Question

我收到了这个错误： io.UnsupoortedOperation：读取 我做了一些改变。我将此行img = Image.open(f)更改为img = Image.open(f, "rb")之后我收到此错误： ValueError：错误模式＆＃39; rb＆＃39; 这里的问题是什么？我该如何解决这个问题？

views.py

class LinkCreateView(CreateView):
    model = Link
    form_class = LinkForm

    def form_valid(self, form):
        hash = str(uuid.uuid1())
        with open("tmp_img_original_{}.png".format(hash), "wb") as f:
            res = requests.get(form.instance.url, stream=True)
            if not res.ok: raise Exception("URL'de dosya yok: 404")
            for block in res.iter_content(1024): f.write(block)

            img = Image.open(f, "rb")
            width, height = img.size
            img.thumbnail(get_size(width, height), Image.ANTIALIAS)
            img.save()

            djfile = File(f)

            form.img.save("img_tn_{}.png".format(hash), djfile, save=True)
            f.close()

        f = form.save(commit=False)
        f.rank_score = 0.0
        f.submitter = self.request.user
        f.save()

        return super(CreateView, self).form_valid(form)

答案是以模式＆＃34; wb +＆＃34;

打开文件

更改此

到

with open("tmp_img_original_{}.png".format(hash), "wb+") as f:

Django错误：io.UnsupportedOperation：read和ValueError：bad mode＆＃39; rb＆＃39;
