从Header中获取用户信息

一、描述

用户登录后，后端服务会将用户信息放到heard里

二、代码

@Slf4j
@Component
public class RequestContextComponent {

    /**
     * 获取会员ID
     */
    public Long getMemberId() {
        //从Header中获取用户信息
        try {
            ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            HttpServletRequest request = servletRequestAttributes.getRequest();
            request.setCharacterEncoding("utf-8");
            String uid = request.getHeader("uid");
            if(StringUtil.isNotEmpty(uid)){
                return Long.valueOf(uid);
            }
        } catch (Exception exception) {
            throw new Exception(I18nUtils.message("auth.relogin"));
        }
        return null;
    }

    /**
     * 获取当前登录用户信息
     * @return
     */
    public SecurityUserDTO getSecurity() {
        //从Header中获取用户信息
        try {
            ServletRequestAttributes servletRequestAttributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
            HttpServletRequest request = servletRequestAttributes.getRequest();
            request.setCharacterEncoding("utf-8");
            String user = request.getHeader("user");;
            
            if (user == null) {
                throw new Exception(I18nUtils.message("auth.relogin"));
            }
            JSONObject userJsonObject = new JSONObject(URLDecoder.decode(user, Charset.defaultCharset()) );
            SecurityUserDTO securityDTO = new SecurityUserDTO();
            securityDTO.setId(Convert.toLong(userJsonObject.get("id")));
            securityDTO.setUserName(userJsonObject.getStr("username"));
            securityDTO.setUserType(SecurityUserTypeEnum.valueOf(userJsonObject.getStr("userType")));
            securityDTO.setGrantType(SecurityLoginTypeEnum.parse(userJsonObject.getStr("grantType")));
            if(StringUtil.isNotNullOrEmpty(userJsonObject.get("authorities"))){
                securityDTO.setRoles(Convert.toList(String.class,userJsonObject.get("authorities")));
            }
            return securityDTO;
        } catch (Exception exception) {
            throw new Exception(I18nUtils.message("auth.relogin"));
        }
    }
}
