django-oauth2-provider: get the token without sending the client_secret - python

I'm using django-oauth2-provider with rest-framework to provide authentication in my API.
My mobile app is going to connect to my REST API to retrieve some data. No third party apps are going to get involved in the process.
According to this, the grant type required for this use case would be the password grant. Since it's a bad idea to store the secret in the device, I need to access the token without it.
I tried to send a request without the secret:
curl -X POST -d "client_id=MY_CLIENT_ID&grant_type=password&username=user&password=pass" http://localhost:8000/oauth2/access_token/
But the response I get is:
{"error": "invalid_client"}
My question is whether it is possible to do this with django-oauth2-provider, and how to do it.

Set Authorization Grant Type as Resource owner password-based
Put WSGIPassAuthorization On at same place as WSGIScriptAlias

You need to create a client through django admin UI and replace "MY_CLIENT_ID" with the ID.

"Client type" of application should be "public"

Just to combine solutions. This is what worked for me. Follow through on the Getting Started guide. However, on creating the application, provide the following:
Name: A name of your choosing
Client Type: Public
Authorization Grant Type: Resource owner password-based
Then the request should be:
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d "grant_type=password&username=<username>&password=<password>&client_id=<client_id>" http://localhost:8000/o/token/
or, if JSON,
to settings.py add:
OAUTH2_PROVIDER = {
# expect request body Content Type application/json
'OAUTH2_BACKEND_CLASS': 'oauth2_provider.oauth2_backends.JSONOAuthLibCore'
}
curl -X POST \
http://localhost:8000/o/token/ \
-H 'Content-Type: application/json' \
-d '{
"grant_type": "password",
"client_id": "<client_id>",
"username": "<username>",
"password": "<password>"
}'

You should use password grant type. The following curl command works with django-oauth-toolkit. I believe it should work with any other oauth provider as well.
curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'grant_type=password&username=user&password=pass&client_id=client_id' 'http://localhost:8000/o/token/'

How to authorize via token in Python to an API

I´m completly new in Python-programming and I´m trying to get access to a e – scooter rental service and crawl the data oft he scooters. The service provider is Bird and has no official API and is only accessible via an app for Android or iOS. Someone found a way and the requirements for the posts and gets are here documented: https://github.com/ubahnverleih/WoBike/blob/master/Bird.md
My problem is after i authorized myself by the token I can´t create a get-request. The Server says all the time:
{"code":401,"message":"Credentials are required to access this resource"}
This is my code:
import requests
import json
import uuid
target = "https://api-auth.prod.birdapp.com/api/v1/auth/email"
headers = { "User-Agent": "Bird/4.53.0 (co.bird.Ride; build:24; iOS 12.4.1) Alamofire/4.53.0"
,"Platform": "ios",
"App-Version": "4.53.0",
"Content-Type": "application/json",
"Device-Id": str(uuid.uuid4())}
data = {"email": "any#mail.com"}
reply = requests.post(target, data=json.dumps(data), headers=headers)
# at this point u get an email and u need to copy the token in the email
token = {"token":"IGzMtdAkQ3icmSFV0V64yQ"}
url_token = 'https://api-auth.prod.birdapp.com/api/v1/auth/magic-link/use'
# now you are authorized and you can start get-requests
get_headers = {"Authorization" : "IGzMtdAkQ3icmSFV0V64yQ",
"Device-id" : str(uuid.uuid4()),
"App-Version" : "4.41.0",
"Location" : json.dumps({"latitude":37.77249,"longitude":-122.40910,"altitude":500,"accuracy":100,"speed":-1,"heading":-1})}
url_get_birds = "https://api.birdapp.com/bird/nearby?latitude=37.77184&longitude=-122.40910&radius=1000"
print((requests.get(url_get_birds, headers = get_headers)).text)
The last print command gives me the 401 error all the time
I guess i don´t use the token in get_headers as an authorization correct…
Sorry to bother you but I really don´t know how to progress.
Thank you very much
I don't think you're using the correct token. It appears to me that you are using the Magic Link token as your Auth for getting scooter locations. The Magic Link token that is included in your Email can't be used as the token to get locations of scooters, it's used as the token to get hold of your Access Token. The correct token should start with something like ey and a long list of characters.
Try run this to get your actual token:
curl --location --request POST 'https://api-auth.prod.birdapp.com/api/v1/auth/magic-link/use' \
--header 'User-Agent: Bird/4.53.0 (co.bird.Ride; build:24; iOS 12.4.1) Alamofire/4.53.0' \
--header 'Device-Id: <YOUR-UUID>' \
--header 'Platform: ios' \
--header 'App-Version: 4.53.0' \
--header 'Content-Type: application/json' \
--header 'Content-Type: text/plain' \
--data-raw '{"token":"9BntNB548R7KyD42ml4hrJA"}'
This will output 2 kinds of tokens - Access and Refresh. The Access Token is the one that you would use to get locations of scooters. It should be implemented like this: Authorization: Bird <ACCESS-TOKEN>

