How do I set headers using python's urllib?

问题

I am pretty new to python\'s urllib. What I need to do is set a custom header for the request being sent to the server. Specifically, I need to set the Content-type and Authorizations headers. I have looked into the python documentation, but I haven\'t been able to find it.

回答1:

adding HTTP headers using urllib2:

from the docs:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('Referer', 'http://www.python.org/')
resp = urllib2.urlopen(req)
content = resp.read()

回答2:

For both Python 3 and Python 2, this works:

try:
    from urllib.request import Request, urlopen  # Python 3
except ImportError:
    from urllib2 import Request, urlopen  # Python 2

req = Request('http://api.company.com/items/details?country=US&language=en')
req.add_header('apikey', 'xxx')
content = urlopen(req).read()

print(content)

回答3:

Use urllib2 and create a Request object which you then hand to urlopen. http://docs.python.org/library/urllib2.html

I dont really use the "old" urllib anymore.

req = urllib2.Request("http://google.com", None, {'User-agent' : 'Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5'})
response = urllib2.urlopen(req).read()

untested....

For multiple headers do as follow:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('param1', '212212')
req.add_header('param2', '12345678')
req.add_header('other_param1', 'sample')
req.add_header('other_param2', 'sample1111')
req.add_header('and_any_other_parame', 'testttt')
resp = urllib2.urlopen(req)
content = resp.read()
