Falcon python M2Crypto RSA 错误

Question

我们最近开发了一个使用 RSA 的 API，主要问题是在控制台中它可以正常工作，但是一旦进入应用程序的 "venv" 就会显示不同的错误。

Traceback (most recent call last):

    from SocketServer import BaseServer, ForkingMixIn, TCPServer, ThreadingMixIn
ImportError: No module named 'SocketServer'

M2Crypto 库已安装在 ubuntu 和 pip 中。

使用RSA的代码是：

def sella_xml(cfdi, numero_certificado, archivo_cer, archivo_pem):
    keys = RSA.load_key(archivo_pem)
    cert_file = open(archivo_cer, 'r')
    cert = base64.b64encode(cert_file.read())
    xdoc = ET.fromstring(cfdi)
    xsl_root = ET.parse('cadenaoriginal_3_3.xslt')
    xsl = ET.XSLT(xsl_root)
    cadena_original = xsl(xdoc)
    digest = hashlib.new('sha256', str(cadena_original)).digest()
    sello = base64.b64encode(keys.sign(digest, "sha256"))
    comp = xdoc.get('Comprobante')
    xdoc.attrib['Sello'] = sello
    xdoc.attrib['Certificado'] = cert
    return ET.tostring(xdoc)

运行环境的命令：

 /root/merci_api/venv/bin/gunicorn --workers 3 -b localhost:5000 main:app

有什么建议吗？

我做错了什么？

Answer 1

嗯，问题是我们安装的版本上的 M2Crypto 与 Python 3.* 不兼容，所以当我们使用另一个 M2Crypto 版本时，我们还有另一个问题 "SSL v2"解决我们需要这个。

安装Python2.*
直接从存储库安装最新版本的 M2Crypto。
pip uninstall -y m2crypto
pip 安装git+https://gitlab.com/m2crypto/m2crypto.git

除非你使用 python3 分支 M2Crypto 仍然不支持 py3k。
