requests.exceptions.ConnectionError #4

Open wacke opened 8 years ago

wacke commented 8 years ago

Hi,

versuche gerade das Python-Beispiel von der Website auszuführen:

import requests
r = requests.get("https://meinsack.click/v1/70327/Ulmer%20Stra%C3%9Fe/")
print("Next: {}".format(r.json().get('dates')[0]))

bekomme als Antwort:

Traceback (most recent call last):
  File "./request.py", line 4, in <module>
    r = requests.get("https://meinsack.click/v1/70327/Ulmer%20Stra%C3%9Fe/")
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/api.py", line 65, in get
    return request('get', url, **kwargs)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/api.py", line 49, in request
    response = session.request(method=method, url=url, **kwargs)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/sessions.py", line 461, in request
    resp = self.send(prep, **send_kwargs)
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/requests/sessions.py", line 573, in send
    r = adapter.send(request, **kwargs)

    raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', error(54, 'Connection reset by peer'))

WHY?!

can not reproduce, can you provide any hints on what you did or when you did it so we can check logs?

Python 2.7.11 (default, Dec 26 2015, 17:47:53)
In [1]: import requests
In [2]: r = requests.get("https://meinsack.click/v1/70327/Ulmer%20Stra%C3%9Fe/")
In [3]: print("Next: {}".format(r.json().get('dates')[0]))

same for python3:

Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
>>> import requests
>>> r = requests.get("https://meinsack.click/v1/70327/Ulmer%20Stra%C3%9Fe/")
>>> print("Next: {}".format(r.json().get('dates')[0]))

maybe the letsencrypt-ssl-certificate is the problem.

r = requests.get("https://meinsack.click/v1/", verify=False)
print(r.json())

Does not help:

PS: same behavior with http w/o "s"

Can reproduce with python 2.7.10 on Mac OS X Yosemite. Interesting...
