Detta fungerade för mig att skriva in filen och PostgreSQL:
- Först skapade jag en ASP.NET Core Web Application (.NET Core).
-
Sedan installerade jag från NuGet:
-
Ändrade följande filer så här:
a) project.json
"buildOptions": { "emitEntryPoint": true, "preserveCompilationContext": true, "copyToOutput": { "includeFiles": [ "nlog.config" ] } }, "publishOptions": { "include": [ "wwwroot", "web.config", "nlog.config" ] }
b) Startup.cs
public class Startup { public Startup(IHostingEnvironment env) { env.ConfigureNLog("nlog.config"); } public void ConfigureServices(IServiceCollection services) { services.AddMvc(); } public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { loggerFactory.AddNLog(); app.UseDeveloperExceptionPage(); app.UseMvc(); app.AddNLogWeb(); } }
c) nlog.config
<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" autoReload="true" internalLogLevel="Warn" internalLogFile="c:\temp\internal-nlog.txt"> <!-- Load the ASP.NET Core plugin --> <extensions> <add assembly="NLog.Web.AspNetCore"/> </extensions> <!-- the targets to write to --> <targets> <target xsi:type="File" name="localFile" fileName="c:\\temp\\nlog-all-${shortdate}.log" layout="${longdate} ${level} ${message} ${logger} ${callsite} ${exception:format=tostring}" /> <target name="database" xsi:type="Database"> <dbProvider>Npgsql.NpgsqlConnection, Npgsql, Version=3.2.1.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7</dbProvider> <connectionString>Server=localhost;Port=5432;User Id=XXX;Password=XXX;Database=TestLog;</connectionString> <commandText> insert into "logs" ("Application", "Timestamp", "Level", "Message", "Logger", "CallSite", "Exception") values (:Application, :Timestamp, :Level, :Message, :Logger, :Callsite, :Exception); </commandText> <parameter name="@Application" layout="TestApp" /> <parameter name="@Timestamp" layout="${longdate}" /> <parameter name="@Level" layout="${level}" /> <parameter name="@Message" layout="${message}" /> <parameter name="@Logger" layout="${logger}" /> <parameter name="@Callsite" layout="${callsite}" /> <parameter name="@Exception" layout="${exception:format=tostring}" /> </target> <!-- write to the void aka just remove --> <target xsi:type="Null" name="blackhole" /> </targets> <!-- rules to map from logger name to target --> <rules> <!--All logs, including from Microsoft--> <logger name="*" minlevel="Debug" writeTo="database" /> <logger name="*" minlevel="Debug" writeTo="localFile" /> <!--Skip Microsoft logs and so log only own logs--> <logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" /> </rules> </nlog>
d) Controller
public class HomeController : Controller { ILogger<HomeController> _logger; public HomeController(ILogger<HomeController> logger) { _logger = logger; } [Route("home/test")] public IActionResult Test() { _logger.LogInformation("Logged test information from home controller."); return Ok("Ok"); } }
