这篇文章主要为大家详细介绍了Python3实现腾讯云OCR识别，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

废话不多说，在网上找了下腾讯云 OCR识别的，示例不多，用Python的还是Python2.7，花了点时间改成Python3的。
先上图，腾讯自己的示例图：

Python3实现腾讯云OCR识别

下面是代码：

									import requests

									import hmac

									import hashlib

									import base64

									import time

									import random

									import re

									appid = "你自己的appid"

									bucket = " 这个是优图上面的，可以不填" #参考本文开头提供的链接

									secret_id = "填自己的" #参考官方文档

									secret_key = "填自己的" #同上

									expired = time.time() + 2592000

									onceExpired = 0

									current = time.time()

									rdm = ''.join(random.choice("0123456789") for i in range(10))

									userid = "0"

									fileid = "tencentyunSignTest"

									info = "a=" + appid + "&b=" + bucket + "&k=" + secret_id + "&e=" + str(expired) + "&t=" + str(current) + "&r=" + str(

									 rdm) + "&u=0&f="

									signindex = hmac.new(bytes(secret_key,'utf-8'),bytes(info,'utf-8'), hashlib.sha1).digest() # HMAC-SHA1加密

									sign = base64.b64encode(signindex + bytes(info,'utf-8')) # base64转码，也可以用下面那行转码

									#sign=base64.b64encode(signindex+info.encode('utf-8'))

									url = "http://recognition.image.myqcloud.com/ocr/general"

									headers = {'Host': 'recognition.image.myqcloud.com',

									   "Authorization": sign,

									   }

									files = {'appid': (None,appid),

									 'bucket': (None,bucket),

									 'image': ('1.jpg',open('D:/codes/images/form.jpg','rb'),'image/jpeg')

									 }  

									r = requests.post(url, files=files,headers=headers)

									responseinfo = r.content

									data = responseinfo.decode('utf-8')

									r_index = r'itemstring":"(.*?)"' # 做一个正则匹配

									result = re.findall(r_index, data)

									for i in result:

									 print(i)
