使用SSLv3向HTTPS服务器发送Python REST请求

我试图从URL检索数据，但由于以下错误，我的连接被阻止：

requests.exceptions.SSLError: HTTPSConnectionPool(host='securehost', port=4443): Max retries exceeded with url: secureURL (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_read_bytes', 'sslv3 alert handshake failure')],)",),))

到目前为止，我认为我收到了这个错误，因为他们无法就使用SSL密码达成一致

请求库中的默认SSL类型为：

TLS13-AES-256-GCM-SHA384:TLS13-CHACHA20-POLY1305-SHA256:TLS13-AES-128-GCM-SHA256:ECDH+AESGCM:ECDH+CHACHA20:DH+AESGCM:DH+CHACHA20:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:RSA+AESGCM:RSA+AES:!aNULL:!eNULL:!MD5

但是，当我在服务器上运行curl-v时，我试图从服务器请求数据，结果如下：

$ curl -v SecureLink

我已尝试通过以下方式编辑默认密码：

requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS += ':RC4-SHA'

及

无济于事

非常感谢您通过请求库提供的有关成功连接的任何帮助

到目前为止，我的代码是：

import requests
import json
import ssl
from urllib3.contrib import pyopenssl
import MySQLdb

params = {"t": "8IBYCELFMTKRI08K5T9YUKPN7K21YZQZ0PXV"}


print(requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS)
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS += 'ALL:eNULL'

s = requests.Session()

print(requests.get('secureURL', params=params, timeout=5, verify=False).text)

我正在使用Python 2.7.13。 我安装的软件包是：

ASN1加密0.22.0

certifi 2017.7.27.1

cffi 1.10.0

chardet 3.0.4

密码学2.0.3

第34 1.1.6条

idna 2.6

IP地址1.0.18

pyOpenSSL 17.3.0

pycparser 2.18

请求2.18.4

urllib3 1.22

据我所知，错误是sslv3握手失败

即使我在网络上，我也需要使用VPN连接才能运行脚本。我不确定为什么会出现这种情况，但如果没有VPN连接，它将无法工作。我希望有一天这能帮助别人解决问题。

bumping thread在这一点上确实需要备份。我正在尝试配置ssl套接字

import requests
import json
import ssl
from urllib3.contrib import pyopenssl
import MySQLdb

params = {"t": "8IBYCELFMTKRI08K5T9YUKPN7K21YZQZ0PXV"}


print(requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS)
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS += 'ALL:eNULL'

s = requests.Session()

print(requests.get('secureURL', params=params, timeout=5, verify=False).text)