Django DRF JWT authentication get token - JSON parse error - Expecting value

I have simple Django DRF application setup which I have implemented JWT authentication.
I used the Django REST framework JWT documentation
I am using curl to test the implementation.
I can successfully get a token using the following notation used in the documentation:
$ curl -X POST -d "username=admin&password=password123" http://localhost:8000/api-token-auth/
The token is returned in following format:
{"token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InNpdHJ1Y3AiLCJleHAiOjE1MTE2NTEyMTQsInVzZXJfaWQiOjEsImVtYWlsIjoiY3VydGlzLnBva3JhbnRAZ21haWwuY29tIn0.F1TSkxe5tQVpddetUdOJDdAPP1XB9Bimb5U3c75oWd0"}
However, when I try using this other variation, I get an error:
$ curl -X POST -H "Content-Type: application/json" -d '{"username":"admin","password":"password123"}' http://localhost:8000/api-token-auth/
The error I get is:
{"detail":"JSON parse error - Expecting value: line 1 column 1 (char 0)"}
I also had the same error when trying to refresh or verify the token:
Refresh:
$ curl -X POST -H "Content-Type: application/json" -d '{"token":"<EXISTING_TOKEN>"}' http://localhost:8000/api-token-refresh/
Verify:
$ curl -X POST -H "Content-Type: application/json" -d '{"token":"<EXISTING_TOKEN>"}' http://localhost:8000/api-token-verify/
I was adding the token as follows:
curl -X POST -H "Content-Type: application/json" -d '{"token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6InNpdHJ1Y3AiLCJleHAiOjE1MTE2NDg5MjIsInVzZXJfaWQiOjEsImVtYWlsIjoiY3VydGlzLnBva3JhbnRAZ21haWwuY29tIn0.T5h_PSvzvKOZCPTS60x5IUm3DgAsRCRmbMJeGWZk3Tw"}' http://localhost:8800/api-token-refresh/
Am I perhaps adding the token incorrectly? Does it need some other formatting with quotes?
Those requests are sending data in two different ways. The first request sends it as form data (x-www-form-urlencoded) which is what your endpoint is expecting and the second request sends it as application/json.
I'm not sure that the library you're using will handle a json request out of the box so one option would be to create a custom endpoint and use something like the following:
import json
def ParseFormData(self, request):
payload = json.loads(request.body.decode('utf-8'))
// use django auth to authorize request and return token
You can read more about it in this answer here: https://stackoverflow.com/a/29514222/5443056
There's instructions for manually creating auth tokens in your library's documentation. Here's the code:
from rest_framework_jwt.settings import api_settings
jwt_payload_handler = api_settings.JWT_PAYLOAD_HANDLER
jwt_encode_handler = api_settings.JWT_ENCODE_HANDLER
payload = jwt_payload_handler(user)
token = jwt_encode_handler(payload)
i suggest use json.dumps({key:value})

AFNetworking and Token from Django JWT

I have used AFNetworking and I have connected to Django api before.
Now problem is I am trying about token authentication in Django.
http://getblimp.github.io/django-rest-framework-jwt/
I have tried these in terminal and it is okay.
$ curl -X POST -d "username=admin&password=abc123" http://localhost:8000/api-token-auth/
$ curl -H "Authorization: JWT <your_token>" http://localhost:8000/protected-url/
I can now get token from AFNetworking too. How can I assign that token in my AFNetworking? I am not quite familiar with curl and AFNetworking.
I tried like this in AFNetworking and it is not okay.
self.manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:[NSURL URLWithString:SERVER_PREFIX]];
NSMutableURLRequest *request = [self.manager.requestSerializer requestWithMethod:method URLString:urlStr parameters:parameters error:&error];
[request setValue:#"Authorization: JWT" forHTTPHeaderField:token];
How shall I do?
I got it now. Based on curl command, I need to write like this.
NSString *token = [[NSUserDefaults standardUserDefaults] objectForKey:#"token"];
if (token) {
token = [NSString stringWithFormat:#"%# %#", #"JWT", token];
[self.manager.requestSerializer setValue:token forHTTPHeaderField:#"Authorization"];
}

Django JWT Auth, why one request works and the other not

I was trying Django JWT Auth and noticed that the URL responds well to one type of post but doesn't respond well to another, but i can figure out why.
Basically, if i use the cURL POST referred in the readme.md, everything goes accordingly to planned:
$ curl -X POST -H "Content-Type: application/json" -d '{"username":"admin","password":"abc123"}' http://localhost:8000/api-token-auth/
but if you i use another type of cURL POST with the same info, it doesn't work:
$ curl -d 'username=admin&password=abc123' http://localhost:8000/api-token-auth/
I know that the "Content-Type" is diferent, but shouldn't the request be accepted in the same manner, they are both well formed posts?
Curl's -d option actually sends the request like it's a web browser. My guess is that the URL you're testing against doesn't have a standard web form, so it can't actually process the request.
TL;DR Pretty sure Django JWT Auth doesn't support the application/x-www-form-urlencoded content type.
From curl manual:
-d --data
(HTTP) Sends the specified data in a POST request to the HTTP
server, in the same way that a browser does when a user has
filled in an HTML form and presses the submit button. This will
cause curl to pass the data to the server using the content-type
application/x-www-form-urlencoded. Compare to -F, --form.
Hope this helps!

"CSRF token missing" when using curl with a Flask app

I am trying to submit a form on a Flask app using curl. Unfortunately, I keep running into the "CSRF token missing" error.
I tried:
curl -X POST --form csrf_token=token --form data=#file.txt --form submit=submit {url} -v
I used a csrf_token from the app while I had it open in a browser. I also looked at https://flask-wtf.readthedocs.org/en/latest/csrf.html and tried to set X-CSRFToken in the header but still got the same error. Any suggestions for what is the correct way to use curl to feed the token to the flask app?
The problem is that you just sending token and flask cannot get your session which lives in browser cookie. So if you wish to access your view via curl it's not enough to pass token value within POST request, you have to attach cookie to. You can write cookie to local file with command:
curl -c /path/to/cookiefile {url}
Then modify it and send POST request to your server with attached cookie and token:
curl -b /path/to/cookiefile -X POST --form csrf_token=token --form data=#file.txt --form submit=submit {url} -v
