想法是使用BeautifulSoup 定位脚本,并使用正则表达式模式查找fvRequests.setValue() 调用并提取第三个参数的值:
import re
from bs4 import BeautifulSoup
import requests
pattern = re.compile(r"fvRequests\.setValue\(\d+, \d+, '?(\w+)'?\);")
response = requests.get("http://www.webpagetest.org/breakdown.php?test=150325_34_0f581da87c16d5aac4ecb7cd07cda921&run=2&cached=0")
soup = BeautifulSoup(response.content)
script = soup.find("script", text=lambda x: x and "fvRequests.setValue" in x).text
print(re.findall(pattern, script))
打印:
[u'css', u'7', u'flash', u'0', u'font', u'0', u'html', u'14', u'image', u'80', u'js', u'35', u'other', u'14']
你可以更进一步,将列表打包成一个字典(解决方案取自here):
dict(zip(*([iter(data)] * 2)))
会产生:
{
'image': '80',
'flash': '0',
'js': '35',
'html': '14',
'font': '0',
'other': '14',
'css': '7'
}
