Question

我正在尝试为防火墙创建报告功能。防火墙规则以json格式存储。

以下是字符串示例。

[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]

preg_match_all过滤器我有：

    preg_match_all('/\"description":"(.*?)\","matchers"/',$str,$description);
preg_match_all('/\"id":(.*?)\,"/',$str,$id);
preg_match_all('/\"ruleId":(.*?)\,"/',$str,$rule_id);
preg_match_all('/\"enabled":(.*?)\,"description"/',$str,$enable);
preg_match_all('/\"block":(.*?)\,"/',$str,$block);
preg_match_all('/\"log":(.*?)\}/',$str,$log);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_ADDR"/',$str,$dest_add);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_PORT"/',$str,$dest_port);
preg_match_all('/\"value":"(.*?)\","matcherType":"DST_INTF"/',$str,$dest_int);
preg_match_all('/\"value":"(.*?)\,","matcherType":"SRC_ADDR"/',$str,$src_add);
preg_match_all('/\"value":"(.*?)\","matcherType":"SRC_INTF"/',$str,$src_int);
preg_match_all('/\"value":"(.*?)\","matcherType":"PROTOCOL"/',$str,$protocol);
preg_match_all('/\"value":"(.*?)\","matcherType":"DIRECTORY_CONNECTOR_USERNAME"/',$str,$user);
preg_match_all('/\"value":"(.*?)\","matcherType":"DIRECTORY_CONNECTOR_GROUP"/',$str,$group);

evry matcher的开头是VALUE“：”当我打印$ dest_port时我得到"1.1.1.1","matcherType":"DST_ADDR"}, {“invert”：false，“javaClass”：“com.untangle.node.firewall.FirewallRuleMatcher “，”“值”：“80”而不是80.

任何有preg_match_all的人首先找到matchertype，然后读回“value”的后缀：“？

任何帮助都会很棒！

Answer 1

$xyz = <<<EOX
[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]
EOX;

var_dump(json_decode($xyz)); //execute other operations, iteration etc here

这比正则表达式好多了。返回结构化数据，您可以迭代。

Answer 2

结束使用json_decode。

样品：

$jsondata ='[{"id":1,"enabled":true,"description":"TEMP","matchers":{"javaClass":"java.util.LinkedList","list":[{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1.1.1.1","matcherType":"DST_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"80","matcherType":"DST_PORT"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,3,2","matcherType":"DST_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"2.2.2.2","matcherType":"SRC_ADDR"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"1,2,wan","matcherType":"SRC_INTF"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"UDP,TCP,any","matcherType":"PROTOCOL"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"svrbjgu","matcherType":"DIRECTORY_CONNECTOR_USERNAME"},{"invert":false,"javaClass":"com.untangle.node.firewall.FirewallRuleMatcher","value":"intern-it","matcherType":"DIRECTORY_CONNECTOR_GROUP"}]},"ruleId":5001,"javaClass":"com.untangle.node.firewall.FirewallRule","block":false,"log":true}]';
$data = json_decode($jsondata,true);
echo '<table><tr><th WIDTH="10">Nr.</th><th WIDTH="10">RuleID</th><th WIDTH="150">Description</th><th WIDTH="100">Protocol</th><th WIDTH="75">Src Int</th><th WIDTH="150">Src Address</th><th WIDTH="100">Src Port</th><th WIDTH="75">Dest. Int</th><th WIDTH="150">Dest Address</th><th WIDTH="100">Dest. Port</th><th WIDTH="50">Action</th><th WIDTH="50">Log</th><th WIDTH="50">Enabled</th></tr>';
echo "<tr><td>test.</td><td> {$data[0]['ruleId']} </td><td>{$data[0]['description']}</td><td>{$data[0]['enabled']}</td></tr>" ;

PHP preg_match_all / preg_match
