问题描述
如何使用Python的urllib2创建保持活跃的HTTP请求?
解决方案
使用库。这包括支持HTTP 1.1和keepalive的urllib2的HTTP处理程序:
>>> import urllib2
>>>来自urlgrabber.keepalive导入HTTPHandler
>>> keepalive_handler = HTTPHandler()
>>> opener = urllib2.build_opener(keepalive_handler)
>>> urllib2.install_opener(opener)
>>>
>>> fo = urllib2.urlopen('http://www.python.org')
注意:你应使用urlgrabber版本或更早版本,作为版本3.9.1中已删除模块
有一个针对Python 3的keepalive模块的。 / p>
How can I make a "keep alive" HTTP request using Python's urllib2?
解决方案
Use the urlgrabber library. This includes an HTTP handler for urllib2 that supports HTTP 1.1 and keepalive:
>>> import urllib2
>>> from urlgrabber.keepalive import HTTPHandler
>>> keepalive_handler = HTTPHandler()
>>> opener = urllib2.build_opener(keepalive_handler)
>>> urllib2.install_opener(opener)
>>>
>>> fo = urllib2.urlopen('http://www.python.org')
Note: you should use urlgrabber version 3.9.0 or earlier, as the keepalive module has been removed in version 3.9.1
There is a port of the keepalive module to Python 3.
