我的登录功能如下所示：[Function(\'Loginxyz\')]public async Task生成令牌（[HttpTrigger（AuthorizationLevel.Anonymous，\'post\'，路线=&

我的登录功能如下所示：

[Function("Loginxyz")]
public async Task<IActionResult> GenerateToken(
        [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = "user/login")] HttpRequestData req,
        ILogger log)
{
    try
    {
        if (requestData.BarCode != null)
        {
            var localLoginRequest = JsonConvert.DeserializeObject<xyz>(requestBody);
            token = await _tokenService.GenerateToken(localLoginRequest);
        }

        if (token == null)
            return new UnauthorizedResult();

        return new OkObjectResult(new { access_token = token });
    }
    catch (AggregateException ae)
    {
        // Handle multiple exceptions
        foreach (var innerException in ae.InnerExceptions)
        {
            log.LogError(innerException, "An error occurred");
            // Handle the inner exception based on its type
        }

        // Return a specific error response based on the aggregate exception
        return new BadRequestObjectResult("An error occurred");
    }
    catch (AuthenticationServiceException ex)
    {
        // Log the error with detailed message
        log.LogError($"Error during token generation: {ex.Message}", ex);

        // Create a custom error response object
        var errorResponse = new
            {
                Error = ex.Message,
                StatusCode = StatusCodes.Status400BadRequest
            };

        // Return the error response with the appropriate status code
        return new JsonResult(errorResponse) { StatusCode = StatusCodes.Status400BadRequest };
    }
    catch (LoginConflictException ex)
    {
        // Log the error with detailed message
        log.LogError($"Error during token generation: {ex.Message}", ex);

        // Create a custom error response object
        var errorResponse = new
            {
                Error = ex.Message,
                StatusCode = StatusCodes.Status409Conflict
            };

        // Return the error response with the appropriate status code
        return new JsonResult(errorResponse) { StatusCode = StatusCodes.Status409Conflict };
    }
    catch (Exception ex)
    {
        log.LogError($"Error during token generation: {ex.Message}");
        return new StatusCodeResult(StatusCodes.Status500InternalServerError);
    }
}

我的服务类如下所示：

public async Task<TokenResponseDto> GenerateToken(object tokenRequest)
{
    try
    {
        return await tokenGenerator.GenerateToken(tokenRequest);
    }
    catch (Exception ex)
    {
        throw; // Rethrow the exception
    }
}

我在方法中抛出错误 tokenGenerator.GenerateToken ，然后在服务类中重新抛出该错误。我的预期是，当我在服务类中重新抛出错误时，它应该在我的 Azure 函数中被捕获，但这并没有发生。

但是，我从重新抛出中得到的错误是：

调用引发了异常。
异常：System.ArgumentNullException：值不能为空。（参数“logger”）

我已经在我的 cmd 日志中捕获了此信息。

这很令人困惑，因为我抛出了一个自定义错误，与 ArgumentNullException .

有人能帮助我理解这一点吗？
