我正在使用 Xamarin.Auth 对foursquare 等服务进行身份验证。我的身份验证代码运行良好,问题是当我部署新版本的应用程序时帐户数据没有保留 - 每次我在手机上部署测试版本时,我都必须重新进行身份验证。
这是我存储帐户的方式;
/// <summary>
/// Stores the account.
/// </summary>
private void StoreAccount(AuthenticatorCompletedEventArgs eventArgs)
{
if (!eventArgs.IsAuthenticated) // make sure we are authenticated.
{
Log.Debug(Logging.AppTag, "FourSquareClient can't store account as auth. is cancelled. ");
return;
}
this.IsAuthenticated = true;
this.Account = eventArgs.Account;
AccountStore.Create(this.OwnerContext).Save(eventArgs.Account, "Foursquare");
}
这是我检查我们是否有存储帐户的方法;
/// <summary>
/// Retrieves stored account.
/// </summary>
private void RetrieveAccount()
{
if (this.IsAuthenticated)
{
Log.Debug(Logging.AppTag, "FourSquareClient is already authenticated! ");
return;
}
var accounts = AccountStore.Create(this.OwnerContext).FindAccountsForService("Foursquare");
var enumerable = accounts as IList<Account> ?? accounts.ToList();
if (enumerable.Any())
{
Log.Info(Logging.AppTag, "Foursquareclient found account data.");
this.IsAuthenticated = true;
this.Account = enumerable.First();
}
else
{
Log.Info(Logging.AppTag, "Foursquareclient no account data found!");
this.IsAuthenticated = false;
this.Account = null;
}
}
