抑制来自工作单元事务的错误

Question

我试图抑制代码中的错误，但 MVC 操作仍然returns“500 内部服务器错误”。

操作后 ASP.NET 样板框架中触发了哪些事件 returns？

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 块中恢复，请从 UnitOfWork 开始 RequiresNew:

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 });
}
