如何在ASP.NET核心MVC中使用IExceptionHandler？

public class CustomExceptionHandler : IExceptionHandler
{
    public async Task HandleExceptionAsync(ExceptionContext context)
    {
        // 处理异常逻辑
        // 例如记录日志、生成自定义响应等

        // 设置响应状态码
        context.HttpContext.Response.StatusCode = (int)HttpStatusCode.InternalServerError;

        // 设置响应内容
        context.Result = new JsonResult(new
        {
            error = "An unexpected error occurred."
        });

        // 执行异常处理
        await Task.CompletedTask;
    }
}

public void ConfigureServices(IServiceCollection services)
{
    services.AddControllersWithViews();

    // 注册自定义异常处理器
    services.AddSingleton<IExceptionHandler, CustomExceptionHandler>();
}

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }
    else
    {
        // 使用自定义异常处理器
        app.UseExceptionHandler("/Home/Error");
    }

    app.UseStaticFiles();

    app.UseRouting();

    app.UseAuthorization();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");
    });
}
