申请测试微信公众号流程_如何申请免测

//该方法就是接口配置url中请求的方法 public String WechatCallBack() throws IOException{ //验证签名的是get请求 boolean isGet = Objects.equals("GET", getRequest().getMethod().toUpperCase()); if(isGet){ //微信公众号服务器接口配置的签名token String token = "dfgsdfgdfg"; //可写在配置文件中，从配置文件中获取，或存在数据库中 //随机数 String nonce = request.getParameter("nonce"); //签名 String signature =request.getParameter("signature"); //时间戳 String timestamp = request.getParameter("timestamp"); //验证token String[] paramArr = new String[] {token,timestamp,nonce}; Arrays.sort(paramArr); //将验证的值返回给微信服务器 PrintWriter out = response.getWriter(); String echostr = request.getParameter("echostr"); if (WechatMessageUtil.checkSignNature(paramArr,signature)){ LOG.error( "===========请求校验成功========"); out.print(echostr); }else{ LOG.error("===========请求校验失败========"); } return null; } }

WechatMessageUtil工具类
