<h1 id="天眼查爬虫">天眼查爬虫<a class="anchor-link" href="#天眼查爬虫">¶</a></h1><p>2018-1-21<br/>
marking的同事跑过来求帮忙，能不能通过爬虫帮他，根据会议收集表格中，人员名单所填写的公司名称添加一列行业信息。<br/>
他目前是手工到天眼输入公司名称，然后再取出觉得匹配的公司，最后在找到行业分类。但是人员明天太多了，做这么枯燥的工作他要疯了:(<br/>
我觉得这个应该比较简单，答应他帮他写个爬虫</p>
<h6 id="确定爬取方式">确定爬取方式<a class="anchor-link" href="#确定爬取方式">¶</a></h6><p>selenium是个自动化测试工具，他可以通过浏览器来模拟各种操作实现测试页面功能<br/>
BeautifulSoup是个爬虫常用的Dom解析工具<br/>
lxml提供了xpath获取方法，强烈推荐通过xpath访问节点，配合Chrome的inspect工具中的 copy xpath可以节省大量的节点获取工作量</p>
<h6 id="安装必要的工具">安装必要的工具<a class="anchor-link" href="#安装必要的工具">¶</a></h6><p>pip install selenium<br/>
pip install lxml<br/>
pip install beautifulsoup4<br/>
下载最新的chromedriver<br/>
<a href="http://chromedriver.storage.googleapis.com/index.html">http://chromedriver.storage.googleapis.com/index.html</a><br/>
我是mac 安装到/usr/local/bin/目录下，然后运行 chromedriver -v查看是否安装好了</p>
<h6 id="常见问题">常见问题<a class="anchor-link" href="#常见问题">¶</a></h6><ol>
<li>公司名称不存在；在天眼搜里面找不到公司名称就在程序中填写none或者其他的字符说明 </li>
<li>相似公司很多个不确定怎么选；这个比较不好处理，现在是取天眼搜中查找到的top 1 记录 我想人选择的话可能会根据与会者所在地配合来查找吧，例如是在北京参加的，那么就有限找北京的同名（名称相似）的公司 </li>
<li>天眼里面找到的母公司下面有多个子公司，导致鼠标点击不到连接，必须拉滚动条才能解决问题 </li>
