购买了阿里云的身份证识别OCR：[https://market.aliyun.com/products/57124001/cmapi028587.html\#sku=yuncode2258700001][https_market.aliyun.com_products_57124001_cmapi028587.html_sku_yuncode2258700001]

示例用的是python2，花了点时间给它转成了python3版，并采用了requests库（需要pip install requests）

#!/usr/bin/env python3

        data = {"imgbase64": b64encode(Path(fname).read_bytes()).decode()}
        headers = {
            "Authorization": f"APPCODE {appcode}",
            "Content-Type": "application/json; charset=UTF-8",
        }
        requests.packages.urllib3.disable_warnings()
        r = requests.post(url, json=data, headers=headers, verify=False)
        r.raise_for_status()
        return r.json()
    
    
    def main():
        url = HOST + PATH

        result = verify(url, appcode, fname)
        print(f"Response from ``{url}`` for ``{fname}``:\n{result}")
