python解析ua

一个非常神奇的包可以帮助我们优雅的解析浏览器的UA，他的名字叫做user_agents

pip install pyyaml ua-parser user-agents

>>>ua_string='Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B179 Safari/7534.48.3'

>>># 浏览器属性

>>>user_agent=parse(ua_string)

>>>user_agent.browser

Browser(family=u'Mobile Safari',version=(5,1),version_string='5.1')

>>>user_agent.browser.family

u'Mobile Safari'

>>>user_agent.browser.version

(5,1)

>>>user_agent.browser.version_string

'5.1'

>>># 操作系统属性

>>>user_agent.os

OperatingSystem(family=u'iOS',version=(5,1),version_string='5.1')

>>>user_agent.os.family

u'iOS'

>>>user_agent.os.version

(5,1)

>>>user_agent.os.version_string

'5.1'

>>># 设备属性

>>>user_agent.device

Device(family=u'iPhone',brand=u'Apple',model=u'iPhone')

>>>user_agent.device.family

u'iPhone'

>>>user_agent.device.brand

u'Apple'

>>>user_agent.device.model

u'iPhone'

>>>

>>>str(user_agent)

'iPhone / iOS 5.1 / Mobile Safari 5.1'

批量解析：采用apply函数

• data['user_agent'] = data['ua'].apply(lambda x:parse(x))
