如何捕获所有web api响应的HttpContext.Response.Headers？

public class ResponseHeaderMiddleware
{
    private readonly RequestDelegate _next;

    public ResponseHeaderMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        var originalStream = context.Response.Body;

        try
        {
            using (var memoryStream = new MemoryStream())
            {
                context.Response.Body = memoryStream;

                await _next(context);

                memoryStream.Seek(0, SeekOrigin.Begin);

                var headers = context.Response.Headers;

                // 在这里可以对headers进行处理，如记录日志、输出到控制台等

                memoryStream.Seek(0, SeekOrigin.Begin);
                await memoryStream.CopyToAsync(originalStream);
            }
        }
        finally
        {
            context.Response.Body = originalStream;
        }
    }
}

app.UseMiddleware<ResponseHeaderMiddleware>();
