python - 枕头 OSError : cannot identify image file <_io. BytesIO 对象在 0x02345ED8>

Question

我正在尝试从 http 请求中获取 jpeg、gif 等，但出现错误。这是代码的一部分:

def printimg(url):

    http = httppoolmgr()

    file = http.request('GET',url).read()
    r_data = binascii.unhexlify(file)
    stream = io.BytesIO(r_data)
    img = Image.open(stream)
    #img = Image.open(file)

    return img

返回的错误码是:

  File "C:\Python34\lib\site-packages\pillow-2.5.3-py3.4-win32.egg\PIL\Image.py"
, line 2256, in open
OSError: cannot identify image file <_io.BytesIO object at 0x02345ED8>

有没有人遇到过这种问题？

确定这个解决方案:

def populate(self):

    http = httppoolmgr()
    array = xmltohash(getrack(http,'618cd2a4a2a1740a9f46e4f367ef88f3'))

    for row in range(len(array)):
        url = str((array[row]),"utf-8").split("$#$")[3]
        title = str((array[row]),"utf-8").split("$#$")[1]
        response = requests.get(url)
        img = Image.open(io.BytesIO(response.content))
        img.save("picture/%s.png" % row)
        self.foto = PhotoImage(file="picture/%s.png" % row)

        pic=Label(self.frame, image=self.foto, name=str(row))
        pic.image = self.foto
        pic.grid(row=row, column=0, sticky=W)
        t=str((array[row]),"utf-8").split("$#$")[1]
        Label(self.frame, text=t).grid(row=row, column=1, sticky=W)

就我的观点而言，没有任何意义为什么以前的代码不起作用，但我猜 python 或 tkinter 不喜欢转换很多选项 woinw 不，我知道 :D
