可以不可以后端不做跨域的任何處理，全部讓前端來(lái)做，比如Nginx？

可以前端做，但是一般都是后端做，寫(xiě)一個(gè)統(tǒng)一過(guò)濾器也可以
?@Override
? ? public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
? ? ? ? HttpServletResponse response = (HttpServletResponse) res;
? ? ? ? response.setHeader("Access-Control-Allow-Origin", "*");
? ? ? ? response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
? ? ? ? response.setHeader("Access-Control-Max-Age", "3600");
? ? ? ? response.addHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
? ? ? ? chain.doFilter(req, res);
? ? }
可以用 openresty
舉報(bào)
應(yīng)用SpringBoot快速搭建擁有用戶(hù)、商品、交易及秒殺活動(dòng)的電商秒殺應(yīng)用。
