodeException; import name.ealen.domain.entity.WxAccount; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.StringRedisTemplate; import org.springframework.stereotype.Component; import java.util.Date; import java.util.UUID; import java.util.concurrent.TimeUnit; /** * Created by EalenXie on 2018/11/22 17:16. */ @Component public class JwtConfig { /** * JWT 自定义密钥 我这里写死的 */ private static final String SECRET_KEY = "5371f568a45e5ab1f442c38e0932aef24447139b"; /** * JWT 过期时间值 这里写死为和小程序时间一致 7200 秒,也就是两个小时 */ private static long expire_time = 7200; @Autowired private StringRedisTemplate redisTemplate; /** * 根据微信用户登陆信息创建 token * 注 : 这里的token会被缓存到redis中,用作为二次验证 * redis里面缓存的时间应该和jwt token的过期时间设置相同 * * @param wxAccount 微信用户信息 * @return 返回 jwt token */ public String createTokenByWxAccount(WxAccount wxAccount) { String jwtId = UUID.randomUUID().toString(); //JWT 随机ID,做为验证的key //1 . 加密算法进行签名得到token Algorithm algorithm = Algorithm.HMAC256(SECRET_KEY); String token = JWT.create() .withClaim("wxOpenId", wxAccount.getWxOpenid()) .withClaim("sessionKey", wxAccount.getSessionKey()) .withClaim("jwt-id", jwtId) .withExpiresAt(new Date(System.currentTimeMillis() + expire_time*1000)) //JWT 配置过期时间的正确姿势 .sign(algorithm); //2 . Redis缓存JWT, 注 : 请和JWT过期时间一致 redisTemplate.opsForValue().set("JWT-SESSION-" + jwtId, token, expire_time, TimeUnit.SECONDS); return token; } /** * 校验token是否正确 * 1 . 根据token解密,解密出jwt-id , 先从redis中查找出redisToken,匹配是否相同 * 2 . 然后再对redisToken进行解密,解密成功则 继续流程 和 进行token续期 * * @param token 密钥 * @return 返回是否校验通过 */ public boolean verifyToken(String token) { try { //1 . 根据token解密,解密出jwt-id , 先从redis中查找出redisToken,匹配是否相同 String redisToken = redisTemplate.opsForValue().get("JWT-SESSION-" + getJwtIdByToken(token)); if (!redisToken.equals(token)) return false; //2 . 得到算法相同的JWTVerifier Algorithm algorithm = Algorithm.HMAC256(SECRET_KEY); JWTVerifier verifier = JWT.require(algorithm) .withClaim("wxOpenId", getWxOpenIdByToken(redisToken)) .withClaim("sessionKey", getSessionKeyByToken(redisToken)) .withClaim("jwt-id", getJwtIdByToken(redisToken)) .acceptExpiresAt(System.currentTimeMillis() + expire_time*1000 ) //JWT 正确的配置续期姿势 .build(); //3 . 验证token verifier.verify(redisToken); //4 . Redis缓存JWT续期 redisTemplate.opsForValue().set("JWT-SESSION-" + getJwtIdByToken(token), redisToken, expire_time, TimeUnit.SECONDS); return true; } catch (Exception e) { //捕捉到任何异常都视为校验失败 return false; } } /** * 根据Token获取wxOpenId(注意坑点 : 就算token不正确,也有可能解密出wxOpenId,同下) */ public String getWxOpenIdByToken(String token) throws JWTDecodeException { return JWT.decode(token).getClaim("wxOpenId").asString(); } /** * 根据Token获取sessionKey */ public String getSessionKeyByToken(String token) throws JWTDecodeException { return JWT.decode(token).getClaim("sessionKey").asString(); } /** * 根据Token 获取jwt-id */ private String getJwtIdByToken(String token) throws JWTDecodeException { return JWT.decode(token).getClaim("jwt-id").asString(); } }
7 . 自定义Shiro的Realm配置,Realm是自定义登陆及授权的逻辑配置 :
package name.ealen.infrastructure.config.shiro; import name.ealen.domain.vo.JwtToken; import name.ealen.infrastructure.config.jwt.JwtConfig; import org.apache.shiro.authc.AuthenticationException; import org.apache.shiro.authc.AuthenticationInfo; import org.apache.shiro.authc.AuthenticationToken; import org.apache.shiro.authc.SimpleAuthenticationInfo; import org.apache.shiro.authc.credential.CredentialsMatcher; import org.apache.shiro.authz.AuthorizationInfo; import org.apache.shiro.authz.SimpleAuthorizationInfo; import org.apache.shiro.realm.AuthorizingRealm; import org.apache.shiro.realm.Realm; import