Bonjour Avahi守护程序TXTRecord [英] Bonjour Avahi daemon TXTRecord

问题描述

我尝试使用txt记录在多个设备之间共享信息.因此，我正在使用bonjour/avahi.服务器端可以很好地用作wireshark证明.信息被添加到txt记录中，并使用MDNS发送出去.问题发生在客户端，守护程序/服务似乎并没有一直在更改信息.它卡住了已经过时的信息，当我尝试再次解决该服务时不会自动更新它.

I try to use txt-records to share information between multiple devices. Therefore I am using bonjour/avahi. The server-side works fine as wireshark proofs. Information is added to the txt-record and sent out using MDNS. The problem occurs on the client side, where the daemon/service does not seem to get the information change all the time. It is stuck with information that is already outdated and does not automatically update it when I try to resolve the service again.

在客户端，我将DNSServiceResolve与回调函数结合使用，在该回调函数中，我调用TXTRecordContainsKey和TXTRecordGetValuePtr以确保数据在使用前可用.所有这些都很好用，除了已经提到的那样，信息并不总是更新.

On the client side I am using DNSServiceResolve in combination with a callback function where I call TXTRecordContainsKey and TXTRecordGetValuePtr to make sure the data is available before use. This all works fine except that, as already mentioned, the information is not always updated.

我是否缺少某些内容，或者是否有其他可用来强制守护程序更新其记录的API函数调用(除了DNSServiceResolve之外)?

Am I missing something, or are there any additional API-function calls that I can use to force the daemon to update its record except DNSServiceResolve?

谢谢.
