asp.net mvc Web アプリケーションがあり、外部の cron ジョブが特定の URL を呼び出して、CronJobController
次のような特定のメソッドを実行しています。
/// <summary>
/// Will be called externally by www.setcronjob.com.
/// </summary>
/// <returns></returns>
public async Task<ActionResult> Index()
{
RunTwitterSearchQuery();
RunFacebookSearchQuery();
return new ContentResult { Content = "Ok" };
}
RunTwitterSearchQuery で、いくつかのメールを送信したいので、たとえばMvcMailerとActionMailerの両方を試しました(ActionMailer を使用):
var mailController = new MailController();
mailController.HttpContextBase = this.HttpContext;
mailController.MoreThanXFollowersEmail(alertEmailModel).Deliver();
http コンテキストが null であるため、NPE を回避するためにこのように設定する必要がありますが、その後、非常に奇妙な例外を受け取ります (MvcMailer と ActionMailer の両方で):

これは非常に醜いので、この問題について何か助けていただければ幸いです。
更新: MvcMailer を使用している場合、これは私が受け取るエラーです。
