上文说到Nlog日志框架，感觉它功能已经很强大，今天给大家介绍一个很不错的日志框架Serilog，根据我的了解，感觉它最大的优势是，结构化日志，它输出的日志是Json的格式，如果你使用的是Mongodb进行存储日志，那就是完美的结合，MongoDB也是文档式数据库，存储的格式很像JSON，也可以它是一个JSON文件，查询数据库快。不扯远了，还是讲讲Serilog的使用吧！
Serilog 是 ASP.NET Core 的一个插件，可以简化日志记录。Serilog 有各种可用的接收器，例如，有纯文本、SQL 和 ElasticSearch 接收器等等。
Install-Package Serilog.AspNetCore
3.1Program的配置如下
public class Program
{
public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())//设置基础路径
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)//添加配置文件
.AddEnvironmentVariables()//添加环境变量
.Build();
public static void Main(string[] args)
{
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
.MinimumLevel.Debug()
.Enrich.FromLogContext()//使用Serilog.Context.LogContext中的属性丰富日志事件。
.WriteTo.Console(new RenderedCompactJsonFormatter())//输出到控制台
.WriteTo.File(formatter:new CompactJsonFormatter(),"logs\\test.txt",rollingInterval:RollingInterval.Day)//输出到文件
.CreateLogger();//清除内置日志框架
try
{
Log.Information("Starting web host");
CreateHostBuilder(args).Build().Run();
}
catch (Exception ex)
{
Log.Fatal(ex,"Host terminated unexpectedly");
}
finally
{
Log.CloseAndFlush();
}
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args).
.ConfigureWebHostDefaults(webBuilder =>{
webBuilder.UseStartup<Startup>();
}).UseSerilog(dispose:true);//引入第三方日志框架
3.2 appsettings.json配置
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"AllowedHosts": "*",
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"System": "Information"
}
}
}
}
因为是替换了.net core中的内部日志框架，所有在使用的时候，和Logging日志框架一样使用，如下图所示
private readonly ILogger<WeatherForecastController> _logger;
public WeatherForecastController(ILogger<WeatherForecastController> logger)
{
_logger = logger;
}
[HttpGet]
public void Get()
{
_logger.LogInformation("LogInformation" + Guid.NewGuid().ToString("N"));
_logger.LogDebug("LogDebug" + Guid.NewGuid().ToString("N"));
_logger.LogWarning("LogWarning" + Guid.NewGuid().ToString("N"));
_logger.LogError("LogError" + Guid.NewGuid().ToString("N"));
}

6.1分级别显示
//存储日志文件的路径
string LogFilePath(string LogEvent) => $@"{AppContext.BaseDirectory}00_Logs\{LogEvent}\log.log";
//存储日志文件的格式
string SerilogOutputTemplate = "{NewLine}{NewLine}Date：{Timestamp:yyyy-MM-dd HH:mm:ss.fff}{NewLine}LogLevel：{Level}{NewLine}Message：{Message}{NewLine}{Exception}" + new string('-', 50);
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
.MinimumLevel.Debug()
.Enrich.FromLogContext()//使用Serilog.Context.LogContext中的属性丰富日志事件。
.WriteTo.Console(new RenderedCompactJsonFormatter())
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Debug).WriteTo.File(LogFilePath("Debug"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Information).WriteTo.File(LogFilePath("Information"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Warning).WriteTo.File(LogFilePath("Warning"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Error).WriteTo.File(LogFilePath("Error"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.WriteTo.Logger(lg => lg.Filter.ByIncludingOnly(p => p.Level == LogEventLevel.Fatal).WriteTo.File(LogFilePath("Fatal"), rollingInterval: RollingInterval.Day, outputTemplate: SerilogOutputTemplate))
.CreateLogger();
效果如下：

6.2存储到数据库
Install-Package Serilog.Sinks.MSSqlServer
修改配置
MSSqlServer(参数一，参数二，参数三，参数四)
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.ReadFrom.Configuration(new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.Build())
.WriteTo.MSSqlServer(connecting, "logs", autoCreateSqlTable: true, restrictedToMinimumLevel: LogEventLevel.Information)
.CreateLogger();
效果如下：
6.2.1数据库中表字段
新增
第一步：创建列
var options = new ColumnOptions();
options.AdditionalColumns = new Collection<SqlColumn>
{
new SqlColumn { DataType = SqlDbType.NVarChar, DataLength =-1, ColumnName = "IP" },
};
第二步：添加列
Enrich.WithProperty:添加属性
columnOptions: options：配置数据库的列
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
.MinimumLevel.Information()
.Enrich.WithProperty("IP", "2.2.2.2")
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.ReadFrom.Configuration(new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.Build())
.WriteTo.MSSqlServer(connecting, "logs", autoCreateSqlTable: true, columnOptions: options, restrictedToMinimumLevel: LogEventLevel.Information)
.CreateLogger();
第三步：运行即可
移除
第一步：记录移除列
StandardColumn:是框架默认提供数据库默认表，它的属性就是映射数据库的字段
var options = new ColumnOptions();
options.Store.Remove(StandardColumn.Properties);
options.Store.Remove(StandardColumn.TimeStamp);
第二步：配置属性
Log.Logger = new LoggerConfiguration().ReadFrom.Configuration(Configuration)
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.ReadFrom.Configuration(new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.Build())
.WriteTo.MSSqlServer(connecting, "logs", autoCreateSqlTable: true, columnOptions: options, restrictedToMinimumLevel: LogEventLevel.Information)
.CreateLogger();
第三步：运行即可
注意事项：
当你创建了数据库的表之后，如果修改添加字段或修改字段，数据库存在的表是不会更新的，只能重新创建
6.3发送到邮箱
添加安装包:
Install-Package Serilog.Sinks.Email
配置如下:
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Information()
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.ReadFrom.Configuration(new ConfigurationBuilder()
