[转载]微信文章和公众号排名查询工具 – 勇哥实验室.

 

概述

闲来无事,研究了下搜狗的微信搜索,顺手写了两个工具:查询文章的关键词排名和公众号的关键词排名。用到的知识很简单:分析搜狗微信搜索参数和正则匹配。点击下面链接可直接访问工具:
微信文章排名查询
微信公众号排名查询

实现思路

1.分析搜狗微信搜索的主要参数,说明如下:
query:查询的关键词
type:查询类型:1-查询公众号;2-查询文章
p:当前页码
num:查询每页的结果数,默认为10
_ast:当前请求的时间
2.为保障查询参数的正确,我首先模拟登陆首页,获得其它意义不明确的参数,和自定义的查询参数还有相关cookies数据一起,作为一个完整请求发送。
3.用正则表达式匹配排名数据即可。
为保证能检索到排名,需要确认一个文章的识别码(公众号识别码就是微信号),具体如下:
识别码

/**
* @params $keyword 关键词
* @params $id 身份标识
* @params $type 搜索类型,1:公众号;2:搜索文章
* @return int 0-无排名;非零值表示当前排名
*/
function getRank($keyword, $id, $type=2)
{
//模擬從首頁登陸
$client = new HttpClient('weixin.sogou.com');
if(!$client->get('/'))
{
die('查询发生错误');
}

$param = array(
'query'=>$keywords,
'type'=>$type,
'p'=>1,
'num'=>100,
'_ast'=>time(),
);
//获取額外参数
preg_match_all('/<input name="([^" type="hidden" value="([^" />content, $out);
foreach($out[1] as $k=&gt;$v)
{
$param[$v] = $out[2][$k];
}

$re = array();
if($client-&gt;get('/weixin',$param))
{
if($type==2) //查找文章排名
{
//匹配字串为
<h4><a id="sogou_vr_11002601_title_2" href="http://mp.weixin.qq.com/s?__biz=MzA5ODE2OTYwMA==&amp;mid=200270633&amp;idx=4&amp;sn=db2642f26640871b1747e92fcd8070af&amp;3rd=MzA3MDU4NTYzMw==&amp;scene=6#rd" target="_blank">夏养小常识 让你轻松<em><!--red_beg-->祛湿<!--red_end--></em>又健脾</a></h4>
$patten = '/

foreach($result[1] as $k=&gt;$val)

return $k+1;

}
}
}

备注:微信排名变动比较大,所以排名的准确性比百度要低好多。本示例仅供参考!
