I'm trying to use ghost.py to scrape a website using a script that works on my local machine:

import pdb
from ghost import Ghost
from urlparse import urlparse
import urllib2

...

def scrape(self, request):
    pdb.set_trace()
    page_url = request.DATA.get('url')
    page = urllib2.urlopen(page_url).read()
    original_url = urlparse(page_url)

    print original_url.scheme
    print original_url.netloc

    ghost = Ghost(wait_timeout = 90, display = True)
    page, resources = ghost.open(page_url)

    #use ghost.py to evaluate the javascript on the page
    result, resources = ghost.evaluate("""
                                var a = document.getElementsByTagName('img');
                                var SrcAlt = [];
                                for (var i = 0; i<a.length; i++){
                                    var src = a[i].getAttribute('src');
                                    var alt = a[i].getAttribute('alt');
                                    SrcAlt.push({"src": src, "alt": alt});
                                }
                                SrcAlt;
                            """)
    #counter = 0
    recs=[]
    for i in result:
        src=None
        alt=None
        try:
            # Gets the image src
            src = unicode(i[PyQt4.QtCore.QString(u'src')])
            try:
                # Gets the image alt tags
                alt = unicode(i[PyQt4.QtCore.QString(u'alt')])
            except:
                pass
        except:
            pass

However, when I add it to my web app, I get the obscenely long error below, and Python crashes. I've read every line of the error and can't figure out what the problem is. Any help would be amazing to let me know the first direction to take in making it work! Thank you!!!

回溯指向line 14of wgwt/web/notification_central/views.py,表示它正在尝试访问对象的userprofile属性(该AnonymousUser对象不存在)。

一种解决方法是确保您已登录...(这request.user是一个auth.User对象)。

request.user另一个是只有在不是匿名的情况下才走这条路,即:

if not isinstance(request.user, AnonymousUser):
    data = get_messages(request.user.userprofile)
