如何在serilog中自定义日志文件

Question

这是我的 serilog 的输出。

 2022-05-24T16:31:13.4340853+05:30  [INF] Application started. Press Ctrl+C to shut down.

我不明白这种 guid 在 8000000e-0000-fd00-b63f-84710c7967bb 中的位置，如何删除这个 guid？

这是我的 startup.cs 文件

   public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        else
        {
            app.UseExceptionHandler("/Error");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

        loggerFactory.AddFile("Logs/EigenLog-{Date}.txt");

        //app.UseHttpsRedirection();
        app.UseStaticFiles();

        app.UseRouting();

        app.UseAuthorization();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapRazorPages();

            endpoints.MapControllers();
        });
    }

GUID 是请求 ID：

https://github.com/serilog/serilog-extensions-logging-file/#file-format

要对其进行自定义，请指定输出模板：

loggerFactory.AddFile("Logs/EigenLog-{Date}.txt", outputTemplate:
    "{Timestamp:o} [{Level:u3}] {Message} {Properties:j} ({EventId:x8}){NewLine}{Exception}"
);
