抓取北邮人论坛和水木社区校招信息的爬虫程序, 直接运行main.py即可，非常简洁，可以扩展
程序依赖以下第三方Python包：requests, BeautifulSoup, redis-py
爬虫根据自定义关键字先对校招信息进行过滤，然后存储到本机redis中。本机若有lamp环境，可直接从redis读取信息到web页面上即可，lamp环境中的php程序示例如下：
<!DOCTYPE html>
<html>
<head>
<title>Welcome to spider!</title>
<style>
body {
width: 35em;
margin: 0 auto;
}
a:visited { color: red; }
</style>
</head>
<body>
<?php
$rs_ip = '127.0.0.1';
$rs_port = 6379;
$rs = new Redis();
$rs->connect($rs_ip, $rs_port);
$ret = $rs->smembers('urls');
foreach($ret as $herf) {
echo $herf . "<br/>";
}
?>
</body>
</html>
效果截图：
此外，可以使用crontab或launchAgent(Mac OS X)把爬虫设定成定时任务，我的launchAgent如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/ DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

<array>
<string>/usr/local/bin/python</string>
<string>/Users/lzrak47/project/python/spider_python/main.py</string>
</array>

<true/>
<key>UserName</key>
<string>lzrak47</string>
<key>StartInterval</key>
<integer>3600</integer>
</dict>
</plist>
Enjoy it。
