asp.net-core-mvc - Common.Logging.NLog 不适用于网络核心？

Question

我目前在 netcoreapp1.1 上使用 Common.Logging 版本 3.4.0-beta2 和 NLog 5.0.0-beta07。（它和 ASP Net Core mvc 项目）我找不到针对这种情况的 Common.Logging.NLog 特定版本。

如果它还不可用，我有哪个日志文件选项作为网络核心的适配器？

Answer 1

我终于创建了两个类：

public class CommonLoggingNLogAdapter : ILoggerFactoryAdapter
{
    public ILog GetLogger(Type type)
    {
        return new NLogAdapter(type);
    }

    public ILog GetLogger(string key)
    {
        return new NLogAdapter(key);
    }
}

和

public class NLogAdapter : ILog
{
    private Logger log;

    public bool IsTraceEnabled { get { return log.IsTraceEnabled; } }

    public bool IsDebugEnabled { get { return log.IsDebugEnabled; } }

    public bool IsErrorEnabled { get { return log.IsErrorEnabled; } }

    public bool IsFatalEnabled { get { return log.IsFatalEnabled; } }

    public bool IsInfoEnabled { get { return log.IsInfoEnabled; } }

    public bool IsWarnEnabled { get { return log.IsWarnEnabled; } }

    public IVariablesContext GlobalVariablesContext => throw new NotImplementedException();

    public IVariablesContext ThreadVariablesContext => throw new NotImplementedException();

    public INestedVariablesContext NestedThreadVariablesContext => throw new NotImplementedException();

    public NLogAdapter(Type type)
    {
        log = NLog.LogManager.GetLogger(type.ToString());
    }

    public NLogAdapter(string key)
    {
        log = NLog.LogManager.GetLogger(key);
    }

然后我可以通过执行以下操作将 NLog 配置为记录器：

Common.Logging.LogManager.Adapter = new CommonLoggingNLogAdapter();

这是我正在实施的临时解决方案，直到正式发布。

Answer 2

目前没有 NLog 5 和 Common logging 的包。

替代方案是：

• 库日志：

  1. 只需复制文件 liblog.cs，请参阅网站
  2. 手动将命名空间 YourRootNamespace 重命名为项目的根命名空间。
  3. 启用 LIBLOG_PORTABLE 编译器指令。

• 或者使用微软的日志抽象。请参阅文档如何记录 和安装NLog.Web.AspNetCore，并查看安装说明

Answer 3

您可以在此处找到自定义构建 nuget-package (Common.Logging.NLog45)：

https://github.com/net-commons/common-logging/pull/176

支持 NetCore 和结构化日志记录。
