问题描述
我正试图解决某种没有API的服务,因此决定尝试机械化(我通常使用urllib).
I'm trying to get around a certain service not having an API and decided to try Mechanize (I normally use urllib).
如何为一个open
呼叫添加特定的标头?
How do I add a specific header for one open
call?
或者有没有一种方法可以用自己的标头构造一个Request实例,然后让我的mechanize.Browser
实例处理它?
Or is there a way to construct a Request instance with its own headers, then have my mechanize.Browser
instance handle it?
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'}))
我的解决方法是临时修改addheaders列表,但是哇,真丑!
My workaround is to temporarily modify the addheaders list, but wow that is ugly!
browser.addheaders.append(AJAX_HEADER)
browser.open('/admin/discounts', urllib.urlencode(pulled_params))
browser.addheaders.pop()
推荐答案
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()
