带有SSL中的简单发布请求的线程中的SSL错误

Question

I'm trying to do a simple post request, I'm using a list because I want to send all my post request at the same time using thread. Here is an example of an url :

            s = "https://emoncms.org/input/post.json?node="+str(test)+"&json={test_stack_overflow:0}&apikey="+str(apikey)
            list.append(threading.Thread(target=requests.post, args=([s, ])))

I was using this code maybe 3 months ago and it worked perfectly. I wanted to get back on this project this week and I realized that I got some errors, this one particularly :

Exception in thread Thread-14:

Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
  self.run()
File "/usr/lib/python2.7/threading.py", line 763, in run
  self.__target(*self.__args, **self.__kwargs)
File "/usr/lib/python2.7/dist-packages/requests/api.py", line 94, in post
  return request('post', url, data=data, json=json, **kwargs)
File "/usr/lib/python2.7/dist-packages/requests/api.py", line 49, in request
  return session.request(method=method, url=url, **kwargs)
File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 457, in request
  resp = self.send(prep, **send_kwargs)
File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 569, in send
  r = adapter.send(request, **kwargs)
File "/usr/lib/python2.7/dist-packages/requests/adapters.py", line 420, in send
  raise SSLError(e, request=request)
SSLError: <unprintable SSLError object>

I got an other error, ConnectionError but I think it's due to the network or because the website can't follow it's activity or is down. I leave you the traceback if you want :

ConnectionError: ('Connection aborted.', error(101, 'Network is unreachable'))

This code is only a part of my project, the code is running every minutes and I don't know why but this issue (SSLError) comes only maybe 10 times a day. I got this script running on different Raspberry Pi and some have the same problem but not the same frequency, others don't have it at all.

Any ideas on what is going ?
Thanks in advance !

Answer 1

Use verify=False in the requests method like this

import requests
url="https://emoncms.org/input/post.json?node="+str(test)+"&json={test_stack_overflow:0}&apikey="+str(apikey)
requests.post(url,verify=False)

If you are using with threads then it will be like

list.append(threading.Thread(target=requests.post, args=(url,),kwargs={"verify":False})) #**kwargs should be passed seperately.

You are getting this error because python requests tries to verify certificate for https connections so you have to override it by passing verify=False or you can also provide certificate in verify like this requests.get(url,verify="/path/to/certificate.ext")

Also I doubt that this should be a get request because query parameters won't come in post request as of my knowledge. So if you use GET method same verify applies there too.
