Falcon M2Crypto RSA错误

Question

我们最近开发了一个使用RSA的API，主要问题是它在控制台中工作正常，但是一旦输入应用程序的"venv“，就会显示出不同的错误。

Traceback (most recent call last):


File "/root/merci_api/venv/lib/python3.5/site-packages/gunicorn/arbiter.py", line 557, in spawn_worker

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

在ubuntu和pip中都安装了M2Crypto库。

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)

Run Env命令：

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

有什么建议吗？

我做错什么了？

Answer 1

问题是，我们安装的版本上的M2Crypto与Python3.*不兼容，所以当我们使用另一个M2Crypto版本时，我们有另一个问题"SSL v2“来解决我们需要解决的问题。

• 安装Python 2.*
• 直接从回购程序中安装最新版本的M2Crypto。
• pip卸载-y m2crypto
• pip安装git+https://gitlab.com/m2crypto/m2crypto.git

除非使用python3分支，否则M2Crypto仍然不支持py3k。
