Access token not beeing refreshed automatically

my application support old dropbox and the new one.

when creating the client i am creating it like this


client = new DropboxTeamClient(request.AccessToken, request.RefreshToken,request.Expires,ClientId,ClientSecret);

and then using it 

in this way 

first Way

var members = await client.Team.MembersListAsync().ConfigureAwait(false);

 

and this way 

Second Way

var account = await client.AsMember(request.AsMember).Users.GetCurrentAccountAsync();
var clientNew= client.AsMember(request.AsMember).WithPathRoot(new PathRoot.Root(account.RootInfo.RootNamespaceId));

var folders = await spaceclient.Files.ListFolderAsync(folderId);

 

 

my issue is after 4 hours when the token is expired 

When i calling the  first way i am getting an error 

Response status code does not indicate success: 400 (Bad Request).

it is look like it is failing on refreshing token .

 

the problem is that this request is not exist in the new client 

Team.MembersListAsync(). not exist in the new client

 

 

please advice 🙂

 

Any Update Please 

maybe this method client.Team.MembersListAsync() not handling as it should with the refresh token

    Omri1984 It sounds like there's an issue with the credentials you're supplying, so trying the call outside of the SDK as Здравко suggested should be a useful test.

    I added some logs to check my cred during the running .

    I will update here, it holiday now so in a few days ,

    thanks for the help.

     

    by the way.

     

    if create a new DropboxTeamClient(request.AccessToken, request.RefreshToken,request.Expires,ClientId,ClientSecret);

     

     

    can I call those methods

     

    var account = await client.AsMember(request.AsMember).Users.GetCurrentAccountAsync();
    var spaceclient = client.AsMember(request.AsMember).WithPathRoot(new PathRoot.Root(account.RootInfo.RootNamespaceId));

    if (account.RootInfo.IsTeam)
    {
    await spaceclient.Files.ListFolderAsync(folderId)

    }

    await client.Team.MembersListAsync()

     

    await client.AsMember(request.AsMember).Files.ListFolderAsync(folderId)

     

     

    and another question ,When using the .Net SDK when is the refresh token is happening?

    does it happen for every method ?

    does it happen when creating the client (new DropboxTeamClient(request.AccessToken, request.RefreshToken,request.Expires,ClientId,ClientSecret);)

     

    Thank you

    Hi Omri1984,

    Overall idea is correct (only representation change 😉); you may need to check your syntax, etc in your end variant. Additional optimization can be done as "cache" your 'representation' , if in particular limited place multiple calls need to be performed sequentially (less objects construct/destruct -> will left one representation construct at beginning and one destruct at the end).

    Yes and No. On every method call, SDK (all of them - not only .Net) check if current access token exists and its validity. That's what's done mandatory. If there is not available access token or it's going to expire (or already expired), refresh gets performed (which means once on every 4 hours roughly, if you use your code continuously).

    No, it doesn't happen on client object creation time, but on methods execution (as I mentioned above). Warning: on client object creation, the state is reset, which means almost mandatory first call will need to refresh the token! As mentioned something meaningless. That's why it's not good idea to create client object continuously for every call, cosa the call gonna be forced to refresh (not the object construction itself). ".Net" SDK implementation doesn't provide currently some way to keep current state (like Java SDK or Python SDK). That's why the last state can't be restored (without some hacks/patches). Seems like a design bug. Let's hope this bug will be fixed.

    Hope it's a bit more clear now.
