用法一
$ql = QueryList::run('Request',[ 'http' => [ 'target' => '采集的目标页面', 'referrer' => '来源地址', 'method' => '请求方式,GET、POST等', 'params' => ['提交的参数'=>'参数值','key'=>'value'], //等等其它http相关参数,具体可查看Http类源码 ], 'callback' => function($html,$args){ //处理html的回调方法 return $html; }, 'args' => '传给回调函数的参数' ]); $data = $ql->setQuery(...)->data;用法二
$ql = QueryList::run('Request',[ 'target' => '采集的目标页面', 'referrer' => '来源地址', 'method' => '请求方式,GET、POST等', 'params' => ['提交的参数'=>'参数值','key'=>'value'], //等等其它http相关参数,具体可查看Http类源码 ]); $data = $ql->setQuery(...)->data;
返回值为设置好了html属性的QueryList对象,然后应该调用QueryList的setQuery方法设置采集规则。🎜
