I'm trying to call Bitbucket API in my python script to retrieve some data.
I use the key/secret pair of Bitbucket OAuth.
data = { 'grant_type': 'client_credentials'}
response = requests.post('https://bitbucket.org/site/oauth2/access_token', data=data, auth=(key, secret))
print(response.json())
access_token = response.json()['access_token']
print(access_token)
groups = requests.get("https://api.bitbucket.org/1.0/groups/myaccount/", headers={"Bearer %s" %access_token})
print(groups.json())
This gives me an error:

How do we use access token to call BitBucket API REST ?

now it's saying

the headers parameter to the requests.get() should be an dictionary and you are sending set instead of the dictionary check your code it is headers={"Bearer %s" %access_token} which treated as set you can execute this on python and check.
You may need to use key:value check below example:
groups = requests.get("https://api.bitbucket.org/1.0/groups/myaccount/", headers={'access_token' : "Bearer %s" %access_token})
I successfuly get to retreive the data from Bitbucket API by passing the access token this way:
groups = requests.get("https://api.bitbucket.org/1.0/groups/myaccount/access_token={%s}"%access_token)
Use Authorization as a key in the header instead of access_token try below code.
groups = requests.get("https://api.bitbucket.org/1.0/groups/myaccount/", headers={'Authorization' : "Bearer %s" %access_token})

Hello I am trying to connect to a neo4j database with py2neo.
This code works so far:
graph = Graph(bolt=True, host='***',
bolt_port=***,
http_port=***,
user='***',
password='***')
But when I protect my IP address with a password over HTTP then I can't connect and I don't know how to authorize py2neo to connect.
Does anyone know how I can solve this? :)
Edit :
When I open the ip in a web browser i need to input a user and a password before i can see the neo4j browser - and I do not now how to input these credentias with py2neo (because it seems that this is my problem)

Whenever I access the panel blueprint I receive this error: peewee.OperationalError: Connection already open
This is how I initialize the database in my main app file.
flask_db = FlaskDB(app)

The problematic code seems to be

client = Client.get(Client.subdomain == values.pop('client'))
The full source code can be found on Gitlab
__init__.py is the main app file. panel/__init__.py has the problematic code. This is the full traceback I receive:

As you can see the database is actually connected, and the client table is available.
Edit 2:
Well, I just found that apparently just database.get_tables() will cause this error. However, that code does fetch all tables from the database...
Does url_value_preprocessor run before the database is initialized? That would be strange since I import the object calling this decorator after initializing the database.
I'm trying to create a small flask application using the Enferno framework, but when I try to register a user I get an error that seems to be generated by the passlib library. I can't understand if it's something I did or if it is an error in the library itself.

I just ran into this. Turns out, I had installed both bcrypt and python-bcrypt in my virtualenv. passlib.hash.bcrypt has a check to see which version on bcrypt is present. By removing the python-bcrypt, I was able to cease this error from being thrown.
So I'm using flask to receive form data, which has worked fine with url-encoded data (application/x-www-form-urlencoded). I can just access the request.form in my routing functions.
However if I try to instead send data using multipart/form-data, I consistently get the error: TypeError: cannot concatenate 'str' and 'NoneType' objects
This error occurs as soon as I try to access the request form, e.g. the line:
f = request.form. So it's nothing to do how I'm actually using the form data. It also happens regardless if I send the data from Fiddler, Postman or my own custom Java app.
Am I missing some code in flask to handle multipart form data, or is the request somehow invalid? Here's an example request from postman that causes the error:
And here's the full traceback (Locus is my app, so only line 18/19 are from my own code):
