Python Mechanize - 如何在单个.open()调用中添加标头？

Question

我试图绕过没有API的某个服务,并决定尝试Mechanize(我通常使用urllib).

如何为一个open呼叫添加特定标头？

或者有没有办法构建一个具有自己的头的Request实例,然后让我的mechanize.Browser实例处理它？

browser = mechanize.Browser()
headers = [
    ('Accept', 'text/javascript, text/html, application/xml, text/xml, */*'),
    ('Content-type', 'application/x-www-form-urlencoded; charset=UTF-8'),
    ('User-Agent', 'Foobar'),
]

browser.addheaders = headers
# log in, do stuff, etc.

# here, for this one browser request, I need to add an AJAX header
browser.open('/a_url_to_ajax_post/', urllib.urlencode({'foo': 'bar'}))

我的解决方法是暂时修改addheaders列表,但是哇哇哇!

browser.addheaders.append(AJAX_HEADER)
browser.open('/admin/discounts', urllib.urlencode(pulled_params))
browser.addheaders.pop()

像这样做:

import mechanize
import urllib2

browser = mechanize.Browser()

# setup your header, add anything you want
header = {'User-Agent': 'Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1', 'Referer': 'http://whateveritis.com'}
url = "http://google.com"

# wrap the request. You can replace None with the needed data if it's a POST request
request = urllib2.Request(url, None, header)

# here you go
response = browser.open(request)

print response.geturl()
print response.read()
response.close()
