在视频号管理后台配置的服务器地址是个get请求，为了验证数据的，我参考的是https://developers.weixin.qq.com/doc/channels/API/basics/message_push.html 这篇文档，这个接口要通的话返回的是入参中的echostr，将这个接口配置在图中“服务器地址”处是能成功的。但是回调接口的文档是https://developers.weixin.qq.com/doc/channels/API/order/callback/channels_ec_order_cancel.html，无论是参数还是响应都和上述文档不一样，而且无法将这个回调逻辑的地址配置在“服务器地址”处。那么我的业务逻辑该写在哪个接口呢？

@GetMapping("/wechatChannel/callback/validation")
public Long wechatChannelOrderCallbackValidation(@RequestParam String signature,
                                                   @RequestParam String timestamp,
                                                   @RequestParam String nonce,
                                                   @RequestParam String echostr
                                                   ) {
    String[] strings = {WECHAT_CHANNEL_ORDER_CALLBACK_TOKEN, timestamp, nonce};
    // 使用Arrays.sort方法和Comparator进行字典排序
    Arrays.sort(strings);
    log.info("字典排序后的参数{}", JSON.toJSONString(strings));
    String sign = SignUtils.callbackSign(Lists.newArrayList(strings));
    log.info("视频号回调签名:{},{},{}", sign, signature, sign.equals(signature));
    if(sign.equals(signature)){
        return Long.valueOf(echostr);
    }
    return 0L;
}

@PostMapping("/wechatChannel/paySuccess/callback")
public String wechatChannelOrderPaySuccessCallback(@RequestParam String signature,
                                                   @RequestParam String timestamp,
                                                   @RequestParam String nonce,
                                                   @RequestParam(required = false) String openid,
                                                   @RequestParam(required = false, defaultValue = "aes") String encrypt_type,
                                                   @RequestParam String msg_signature,
                                                   @RequestBody WechatChannelOrderPaySuccessCallbackRequest request) throws AesException {

    log.info("收到视频号消息推送，参数：{},appId：{}, {}, {}", JSON.toJSONString(request), request.getToUserName(), appId, request.getToUserName().equals(appId));

    WXBizJsonMsgCrypt wxcpt = new WXBizJsonMsgCrypt(WECHAT_CHANNEL_ORDER_CALLBACK_TOKEN, WECHAT_CHANNEL_ORDER_CALLBACK_ENCODING_AES_KEY, appId);

    WechatChannelOrderPaySuccessCallbackData data = null;
    try {
        String sMsg = wxcpt.DecryptMsg(msg_signature, timestamp, nonce, JSON.toJSONString(request));
        log.info("视频号订单回调，解密出的参数为：{}", sMsg);
        JSONObject jsonObject = JSON.parseObject(sMsg, JSONObject.class);
        String debugStr = jsonObject.getString("debug_str");
        data = JSON.parseObject(debugStr, WechatChannelOrderPaySuccessCallbackData.class);
    } catch (Exception e) {
        log.error("视频号订单支付完成回调解析参数失败，参数：{}", JSON.toJSONString(request), e);
        return Constants.FAIL;
    }
    try{
        if(data != null){
            if(WechatChannelEventTypeEnum.PAY_SUCCESS.getEvent().equals(data.getEvent())){
                wechatChannelService.orderPaySuccessCallback(data);
            }
        }
    } catch(Exception e){
        log.error("视频号订单支付完成回调失败", e);
    }
    return "success";

}

上面一个接口可以配置在店铺里面，但是仅仅是做了验签；下面一个接口有业务逻辑，但是没法配置在店铺管理里面。
