测试公众平台配置及调用效果如下： [图片] 后台代码如下： @GetMapping("/handleWxCheckSignature") public String handleWxCheckSignature ( HttpServletRequest request) throws Exception { log.info("===========>checkSign"); //获取微信请求参数 String signature = request.getParameter ("signature"); String timestamp = request.getParameter ("timestamp"); String nonce = request.getParameter ("nonce"); String echostr = request.getParameter ("echostr"); log.info("开始校验此次消息是否来自微信服务器，param->signature:{},\ntimestamp:{},\nnonce:{},\nechostr:{}", signature, timestamp, nonce, echostr); boolean checkFlag = this.checkSignature(signature, timestamp, nonce); log.info("校验是否成功结果:{}",checkFlag); if (checkFlag) { return echostr; } return ""; } 加解密代码如下： public static boolean checkSignature(String signature, String timestamp, String nonce) { String[] arr = {"qweasdzxc", timestamp, nonce}; Arrays.sort(arr); StringBuilder stringBuilder = new StringBuilder(); for (String param : arr) { stringBuilder.append(param); } String hexString = SHA1(stringBuilder.toString()); return signature.equals(hexString); } private static String SHA1(String str) { MessageDigest md; try { md = MessageDigest.getInstance("SHA-1"); byte[] digest = md.digest(str.getBytes()); return toHexString(digest); } catch (NoSuchAlgorithmException e) { log.info("校验令牌Token出现错误：{}", e.getMessage()); } return ""; } /** * 字节数组转化为十六进制 * * @param digest 字节数组 * @return String */ private static String toHexString(byte[] digest) { StringBuilder hexString = new StringBuilder(); for (byte b : digest) { String shaHex = Integer.toHexString(b & 0xff); if (shaHex.length() < 2) { hexString.append(0); } hexString.append(shaHex); } return hexString.toString(); } 解密后返回值为true，已经按照文档要求返回echostr 参数内容，依旧提示配合失败，请问是什么原因 [图片]

原文是“当普通微信用户向公众账号发消息时，微信服务器将POST消息的XML数据包到开发者填写的URL上。”，应该是发到，少了一个发字

这个问题已经3个月了，还是老样子，还有在跟进吗？https://developers.weixin.qq.com/community/develop/doc/0004e8b49c0ce89e19f0dde5360800追问进度也不理 [图片]
