我有一个拥有不同山脉的数据库,在我的Web Api中,我正在尝试记录IP地址,时间和日期以及特定山峰被访问次数的“计数”。如果用户导航到api/Mountains/1
,则应记录该地址的IP地址,日期时间和计数mountain.name
。但我有点迷失在逻辑中,我不知道如何计算每一座山?我没有存储这些信息,所以我希望它可以存放在内存中。
编辑:(从回答更新)
public class MountainsController : ApiController
{
private MountainContext db = new MountainContext();
private int Count;
static Dictionary<int, string> data;
static Dictionary<int, int> dataCounter;
static MountainsController()
{
data = Enumerable.Range(1, 10).ToDictionary(i => i, i => "Mountain " + i.ToString());
dataCounter = Enumerable.Range(1, 10).ToDictionary(i => i, i => 0);
}
// GET: api/Mountains/5
[ResponseType(typeof(Mountain))]
public async Task<IHttpActionResult> GetMountain(int id)
{
Mountain mountain = await db.Mountains.FindAsync(id);
if (mountain == null)
{
return NotFound();
}
if (mountain != null)
{
string mountainName = data[id];
dataCounter[id] = dataCounter[id] + 1;
Count = dataCounter[id];
var host = ((System.Web.HttpContextWrapper)Request.Properties["MS_HttpContext"]).Request.UserHostAddress + "," + mountain.Name + "," + DateTime.Now + "," + Count;
System.IO.File.AppendAllText(@"C:\myfile.txt", host);
}
return Ok(mountain);
}

如果只需要内存中的计数器数据,则可以使用静态字典。 看看这个
using System.Collections.Generic;
using System.Web.Http;
using System.Linq;
namespace WebApplication3.Areas.api.Controllers
{
public class MountainController : ApiController
{
static Dictionary<int, string> data;
static Dictionary<int, int> dataCounter;
static MountainController()
{
data = Enumerable.Range(1, 10).ToDictionary(i => i, i => "Mountain " + i.ToString());
dataCounter = Enumerable.Range(1, 10).ToDictionary(i => i, i => 0);
}
[HttpGet]
public MountainModel GetMountain(int id)
{
string mountainName = data[id];
dataCounter[id] = dataCounter[id] + 1;
return new MountainModel() { Id = id, Name = mountainName, Count = dataCounter[id] };
}
}
public class MountainModel
{
public int Count { get; set; }
public int Id { get; set; }
public string Name { get; set; }
}
}
