I'm trying to connect to JIRA using a Python wrapper for the Rest interface and I can't get it to work at all. I've read everything I could find so this is my last resort.
I've tried a lot of stuff including
verify=False
but nothing has worked so far.
The strange thing is that with urllib.request it does work without any SSL cert (it's just some internal cert) but the goal is to use the Python Jira wrapper so it's not really an option...
I've tried Python 3.4 and 2.7... getting desperate...
Any ideas?
The code is very simple:
import requests
r = requests.get('https://jiratest.myurl.com/rest/api/2/serverInfo')
print(r.content)

There is a problem with our infrastructure which seems to bring out a bug in the requests module where the SSL verification ignore flag doesn't work properly.
None of the solutions offered in any of the Stackoverflow posts worked.
As a workaround I'm running the code directly on the server.
If you have certificate file(Certificate.pem) and key file(Key.pem) then we can authenticate like this
cert=/path/to/certificate_file
key_file=/path/to/key_file
url=https://jiratest.myurl.com/rest/api/2/serverInfo
with requests.session() as session:
session.cert=(cert,key_file)
session.auth=(username,base64.urlsafe_b64decode(password))
response=session.get(url)
if response.status_code == 200:
json_data = response.json()

I'm trying to onboard a simple python model from CLI as shown in the related tutorial.
After providing the onboarding token (user:api-token) I'm getting the error below.
The Acumos platform has been deployed using the AIO tools using prep-deploy process.
I was able to dump the same model and onboard using the web UI.

UPDATE
I've solved by adding the following line into the python script:
os.environ['CURL_CA_BUNDLE'] = ""
In addition to that I also had to change the push url ("acumos/onboarding-app/v2/models") as it was wrongly reported in the acumos python client library ("acumos/onboarding-app/v2/push").
I recomend you to add the following in your python script
os.environ['CURL_CA_BUNDLE'] = ""
it will skip the certificate verification
I installed yfinance in Spyder (Python 3.7) but when I make a basic call, such as:

progress=False)
print(df_yahoo)

I believe the problem comes from an external source, maybe Yahoo Finance was down? I tried running your code and it works fine for me. (PyCharm, Python 3.7)
On MacOS Big Sur, You need to install the certificate in Python 3.9.
cd /Applications/Python\ 3.9/
./Install\ Certificates.command
I use Shadowsocks to get out from the Chinese GFW. It works fine when I use chrome to browse www.google.com.
Recently I am learning something about python crawlers, and I want to fetch data from www.google.com by using request.
I learned that I have to set proxy to get out from the GFW, and the code is like
import socket
import socks
import requests
socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 1080)
socket.socket = socks.socksocket
print(requests.get('http://ifconfig.me/ip').text)
and then I get the address of my Shadowsocks server
/Library/Frameworks/Python.framework/Versions/3.5/bin/python3.5 /Users/lsongseven/PycharmProjects/wordcloud/cl.py
52.73.41.9
and here is my Shadowsocks configuration
enter image description here
However, when I use this script to fetch data from google, it doesn't work anymore
import socket
import socks
import requests
socks.set_default_proxy(socks.SOCKS5, "127.0.0.1", 1080)
socket.socket = socks.socksocket
print(requests.get('https://www.google.com/').text)

So the problem is that Shadowsocks works fine but the python script cannot work, does anyone have some suggestions?
"SSLEOFError" Seems like OpenSSL cause this prolbem.
You may try to upgrade your OpenSSL viesion,or reinstall OpenSSl.

Here is script I tried.
import requests
url = "https://klevas.vu.lt/"
page = requests.get(url, verify=False)
print (page.content)
Changing url to https://www.klevas.vu.lt (added www) results in different error: class 'socket.gaierror'>: [Errno 11004]

Example to what #sigmavirus24 meant:
(It's taken literally from the the linked blog post, only PROTOCOL_SSLv3 is used
import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.poolmanager import PoolManager
import ssl
class MyAdapter(HTTPAdapter):
def init_poolmanager(self, connections, maxsize, block=False):
self.poolmanager = PoolManager(num_pools=connections,
maxsize=maxsize,
block=block,
ssl_version=ssl.PROTOCOL_SSLv3)
s = requests.Session()
s.mount('https://', MyAdapter())
print(s.get('https://klevas.vu.lt/'))
The server you are talking to is an application server from oracle. When searching for it's server identificator you get links to a lot of bugtrackers of open source projects running into this bug -.-
This seems to be an issue with openssl which is what Python's ssl module relies on (and which in turn requests relies on). The way to verify this is by using the openssl s_client command to check this:
~/sandbox/requests (master) openssl s_client -connect klevas.vu.lt:443
CONNECTED(00000003)
140721982121664:error:140773E8:SSL routines:SSL23_GET_SERVER_HELLO:reason(1000):s23_clnt.c:741:
---
no peer certificate available
---
No client certificate CA names sent
---
SSL handshake has read 7 bytes and written 319 bytes
---
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
---
That's the same error I see when testing this on python 2.7.
Furthermore, if I test the second url www.kleavs.vu.lt I get this:
~/sandbox/requests (master) openssl s_client -connect www.klevas.vu.lt:443
connect: Connection refused
connect:errno=111
Which is the same thing I see when I try to request the second URL via requests on either Python 2 or 3.
This is not an issue with requests but similar bugs have been filed: #606 (which is where I pulled the openssl command).
You can attempt to follow the instructions here to determine if a different version of TLS or SSL will fix this for you, but I'm not sure it will help in this case.
The solution from t-8ch misses the promised link.
This solution need extra modules which were neither described nor linked.
I found that at least with Xubuntu 14.04 you need to install these modules to get the code running:
a. python3-requests (http://github.com/kennethreitz/requests)
b. python3-urllib3 (http://urllib3.readthedocs.org/en/latest)
Then I needed to modify the code a little bit:
from urllib3.poolmanager import PoolManager
rather than
from requests.packages.urllib3.poolmanager import PoolManager
import requests
from requests.adapters import HTTPAdapter
from urllib3.poolmanager import PoolManager
import ssl
class MyAdapter(HTTPAdapter):
def init_poolmanager(self, connections, maxsize, block=False):
self.poolmanager = PoolManager(num_pools=connections,
maxsize=maxsize,
block=block,
ssl_version=ssl.PROTOCOL_SSLv3)
s = requests.Session()
s.mount('https://', MyAdapter())
print(s.get('https://klevas.vu.lt/'))
returns
