Asp.net core 如何在每次IdentityServer4 api调用中获取客户端信息？（用于记录）

我有一个受identityServer4保护的api：

   services.AddAuthentication(defaultScheme: IdentityServerAuthenticationDefaults.AuthenticationScheme)
        .AddIdentityServerAuthentication(options =>
        {
            options.Authority = "https://localhost:5000";
            options.ApiName = "api1";
            options.ApiSecret = "secret";

            options.EnableCaching = true;
            options.CacheDuration = TimeSpan.FromMinutes(10); // that's the default
        });

    // adds an authorization policy to make sure the token is for scope 'api1'
    services.AddAuthorization(options =>
    {
        // some policies here
    });

我想用客户机信息（如：

ClientId、ClientName，

）记录每个客户机的api调用（不仅仅是身份验证）。 以下是我的拦截器中间件：

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILogger logger)
{
    app.UseHttpsRedirection();
            
    app.Use(async (context, next) =>
    {                
        // Log the incoming request here (e.g clientId, clientName, ...)
        await next.Invoke();
     });

     // ...
}

// Write streamlined request completion events, instead of the more verbose ones from the framework.
// To use the default framework request logging instead, remove this line and set the "Microsoft"
// level in appsettings.json to "Information".
app.UseSerilogRequestLogging();

---

我该怎么做呢？

您可以添加Serilog ASP.NET核心以记录所有详细信息

然后还可以使用SerilogRequestLogging中间件：

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILogger logger)
{
    app.UseHttpsRedirection();
            
    app.Use(async (context, next) =>
    {                
        // Log the incoming request here (e.g clientId, clientName, ...)
        await next.Invoke();
     });

     // ...
}

// Write streamlined request completion events, instead of the more verbose ones from the framework.
// To use the default framework request logging instead, remove this line and set the "Microsoft"
// level in appsettings.json to "Information".
app.UseSerilogRequestLogging();

参见sameple代码

我最终捕获了OAuth2事件：

options.OAuth2IntrospectionEvents.OnTokenValidated = async (context) =>
{
   var identity = context.Principal.Identity as ClaimsIdentity;
   identity.AddClaim(new Claim("my_claim", "claim_value"));
   // ...
   // log the request   
}

不，我对NLog、Serilog等日志框架没有问题。我想拦截IS4 api调用。
