UnificationEngine：无法使用 TLS 或 SSL 通过 Python 发送请求答案

【问题描述】：

我正在尝试使用 Raspberry Pi 3（模型 B）通过 Python 向统一引擎发送请求。禁用 SSL/TLS 验证后，请求正常发生，但我需要让 SSL/TLS 使用它。

以下代码旨在强制会话使用 TLSv1 来向 UnificationEngine 发送 Python 请求：

class ForceTLSV1Adapter(HTTPAdapter):
    def init_poolmanager(self, connection, maxsize, block=False):
        self.poolmanager = PoolManager(num_pools=connection,maxsize=maxsize,block=block,ssl_version=ssl.PROTOCOL_TLSv1)

def proxy_manager_for(self, proxy, **proxy_kwargs):
    proxy_kwargs['ssl_version'] = ssl.PROTOCOL_TLSv1
    return super(ForceTLVS1Adapter, self).proxy_manager_for(proxy, **proxy_kwargs)

----Some Code here----

s = requests.Session()
s.mount('https://apiv2.unificationengine.com', ForceTLSV1Adapter())

----Some Code Here----

但是，我发送请求后会弹出此错误。

我不确定现在是什么问题。

【问题讨论】：

服务器是否支持tlsv1？
