使用Python 3.4加载到tkinter时出现枕头错误

Question

I am loading an image from a server, and I keep getting this error when I use Base64 on the data.

Here's my code:

import tkinter as tk
from PIL import ImageTk
root = tk.Tk()
import urllib.request
URL = "https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSm7eLMSp4NbjGwkjU3rPokWaQI6224lQCR1qIIGIfldm4M0TgY0JKTGQLQ"
u = urllib.request.urlopen(URL)
raw_data = u.read()
u.close()
import base64
b64_data = base64.encodestring(raw_data)
image = ImageTk.PhotoImage(data=b64_data)
label = tk.Label(image=image)
label.pack()

I get this error:

Traceback (most recent call last):
   File "C:/testt.py", line 11, in <module>
image = ImageTk.PhotoImage(data=b64_data)
   File "C:\Python34\lib\site-packages\PIL\ImageTk.py", line 88, in __init__
image = Image.open(BytesIO(kw["data"]))
   File "C:\Python34\lib\site-packages\PIL\Image.py", line 2287, in open
   % (filename if filename else fp))
OSError: cannot identify image file <_io.BytesIO object at 0x0000000003152048>

Your code works, if you remove some of it. The base64 encoding is not needed:

import tkinter as tk
from PIL import ImageTk
import urllib.request

root = tk.Tk()

URL = "https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcSm7eLMSp4NbjGwkjU3rPokWaQI6224lQCR1qIIGIfldm4M0TgY0JKTGQLQ"
u = urllib.request.urlopen(URL)
raw_data = u.read()
u.close()

image = ImageTk.PhotoImage(data=raw_data)
label = tk.Label(image=image)
label.pack()
tk.mainloop()

Result:
