写在开头
1.由于业务需要，需要进行半自动化的游戏资讯采集。１７１７３是国内对标游戏资讯相对丰富与更新比较勤的网站，因此也成了采集目标之一。
2.QueryList是一款开源的渐进式PHP采集框架,上手容易（从入门到采集到数据用了大约半小时，不含后期数据清洗）。
使用框架：Lumen+QueryList
安装QueryList Composer包
composer require jaeger/querylist
routes路由添加
$router->get('/gather','Headline\GatherController@get_content');
传参
pageCount(页数)
type(类型)
handle(中转，'17173')
如:/gather?pageCount=1&type=1&handle=17173
返回结果
{
msg:采集成功
code:200
count:20
}
Controller代码

public function get_content(REQUEST $request)
{
$pageCount = $request->post('p
// ageCount'); //获取多少页内容
$type = $request->post('type'); //
$handle = $request->post('handle');
$pageCount = empty($pageCount) ? 1 : $pageCount;
$service = new RulesService();
try{
switch ($handle){
case '17173':
$result = $service->rules($pageCount,$type);
