Serilog

serilog日志

serilog日志簡單方法
1安裝包

第一個是基礎(chǔ)的配置，第二個包是集成Serilog日志記錄器的擴展包，簡化在.NET應(yīng)用程序中集成和配置Serilog的過程。第三個是保存在文檔中

2 配置文件

public static void AddSerilog(this WebApplicationBuilder builder)

{

Log.Logger = new LoggerConfiguration()

.MinimumLevel.Override("Microsoft", LogEventLevel.Warning) // 排除Microsoft的日志

.Enrich.FromLogContext() // 注冊日志上下文

.WriteTo.Logger(configure => configure // 輸出到文件

.MinimumLevel.Debug()

.WriteTo.File(

$"logs\\log.txt", // 單個日志文件，總?cè)罩荆腥罩敬娴竭@里面

rollingInterval: RollingInterval.Day,

outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss} [{Level:u20}] {Message:lj}{NewLine}"

)

)

.CreateLogger();

builder.Host.UseSerilog();

}

Program：

//全局異常計入日志

serilog存入數(shù)據(jù)庫并到txt文檔分表，并顯示

1. 配置文檔，注入，用哪個裝那個
2. 

/// <summary>

/// Serilog日志

/// </summary>

/// <param name="builder"></param>

public static void AddSerilog(this WebApplicationBuilder builder)

{

var configuration = new ConfigurationBuilder()

.SetBasePath(Directory.GetCurrentDirectory())

.AddJsonFile("appsettings.json")

.AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", true)

.Build(); // 讀取配置文件

var connectionString = configuration["ConnectionStrings:Con"].Trim(); // 獲取默認的數(shù)據(jù)庫連接字符串

Log.Logger = new LoggerConfiguration()

.ReadFrom.Configuration(configuration) // 讀取配置文件中的配置

.WriteTo.Console(theme: AnsiConsoleTheme.Code) // 寫入控制臺輸出，且使用 AnsiConsoleTheme.Code 主題

.WriteTo.Map( // 動態(tài)配置

keyPropertyName: "Name", // 鍵屬性名

defaultKey: "0", // 默認鍵值

configure: (name, wt) => wt.Logger(lc => lc // 配置單個log

.WriteTo.MSSqlServer( // 寫入MSSQL

connectionString: connectionString, // 使用默認的數(shù)據(jù)庫連接字符串

sinkOptions: new MSSqlServerSinkOptions

{

TableName = $"LogEvents_{name}", // 動態(tài)表名

AutoCreateSqlTable = true // 自動創(chuàng)建表

})

.WriteTo.File($"logs\\log_{name}.txt", rollingInterval: RollingInterval.Day)) // 寫入日志文件

)

.CreateLogger(); // 創(chuàng)建log

}

"Serilog": {

"MinimumLevel": "Information" //日志輸出最小級別

},最小輸出級別

讀取文檔方法
