Question

media.py发生错误，看起来我的网址是无。但我不明白为什么。如何将url等于用户发布的url？如果你看到我的views.py，我试着像那样设置它。 url等于self.request.GET.get（'url'）。我做错了吗？

media.py 导入json import urllib2 来自urllib2导入请求来自goose import Goose

def get_content(url):
    """This function is intended to return content from url.
    :param url: URL to get content
    :return: The response from url
    """
    req = urllib2.Request(url, headers={'User-Agent': "Magic Browser"})
    response = urllib2.Request.urlopen(req).read()
    return response 


def extract(url):
    url = get_content(url)
    g = Goose()
    article = g.extract(url=url)
    resposne = {'image':article.top_image.src}
    return json.dumps(resposne)

views.py

class PostCreateView(CreateView):

     model = Post
     form_class = PostForm
     template_name = 'main/add_post.html'

     def form_valid(self, form):
            self.object = form.save(commit=False)
            # any manual settings go here
            self.object.moderator = self.request.user
            url = self.request.GET.get('url')
            image = extract(url)
            self.object.save()
            return HttpResponseRedirect(reverse('post', args=[self.object.slug]))

     @method_decorator(login_required)
     def dispatch(self, request, *args, **kwargs):

            return super(PostCreateView, self).dispatch(request, *args, **kwargs)

在views.py中，请执行以下操作：

def form_valid(self, form):
    self.object = form.save(commit=False)
    # any manual settings go here
    self.object.moderator = self.request.user
    url = self.request.GET.get('url', False)
    if url:
        image = extract(url)
    self.object.save()
    return HttpResponseRedirect(reverse('post', args=[self.object.slug]))

'NoneType'对象没有属性'strip' - 从发布的url中提取图像
