    private static final String WX_AGENT = "micromessenger";
    private static final String ALI_AGENT = "alipay";


    public String getBrowser(HttpServletRequest request) {
        String agent = request.getHeader("User-Agent").toLowerCase();
        if(agent!=null) {
            if (agent.toLowerCase().contains(WX_AGENT)) {
                return "来自微信";
            } else if (agent.toLowerCase().contains(ALI_AGENT)) {
                return "来自支付宝";
            }
        }
        return "来自未知星球";
