Add Username via LogContext in Serilog
问题
我正在.NET Core 6.0 Web API应用程序中使用Serilog进行日志记录。我想将已登录用户的用户名添加到日志中。我的中间件如下：
public class LogUserNameMiddleware
{
private readonly RequestDelegate next;
public LogUserNameMiddleware(RequestDelegate next)
{
this.next = next;
}
public Task Invoke(HttpContext context)
{
LogContext.PushProperty("UserName", context.User.Identity.Name);
return next(context);
}
}
在Program.cs中：
var _logger = new LoggerConfiguration()
.ReadFrom.Configuration(builder.Configuration)
.MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
.Enrich.FromLogContext()
.CreateLogger();
Log.Logger = _logger;
builder.Logging.ClearProviders();
builder.Logging.AddSerilog(_logger);
以及在appsettings中：
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "C:\\Debug\\webapi-.log",
"rollingInterval": "Day",
"outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss} {CorrelationId} {Level:u3}] {Username} {Message:lj}{NewLine}{Exception}"
}
}
]
}
但是用户名称未写入日志。我可以在中间件中看到用户名，但在日志中看不到。我漏掉了什么？
注意：请确保Serilog的版本和配置正确，并且确保在中间件中正确设置了用户名属性。

I am using Serilog for logging in .NET Core 6.0 Web API application. I want to add logged user name to logs. My middleware is
public class LogUserNameMiddleware
{
private readonly RequestDelegate next;
public LogUserNameMiddleware(RequestDelegate next)
{
this.next = next;
}
public Task Invoke(HttpContext context)
{
LogContext.PushProperty("UserName", context.User.Identity.Name);
return next(context);
}
}
and in Program.cs
var _logger = new LoggerConfiguration()
.ReadFrom.Configuration(builder.Configuration)
.MinimumLevel.Override("Microsoft.AspNetCore", LogEventLevel.Warning)
.Enrich.FromLogContext()
.CreateLogger();
Log.Logger = _logger; //new
builder.Logging.ClearProviders();
builder.Logging.AddSerilog(_logger);
and in appsettings
"Serilog": {
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"WriteTo": [
{
"Name": "File",
"Args": {
"path": "C:\\Debug\\webapi-.log",
"rollingInterval": "Day",
"outputTemplate": "[{Timestamp:yyyy-MM-dd HH:mm:ss} {CorrelationId} {Level:u3}] {Username} {Message:lj}{NewLine}{Exception}"
}
}
]
But User name is not writing in logs. I can see user name in middleware but not in logs. What am I missing here?

属性名称区分大小写，您正在推送 UserName，但模板中使用的是 {Username}。统一名称，同时您可能希望在 PushProperty 前后包装使用：
public async Task Invoke(HttpContext context)
{
using (LogContext.PushProperty("Username", context.User.Identity.Name))
{
await next(context);
}
}
英文:
Property names a case-sensitive, you are pushing UserName but template has {Username}. Consolidate names, also you might want to wrap the PushProperty in using:
public async Task Invoke(HttpContext context)
{
using (LogContext.PushProperty("Username", context.User.Identity.Name))
{
await next(context);
}
}
