HTTP 错误 999：请求被拒绝

我正在尝试使用 BeautifulSoup 从 LinkedIn 抓取一些网页，但不断收到错误“HTTP 错误 999：请求被拒绝”。有没有办法避免这个错误。如果您查看我的代码，我尝试过 Mechanize 和 URLLIB2，两者都给了我相同的错误。

    params = {'page_num':y}

    url_parts = list(urlparse.urlparse(url))
    query = dict(urlparse.parse_qsl(url_parts[4]))
    query.update(params)

    url_parts[4] = urllib.urlencode(query)
    y = urlparse.urlunparse(url_parts)
    #print y



    #url = urllib2.urlopen(y)
    #f = urllib2.urlopen(y)

    op = mechanize.Browser() # use mecahnize's browser
    op.set_handle_robots(False) #tell the webpage you're not a robot
    j = op.open(y)
    #print op.title()


    #g = URLGrabber()
    #data = g.urlread(y)
    #data = fo.read()

    soup1 = BeautifulSoup(y)
    print soup1

您应该使用领英 REST API https://developer.linkedin.com/docs/rest-api，直接或使用python-linkedin https://pypi.python.org/pypi/python-linkedin。它允许直接访问数据，而不是尝试抓取大量 JavaScript 的网站。
