<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">那么这个模型和爬虫有什么关系呢？其实，爬虫可以认为是一个生产者，它不断从网站爬取数据，爬取到的数据就是食物；而所得数据需要消费者进行数据清洗，把有用的数据吸收掉，把无用的数据丢弃。<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">以上便是对生产者消费者模型的简单介绍了，下面针对本次爬取任务予以详细说明。<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">分析站点<pre style="margin-bottom:0px;padding-right:0px;padding-left:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;"><pre class="source-code" style="margin-bottom:0px;padding:15px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;background:rgb(243,244,245);"><code style="margin:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;"><span style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;color:rgb(153,115);">http://www.cfachina<span style="margin:0px;padding:0px;border:0px;font-style:inherit;font-variant:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;color:rgb(153,153,153);">.org/cfainfo/organbaseinfoServlet?all=personinfo<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">

<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">获取机构信息对应的网页数量<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">每个机构的数据量是不等的，幸好每个页面都包含了当前页面数及总页面数。使用以下代码即可获取页码数。<p style="margin-top:1em;margin-bottom:0px;border:0px;font-style:inherit;font-variant:inherit;font-weight:inherit;line-height:inherit;font-family:inherit;vertical-align:baseline;">
