udp廣播設備(支持onvif協議)發現
前言：最近想自己用udp發送組播訊息搜索局域網下的網路設備，發現海康的SADP Tool 和 Onvif Tool 不通，互相抓不到攝像頭，便通過winshark抓包看了下，如下：
<?xml version="1.0" encoding="UTF-8"?>

很容易獲得設備ip和service地址，
海康設備搜索協議：
組播地址：239.255.255.250：37020
組播內容：
<?xml version="1.0" encoding="UTF-8"?>
<Probe>
<Uuid>15213211-C74B-4AEC-934E-DAF526FFC12C</Uuid>
<Types>inquiry</Types>
</Probe>
onvif協議：
組播地址：239.255.255:250:3702
組播內容：
<?xml version="1.0" encoding="utf-8"?>

備注：如果海康的IPC或其他網路設備想要使用onvif協議，需要開啟，如下：
