如何统计.net核心Webapi请求次数；

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
    // 其他配置...

    app.UseMiddleware<RequestCountMiddleware>();

    // 其他配置...
}

public class RequestCountMiddleware
{
    private readonly RequestDelegate _next;
    private readonly ILogger<RequestCountMiddleware> _logger;
    private static int _requestCount = 0;

    public RequestCountMiddleware(RequestDelegate next, ILogger<RequestCountMiddleware> logger)
    {
        _next = next;
        _logger = logger;
    }

    public async Task Invoke(HttpContext context)
    {
        _requestCount++;
        _logger.LogInformation($"当前请求次数: {_requestCount}");

        await _next(context);
    }
}

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

    // 其他配置...

    services.AddScoped<RequestCountMiddleware>();

    // 其他配置...
}
