借助于AI工具来实现验证码识别，内含python3示例

验证码识别的场景十分常见
本文主要讨论作为普通开发者（缺乏/没有Ai学术（教育/实践）背景）的前提下，来低成本快速实现验证码识别

①　2000多本Python电子书（主流和经典的书籍应该都有了）

②　Python标准库资料（最全中文版）

③　项目源码（四五十个有趣且经典的练手项目及源码）

④　Python基础入门、爬虫、web开发、大数据分析方面的视频（适合小白学习）

⑤ Python学习路线图（告别不入流的学习）

本次测试的验证码主要有两种
1. 无干扰的纯数字验证码

2. 有干扰的数字加字母验证码

1. 百度AI大脑

下边我用python3来示例在

这里新建应用

记录appid, apikey, secret key

 复制代码 隐藏代码import requests import base64import shortuuidfrom pprint import pprint#填上自己的app 信息appid = ""key = ""secret = ""def Token():    host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id={}&client_secret={}'.format(key, secret)    response = requests.get(host)    # if response:        # pprint(response.json())    return response.json()['access_token']token =  Token()request_url = "https://aip.baidubce.com/rest/2.0/ocr/v1/general_basic"f = open('./code/code.png', 'rb')img = base64.b64encode(f.read())params = {"image":img,"language_type":"CHN_ENG"}# access_token = '[调用鉴权接口获取的token]'request_url = request_url + "?access_token=" + tokenheaders = {'content-type': 'application/x-www-form-urlencoded'}response = requests.post(request_url, data=params, headers=headers)pprint (response.json())
