静态方法，访问入口
| public static Query ( string $page, array $rules, string $range = '', $outputEncoding = null, string $inputEncoding = null, boolean | false $removeHead = false ) : mixed | ||
| $page | string | 要抓取的网页URL地址(支持https);或者是html源代码 |
| $rules | array | 【选择器数组】说明：格式array("名称"=>array("选择器","类型"[,"标签过滤列表"][,"回调函数"]),.......[,"callback"=>"全局回调函数"]); 【选择器】说明:可以为任意的jQuery选择器语法 【类型】说明：值 "text" ,"html" ,"HTML标签属性" , 【标签过滤列表】:可选，要过滤的选择器名，多个用空格隔开,当标签名前面添加减号(-)时（此时标签可以为任意的元素选择器），表示移除该标签以及标签内容，否则当【类型】值为text时表示需要保留的HTML标签，为html时表示要过滤掉的HTML标签 【回调函数】/【全局回调函数】：可选，字符串（函数名） 或 数组（array("类名","类的静态方法")），回调函数应有俩个参数，第一个参数是选择到的内容，第二个参数是选择器数组下标，回调函数会覆盖全局回调函数 |
| $range | string | 【块选择器】：指 先按照规则 选出 几个大块 ，然后再分别再在块里面 进行相关的选择 |
| $inputEncoding | string | 【输入编码格式】明确指定输入的页面编码格式(UTF-8,GB2312,.....)，防止出现乱码,如果设置为 假值 则自动识别 |
| $removeHead | boolean | false | 【是否移除页面头部区域】 乱码终极解决方案 |
| 리턴 | mixed | |
