AcquireTokenSilent() 是 Microsoft.Identity.Client 库中的一个方法,用于在不需要用户进行交互的情况下获取访问令牌。在某些情况下,该方法可能会失败。以下是一些可能的解决方法,可以用来解决 AcquireTokenSilent() 失败的问题:
AuthenticationResult result;
try
{
result = await app.AcquireTokenSilent(scopes, account).ExecuteAsync();
}
catch (MsalUiRequiredException)
{
result = await app.AcquireTokenInteractive(scopes).ExecuteAsync();
}
var accounts = await app.GetAccountsAsync();
AuthenticationResult result;
try
{
result = await app.AcquireTokenSilent(scopes, accounts.FirstOrDefault()).ExecuteAsync();
}
catch (MsalUiRequiredException)
{
// Handle the case where a token cannot be acquired silently
}
AuthenticationResult result;
try
{
result = await app.AcquireTokenSilent(scopes, account)
.WithForceRefresh(true)
.ExecuteAsync();
}
catch (MsalUiRequiredException)
{
// Handle the case where a token cannot be acquired silently
}
这些是一些常见的解决方法,可以用来解决 AcquireTokenSilent() 失败的问题。根据具体情况,您可能还需要进一步调查失败的原因,并采取相应的解决方法。
