PycURL或任何其他python pakcage是否提供有关以下信息:
>查找
>连接时间
我想获得与此cURL命令相同的信息(无需使用子过程调用该命令):
命令
curl -s -w '\nLookup time:\t%{time_namelookup}\nConnect time:\t%{time_connect}\nPreXfer time:\t%{time_pretransfer}\nStartXfer time:\t%{time_starttransfer}\n\nTotal time:\t%{time_total}\n' -o /dev/null https://*.com/
输出:
Lookup time: 0.029
Connect time: 0.144
PreXfer time: 0.144
StartXfer time: 0.263
Total time: 0.803
解决方法:
是的,PyCurl提供了信息.您可以使用pycurl导出信息.它可以提供很多细节,而不仅仅是您提到的细节.
这是一个示例代码,可用于导出相同的信息:
import pycurl
from io import BytesIO
buffer = BytesIO()
c = pycurl.Curl()
c.setopt(c.URL, 'https://*.com/')
c.setopt(c.WRITEDATA, buffer)
c.perform()
body = buffer.getvalue()
print('TOTAL_TIME: %f' % c.getinfo(c.TOTAL_TIME))
print('CONNECT_TIME: %f' % c.getinfo(c.CONNECT_TIME))
print('PRETRANSFER_TIME: %f' % c.getinfo(c.PRETRANSFER_TIME))
print('STARTTRANSFER_TIME: %f' % c.getinfo(c.STARTTRANSFER_TIME))
c.close()
结果如下:
TOTAL_TIME: 2.252639
CONNECT_TIME: 0.331571
PRETRANSFER_TIME: 0.331634
STARTTRANSFER_TIME: 0.638206
