zeep requests.exceptions.SSLError: ("握手错误: 错误([('SSL 例程', 'ssl3_get_server_certificate', '证书验证失败')],)",)

Question

我尝试在 python 的 zeep lib 的帮助下创建 SOAP 客户端

import os
from zeep import Client
from zeep.wsse.signature import Signature

key_filename = "/etc/ssl/certs/cert.key.pem"
cert_filename = "/etc/ssl/certs/cert.crt.pem"

client = Client('https://37.230.149.6:10004/emias-soap-service/PGUServicesInfo2?wsdl', wsse=Signature(key_filename, cert_filename))

但有一个例外：

Traceback (most recent call last):

    wsse=Signature(key_filename, cert_filename))

    raise SSLError(e, request=request)
requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",)

如何修复此异常以及我的代码有什么问题？

Answer 1

显式地将

Session

对象传递给您的 zeep

Client

（通过

Transport

对象）并设置

verify=False

这是一个例子：

from requests import Session
from zeep import Client
from zeep.transports import Transport
from zeep.wsse.signature import Signature

import os

key_filename = "/etc/ssl/certs/cert.key.pem"
cert_filename = "/etc/ssl/certs/cert.crt.pem"

session = Session()
session.verify = False

client = Client(
    'https://37.230.149.6:10004/emias-soap-service/PGUServicesInfo2?wsdl',
    wsse=Signature(key_filename, cert_filename),
    transport=Transport(session=session)
)

或者，您应该这样做的方法是将

session.verify

设置为 CA 颁发机构证书（安装在服务器 ROOT 和 SUB 证书上的证书的颁发者），例如：

session.verify = "/path/to/ca_cert.pem"

如果证书的颁发者与

ca_cert.pem

中的颁发者相同，这基本上会告诉你的Python脚本信任该URL

Answer 2

这对我有用-

session.verify = False

Answer 3

我认为你需要使用 verify=False

Answer 4

client = Client(wsdl=wsdl_url)
client.transport.session.verify = False
