Java---微信公众号发送消息_xml

（2019/12/9：有点对不起，完全没写清楚就拿出来了祸害大家，抱歉！！现在说被遗忘的正事：以上信息填写完，服务器搞好大概就是可以通过服务器调用wechat，就可以点击提交了，url是http://ip地址/controller/wechat，Token就随便就好）

@RequestMapping(value = "/wechat",method = RequestMethod.GET,produces = {"application/xml; charset=UTF-8"})
  public void tokenVarify( HttpServletRequest request, HttpServletResponse response) {
    boolean isGet = request.getMethod().toLowerCase().equals("get");
    PrintWriter print;
    if (isGet) {
      // 微信加密签名
      String signature = request.getParameter("signature");
      // 时间戳
      String timestamp = request.getParameter("timestamp");
      // 随机数
      String nonce = request.getParameter("nonce");
      // 随机字符串
      String echostr = request.getParameter("echostr");
      // 通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败
      if (signature != null && CheckUtil.checkSignature(signature, timestamp, nonce)) {
        try {
          print = response.getWriter();
          print.write(echostr);
          print.flush();
        } catch (IOException e) {
          e.printStackTrace();
        }
      }
    }
  }
