【BlogBook书】6、Serilog：日志管理

框架高度集成Serilog，继承ASP.NETCore官方的ILogger<>接口，作为记录整个系统应用生命周期的日志工具，涵盖了平时企业应用的常见场景：

1、不同日志级别的记录；2、支持将日志输出到控制台；3、支持日志持久化到数据库；4、支持完整记录Sql执行日志；5、支持输出日志到文件；6、支持配置Seq日志中心；

一、相关的依赖注入配置

builder.Host.AddSerilogSetup();

app.UseSerilogRequestLogging(options =>{    options.MessageTemplate = SerilogRequestUtility.HttpMessageTemplate;    options.GetLevel = SerilogRequestUtility.GetRequestLevel;    options.EnrichDiagnosticContext = SerilogRequestUtility.EnrichFromRequest;});

相关参数设置

"Serilog": {    "MinimumLevel": {      "Default": "Debug",      "Override": {        "Microsoft": "Information",        "Microsoft.AspNetCore": "Warning",        "System": "Warning",        "System.Net.Http.HttpClient": "Warning",        "Hangfire": "Information",        "Magicodes": "Warning",        "DotNetCore.CAP": "Information",        "Savorboard.CAP": "Information",        "Quartz": "Information"      }    }  },

还有日志入库的数据库连接字符串配置

"DBS": [      /*      对应下边的 DBType      MySql = 0,      SqlServer = 1,      Sqlite = 2,      Oracle = 3,      PostgreSQL = 4,      Dm = 5,//达梦      Kdbndp = 6,//人大金仓    */        {      "ConnId": "Log", //日志库连接固定名称，不要改,其他的可以改      "DBType": 2,      "Enabled": true,      "HitRate": 50,      "Connection": "WMBlogLog.db" //sqlite只写数据库名就行，可以替换其他数据库，并修改DBType即可    },]

还有一些配合其他功能（比如Aop、Sqlsugar等）的相关参数设置

"AppSettings": {    "LogToDb": true,    "LogAOP": {      "Enabled": false,      "LogToFile": {        "Enabled": true      },      "LogToDB": {        "Enabled": true      }    },    "UserAuditAOP": {      "Enabled": false    },    "SqlAOP": {      "Enabled": true,      "LogToFile": {        "Enabled": true      },      "LogToDB": {        "Enabled": true      },      "LogToConsole": {        "Enabled": true      }    }  },

最后还有Seq平台相关配置

"Seq": {    "Enabled": true,    "Address": "http://localhost:5341/",    "ApiKey": ""  }

二、使用方式

1、直接注入ILogger<>泛型接口即可

private readonly ILogger<BlogController> _logger;
/// <summary>/// 构造函数/// </summary>/// <param name="logger"></param>/// public BlogController(ILogger<BlogController> logger){    _logger = logger;}

[HttpGet][Route("DetailNuxtNoPer")]public async Task<MessageModel<BlogViewModels>> DetailNuxtNoPer(long id){    _logger.LogInformation("xxxxxxxxxxxxxxxxxxx");    return Success(await _blogArticleServices.GetBlogDetails(id));}

2、或直接使用Serilog的Log类

[HttpGet][Route("DetailNuxtNoPer")]public async Task<MessageModel<BlogViewModels>> DetailNuxtNoPer(long id){    Log.LogInformation("yyyyyyyyyyyyyyy");    return Success(await _blogArticleServices.GetBlogDetails(id));}
