ServiceStack自动解包异常

Question

我发现ServiceStack 4会自动解开异常，如何防止这种情况？

例如，我暴露了以下API。

public async Task GET(XXXRequest request)
{
    try
    {
    throw new Exception("#inner");
    }
    catch(Exception ex)
    {
    throw new Exception("#outer", ex);
    }
}

我有一个记录器捕获错误

Plugins.Add(new RequestLogsFeature()
{
  EnableRequestBodyTracking = true,
  EnableResponseTracking = true,
  EnableErrorTracking = true,
  RequestLogger = new CustomRequestLogger()
});

class CustomRequestLogger : InMemoryRollingRequestLogger
{

    public override void Log(IRequest request, object requestDto, object response, TimeSpan requestDuration)
    {
        base.Log(request, requestDto, response, requestDuration);

        // handle errors
        HttpError httpError = response as HttpError;
        if (httpError != null)
        {
            // log error
        // httpError is #inner
        return;
        }
    }
}

问题在于：我只捕获了内部异常，外部异常消失了

您可以在AppHost中禁用此功能：

SetConfig(new HostConfig {
    ReturnsInnerException = false,
});
