1 前端代码
axios.defaults.baseURL ='http://192.168.1.147:8090'
axios.defaults.timeout =6000
axios.interceptors.request.use(
config => {
// config.headers['Content-Type'] = 'application/x-www-form-urlencoded';
let token =localStorage.getItem('token')
if (token) {
config.headers.common['token'] =localStorage.getItem('token');
}
return config
},
err => {
return Promise.reject(err);
}
)
2 登录的时候把Token 写入本地存储
localStorage.setItem('token',this.encryptionDesc)
3 后端请求设置跨域
一 设置拦截规则
package com.real2tech.virtualTeach.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
@Configuration
public class WebAppConfigurerextends WebMvcConfigurationSupport {
// addPathPatterns 用于添加拦截规则
// excludePathPatterns 用户排除拦截
@Bean
public HandlerInterceptor getMyInterceptor(){
return new FilterIPActionInterceptor();
}
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(getMyInterceptor())
.addPathPatterns("/**").
excludePathPatterns("/user/login");
}
}
二 跨域配置设置
package com.real2tech.virtualTeach.config;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
@Component
public class CORSFilterextends OncePerRequestFilter {
static final StringORIGIN ="Origin";
public void doFilterInternal(
HttpServletRequest request,
HttpServletResponse response,
FilterChain filterChain)throws ServletException, IOException {
String origin = request.getHeader(ORIGIN);
response.setHeader("Access-Control-Allow-Origin","*");//* or origin as u prefer
response.setHeader("Access-Control-Allow-Credentials","true");
response.setHeader("Access-Control-Allow-Methods","PUT, POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age","3600");
response.setHeader("Access-Control-Allow-Headers","content-type, token");
if (request.getMethod().equals("OPTIONS")) {
response.setStatus(HttpServletResponse.SC_OK);
}else{
filterChain.doFilter(request, response);
}
}
}
三 拦截器配置
*结合自己业务的加密方式 以及其他要求
package com.real2tech.virtualTeach.config;
import com.real2tech.virtualTeach.entity.ManageUser;
import com.real2tech.virtualTeach.mapper.ManageUserMapper;
import com.real2tech.virtualTeach.utils.TokenUits;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@Component
@Service
public class FilterIPActionInterceptorimplements HandlerInterceptor {
private static Loggerlogger = LoggerFactory.getLogger(HandlerInterceptorAdapter.class);
@Autowired
private ManageUserMappermanageUserMapper;
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler)
throws Exception {
logger.info("request请求地址path[{}] uri[{}]", request.getServletPath(),request.getRequestURI());
String url = request.getRequestURI();
if (url.contains("/user/login")) {
return true;
}
String token = request.getHeader("token");
String userId = TokenUits.JudgementToken(token);
ManageUser manageUser =manageUserMapper.selectById(userId);
if (null != manageUser) {
// QueryWrapper queryWrapper = new QueryWrapper();
// queryWrapper.eq("te_id", manageUser.getUserId());
// List list = userEncryptionMapper.selectList(queryWrapper);
// if (null != list && list.size() > 0) {
if (token.equals(manageUser.getEncryptionDesc())) {
return true;
}else {
throw new Exception("请确认你的权限");
}
// }
}
return false;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView)throws Exception {}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
throws Exception {
}
}
以上只为实现 比较简单 勿喷 亲测可行
