I'm building a little application in Python. I use PySide for the GUI and Django to read data from my web application.
Everything works well, but I have a login access, like dropbox application.
I want to store this informations on the current machine (like a session, I don't want to login every time I open the application).
Now my question is, what is the safest way to do this? Environment variables?
Usually when you have an API that you're exposing in your app to the outer world (even your own desktop/mobile app), you'll design this API to be stateless, as part of the REST architecture. So your app should always include an HTTP header or any other method of carrying an authentication token that will let your API identify the user.
You only log in once, and when the log-in procedure is successful you should get an authentication token from your API, and then you will store this token somewhere safe.
You can also look into implementing OAuth2 for the authentication.

I was using Flask for a small personal project of mine, and using render template and simple HTML files for the front-end.
I recently decided to switch over to a react front-end with a REST API in Flask.
However, since a lot of my old flask code depended on using sessions within Flask, I was wondering if sessions can still be used with a REST API.
There are essentially two parts to the question:
Is it technically correct (i.e. would it even work)
Is it advisable (If no, why not)
Thanks
Yes you can use sessions for login for a front end API. For backend APIs I suppose you could as well but something like jwt or oauth2 is much more common for a few convenience reasons. Not sure the set cookie header works when called via the JS fetch api so you may need to create your own session cookie with JS and possibly in middleware. You also have the option of having the login page not part of the API which would solve this problem.
Other than that as long as the session cookie is being passed to the API every time it is called which should happen automatically you will be able to use sessions in your Flask code.
I have recently started learning Python. I am currently trying to build a simple Web Application that requires a login to access some paths.
I understand that this can be achieved by using something like session['user']=user_id in Flask.
Can somebody help me with how exactly this works? Like where does Flask store the sessions if not in the database table?
It stores it in a cookie on the client side. From the official documentation:
This is implemented on top of cookies for you and signs the cookies cryptographically. What this means is that the user could look at the contents of your cookie but not modify it, unless they know the secret key used for signing.
If you need server-side session store, there is an extension called Flask-Sessionstore that lets you choose the method of storage, including server-side DBs.
I am currently learning how to use django. I have a standalone python script that I want to communicate with my django app. However, I have no clue how to go about doing this. My django app has a login function and a database with usernames and passwords. I want my python script to talk to my app and verify the persons user name and password and also get some account info like the person's name. How do I go about doing this? I am very new to web apps and I am not really sure where to begin.
Some Clarifications: My standalone python program is so that the user can access some information about their account. I am not trying to use the script for login functionality. My django app already handles this. I am just trying to find a way to verify that they have said account.
For example: If you have a flashcards web app and you want the user to have a program locally on their computer to access their flashcards, they need to login and download the cards from the web app. So wouldn't the standalone program need to communicate with the app to get login information and access to the cards on that account somehow? That's what I am trying to accomplish.
If I understand you correctly, you're looking to have an external program communicate with your server. To do this, the server needs to expose an API (Application Interface) that communicates with the external program. That interface will receive a message and return a response.
The request will need to have two things:
identifying information for the user - usually a secret key - so that other people can't access the user's data.
a query of some sort indicating what kind of information to return.
The server will get the request, validate the user's secret key, process the query, and return the result.
It's pretty easy to do in Django. Set up a url like /api/cards and a view. Have the view process the request and return the response. Often, these days, these back and forth messages are encoded in JSON - an easy way to encapsulate and send data. Google around with the terms django, api, and json and you'll find a lot of what you need.
I want to use Google API to track the number of tweets a particular website (say Rbloggers) make each day. And I am trying to do it in Python.
I am completely new to this. So, I was looking at the hello-analytics-api, in which I need to deal with OAuth 2.0. And I have no idea what to put down for the redirect URI.
I have read
What's a redirect URI? how does it apply to iOS app for OAuth2.0?
But I still don't quite understand the concepts and what I should put down for the 'redirect URI' ?
From Choosing a redirect URI
When you create a client ID in the Google Developers Console, two redirect_uris are created for you: urn:ietf:wg:oauth:2.0:oob and http://localhost. The value your application uses determines how the authorization code is returned to your application.
In case of desktop apps or programs, you should set it to urn:ietf:wg:oauth:2.0:oob so that you will be redirected to the page where you can copy the authorization code from internet browser and paste it in your desktop app
I am trying to create some Glassware with the Mirror API. I am new to using AppEngine and Jinja2. I have python experience but never with a web framework before. So basically I am very new at this.
I have modified the Python quickstart for the mirror API to include many of my endpoints and designs. Basically I want to be able to be able to POST data from a constrained device to Glass. I have an endpoint all setup which works to accept and parse out the data and send the timeline item.
My problem is that the device itself is acting all on it's own and cannot provide input, therefore when I call my app from it e.g. https://foo.appspot.com?operation=deviceData the app presents the auth page and then nothing happens. I can see in the logs that the auth page is being sent, but the device has no idea what to do with this.
Basically, I need a way where I can hardcode credentials and get around having to do oauth everytime. What is the recommended way to do this? Another app which doesn't require auth which passes the data along? This would be fine as I only need to set this up with one user right now, it is for an internal demo only.
Is it possible to set my credentials in a header and auth automatically without handling any return, more like how basic auth works?
There are also the "Simple API access" keys. Would these work in this situation, I tried creating browser and server keys and tried them on the device and in the browser by doinghttps://foo.appspot.com?operation=deviceData&key=KEY_HERE but in both cases I was still prompted to login. Is this what simple access keys are for? Do they not work with the mirror API?
Basically my question is, what's the easiest way to allow access to my apps endpoints without having to oAuth or having a hard coded user which auto-auths?
