接着上一遍，在用Selenium+phantomjs 抓取数据过程中发现，有时候抓取不到，所以又测试了用Selenium+浏览器驱动的方式：具体代码如下：

#coding=utf-8

        configfile = os.path.join(os.getcwd(),'config.conf')
        cf = IniFile.ConfigFile(configfile)
        IEDriverServer = cf.GetValue("section", "IEDriverServer")
        #每抓取一页数据延迟的时间，单位为秒，默认为5秒
        self.pageDelay = 5
        pageInteralDelay = cf.GetValue("section", "pageInteralDelay")
        if pageInteralDelay:
            self.pageDelay = int(pageInteralDelay)

        os.environ["webdriver.ie.driver"] = IEDriverServer
        self.driver = webdriver.Ie(IEDriverServer)
