我正在尝试在 Azure Function v4 项目中用 Serilog 替换 Microsoft.Extensions.Logging。
Serilog 正在使用下面的配置工作，但看起来所有日志条目都是通过 Microsoft.Extensions.Logging “管道传输”的，而不是由 Serilog 写入控制台。 查看输出：
[2024-10-23T13:31:26.843Z] Executing 'Functions.TestTrigger' (Reason='This function was programmatically called via the host APIs.', Id=efe14143-428e-4ac8-a498-1abeae4aa53d)
[2024-10-23T13:31:26.917Z] [15:31:26 INF] Retrieved request
第 1 行由框架记录，第 2 行由我们的代码使用 Serilog 记录。 第 2 行的第二个时间戳是由 Serilog 写入的。
是否可以通过Serilog将所有日志条目直接写入控制台？
此外，如果我将 host.json 中的默认日志级别更改为“调试”以外的任何级别，则不会写入 Serilog 中的任何条目。
我错过了什么？
程序.cs：
var host = new HostBuilder()
.ConfigureFunctionsWorkerDefaults()
.ConfigureServices(services =>
{
services.AddApplicationInsightsTelemetryWorkerService(x => { x.EnableAdaptiveSampling = false; });
services.ConfigureFunctionsApplicationInsights();
})
.ConfigureLogging(loggerBuilder =>
{
Log.Logger = new LoggerConfiguration()
.Enrich.FromLogContext()
.WriteTo.Console(LogEventLevel.Debug)
.CreateBootstrapLogger();
loggerBuilder.AddSerilog(Log.Logger, true);
})
.UseSerilog((_, sp, loggerCfg) => loggerCfg
.Enrich.FromLogContext()
.WriteTo.Console(LogEventLevel.Debug)
.WriteTo.ApplicationInsights(sp.GetRequiredService<TelemetryClient>(), TelemetryConverter.Traces))
.Build();
host.Run();
主机.json：
{
"version": "2.0",
"logging": {
"logLevel": {
"default": "Debug"
}
}
}
我们使用 NuGet 包中的 Serilog 引导记录器Serilog.AspNetCore。 这允许我们在本地调试时查看消息。 它稍后允许我们更新记录器。 您可以在Nicholas Blumhardt 的博客上阅读有关引导记录器的更多信息。 我们还在 appsettings.json 中设置 Serilog。 您应该能够从包中提取 Microsoft.Extensions.Logging。希望您可以使用我们的配置来帮助您。
使用的 NuGet 包：
Log.Logger = new LoggerConfiguration()
.MinimumLevel.Debug()
.MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
.MinimumLevel.Override("Microsoft", LogEventLevel.Information)
.Enrich.FromLogContext()
.WriteTo.Console()
.CreateBootstrapLogger(); //https://nblumhardt.com/2020/10/bootstrap-logger/
try
{
Log.Debug("Starting web application.");
var builder = WebApplication.CreateBuilder(args);
IConfigurationRoot configuration;
var configurationBuilder = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
configuration = configurationBuilder.Build();
var env = configuration.GetValue(typeof(string), "environmentVariables:ASPNETCORE_ENVIRONMENT")!.ToString();
var builder = WebApplication.CreateBuilder(new WebApplicationOptions
{
Args = args,
EnvironmentName = env,
});
builder.Host.UseSerilog((context, services, configuration) => configuration
.ReadFrom.Configuration(context.Configuration)
.ReadFrom.Services(services)
.Enrich.FromLogContext()
);
var app = builder.Build();
/* Setup App i.e. app.UseAuthentication(); */
app.UseSerilogRequestLogging(options =>
{
// Customize the message template
options.MessageTemplate = "{RequestPath} responded {StatusCode} in {Elapsed}";
// Emit debug-level events instead of the defaults
options.GetLevel = (httpContext, elapsed, ex) => LogEventLevel.Debug;
// Attach additional properties to the request completion event
options.EnrichDiagnosticContext = (diagnosticContext, httpContext) =>
{
diagnosticContext.Set("RequestHost", httpContext.Request.Host.Value);
diagnosticContext.Set("RequestScheme", httpContext.Request.Scheme);
//diagnosticContext.Set("StatusCode", httpContext.Response.StatusCode);
};
});
app.Run();
