AttributeError:“module”对象在urllib3中没有属性“urlopen”

Question

我也查过其他帖子，但解决办法似乎没有奏效。我一直得到AttributeError:“module”对象没有属性“urlopen”错误。如果你有什么想法，我会非常感激的。在

from lxml import html
import requests
import urllib3

page = requests.get('http://www.sfbos.org/index.aspx?page=18701')
tree = html.fromstring(page.content)

#This will create a list of buyers:
proposal_doc_date = tree.xpath('//ul[@title="Date List"]/li/a/text()')
pdf_url = tree.xpath('//ul[@title="Date List"]/li/a/@href')

print 'Proposal Date ', proposal_doc_date
print 'Proposal PDF ', pdf_url

def download_pdf(url_list):
    for i in url_list:
        response = urllib3.urlopen(i)
        file = open(proposal_doc_date[i], 'wb')
        file.write(response.read())
        file.close()
        print("Completed")

download_pdf(pdf_url)

Answer 1

urlopen似乎是urllib3的方法。connectionpool.HTTPConnectionPool班级
