PHP+fiddler抓包采集微信文章阅读数点赞数的思路详

简介:

分析接口知道要获取文章阅读数和点赞数必须有key和uin这两个关键参数,不同公众号key不一样(据说有万能微信key,不懂怎么搞到),同一个公众号key大概半小时会过期

提交链接获取文章阅读量api

思路:

1.将客户端请求阅读量接口的请求拦截转发到自己服务器,这样就可以获取到key ,用__biz关联缓存半小时

2.提交文章链接进行查询时,服务器从文章链接里获取__biz,查询是否缓存了当前公众号对应的key,有的话进行第3步,没有进行第4步。

3.curl请求https://mp.weixin.qq.com/mp/getappmsgext? 接口获取数据

4.key不存在时,通知客户端重定向到该url(通知用websocket通知或者客户端ajax轮询,需要用抓包工具修改文章详情页代码让其跳转到中间页面待命,打开文章页面后隔几秒跳回中间页)并暂停程序几秒等待客户端更新key,此时客户端提交了新的key,用其进行查询

实现

1.抓包

此接口就是获取阅读量的接口,参数如下图

2.将此接口拦截转发到自己服务器,点击 rules- customize rules  在OnBeforeRequest(正式请求之前执行的函数)加上

if (oSession.fullUrl.Contains("mp.weixin.qq.com/mp/getappmsgext"))
 {
  oSession.oRequest["Host"]= 'ccc.aaa.com' ;
 }

效果,可以看到此接口已经被转发

3.服务端缓存key,代码以PHP为例

 public function saveKey(Request $request)
  {
    $__biz = $request->param('__biz',0);
    $data['uin'] = $request->param('uin',0);
    $data['key'] = $request->param('key',0);
    Cache::set($__biz,$data,30 * 60);
    return 'ok';
  }

4.提交文章链接查询API代码

public function getReadNum(Request $request)
  {
    $url = $request->param('url');
    parse_str(parse_url($url)['query'], $param);
    $__biz = $param['__biz'];
    $key_data = Cache::get($__biz);
    if (empty($key_data))
      return 'no key';
    $uin = $key_data['uin'];
    $key = $key_data['key'];
    $param['uin'] = $uin;
    $param['key'] = $key;
    $param['wxtoken'] = "777";
    $wechat_url = "https://mp.weixin.qq.com/mp/getappmsgext?" . http_build_query($param);
    //dump($wechat_url);
    $data = array(
      'is_only_read' => 1,
      'is_temp_url' => 0,
      'appmsg_type' => 9,
    );
    $res = $this->get_url($wechat_url,$data);
    return $res;
  }
function get_url($url,$data)
  {
    $ifpost = 1;//是否post请求
    $datafields = $data;//post数据
    $cookiefile = '';//cookie文件
    $cookie = '';//cookie变量
    $v = false;
 
    //模拟http请求header头
    $header = array("Connection: Keep-Alive","Accept: text/html, application/xhtml+xml, */*", "Pragma: no-cache", "Accept-Language: zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.3","User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.116 Safari/537.36 QBCore/4.0.1278.400 QQBrowser/9.0.2524.400 Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2875.116 Safari/537.36 NetType/WIFI MicroMessenger/7.0.5 WindowsWechat");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HEADER, $v);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    $ifpost && curl_setopt($ch, CURLOPT_POST, $ifpost);
    $ifpost && curl_setopt($ch, CURLOPT_POSTFIELDS, $datafields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    $cookie && curl_setopt($ch, CURLOPT_COOKIE, $cookie);//发送cookie变量
    $cookiefile && curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);//发送cookie文件
    $cookiefile && curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);//写入cookie到文件
    curl_setopt($ch,CURLOPT_TIMEOUT,60); //允许执行的最长秒数
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    $ok = curl_exec($ch);
    curl_close($ch);
    unset($ch);
    return $ok;
  }
