Question

我正试图获得教育、科学和技术部的预报。

我可以在库勒/REST客户(国际调查工具)工作,使预先认证成为可能。

但是,使用lli2,似乎不支持这种说法,我无法找到扭转这种局面的办法。

感谢:

在此,根据<代码>urllib2.HTTPBasicAuthHandler的代码,采用一种简单的防范性吉大港山区基本手法。除<代码>Authorization的头盔将添加到every申请中与URL匹配。请注意,应当使用<代码>。 HTTPPasswordMgrWithDefaultReal。这是因为,由于你再次成为先发制人,因此在的挑战中没有任何回头。

class PreemptiveBasicAuthHandler(urllib2.BaseHandler):

        def __init__(self, password_mgr=None):
                if password_mgr is None:
                        password_mgr = urllib2.HTTPPasswordMgrWithDefaultRealm()
                self.passwd = password_mgr
                self.add_password = self.passwd.add_password

        def http_request(self,req):
                uri = req.get_full_url()
                user, pw = self.passwd.find_user_password(None,uri)
                #logging.debug( ADDING REQUEST HEADER for uri (%s): %s:%s ,uri,user,pw)
                if pw is None: return req

                raw = "%s:%s" % (user, pw)
                auth =  Basic %s  % base64.b64encode(raw).strip()
                req.add_unredirected_header( Authorization , auth)
                return req

类似于@thom-nichols的回答;但次分类HTTPBasicAuthHandler也处理HTTPS的要求。

import urllib2
import base64

class PreemptiveBasicAuthHandler(urllib2.HTTPBasicAuthHandler):
       Preemptive basic auth.

    Instead of waiting for a 403 to then retry with the credentials,
    send the credentials if the url is handled by the password manager.
    Note: please use realm=None when calling add_password.   
    def http_request(self, req):
        url = req.get_full_url()
        realm = None
        # this is very similar to the code from retry_http_basic_auth()
        # but returns a request object.
        user, pw = self.passwd.find_user_password(realm, url)
        if pw:
            raw = "%s:%s" % (user, pw)
            auth =  Basic %s  % base64.b64encode(raw).strip()
            req.add_unredirected_header(self.auth_header, auth)
        return req

    https_request = http_request

这里是处理一个不送你401<>/code>的jenkins服务器的例子。使用<代码>urllib2.install_ opener使事情变得容易。

jenkins_url = "https://jenkins.example.com"
username = "johndoe"
api_token = "some-cryptic-value"

auth_handler = PreemptiveBasicAuthHandler()
auth_handler.add_password(
    realm=None, # default realm.
    uri=jenkins_url,
    user=username,
    passwd=api_token)
opener = urllib2.build_opener(auth_handler)
urllib2.install_opener(opener)

根据需要何种认证,你可以人工发送授权书负责人,在你发出机构之前添加他们的请求。