org.apache.shiro.subject.PrincipalCollection; import org.springframework.stereotype.Component; import javax.annotation.Resource; import java.util.Collections; import java.util.LinkedList; import java.util.List; /** * Created by EalenXie on 2018/11/26 12:12. * Realm 的一个配置管理类 allRealm()方法得到所有的realm */ @Component public class ShiroRealmConfig { @Resource private JwtConfig jwtConfig; /** * 配置所有自定义的realm,方便起见,应对可能有多个realm的情况 */ public ListallRealm() { List realmList = new LinkedList<>(); AuthorizingRealm jwtRealm = jwtRealm(); realmList.add(jwtRealm); return Collections.unmodifiableList(realmList); } /** * 自定义 JWT的 Realm * 重写 Realm 的 supports() 方法是通过 JWT 进行登录判断的关键 */ private AuthorizingRealm jwtRealm() { AuthorizingRealm jwtRealm = new AuthorizingRealm() { /** * 注意坑点 : 必须重写此方法,不然Shiro会报错 * 因为创建了 JWTToken 用于替换Shiro原生 token,所以必须在此方法中显式的进行替换,否则在进行判断时会一直失败 */ @Override public boolean supports(AuthenticationToken token) { return token instanceof JwtToken; } @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) { return new SimpleAuthorizationInfo(); } /** * 校验 验证token逻辑 */ @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) { String jwtToken = (String) token.getCredentials(); String wxOpenId = jwtConfig.getWxOpenIdByToken(jwtToken); String sessionKey = jwtConfig.getSessionKeyByToken(jwtToken); if (wxOpenId == null || wxOpenId.equals("")) throw new AuthenticationException("user account not exits , please check your token"); if (sessionKey == null || sessionKey.equals("")) throw new AuthenticationException("sessionKey is invalid , please check your token"); if (!jwtConfig.verifyToken(jwtToken)) throw new AuthenticationException("token is invalid , please check your token"); return new SimpleAuthenticationInfo(token, token, getName()); } }; jwtRealm.setCredentialsMatcher(credentialsMatcher()); return jwtRealm; } /** * 注意坑点 : 密码校验 , 这里因为是JWT形式,就无需密码校验和加密,直接让其返回为true(如果不设置的话,该值默认为false,即始终验证不通过) */ private CredentialsMatcher credentialsMatcher() { return (token, info) -> true; } }
Shiro的核心配置,包含配置Realm :
package name.ealen.infrastructure.config.shiro; import name.ealen.infrastructure.config.jwt.JwtFilter; import org.apache.shiro.mgt.DefaultSessionStorageEvaluator; import org.apache.shiro.mgt.DefaultSubjectDAO; import org.apache.shiro.spring.LifecycleBeanPostProcessor; import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor; import org.apache.shiro.spring.web.ShiroFilterFactoryBean; import org.apache.shiro.web.mgt.DefaultWebSecurityManager; import org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.DependsOn; import javax.servlet.Filter; import java.util.HashMap; import java.util.Map; /** * Created by EalenXie on 2018/11/22 18:28. */ @Configuration public class ShirConfig { /** * SecurityManager,安全管理器,所有与安全相关的操作都会与之进行交互; * 它管理着所有Subject,所有Subject都绑定到SecurityManager,与Subject的所有交互都会委托给SecurityManager * DefaultWebSecurityManager : * 会创建默认的DefaultSubjectDAO(它又会默认创建DefaultSessionStorageEvaluator) * 会默认创建DefaultWebSubjectFactory * 会默认创建ModularRealmAuthenticator */ @Bean public DefaultWebSecurityManager securityManager(ShiroRealmConfig shiroRealmConfig) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); securityManager.setRealms(shiroRealmConfig.allRealm()); //设置realm DefaultSubjectDAO subjectDAO = (DefaultSubjectDAO) securityManager.getSubjectDAO(); // 关闭自带session DefaultSessionStorageEvaluator evaluator = (DefaultSessionStorageEvaluator) subjectDAO.getSessionStorageEvaluator(); evaluator.setSessionStorageEnabled(Boolean.FALSE); subjectDAO.setSessionStorageEvaluator(evaluator); return