Question

我正在尝试使用漂亮的汤从链接中提取数据...目前其失败的身份验证如下所示。我如何验证链接，我知道应该登录的服务器...在哪里提供服务器路径以及如何验证链接？

from bs4 import BeautifulSoup as bs
import argparse
import urllib
import urllib2
import getpass
import re
import requests

def update (url):
    print url
    r = requests.get(url)
    html = r.text
    soup = bs(html)
def main ():
    #For logging
    print "test"
    parser = argparse.ArgumentParser(description='This is the update.py script created by test')
    parser.add_argument('-u','--url',action='store',dest='url',default=None,help='<Required> url link',required=True)
    results = parser.parse_args()# collect cmd line args
    url = results.url
    #print url
    update(url)
if __name__ == '__main__':
    main()

错误： -
