使用Serilog进行Blazor应用程序日志记录 [英] Blazor application logging with Serilog
本文介绍了使用Serilog进行Blazor应用程序日志记录的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
在Blazor应用程序中,我在main中配置了启动日志,如下所示;
public static void Main(string[] args)
{
var assembly = Assembly.GetExecutingAssembly().GetName();
var appInsightsTelemetryConfiguration = TelemetryConfiguration.CreateDefault();
appInsightsTelemetryConfiguration.InstrumentationKey = "aa11aa11aa-a1a1-a1-aa-a111-aa11";
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Override("Microsoft.AspNetCore", Serilog.Events.LogEventLevel.Warning)
.Enrich.FromLogContext()
.Enrich.WithProperty("Application", $"{assembly.Name}")
.WriteTo.Console()
.WriteTo.Seq(serverUrl: "http://myseqserver.inthecloud.azurecontainer.io:5341/")
.WriteTo.ApplicationInsights(appInsightsTelemetryConfiguration, TelemetryConverter.Traces)
.CreateLogger();
try
{
Log.Information(Constants.Logging.Messages.SERVICE_STARTED, assembly.Name);
var host = CreateHostBuilder(args).Build();
using (var serviceScope = host.Services.CreateScope())
{
var context = serviceScope.ServiceProvider.GetRequiredService<MyDbContext>();
context.Database.Migrate(); // apply outstanding migrations automatically
}
host.Run();
return;
}
catch (Exception ex)
{
Log.Fatal(ex, Constants.Logging.Messages.SERVICE_STARTED, assembly.Name);
return;
}
finally
{
// make sure all batched messages are written.
Log.CloseAndFlush();
}
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.UseSerilog()
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
});
并请求登录启动配置;
public void ConfigureServices(IServiceCollection services)
{
//...
services.AddApplicationInsightsTelemetry("aa11aa11aa-a1a1-a1-aa-a111-aa11");
//...
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
/// ...
// Add this line; you'll need `using Serilog;` up the top, too
app.UseSerilogRequestLogging();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapBlazorHub();
endpoints.MapFallbackToPage("/_Host");
});
}
在我的Blazor页面上,我无法使其工作;
@inject ILogger<ThisRazorPage> Logger
@code{
protected override void OnInitialized()
{
Logger.LogTrace("Log something. Please!");
}
}
但这确实有效;
@inject ILoggerFactory LoggerFactory
@code{
protected override void OnInitialized()
{
var logger = LoggerFactory.CreateLogger<Incident>();
logger.LogTrace("Log something. Please!");
}
}
根据this,.UseSerilog()
方法为ILoggerFactory
添加DI。有没有办法让我在DI框架内对ILogger<T>
执行类似的操作,以便可以使用ILogger<T>
,而不必在每个页面上显式创建LoggerFactory
。
推荐答案
静电方法适合我。
@using Serilog
@code {
Log.Information("Log something. Please!");
}
