Question

我需要解析avahi浏览结果以获取PHP中的某些信息。我并不是基于“可解析的” Avahi浏览器（-p），因为这似乎比不可解析的解析更难解析，除非我弄错了。

由于我可以将浏览限制为某些类型，因此我认为只需要从字符串中绘制IP：port和设备名称。首选IPV4。该示例没有IPV6，但是进行了一些搜索，但是我认为总会有IPV4，对吗？仅使用IPV4可能是安全的。

+ wlp61s0 IPv4 Canon MG5700 series                           _uscan._tcp          local

= wlp61s0 IPv6 Canon MG5700 series                           _uscan._tcp          local
hostname = [ED122D000000.local]
address = [192.168.0.252]
port = [80]
txt = ["duplex=F" "is=platen" "cs=grayscale,color" "rs=eSCL" "representation=http://ED122D000000.local./icon/printer_icon.png" "vers=2.5" "UUID=00000000-0000-1000-8000-00BBC1ED122D" "adminurl=http://ED122D000000.local./index.html?page=PAGE_AAP" "note=Rich's office" "pdl=image/jpeg,application/pdf" "ty=Canon MG5700 series" "txtvers=1"]

编辑-------------------------------- @Martn Zetler是的，它适用于最初发布的字符串，但不适用于此字符串。同样，正如另一位发帖人所述，顺序的确发生了变化，因此使用不带描述符的可解析格式将是不可靠的。

类似的正则表达式模式应该可以用作Cookie切割器：

$subject = ...                           
$pattern = '^=\s\w+\sIPv4\s(.*)\s+_uscan\._tcp\s+\w+\nhostname\s=\s\[(.*)\]\naddress\s=\s\[(.*)\]\nport\s=\s\[(.*)\]\ntxt\s=\s\[(.*)\]\n$';
if (preg_match($pattern, $subject, $matches)) {
    die('<pre>'.print_r($matches, true).'</pre>');
}

在/etc/avahi/avahi-daemon.conf中，您可以使用use-ipv6=no禁用IPv6。
