尝试从远程服务器备份Firebase时遇到501服务器错误：未实现错误

Question

I have a Python script that pulls backup of the Firebase db and saves it to the server. I am able to execute it successfully from my machine, however, when I run it from pythoneverywhere server, I get the following error:

Traceback (most recent call last):
  File "somescript.py", line 58, in <module>
    data = json.dumps(f.get('/', None), sort_keys = False, indent = 4)
  File "/home/<username>/.local/lib/python2.7/site-packages/firebase/decorators.py", line 19, in wrapped
    return f(*args, **kwargs)
  File "/home/<username>/.local/lib/python2.7/site-packages/firebase/firebase.py", line 274, in get
    return make_get_request(endpoint, params, headers, connection=connection)

    return f(*args, **kwargs)

requests.exceptions.HTTPError: 501 Server Error: Not Implemented

2015-03-17 15:01:12 -- Completed task, took 4.00 seconds, return code was 1.

Here is the relevant part of the script:

def connect_firebase(configs):
    firebaseUrl = configs.get('Firebase', 'ProdFirebaseURL')
    firebaseSecret = configs.get('Firebase', 'FirebaseSecret')

    f = firebase.FirebaseApplication(firebaseUrl, None)
    f.authentication = firebase.FirebaseAuthentication(firebaseSecret, "", admin=True)
    return f

...

f = connect_firebase(config)
data = json.dumps(f.get('/', None), sort_keys = False, indent = 4) #busts here

Same script with same params was running fine on pythoneverywhere server a few weeks ago. I have reinstalled requests 1.1.0 and python-firebase using pip on both my machine and the server and am still able to access it from my machine but not from pythoneverywhere server. Any idea what would cause this?

Answer 1

If you can get past the authentication part, then the connection should be getting through/it isn't a proxy problem.

Maybe double check your ProdFirebaseURL is correct? And double check that the '/' that you are calling f.get() on is a valid end point?

I would try doing f.get(<the-full-url>) just to double check/make sure.

Answer 2

This was fixed by uninstalling requests 1.1.0 lib from the server. Still no idea what was wrong, since Firebase folks advise to install that library prior to installing Firebase .
