问题描述：我使用EMQX的Exhook来进行授权操作，但是无论结果是deny还是allow，日志中都会出现 “authorization_module_nomatch”。
请问：
1.出现authorization_module_nomatch，是不是说明授权链上前面的授权规则（ACL、MSQL等）均无法断定最终结果，所以会交由Exhook的onClientAuthorize来决定？
2.该日志对业务有什么影响吗？
3.能否去除该日志？

@Override
public void onClientAuthorize(ClientAuthorizeRequest request, StreamObserver<ValuedResponse> responseObserver) {
boolean result = true;
String clientId = request.getClientinfo().getClientid();
String topic = request.getTopic();
ClientAuthorizeRequest.AuthorizeReqType reqType = request.getType();
if (ClientAuthorizeRequest.AuthorizeReqType.SUBSCRIBE.equals(request.getType())) {
if ("GW".equals(topic) || "MS".equals(topic)) {
result = false;
} else if (!clientId.startsWith(ClientService.ICLOUD_ACCOUNT_PREFIX) && (topic.contains("#") || topic.contains("+") || topic.contains("$"))) {
result = false;
}
} else if (ClientAuthorizeRequest.AuthorizeReqType.PUBLISH.equals(request.getType())) {
if (topic.length() > 64) {
result = false;
logger.error("Topic too long, clientId: {}, topic: {}", clientId, topic);
}
if (!clientId.startsWith(ClientService.ICLOUD_ACCOUNT_PREFIX) && !clientId.startsWith(ClientService.DEBUG_ACCOUNT_PREFIX)) {
if (!"GW".equals(topic) && !"MS".equals(topic) && !("$SYS/" + clientId + "/MS").equals(topic) && !("$SYS/" + clientId + "/GW").equals(topic) && !topic.startsWith(ClientService.DEBUG_ACCOUNT_PREFIX)) {
result = false;
}
}
}
ValuedResponse reply = ValuedResponse.newBuilder()
.setBoolResult(result)
.setType(ValuedResponse.ResponsedType.STOP_AND_RETURN)
.build();
logger.error("<<< ExHook: onClientAuthorize FINISHED! ClientId={}, Type={}, Topic={}, FinalResult={}", clientId, reqType, topic, result);
responseObserver.onNext(reply);
responseObserver.onCompleted();
}
