ssl.SSLError：tlsv1警报协议版本

Question

我将REST API用于Cisco CMX设备，并尝试编写Python代码，该代码向该API发出GET请求。代码如下，除了更改了必要的信息外，与文件中的代码相同。

from http.client import HTTPSConnection

from base64 import b64encode

# Create HTTPS connection

c = HTTPSConnection("0.0.0.0")

# encode as Base64

# decode to ascii (python3 stores as byte string, need to pass as ascii 

value for auth)

username_password = b64encode(b"admin:password").decode("ascii")

headers = {'Authorization': 'Basic {0}'.format(username_password)}

# connect and ask for resource

c.request('GET', '/api/config/v1/aaa/users', headers=headers)

# response

res = c.getresponse()

data = res.read()

但是，我不断收到以下错误：

Traceback (most recent call last):

  File "/Users/finaris/PycharmProjects/test/test/test.py", line 14, in <module>

    c.request('GET', '/api/config/v1/aaa/users', headers=headers)

我也尝试更新OpenSSL，但这没有效果。

我遇到了同样的错误，谷歌将我带到了这个问题，所以这就是我所做的，希望它可以帮助处于类似情况的其他人。这适用于OSX。在终端中检查我拥有哪个版本的OpenSSL：$ python3 -c "import ssl; print(ssl.OPENSSL_VERSION)">> OpenSSL 0.9.8zh 14 Jan 2016由于我的OpenSSL版本太旧，无法接受答案。因此，我不得不更新OpenSSL。要做到这一点，我更新的Python到最新版本（从3.5版到3.6版）与自制，以下一些建议的步骤在这里：$ brew update$ brew install openssl$ brew install python3然后我在使用PATH和所使用的python版本时遇到了问题，因此我刚刚创建了一个新virtualenv版本，以确保采用了最新版本的python：$ virtualenv webapp --python=python3.6问题已解决。
