我使用API的思科CMX設備ssl.SSLError:警惕的TLSv1協議版本
,並努力寫出Python代碼,這使得GET請求的API信息。代碼如下,除了必要的信息已更改外,其餘與文件中的代碼相同。
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()
不過,我不斷收到以下錯誤:

我也嘗試更新的OpenSSL但沒有任何效果。
請參閱https://github.com/CiscoDevNet/devnet-express-dna-issues/issues/16。看起來你正在Python中使用舊版本的OpenSSL。如果您使用的是隨舊版OpenSSL發佈的Mac,則通常會出現這種情況。 –
我在windows上得到wemos微控制器的二進制工具時遇到了這個問題。原因是谷歌帶我的蟒蛇2.7.3(舊)版本的下載頁面我認爲這是最新的...目前2.7.14是最新的,它不再有這個問題了,它的作品「自動」 。 – Feri
