python中requests请求的cookies值一般是jar包，如何将cookies值改为字典，此处运用了方法。举例如下：
import requests
response = requests.get(url)
resu = response.cookies
print resu #获取cookies,此处的cookies是jar包格式
result = requests.utils.dict_from_cookiejar(response.cookies)
print result #jar包转换为字典
或 print ({a.name : a.value for a in response.cookies})
