我有一个引用以下代码的 Windows 服务。使用下面的方法,我的代码包含一个try..catch块,但它似乎并没有catch RefereshTokenException认为是thrown在下面的方法。显然我的理解async是不正确的。
private async void RefreshTokens()
{
try
{
var cognito = new CognitoApi();
var response = cognito.TokenRefresh(_refreshToken);
if (response.HttpStatusCode == HttpStatusCode.OK)
{
_idToken = new AwsToken(response.AuthenticationResult.IdToken);
_accessToken = new AwsToken(response.AuthenticationResult.AccessToken);
}
else
{
await _signIn(_credentials.SiteId, _credentials.LocationId, null);
}
}
catch (NotAuthorizedException)
{
await _signIn(_credentials.SiteId, _credentials.LocationId, null);
}
catch (Exception ex)
{
throw new RefreshTokenException("Failed refreshing tokens.", ex);
}
}
这是调用的代码 RefreshTokens
public async void Process(QueueMessage queueMessage, Action<QueueMessage> retryAction)
{
_processingCounter.Increment();
try
{
......
IAwsToken idToken = authenticationService.Tokens.IdToken; //This is the code that calls "RefreshTokens" method
........
}
catch (Exception ex)
{
//Code never reaches here...
_logger.Error("Error in ProcessMessage", ex);
}
_processingCounter.Decrement();
}
