asp.net核心api元数据

Question

我正在开发asp.net core 2.1 Web API。基本上，我将需要异步捕获后端中的请求时间，重发uri，requestbody，resepone时间，响应正文，状态码，ipaddress。下面的示例中，我发现它适用于mvc webapi。但不确定如何在asp.net core 2.1中使用它。任何工作样品都会受到高度赞赏。

public class CustomLogHandler : DelegatingHandler

        var response = await base.SendAsync(request, cancellationToken);
        logMetadata = BuildResponseMetadata(logMetadata, response);
        await SendToLog(logMetadata);
        return response;
    }
    private LogMetadata BuildRequestMetadata(HttpRequestMessage request)
    {
        LogMetadata log = new LogMetadata
