.net5 Serilog使用
一,安装包 Serilog.AspNetCore
1,startup.cs 添加 // Serilog请求日志中间件---必须在 UseStaticFiles 和 UseRouting 之间
app.UseSerilogRequestLogging();
2,方式一 在program.cs
static string LogFilePath(string LogEvent) => $@"{AppContext.BaseDirectory}\Logs\{LogEvent}\log.log"; static string SerilogOutputTemplate = "【时间】{Timestamp:yyyy-MM-dd HH:mm:ss,fff}{NewLine}【等级】{Level:u3}{NewLine}【消息】{Message:lj}{NewLine}{Exception}{NewLine}";
在CreateHostBuilder 中添加
.UseSerilog((context, logger) => { logger.Enrich.FromLogContext(); logger.WriteTo.Console();//输出到控制台
logger.MinimumLevel.Debug();// 所有Sink的最小记录级别
logger.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)); });
3,方式二 读取配置模板
.UseSerilog((context, logger) =>
{
logger.ReadFrom.Configuration(context.Configuration);
logger.Enrich.FromLogContext();
logger.WriteTo.Console();
});
appsettings.json
{ "Serilog": { "MinimumLevel": { "Default": "Debug", "Override": { "Default": "Warning", "System": "Warning", "Microsoft": "Warning" } }, "WriteTo": [ { "Name": "Console" }, //输出到控制台 { "Name": "Async", //异步写入日志 "Args": { "configure": [ { "Name": "File", //输出文件 "Args": { "path": "logs/.log", "outputTemplate": "{NewLine}Date:{Timestamp:yyyy-MM-dd HH:mm:ss.fff}{NewLine}LogLevel:{Level}{NewLine}Class:{SourceContext}{NewLine}Message:{Message}{NewLine}{Exception}", "rollingInterval": "3" //日志文件生成精度:1:年 2:月 3:日 4:小时 } } ] } } //{ // "Name": "Console", // "Args": { // "outputTemplate": "时间{Timestamp:yyyy-MM-dd HH:mm:ss,fff}{NewLine}等级{Level:u3}{NewLine}消息{Message:lj}{NewLine}{NewLine}" // } //}, //{ // "Name": "File", // "Args": { // "path": "logs/.log", // "rollingInterval": "Day", // "outputTemplate": "【时间】{Timestamp:yyyy-MM-dd HH:mm:ss,fff}{NewLine}【等级】{Level:u3}{NewLine}【消息】{Message:lj}{NewLine}{NewLine}" // } //} ] }
配置文件模板 输出模板
SerilogOutputTemplate 中的中文输出乱码问题不知道为啥