securityManager; } /** * 配置Shiro的访问策略 */ @Bean public ShiroFilterFactoryBean factory(DefaultWebSecurityManager securityManager) { ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean(); MapfilterMap = new HashMap<>(); filterMap.put("jwt", new JwtFilter()); factoryBean.setFilters(filterMap); factoryBean.setSecurityManager(securityManager); Map filterRuleMap = new HashMap<>(); //登陆相关api不需要被过滤器拦截 filterRuleMap.put("/api/wx/user/login/**", "anon"); filterRuleMap.put("/api/response/**", "anon"); // 所有请求通过JWT Filter filterRuleMap.put("/**", "jwt"); factoryBean.setFilterChainDefinitionMap(filterRuleMap); return factoryBean; } /** * 添加注解支持 */ @Bean @DependsOn("lifecycleBeanPostProcessor") public DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator() { DefaultAdvisorAutoProxyCreator defaultAdvisorAutoProxyCreator = new DefaultAdvisorAutoProxyCreator(); defaultAdvisorAutoProxyCreator.setProxyTargetClass(true); // 强制使用cglib,防止重复代理和可能引起代理出错的问题 return defaultAdvisorAutoProxyCreator; } /** * 添加注解依赖 */ @Bean public LifecycleBeanPostProcessor lifecycleBeanPostProcessor() { return new LifecycleBeanPostProcessor(); } /** * 开启注解验证 */ @Bean public AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor(DefaultWebSecurityManager securityManager) { AuthorizationAttributeSourceAdvisor authorizationAttributeSourceAdvisor = new AuthorizationAttributeSourceAdvisor(); authorizationAttributeSourceAdvisor.setSecurityManager(securityManager); return authorizationAttributeSourceAdvisor; } }
用于Shiro鉴权的JwtToken对象 :
package name.ealen.domain.vo; import org.apache.shiro.authc.AuthenticationToken; /** * Created by EalenXie on 2018/11/22 18:21. * 鉴权用的token vo ,实现 AuthenticationToken */ public class JwtToken implements AuthenticationToken { private String token; public JwtToken(String token) { this.token = token; } @Override public Object getPrincipal() { return token; } @Override public Object getCredentials() { return token; } public String getToken() { return token; } public void setToken(String token) { this.token = token; } }
8 . 实现实体的行为及业务逻辑,此例主要是调用微信接口code2session和创建返回token :
package name.ealen.domain.service; import name.ealen.application.WxAppletService; import name.ealen.domain.entity.WxAccount; import name.ealen.domain.repository.WxAccountRepository; import name.ealen.domain.vo.Code2SessionResponse; import name.ealen.infrastructure.config.jwt.JwtConfig; import name.ealen.infrastructure.util.HttpUtil; import name.ealen.infrastructure.util.JSONUtil; import name.ealen.interfaces.dto.Token; import org.apache.shiro.authc.AuthenticationException; import org.springframework.beans.factory.annotation.Value; import org.springframework.http.HttpEntity; import org.springframework.http.HttpHeaders; import org.springframework.http.HttpMethod; import org.springframework.stereotype.Service; import org.springframework.util.LinkedMultiValueMap; import org.springframework.util.MultiValueMap; import org.springframework.web.client.RestTemplate; import javax.annotation.Resource; import java.net.URI; import java.util.Date; /** * Created by EalenXie on 2018/11/26 10:50. * 实体 行为描述 */ @Service public class WxAccountService implements WxAppletService { @Resource private RestTemplate restTemplate; @Value("${wx.applet.appid}") private String appid; @Value("${wx.applet.appsecret}") private String appSecret; @Resource private WxAccountRepository wxAccountRepository; @Resource private JwtConfig jwtConfig; /** * 微信的 code2session 接口 获取微信用户信息 * 官方说明 : https://developers.weixin.qq.com/miniprogram/dev/api/open-api/login/code2Session.html */ private String