如何使用python的urllib设置标头？

Question

我对python的urllib很新.我需要做的是为发送到服务器的请求设置自定义标头.具体来说,我需要设置Content-type和Authorizations标头.我查看了python文档,但是我找不到它.

Answer 1

使用urllib2添加HTTP标头:

来自文档:

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

Answer 2

对于Python 3和Python 2,这适用于:

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)

Answer 3

使用urllib2并创建一个Request对象,然后将其移交给urlopen. http://docs.python.org/library/urllib2.html

我不再使用"旧"urllib了.

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()
