抑制工作單元事務中的錯誤

Question

我試圖抑制代碼中的錯誤，但是MVC操作仍然返回“ 500內部服務器錯誤”。

返回操作后，ASP.NET Boilerplate框架中會觸發哪些事件？

public async Task<IActionResult> Post([FromBody]PaymentViewModel model)
{
    var result = false;

    // Storing of card must pass
    try
    {
        // ...
    }
    catch (Exception ex)
    {
        // Catch business exception, but storing
    }

    return Json(new { result });
}

Answer 1

要在catch塊中恢復，請從RequiresNew開始UnitOfWork ：

public async Task<IActionResult> Post([FromBody]PaymentViewModel model)
{
    var result = false;

    // Storing of card must pass
    try
    {
        using (var uow = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
        {
            // ...

            await CurrentUnitOfWork.SaveChangesAsync();
            await uow.CompleteAsync();
        }
    }
    catch (Exception ex)
    {
        // Catch business exception, but storing
    }

    return Json(new { result });
}
