百度 验证码识别API 使用

Posted 2020-11-01

先到百度云申请文字识别API ，会给你一个API KEY和一个SECRET KEY，免费，一天最多500次请求。

 

try:
    temp_url = \'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【API KEY】&client_secret=【SECRET KEY】\'
    temp_res = requests.post(temp_url)
    temp_token = eval(temp_res.text)[\'access_token\']
    temp_url = \'https://aip.baidubce.com/rest/2.0/ocr/v1/general_basic?access_token=\' + temp_token
    temp_headers = {\'Content-Type\': \'application/x-www-form-urlencoded\'}
    temp_file = open(\'code_xjtu.png\', \'rb\')
    temp_image = temp_file.read()
    temp_file.close()
    temp_data = {
        \'image\': base64.b64encode(temp_image)
    }
    temp_data = urllib.parse.urlencode(temp_data)
    temp_res = requests.post(url=temp_url, data=temp_data, headers=temp_headers)
    code = int(eval(temp_res.text)[\'words_result\'][0][\'words\'])
except Exception as e:
    print(e)
    print(\'验证码识别异常，请联系管理员\')
