Question

OS: Ubuntu 16.04
Python: 2.7
OpenSSL: 1.0.2l

我正在尝试通过python虚拟环境提交SOAP请求，并且我通过不同的包获得SSL错误。到目前为止，我已经尝试过suds和zeep，无论请求方法如何都会产生错误。

# credentials
tuser = args['user']
tpass = args['pass']
url = 'https://soapendpoint.com/services?wsdl'

# in suds
from suds.client import Client
sclient = Client(url, username=tuser, password=tpass)

# in zeep
from zeep import Client
from zeep.wsse.username import UsernameToken
zclient = Client(url, wsse=UsernameToken(tuser,tpass))

运行时，suds代码会产生此错误：

运行时，zeep代码会产生此错误：

    raise SSLError(e, request=request)
requests.exceptions.SSLError: ("bad handshake: SysCallError(-1, 'Unexpected EOF')",)

我尝试使用多种不同的身份验证方法尝试这两种功能，无论我做了什么更改，都会使用相同的错误代码。这是Python之外的更高级错误吗？ suds请求在Ubuntu 14.04上运行的另一台机器上运行正常。

第二个错误的根本原因：

requests.exceptions.SSLError: ("bad handshake: SysCallError(-1, 'Unexpected EOF')",)

...可能是请求库中的this open bug：“ Session.verify =设置了REQUESTS_CA_BUNDLE环境变量时将忽略False”。

我们已经看到类似的问题突然在特定主机上开始。事实证明，env变量是最近在此处设置的，尽管已初始化为False，但它开始导致使用session.verify不是False生成请求。一旦我们删除了REQUESTS_CA_BUNDLE环境变量，错误就会停止。

SSL错误：＆＃39;意外的EOF＆＃39;
