项目大致情况:后端采用RESTful Api,spring boot+spring security+JWT,前端vue全家桶。
部署情况:前端放在nginx里,开了个8088端口,后端jar包运行在8080端口
关于跨域问题解决的七七八八了,但是唯独这个filter的跨域问题解决不了。在spring security的filter中通过response返回信息前端是接收不到的,chrome浏览器也不会显示请求的任何返回,我查了好久才反映过来可能是跨域问题。
需求就是当token失效时,请求接口会通过filter,如果filter判断出token失效,则直接通过response返回一个约定的状态码。如果在这里不返回,服务器直接报500,前端不方便捕捉处理。filter里,请求头可以通过Access-Control-Expose-Headers写进去,前端也能捕获到,请求体怎么办呢?求大神赐教。
目前这样处理是得不到请求体的,其中一个filter的代码:
@Override
protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
String authHeader = httpServletRequest.getHeader("Authorization");
if (authHeader != null && authHeader.startsWith("Bearer ")) {
final String authToken = authHeader.substring("Bearer ".length());
try {
String newToken = JwtUtil.refreshToken(authToken);
if (newToken != null) {
httpServletResponse.setHeader("authentication", newToken);
}
} catch (JwtException e) {
log.error(e.toString());
httpServletResponse.getWriter().write(JSON.toJSONString(Result.failure("无效的token,请重新登陆后操作")));
return;
}
String username;
try {
username = JwtUtil.parseToken(authToken);
} catch (JwtException e) {
log.error(e.toString());
httpServletResponse.getWriter().write(JSON.toJSONString(Result.failure("无效的token,请重新登陆后操作")));
return;
}
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
UserDetails userDetails = sysUserDetailsService.loadUserByUsername(username);
if (userDetails != null) {
UsernamePasswordAuthenticationToken authentication = new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
authentication.setDetails(new WebAuthenticationDetailsSource().buildDetails(httpServletRequest));
SecurityContextHolder.getContext().setAuthentication(authentication);
}
}
}
filterChain.doFilter(httpServletRequest,httpServletResponse);
