Mechanizeフォームの提出により、.read（）が試行されたときに「アサーションエラー」が発生する

Question

私はpythonでウェブクロールプログラムを作成していますが、mechanizeを使用してログインできません。サイト上のフォームは次のようになります。

だから、

<form method="post" action="PATLogon"> 
    <h2 align="center"><img src="/myaladin/images/aladin_logo_rd.gif"></h2> 
    <!-- ALADIN Request parameters --> 
    <input type=hidden name=req value="db"> 
    <input type=hidden name=key value="PROXYAUTH"> 
    <input type=hidden name=url value="http://eebo.chadwyck.com/search"> 
    <input type=hidden name=lib value="8">  
<table> 
<tr><td><b>Last Name:</b></td> 
    <td><input name=LN size=20 maxlength=26></td> 
<tr><td><b>University ID or Library Barcode:</b></td> 
    <td><input type=password name=BC size=20 maxlength=21></td> 
<tr><td><b>Institution:</b></td> 
    <td><select name="INST"> 
     <option value="??">Select University ----</option> 
     <option value="AU">American</option> 
     <option value="CU">Catholic</option> 
     <option value="DC">District of Columbia</option> 
     <option value="GA">Gallaudet</option> 
     <option value="GM">George Mason</option> 
     <option value="GW">George Washington</option> 
     <option value="GT">Georgetown</option> 
     <option value="MU">Marymount</option> 
     <option value="TR">Trinity</option> 
     </select> 
     &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
     <input type="submit" value="GO"> 
    </td></tr></table></form> 

、私は適切にすべてを設定することができていますが、フォームを送信し、私はエラーが残っています応答を印刷しようとするの。次のように私のコードは次のとおりです。

import mechanize 
import time 
br = mechanize.Browser() 
br.set_handle_robots(False) 

def connect(): 
    # connection information              
    url = "https://www.aladin.wrlc.org/Z-WEB/Aladin?req=db&key=PROXYAUTH&lib=8&\url=http://eebo.chadwyck.com/search" 
    br.open(url) 
    time.sleep(0.5) 
    br.select_form(nr=0) 
    br["LN"] = "Reese" 
    br["BC"] = "myPassword" 
    br["INST"] = ["AU"] 
    response = br.submit() 
    print response.getheaders() 

私はここに来るのエラーは次のとおりです。

>>> eebolib.connect() 
Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "eebolib.py", line 28, in connect 
    print response.read() 
    File "build/bdist.macosx-10.5-fat3/egg/mechanize/_response.py", line 190, in read 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 349, in read 
    data = self._sock.recv(rbufsize) 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 553, in read 
    if self.length is not None: 
    File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/httplib.py", line 1282, in read 
    if amt is None or amt > self._line_left: 
AssertionError 

誰もがこの上でいくつかの援助を提供することができた場合は、私が最も感謝だろう。

これは私が見つけた解決策である：

import mechanize,urllib,ClientForm,cookielib,re,os,time 
from BeautifulSoup import BeautifulSoup 

cookies = mechanize.CookieJar() 
opener = mechanize.build_opener(mechanize.HTTPCookieProcessor(cookies)) 
headers = [("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"),\ 
      ("Accept-Charset","ISO-8859-1,utf-8;q=0.7,*;q=0.7"),\ 
      ("Accept-Encoding","gzip, deflate"),\ 
      ("Accept-Language","en-us,en;q=0.5"),\ 
      ("Connection","keep-alive"),\ 
      ("Host","www.aladin.wrlc.org"),\ 
      ("Referer","https://www.aladin.wrlc.org/Z-WEB/Aladin?req=db&key=PROXYAUTHlib=8url=http://eebo.chadwyck.com/search"),\ 
      ("User-Agent","Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:5.0) Gecko/20100101 Firefox/5.0")] 
opener.addheaders = headers 
mechanize.install_opener(opener) 
params = urllib.urlencode({'LN':'myLN','BC':'myBC','INST':'myINST',\ 
          'req':'db','key':'PROXYAUTH','lib':'8',\ 
          'url':'http://eebo.chadwyck.com/search'}) 
mechanize.urlopen("https://www.aladin.wrlc.org/Z-WEB/PATLogon",params) 

希望、これはいつか誰かを助け:)
