Request 网络操作扩展


Request扩展,可以实现如携带cookie、伪造来路、伪造浏览器等任意复杂的网络请求

安装:

composer require jaeger/querylist-ext-request

GIT地址:

https://github.com/jae-jae/QueryList-Ext-Request.git

依赖(通过Composer安装的请忽略)

Request扩展依赖Http类,Git地址为:https://github.com/jae-jae/Http.git

手动安装插件教程:http://doc.querylist.cc/site/index/doc/7

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。

//HTTP操作扩展
$urls = QueryList::run('Request',[
        'target' => 'http://cms.querylist.cc/news/list_2.html',
        'referrer'=>'http://cms.querylist.cc',
        'method' => 'GET',
        'params' => ['var1' => 'testvalue', 'var2' => 'somevalue'],
        'user_agent'=>'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0',
        'cookiePath' => './cookie.txt',
        'timeout' =>'30'
    ])->setQuery(['link' => ['h2>a','href','',function($content){
    //利用回调函数补全相对链接
    $baseUrl = 'http://cms.querylist.cc';
    return $baseUrl.$content;
}]],'.cate_list li')->getData(function($item){
    return $item['link'];
});
