I am using a micropython firmware version esp8266-20190125-v1.10.bin for esp8266mod. I accessed REPL prompt via a wired connection using picocom and connected the device to my home wifi. I was trying to send some HTTP post requests using urequests.
import urequests
response = urequests.post('http://lakshmick.pythonanywhere.com/savedata', data = {'string': 'posting from micropython'})
I got some error like this:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "urequests.py", line 115, in post
File "urequests.py", line 100, in request
File "urequests.py", line 79, in request
TypeError: object with buffer protocol required
Does it require any additional configuration procedures before importing urequests?
You need to serialize the data into a string before sending it:
myPostedData = {'YYYY' : 100}
res = urequest.post('https://XXX.amazonaws.com/XXX/XXX', data=json.dumps(myPostedData))
jsonresults = json.loads(res.content)

i have problem with pyinstaller i use library opcua for comunication, with normal run in pycharm everything works correctly, after create .exe with pyinstaller after few second or minute the comunication stops.
from opcua import Client
from opcua.crypto import security_policies

self.client.application_uri = "urn:script:opcua"
# self.client.secure_channel_timeout = 10000
self.client.session_timeout = 60000
self.client.connect()
self.root_node = self.client.get_root_node()
self.call_method('ns=2;s=/Methods/GiveUserAccess', 'OpcUaClient', 'GudWrite')

This is the error after some data exchange:

do you know if there is any modification to make to make it work in pyinstaller for comunication0?
(class with this module is call with a thread)
BadSecurityChecksFailed related to security, are you shure you are destribute the correct certificates? Or if you are using your client on another device, are you matching the correct hostname/ipaddress in the certificates?
I solved. when i created the .exe file with pyinstaller i copied the .der and .pem certificates (all in the same pc) but if i delete them and with python I recreate them automatically, the program works correctly, instead with old certificates, the connection is unstable.
I'm new to pybliometrics. I opened the python pybliometrics documentation and ran this example:
from pybliometrics.scopus import AffiliationSearch
query = "AFFIL(Max Planck Institute for Innovation and Competition Munich)"
s = AffiliationSearch(query)
print(s)
But it throws a pybliometrics.scopus.exception.Scopus401Error error.
Traceback (most recent call last):

As I understand it, I need to specify the API keys. How to do it?
You're right, according to https://pybliometrics.readthedocs.io/en/stable/access.html#error-messages 401 is most likely due to a missing key.
As the documentation on the configuration states, pybliometrics starts a process in the beginning to create the config. It asks for the API keys, and more. It seems you skipped this.
To manually create the config, go to your home directory (~/ on *nix systems) and create the folder .scopus (the dot is important). In there, create the file config.ini with a normal text editor. It needs to have at least those two sections, Directories and Authentication as shown on the documentation on the configuration.
Or simply reinstall pybliometrics and don't skip the set-up prompt in the beginning.
I am trying to copy a workspace to get around the 100 object limit.
Here's my code:
def rg_copy_workspace(workspace_id, new_ws_name, api_token, debug=False):
import smartsheet
smartsheet = smartsheet.Smartsheet(api_token)
smartsheet.errors_as_exceptions(True)
new_workspace = smartsheet.Workspaces.copy_workspace(
workspace_id,
smartsheet.models.ContainerDestination({
'new_name': new_ws_name
})
)
just like the example in the Python SDK.
I am testing on a workspace with a small number of objects (I started with only one Sheet)
I'm getting an error on the folder_obj. I have tried it with and without a folder, and when I have a folder with and without contents.
rg_copy_workspace(workspace_id, new_ws_name)
Traceback (most recent call last):

native = res.native(expected)

What am I doing wrong? I don't know how the code makes it to line 80 of workspaces.py.
I updated to latest version of SDK this morning (after receiving the error)

Reputation won't let me comment.
Your code seemed to execute fine for me on the updated 1.3 SDK.
The traceback locations look to lineup with sources from roughly a year ago, but linecache is pulling from the new source to build the traceback (smartsheet.py, line 210 is actually in a comment, so it's definitely not right). I'm not sure what all the situations are that could account for this but I'd guess there are compiled bytecode (.pyc) files somewhere that are stale.
Can you share a DEBUG level log near the relevant failure so that I can see what the API request looks like?
I've run the following code for over a year and it suddenly stopped working. It has worked until 5/19/2016, and it started failing on 5/31/2016.
import soundcloud
client = soundcloud.Client(access_token=params['token'])
track_uri = client.get('/tracks/' + str(track_id)).uri # This works
client.put(track_uri, track=track) # This fails
It gives me the following traceback:
Traceback (most recent call last):
File "./tools/upload_track.py", line 56, in <module>
client.put(track_uri, track=track)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/soundcloud/client.py", line 133, in _request
return wrapped_resource(make_request(method, url, kwargs))
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/soundcloud/request.py", line 148, in make_request

raise HTTPError(http_error_msg, response=self)
requests.exceptions.HTTPError: 401 Client Error: Unauthorized for url: https://api.soundcloud.com/tracks/266983865
It turns out that despite the error my track is uploaded to Soundcloud anyway. Unfortunately I can't ignore the error because in some cases I post new tracks (client.post instead of client.put), and I need to know the track_id's in order to put them into a playlist.
Some of the things I've tried, where I got the same error:
I tried uploading to a different Soundcloud account
I tried creating the client object with client_id, client_secret, username, and password instead of access_token
I double checked that the token is valid, that it's different every time I run the code, and that the client.get call fails when I use the wrong token
Continuing my search for an answer to get oauth2.0 to work on pythonanywhere.
i am following this tutorial: http://ianalexandr.com/blog/building-a-true-oauth-20-api-with-django-and-tasty-pie.html
im using django 1.6 : https://www.pythonanywhere.com/wiki/VirtualEnvForNewerDjango
when i get to this line of codes:
from provider.oauth2.models import Client
# from django.contrib.auth.models import User
from django.contrib.auth import get_user_model
User = get_user_model()
u = User.objects.get(id=1)
c = Client(user=u, name="mysite client", client_type=1, url="http://pythonx00x.pythonanywhere.com")
c.save()
c.client_id
'd63f53a7a6cceba04db5'
c.client_secret
'afe899288b9ac4127d57f2f12ac5a49d839364dc'
it seems that i got an error at line:
User = get_user_model()
and it raise an error:
raise AppRegistryNotReady("Models aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
here is the full stack trace:
Traceback (most recent call last):
File "addClient.py", line 9, in <module>
User = get_user_model()
File "/home/python2006/.virtualenvs/django16/local/lib/python2.7/site-packages/django/contrib/auth/__init__.py", line 136, in get_user_model

raise AppRegistryNotReady("Models aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
I can't seem to find out how to get the models load.
if I'm getting the idea right.
I think you may not be using the version of Django that you think you are. AppRegistryNotReady was introduced in Django 1.7. I would guess that, if you pinned your DJango version to 1.6, your code would work.