code2Session(String jsCode) { String code2SessionUrl = "https://api.weixin.qq.com/sns/jscode2session"; MultiValueMapparams = new LinkedMultiValueMap<>(); params.add("appid", appid); params.add("secret", appSecret); params.add("js_code", jsCode); params.add("grant_type", "authorization_code"); URI code2Session = HttpUtil.getURIwithParams(code2SessionUrl, params); return restTemplate.exchange(code2Session, HttpMethod.GET, new HttpEntity (new HttpHeaders()), String.class).getBody(); } /** * 微信小程序用户登陆,完整流程可参考下面官方地址,本例中是按此流程开发 * https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html * * @param code 小程序端 调用 wx.login 获取到的code,用于调用 微信code2session接口 * @return 返回后端 自定义登陆态 token 基于JWT实现 */ @Override public Token wxUserLogin(String code) { //1 . code2session返回JSON数据 String resultJson = code2Session(code); //2 . 解析数据 Code2SessionResponse response = JSONUtil.jsonString2Object(resultJson, Code2SessionResponse.class); if (!response.getErrcode().equals("0")) throw new AuthenticationException("code2session失败 : " + response.getErrmsg()); else { //3 . 先从本地数据库中查找用户是否存在 WxAccount wxAccount = wxAccountRepository.findByWxOpenid(response.getOpenid()); if (wxAccount == null) { wxAccount = new WxAccount(); wxAccount.setWxOpenid(response.getOpenid()); //不存在就新建用户 } //4 . 更新sessionKey和 登陆时间 wxAccount.setSessionKey(response.getSession_key()); wxAccount.setLastTime(new Date()); wxAccountRepository.save(wxAccount); //5 . JWT 返回自定义登陆态 Token String token = jwtConfig.createTokenByWxAccount(wxAccount); return new Token(token); } } }
小程序code2session接口的返回VO对象Code2SessionResponse :
package name.ealen.domain.vo; /** * 微信小程序 Code2Session 接口返回值 对象 * 具体可以参考小程序官方API说明 : https://developers.weixin.qq.com/miniprogram/dev/api/open-api/login/code2Session.html */ public class Code2SessionResponse { private String openid; private String session_key; private String unionid; private String errcode = "0"; private String errmsg; private int expires_in; /** * 省略getter/setter */ }
9. 定义我们的接口信息WxAppletController,此例包含一个登录获取token的api和一个需要认证的测试api :
package name.ealen.interfaces.facade; import name.ealen.application.WxAppletService; import org.apache.shiro.authz.annotation.RequiresAuthentication; import org.springframework.http.HttpStatus; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.HashMap; import java.util.Map; /** * Created by EalenXie on 2018/11/26 10:44. * 小程序后台 某 API */ @RestController public class WxAppletController { @Resource private WxAppletService wxAppletService; /** * 微信小程序端用户登陆api * 返回给小程序端 自定义登陆态 token */ @PostMapping("/api/wx/user/login") public ResponseEntity wxAppletLoginApi(@RequestBody Maprequest) { if (!request.containsKey("code") || request.get("code") == null || request.get("code").equals("")) { Map result = new HashMap<>(); result.put("msg", "缺少参数code或code不合法"); return new ResponseEntity<>(result, HttpStatus.BAD_REQUEST); } else { return new ResponseEntity<>(wxAppletService.wxUserLogin(request.get("code")), HttpStatus.OK); } } /** * 需要认证的测试接口 需要 @RequiresAuthentication 注解,则调用此接口需要 header 中携带自定义登陆态 authorization */ @RequiresAuthentication @PostMapping("/sayHello") public ResponseEntity sayHello() { Map result = new HashMap<>(); result.put("words", "hello World"); return new ResponseEntity<>(result, HttpStatus.OK); } }
10 . 运行主类,检查与数据库和redis的连接,进行测试 :
package name.ealen; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * Created by EalenXie on 2018/11/26 10:25. */ @SpringBootApplication public class ShiroJwtAppletApplication { public static void main(String[] args) { SpringApplication.run(ShiroJwtAppletApplication.class, args); }
