Vue 与 Shiro 实现登录功能

Vue 作为前端框架与 Shiro 作为后端安全框架结合实现登录功能，需要前后端分离协作。以下是具体实现方案：

前端 Vue 实现

安装 axios 用于发送 HTTP 请求：

npm install axios

创建登录组件 Login.vue：

<template>
  <div>
    <input v-model="username" placeholder="用户名"/>
    <input v-model="password" type="password" placeholder="密码"/>
    <button @click="login">登录</button>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      username: '',
      password: ''
    };
  },
  methods: {
    login() {
      axios.post('/api/login', {
        username: this.username,
        password: this.password
      }).then(response => {
        localStorage.setItem('token', response.data.token);
        this.$router.push('/dashboard');
      }).catch(error => {
        console.error('登录失败', error);
      });
    }
  }
};
</script>

后端 Shiro 配置

添加 Shiro 依赖（Maven）：

vue shiro实现登录

<dependency>
  <groupId>org.apache.shiro</groupId>
  <artifactId>shiro-spring</artifactId>
  <version>1.8.0</version>
</dependency>

配置 Shiro 的 Realm：

public class CustomRealm extends AuthorizingRealm {
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
        // 授权逻辑
        return null;
    }

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
        UsernamePasswordToken upToken = (UsernamePasswordToken) token;
        String username = upToken.getUsername();
        String password = new String(upToken.getPassword());

        // 验证用户名密码
        if ("admin".equals(username) && "123456".equals(password)) {
            return new SimpleAuthenticationInfo(username, password, getName());
        }
        throw new AuthenticationException("用户名或密码错误");
    }
}

配置 Shiro 的 Filter 和 SecurityManager：

@Configuration
public class ShiroConfig {
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(DefaultWebSecurityManager securityManager) {
        ShiroFilterFactoryBean factoryBean = new ShiroFilterFactoryBean();
        factoryBean.setSecurityManager(securityManager);

        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/api/login", "anon");
        filterChainDefinitionMap.put("/", "authc");
        factoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        return factoryBean;
    }

    @Bean
    public DefaultWebSecurityManager securityManager(CustomRealm realm) {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(realm);
        return securityManager;
    }
}

创建登录接口：

vue shiro实现登录

@RestController
@RequestMapping("/api")
public class LoginController {
    @PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody LoginRequest request) {
        Subject subject = SecurityUtils.getSubject();
        UsernamePasswordToken token = new UsernamePasswordToken(request.getUsername(), request.getPassword());

        try {
            subject.login(token);
            String sessionId = (String) subject.getSession().getId();
            return ResponseEntity.ok().body(Collections.singletonMap("token", sessionId));
        } catch (AuthenticationException e) {
            return ResponseEntity.status(401).body("认证失败");
        }
    }
}

跨域与 Token 验证

配置跨域支持（Spring Boot）：

@Configuration
public class CorsConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/")
                .allowedOrigins("*")
                .allowedMethods("*")
                .allowedHeaders("*");
    }
}

前端请求携带 Token：

axios.interceptors.request.use(config => {
  const token = localStorage.getItem('token');
  if (token) {
    config.headers.Authorization = `Bearer ${token}`;
  }
  return config;
});
