使用自动化测试框架selenium，批量的进行截图

最近在做一个自动化的电子邮件系统，实现是在outlook客户端能够接受html的邮件。

但是，由于我做的报表使用fusioncharts做的，fusioncharts框架是一个js图表库，所有的图表都是通过javascript来渲染出来的，

由于outlook不能支持js，所以只能将做好的图表页面截图，放入HTML页面中来发送。

截图的代码如下：

from datetime import datetime
import json
import urllib2

from selenium import webdriver
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.wait import WebDriverWait


def web_spider(logDebug,url="http://www.baidu.com",enable_proxy=True,proxy_address='http://baidu.com:8080'):   
#     logDebug=open(logs_path,'a')
    proxy_handler = urllib2.ProxyHandler({"http" : proxy_address})  
    null_proxy_handler = urllib2.ProxyHandler({})  
    if enable_proxy:  
        opener = urllib2.build_opener(proxy_handler)  
    else:  
        opener = urllib2.build_opener(null_proxy_handler)  
    content=""
    try:
        urllib2.install_opener(opener) 
        headers = {'User-Agent':'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.6) Gecko/20091201 Firefox/3.5.6'}
        req = urllib2.Request(url =url ,headers = headers)
    #     f=open("email.txt",'w+')
        content=urllib2.urlopen(req).read()
        content.decode("utf-8",'ignore').encode('utf-8')
    
    #     f.write(content)
    #     f.close()
    except Exception,e:
        logDebug.write("%s:web spider exception,%s\n" %(datetime.now().strftime('%Y%m%d-%H%M%S'),e))
        
        pass
    return content
