Python:requests.exceptions.ConnectionError: ('Connection aborted.' , BadStatusLine ("' '",))

Question

当我尝试从网站下载大量页面时遇到此错误。该脚本是从其他几个脚本拼凑而成的，看来我对Python和编程比较陌生。

Python版本为3.4.3，Requests版本为2.7.0。

这是脚本:

import requests
from bs4 import BeautifulSoup
import os.path

s = requests.session()
login_data = {'dest': '/','user': '******', 'pass': '******'}
header_info={'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0'}
url='http://www.oxfordreference.com/LOGIN'
s.post(url,data=login_data,headers=header_info)

for i in range(1,100):
    downprefix='http://www.oxfordreference.com/view/10.1093/acref/9780198294818.001.0001/acref-9780198294818-e-'
    downurl=downprefix+str(i)
    r=s.get(downurl,headers=header_info,timeout=30)
    if r.status_code==200:
        soup=BeautifulSoup(r.content,"html.parser")
        shorten=str(soup.find_all("div", class_="entryContent"))
        fname='acref-9780198294818-e-'+str(i)+'.htm'
        newname=os.path.join('shorten',fname)
        htmfile=open(newname,'w',encoding="utf_8")
        htmfile.write(shorten)
        htmfile.close()
        print('Success in '+str(i))
else:
        print('Error in '+str(i))
        errorfile=open('errors.txt','a',encoding="utf_8")
        errorfile.write(str(i))
        errorfile.write('\n')
        errorfile.close()

与您通话的主持人没有正确回应。这通常发生在您尝试使用 http 连接到 https 服务时，但也可能有很多其他情况。

检查发生了什么的最好方法可能是获取网络流量分析器(例如 wireshark)并查看连接。
