图片验证码识别：

一、百度OCR文字识别云服务

百度云-产品-搜索：文字识别-通用场景文字识别-立即使用-开通（实名认证）-免费尝鲜-创建新应用-调用服务-通用场景文字识别（高精度版）-复制相关代码

需要终端安装base64:pip install pybase64

import requests
import base64host = 'https://aip.baibubce.com/pauth/2.0/token?grant_type=client_credentials&client_id=[官网获取的AK]&client_secret=[官网获取的SK]'
response = requests.get(host)
if response:access_token = reponse.json()["access_token"]print(access_token)request_url = "https://aip.baidubce.com/rest/2.0/ocr/v1/accurate_basic"
# 二进制方式打开图片文件
f = open('[本地文件]', 'rb')
img = base64.b64encode(f.read())params = {"image":img}
# access_token = '[调用鉴权接口获取的token]'
request_url = request_url + "?access_token=" +access_token
headers = {'content-type': 'application/x-www-form-urlencoded'}
response = requests.post(request_url, data=params, headers=headers)
if response:print(response.json()["words_result"][0]["words"])
