urllib2.ProxyBasicAuthHandler用来挂载访问网页时的代理

Example 1

def build_opener(self):
        cookiejar = cookielib.FileCookieJar(cookiefile)
        cookie_handler = urllib2.HTTPCookieProcessor(cookiejar)
        redirect_handler = urllib2.HTTPRedirectHandler()
        #proxy_handler = urllib2.ProxyHandler()
        #proxy_auth_handker = urllib2.ProxyBasicAuthHandler()
        return urllib2.build_opener(cookie_handler, redirect_handler)

Example 2

def install_proxy():
    USE_PROXY=True
    import urllib2 
    global urlretrieve
    proxy_handler = urllib2.ProxyHandler({'http': 'http://proxy.cma-cgm.com:8080/'})
    proxy_auth_handler = urllib2.ProxyBasicAuthHandler()
    #proxy_auth_handler.add_password('realm', 'host', 'username', 'password')
    opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
    # This time, rather than install the OpenerDirector, we use it directly:
    urlretrieve=opener.open
