Dropbox SDK JS + Refresh token problem

[Alex57600]

Hello

Please, do you have any idea how i can manage this ? Each 4 hours i get "expired_access_token" and user must re-log.

I just upgrade my old Dropbox SDK JS to the last version 10.8.0 + I did the changes to be compatible.

I have one Cordova app (iOS/Android/Win10).

The goal of my app is to : 1. User connect on dropbox (long life), user set "working hours" on my app, then each day/week user save/load data to/from Dropbox.

Here's my code:

Connexion code:

// 1. I init Dropbox connexion
dbx = new Dropbox.Dropbox({
  clientId: dropboxClientId
});



// 2. I get auth url with redirect (custom url scheme)
var dropboxRedirectUri = 'MYAPP://dropbox_callback';

dbx.auth.getAuthenticationUrl(
  dropboxRedirectUri,
  '',
  'code',
  'offline',
  [
    'files.content.write',
    'files.content.read',
  ],
  'user',
  true
)
.then((authUrl) => {
  dropboxCodeVerifier = dbx.auth.codeVerifier;
  cordova.InAppBrowser.open(authUrl, '_system');
});

// 3. User is redirect to his web browser to logoff, then user is redirected to my app
function handleOpenURL(url) {
  // I read the "code" send by Dropbox
  if (getUrlVars(url).code) {
   dbx.auth.setCodeVerifier(dropboxCodeVerifier);
   dbx.auth.getAccessTokenFromCode(dropboxRedirectUri, getUrlVars(url).code)
   .then((response) => {
      // I get the "access_token" (starts with sl as short-life)     
      localStorage['dropbox_access_token'] = response.result.access_token;
   })
   .then((response) => {
     ... User is now connected
   })
   .catch((error) => {
     alert(error);
    });
}

// At this point, i also get "refresh_token", but I'm sorry i don't know how to use it.
// So, after that, for each user action (save/load) i connect to dropbox + i launch my // actions with this code:

dbx = new Dropbox.Dropbox({
  accessToken: localStorage['dropbox_access_token']
});
dbx.filesUpload({...

To maintain long-term access, you'll need to request "offline" access, as you're doing, and then supply the app key (the app secret isn't needed since you're using PKCE) and refresh token. As long as you do so, the SDK will handle the refresh process for you automatically. You can find an example of setting the refresh token in this example.
