php curl 抓網頁數據問題,聽說內地神人很多,求神人解

Jun 06, 2016 pm 08:45 PM
php

因工作需求,需要抓取别人网站的数据,使用php + curl 但是遇到问题无解

听说内地的神人很多,请各位神人帮帮小弟,来自台湾的小弟已经爬文爬文三天了。


网址:http://www.cbssports.com/mlb/scoreboard

然后,选择下方正在比赛中的赛事,点选GAMETRACKER 就可以看到直播

问题来了

以这个网址为例:(当各位大大看到时,也许赛事已经结束了)

ttp://www.cbssports.com/mlb/gametracker/live/MLB_20140527_TB@TOR

小弟写的程序如下:

<code>$game=array();
$ch = curl_init(); 
$search1=$_GET['searcharg']; 
$url ="http://www.cbssports.com/mlb/gametracker/live/MLB_20140527_TB@TOR"; 


$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1132.57 Safari/536.11");
$data = curl_exec($ch);

curl_close($ch);
preg_match_all('/<span class="teamLocation">(.*?)/is',$data,$teamCity);
</span></code>
Copy after login

….(进行字符串解析)

目前已知问题:
不管是 「另存新檔」save as ,还是 检视原始档 ,一些该出现的html都没有出现,例如:
原网站为:

<code><tr id="current-pitcher">
    <td><img  src="/static/imghw/default1.png" data-src="http://sports.cbsimg.net/images/baseball/mlb/players/60x80/1961062.jpg" class="lazy" border="0" alt="php curl 抓網頁數據問題,聽說內地神人很多,求神人解" ></td>
    <td>
<span class="label">Pitcher:</span><span class="name"><b>M. Mariot</b> |  # 48 RP</span>
        <br>
        <a href="#" class="statOpt" data-playerid="1" data-position="pitcher">Game Stats</a>
        <div class="game-stats">0.1 IP</div>
        <div class="season-stats">0-0, 5.73 ERA, 11.0 IP, 9 K's, 6 BB</div>
    </td>
</tr>
</code>
Copy after login
Copy after login

不管是另存新档的网页或是curl 抓出来的结果为

<ul class="nav">
    <li class="active ingame" data-filter="current"><a href="#">Current Situation</a></li>
    <li data-filter="hitchart"><a href="#">Hitting Charts</a></li>
    <li data-filter="pitchchart"><a href="#">Pitching Charts</a></li>
</ul>
<div class="currentSituation ingame">
    <div class="batter-pitcher fLeft">
        <table>
            <tr id="current-pitcher">
                <td><img  src="/static/imghw/default1.png" data-src="http://sports.cbsimg.net/images/baseball/mlb/players/60x80/no-photo-available.jpg" class="lazy" border="0" alt="php curl 抓網頁數據問題,聽說內地神人很多,求神人解" ></td>
                <td>

                    <br>

                    <div class="game-stats">

&lt;p&gt;额,不知道你碰到了什么问题,不过我看了下就是简单的抓取,完全没问题啊。另外,解析HTML请不要在用正则了,推荐你用一下 phpQuery 这个库,PHP抓取利器。以你给的网址为例:&lt;/p&gt;

&lt;pre class='brush:php;toolbar:false;'&gt;include &quot;phpQuery.php&quot;;
phpQuery::newDocumentFile(&quot;http://www.cbssports.com/mlb/gametracker/live/MLB_20140527_TB@TOR&quot;);
echo pq(&quot;#current-pitcher&quot;)-&gt;html();
</pre><div class="contentsignin">Copy after login</div></div>

            <p class="answer fmt" data-id="1020000000522314">
                                    
</p>
<p>我遇到的问题 其实说穿了就是</p>

<p>...我用firbug 或 chrome debug时,所追踪的html 跟我 「检视原始档」和「另存新档」时所看到的资料不同:</p>

<p>目前有赛事  http://www.cbssports.com/mlb/gametracker/live/MLB_20140527_DET@OAK</p>

<p>神人求解</p>

                            
            <p class="answer fmt" data-id="1020000000522593">
                                    
</p>
<p>你想要抓去的html内容,是由javascript生成的,抓包工具都不会解析执行javascript的。<br>
解决方法就是用phantomjs,可以跑一个受脚本控制的,无界面的webkit。</p>
