1、首先打开，输入百度账号登陆

2、找到文字识别，然后进入后点击创建应用

如下图已经申请到API key和Secret Key

API列表，提供给我们许多免费请求地址

参数为图片的案例:

def getVertifyCode(image):    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('图片地址', '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')if __name__=="__main__":    images = os.listdir("E:/pic/")    for image_name in images:        image="E:/pic/%s" % image_name        getVertifyCode(image)

最后还可以通过百度提供的baidu-aip库进行识别：

from aip import AipOcrimport os"""你的百度AppID, API Key, Secret Key"""APP_ID = '16545975'API_KEY = 'qbK2kKKtrXTo0rE1rg4M6Tl6'SECRET_KEY = 'xxxxxxxxxxx'client = AipOcr(APP_ID, API_KEY, SECRET_KEY)"""打开文件，读取图片"""def get_file_content(filePath):    with open(filePath, 'rb') as fp:        return fp.read()PROJECT_ROOT = os.path.dirname(os.path.realpath(__file__))#获取项目根目录path = os.path.join(PROJECT_ROOT,"images") #文件路径for r, ds, fs in os.walk(path):     for fn in fs:        fname = os.path.join(r, fn)        image = get_file_content(fname)        ret = client.basicGeneral(image)        for item in ret['words_result']:            print(item['words'])
