[PHP] 网盘搜索引擎-采集爬取百度网盘分享文件实现网盘搜索(二)

前情提要:最近使用PHP实现了简单的网盘搜索程序,并且关联了微信公众平台,名字是网盘小说。用户可以通过公众号输入关键字,公众号会返回相应的网盘下载地址。就是这么一个简单的功能,类似很多的网盘搜索类网站,我这个采集和搜索程序都是PHP实现的,全文和分词搜索部分使用到了开源软件xunsearch。

上一篇([PHP] 网盘搜索引擎-采集爬取百度网盘分享文件实现网盘搜索)中我重点介绍了怎样去获取一大批的百度网盘用户,这一篇介绍怎样获得指定网盘用户的分享列表。同样的原理,也是找到百度获取分享列表的接口,然后去循环就可以了。

 

查找分享接口

随便找一个网盘用户的分享页面,点击最下面的分页链接,可以看到发起的请求接口,这个就是获取分享列表的接口。

整个的请求url是这个 https://pan.baidu.com/pcloud/feed/getsharelist?t=1493892795526&category=0&auth_type=1&request_location=share_home&start=60&limit=60&query_uk=4162539356&channel=chunlei&clienttype=0&web=1&logid=MTQ5Mzg5Mjc5NTUyNzAuOTEwNDc2NTU1NTgyMTM1OQ==&bdstoken=bc329b0677cad94231e973953a09b46f

 

调用接口获取数据

使用PHP的CURL去请求这个接口,看看是否能够获取到数据。测试后发现,返回的是{"errno":2,"request_id":1775381927},并没有获取到数据。这是因为百度对header头信息里面的Referer进行了限制,我把Referer改成http://www.baidu.com,就可以获取到数据了。接口的参数也可以进行简化成 https://pan.baidu.com/pcloud/feed/getsharelist?&auth_type=1&request_location=share_home&start=60&limit=60&query_uk=4162539356

测试代码如下:

<?php
/*
* 获取分享列表
*/
class TextsSpider{
    /**
    * 发送请求
    */
    public function sendRequest($url,$data = null,$header=null){
        $curl = curl_init();
        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
        if (!empty($data)){
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
        }
        if (!empty($header)){
            curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
        }

        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
        $output = curl_exec($curl);
        curl_close($curl);
        return $output;
    }
}
$textsSpider=new TextsSpider();
$header=array(
    'Referer:http://www.baidu.com'
);
$str=$textsSpider->sendRequest("https://pan.baidu.com/pcloud/feed/getsharelist?&auth_type=1&request_location=share_home&start=60&limit=60&query_uk=4162539356",null,$header);
echo $str;

分享列表的json结果如下:

    "request_id": 1985680203,

                }
            ],
            "source_uid": "528742401",
            "source_id": "98963537",

            "tCnt": 184
        },
        {
            "source_uid": "528742401",
            "source_id": "152434783",
            "shorturl": "1qYdhFkC",

            "dCnt": 29,
            "tCnt": 345
        }
    ]
}

还是和上次一样,综合性的搜索站,可以把有用的数据都留下存住,我只是做个最简单的,就只要了标题title和shareid

每个分享文件的下载页面url是这样的:http://pan.baidu.com/share/link?shareid={$shareId}&uk={$uk} ,只需要用户编号和分享id就可以拼出下载url。

 

生成分页接口URL

假设用户最多分享了30000个,每页60个,可以分500页,这样url可以这样生成

<?php
/*
* 获取分享列表
*/
class TextsSpider{
    private $pages=500;//分页数
    private $start=60;//每页个数
    /**
    * 生成分页接口的url
    */
    public function makeUrl($rootUk){
        $urls=array();
        for($i=0;$i<=$this->pages;$i++){
            $start=$this->start*$i;
            $url="https://pan.baidu.com/pcloud/feed/getsharelist?&auth_type=1&request_location=share_home&start={$start}&limit={$this->start}&query_uk={$rootUk}";
            $urls[]=$url;
        }
        return $urls;
    }

}
$textsSpider=new TextsSpider();
$urls=$textsSpider->makeUrl(4162539356);
print_r($urls);

分页的url结果是这样的

Array
(
    [0] => https://pan.baidu.com/pcloud/feed/getsharelist?&auth_type=1&request_location=share_home&start=0&limit=60&query_uk=4162539356

数据表存储结构

CREATE TABLE `texts` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL DEFAULT '',
  `url` varchar(255) NOT NULL DEFAULT '',
  `time` int(10) unsigned NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `title` (`title`(250))
) ENGINE=MyISAM

 

 循环读取的时候,应该注意,每次间隔一定的时间,防止被封。
