新浪微博登录代码改造

Question

你好,bobby新浪微博的登录验证码改了,网上的这个是基于python2.7的,这里改造怎么报错了?

2.7代码

import StringIO

im0 = Image.open(StringIO.StringIO(browser.get_screenshot_as_png()))

改造后代码

from io import StringIO
im0 = Image.open(StringIO.read(browser.get_screenshot_as_png().decode('ascii')))

报错

File "D:/python/splider/ArticleSplider/ArticleSplider/login.py", line 48, in getType
    im0 = Image.open(StringIO.read(browser.get_screenshot_as_png().decode('ascii')))
UnicodeDecodeError: 'ascii' codec can't decode byte 0x89 in position 0: ordinal not in range(128)

可是的源码用的就是asciiencode的为啥decode会出错

def get_screenshot_as_png(self):
   """
   Gets the screenshot of the current window as a binary data.

   :Usage:
       driver.get_screenshot_as_png()
   """
   return base64.b64decode(self.get_screenshot_as_base64().encode('ascii'))

 不是utf8encode的应该不是这么解码的吧,如果有必要我提供下源码给您看下

老师,还是一样的报错,

im0 = Image.open(StringIO.read(browser.get_screenshot_as_png().decode('utf8')))

UnicodeDecodeError: 'utf-8' codec can't decode byte 0x89 in position 0: invalid start byte

亲 这个是python的字符编码问题 你把decode ascii改为用utf8编码decode试试呢
