python 3调用百度OCR API实现剪贴板文字识别

本程序调用百度ocr api对剪贴板的图片文字识别，配合capturescreen软件，可快速识别文字。

#!python3

import os, io, sys, json, socket

from pil import imagegrab
 
socket.setdefaulttimeout(30)

  host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=%s&client_secret=%s' % (apikey, secret_key)
  req = urllib.request.request(host)
  req.add_header('content-type', 'application/json; charset=utf-8')
  res = urllib.request.urlopen(req)
  content = res.read()
  if (content):
    o = json.loads(content.decode())
    return o['access_token']
  return none

  im = imagegrab.grabclipboard()
  if im is none:
    print('no image in clipboard')
    return
  print('image size: %sx%s\n>>>\n' % (im.size[0], im.size[1]))
  mf = io.bytesio()
  im.save(mf, 'jpeg')
  mf.seek(0)
  buf = mf.read()
  b64 = base64.encodebytes(buf)

    data = urllib.parse.urlencode({'image' : b64}).encode()
    req = urllib.request.request(url, method='post')
    req.add_header('content-type', 'application/x-www-form-urlencoded')
