我在我的网站上使用gmail apiasp.net但我在获取凭证时选择了Web客户端，但我收到错误。

我用的是GoogleWebAuthorizationBroker。AuthorizeAsync但是

“错误：redirect_uri_mismatch”我收到错误。

如何使用。

UserCredential credential; try{

        using (var stream = new FileStream(json, FileMode.Open, FileAccess.Read))
        {
            credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                new[] { GmailService.Scope.GmailReadonly, GmailService.Scope.MailGoogleCom, GmailService.Scope.GmailModify },
                v1,
                CancellationToken.None,
                new FileDataStore(uygulamaAdi)
                );
        }
        var gmailService = new GmailService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = uygulamaAdi
        });
        return gmailService;
    }
