How to get an Access Token from a Refresh token from within B4A
Hello All, I have created a refresh token using the method thanks to "Здравко". Manually using a web browser and Windows Command prompt. The command prompt is: curl https://api.dropbox.com/oa...
Hi Brad Henderson,
To be honest I'm not familiar with the environment you're using. On the first look though, it uses OkHttp as underlying library. So you can take a look here for a simplistic example - example how OkHttp works. It may be easier for you to encode everything in the body (i.e. pass in the body text: "grant_type=refresh_token&refresh_token=<REFRESH_TOKEN>&client_id=<APP_KEY>&client_secret=<APP_SECRET>"; replace all "<...>" tags appropriately). Find what matches to desired OkHttp calls exactly in your environment (something, I believe you may do). 😉
Hope this helps.
PS: Just to avoid confusion: The example supposes JSON content, but in your case the content type is different, so instead of "application/json" (as is in the example) you have to set "application/x-www-form-urlencoded" as content type (MediaType in the example).
Hi Brad Henderson,
I see, you have selected that url command as base for what you're going to do. I believe, you have the command tested and it works fine. Right?
Something I cannot understand though, where did you decide from that JSON is sended? 🤔 There is a way to check this. Add one more option to the curl command - '-v' option (from verbose). You will see a lot of things in your terminal - all that curl sends as request and receives back as response. This includes header blocks of both request and response. In both header blocks are corresponding Content-Type headers. Check what curl sends as request content type and tell us is it json or something else.
PS: Bear in mind that when you scroll your terminal back, the response (the later one) will be visible before the request (something that's first in time).
Thanks Здравко,
Changed from JSON to "application/x-www-form-urlencoded" then created a string for the other variables in a string using a string builder.
Works perfectly.
Thanks again
Brad
