我在使用 python 的请求包向 Puppet 3.7 的 REST API 提交 GET 请求时遇到问题。我在这里查看了此文档：
http://docs.python-requests.org/en/latest/user/advanced/#ssl-cert-verification
但我仍然有麻烦。这是我的脚本：
[root@ppt-001 RESTClients]# cat add-group.py
#!/usr/bin/env python
import requests
# curl https://ppt-001.example.com:4433/classifier-api/v1/groups \
# -H "Content-Type: application/json" \
# --cert /etc/puppetlabs/puppet/ssl/certs/ppt-001.example.com.pem \
# --key /etc/puppetlabs/puppet/ssl/private_keys/ppt-001.example.com.pem \
# --cacert /etc/puppetlabs/puppet/ssl/certs/ca.pem | python -m json.tool
url='https://ppt-001.example.com:4433/classifier-api/v1/groups'
headers = {"Content-Type": "application/json"}
data={}
cacert='/etc/puppetlabs/puppet/ssl/certs/ca.pem'
key='/etc/puppetlabs/puppet/ssl/private_keys/ppt-001.example.com.pem'
cert='/etc/puppetlabs/puppet/ssl/certs/ppt-001.example.com.pem'
result = requests.get(url,
data=data, #no data needed for this request
headers=headers, #dict {"Content-Type":"application/json"}
cert=(cacert,key), #key/cert pair
verify=cert
)
print result.json()
我正在使用这个版本的python：
[root@ppt-001 RESTClients]# python -V
Python 2.7.5
这是我执行脚本时发生的情况：
[root@ppt-001 RESTClients]# ./add-group.py
/usr/lib/python2.7/site-packages/requests-2.7.0-py2.7.egg/requests/packages/urllib3/util/ssl_.py:90: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.

[root@ppt-001 RESTClients]#
我怀疑它requests不喜欢 Puppet 使用的自签名证书，但是如果我发出这个curl命令......
curl https://ppt-001.example.com:4433/classifier-api/v1/groups \
-H "Content-Type: application/json" \
--cert /etc/puppetlabs/puppet/ssl/certs/ppt-001.example.com.pem \
--key /etc/puppetlabs/puppet/ssl/private_keys/ppt-001.example.com.pem \
--cacert /etc/puppetlabs/puppet/ssl/certs/ca.pem | python -m json.tool
...一切正常。
更新：
我已经安装requests[security]：
[root@ppt-001 RESTClients]# pip install requests[security]

Cleaning up...
但是现在当我运行我的脚本时，我得到了这个 putput：
[root@ppt-001 RESTClients]# ./add-group.py
