如何使用 python 的 urllib 设置标题？

我对巨蟒的即兴表演还很陌生。我需要做的是为发送到服务器的请求设置一个自定义头。具体来说，我需要设置 Content-type 和 Authorization 头。我已经查看了 Python 文档，但是还没有找到它。

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....

最佳答案

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()

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)

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()
