Update/provide new method to get device_auths.json

[fatinghenji]

Current Behavior (if any)

1. By using DeviceAuthGenerator.exe to get the file I should get.
2. DeviceAuthGenerator.exe runs with an error.
3. This issue has been raised in DeviceAuthGenerator-issue3, but has never been fixed.

   Desired Behavior

   Get the availabledevice_auths.json file

   Motivation / Use Case for Changing the Behavior

   Normal deployment and use of EpicGames Freebies Claimer

Well, I am trying to adopt a native method, by using the fnbrjs library (check the fnbrjs branch), but I am struggling to implement it properly. I cannot figure out how to authenticate to the epic game store. The part I struggle with is generating cookies for the epic game store.

Note: This is a workaround i found which works. Its a bit tedious and manual at this point. 😔😔

The DeviceAuthGenerator throws error, however i was able to get the info required for device_auths.json by following the instructions here. These are the steps I followed:

1. Ensure you are logged into epicgames with you account in ur browser
2. Get authorization_code by opening this link in browser. The client id i've used is for fortniteIosClient.
3. Get access code by using the authorization code from step 2.

   curl --location --request POST 'https://account-public-service-prod.ol.epicgames.com/account/api/oauth/token' \
   --header 'Authorization: Basic MzQ0NmNkNzI2OTRjNGE0NDg1ZDgxYjc3YWRiYjIxNDE6OTIwOWQ0YTVlMjVhNDU3ZmI5YjA3NDg5ZDMxM2I0MWE=' \
   --header 'Content-Type: application/x-www-form-urlencoded' \
   --data-urlencode 'grant_type=authorization_code' \
   --data-urlencode 'code={{code_from_step_2}}'

4. Use the access code from step 3 to get the details using the following curl

   curl --location --request POST 'https://account-public-service-prod.ol.epicgames.com/account/api/public/account/{{your_account_id}}/deviceAuth' \
   --header 'Authorization: Bearer {{bearer_token_from_step_3}}'

5. You still need to manually store the response in the device_auths.json with your email as json key.

However even after doing so and creating the device_auths.json file, when running the claimer.js, it was still asking for exchange code. As a work around, i got the exchange code from following instructions here and tweaked the code in claimer.js as shown in the screenshot.

Not sure if this is all the effort, but for someone who is looking for a quick fix this will work. Hope this helps!

Wow I didn't know https://github.com/MixV2/EpicResearch exists. Thanks for document @aneem, it helps :).

I also have the same issue with DeviceAuthGenerator-issue3 and with the document, I think I fixed the issue. Will push a patch to my fork after I do more test.

I fixed the issue with DeviceAuthGenerator here: https://github.com/xMistt/DeviceAuthGenerator/issues/3#issuecomment-924350309

I think we can continue to use this method to export the tokens.

Well, if we can make the fnbrjs library working, we no longer have to rely on third party apps, or abandoned libraries. :)
