登錄的逻輯應該是
session中存儲用戶的主要信息
key:guid類型
value: 用戶的信息
cookie中存儲效勞端的session的數據類型
key:CurrentUser //這是一個固定的值
value: session中的key的名字
- 相關代码如下:
登錄控製器
//這是一個空過濾過濾器,表示該控製器里的都不停止過濾
[CustomAllowAnonymous]
public class SessionLoginController : Controller
{
[HttpGet]
public IActionResult SessionLogins(int a)
{
if (a == 1)
{
#region Cookie/Session 本人寫 普通運用Sessio爲主
CurrentUser currentUser = new CurrentUser()
{
Id = 123,
Name = "wangjin",
Account = "Administrator",
Email = "1293604064",
Password = "123456",
LoginTime = DateTime.Now
};
//生成一個guid的值用來存儲主键的值
Guid sessionKey = Guid.NewGuid();
//寫Session/寫Cookies
base.HttpContext.SetCookies("CurrentUser", sessionKey.ToString(), 30);
//寫入session
base.HttpContext.Session.SetString(sessionKey.ToString(), Newtonsoft.Json.JsonConvert.SerializeObject(currentUser));
#endregion
return base.Redirect("/Home/Index");
}
return View();
}
}
辦法過濾器
///
/// 辦法過濾器
///
public class CustomActionFilterAttribute : Attribute, IActionFilter
{
///
/// 辦法執行前
///
///
public void OnActionExecuting(ActionExecutingContext context)
{
//表示假如帶有該屬性,就不停止下面的步骤,直接返回
if (context.ActionDescriptor.EndpointMetadata.Any(item => item.GetType() == typeof(CustomAllowAnonymousAttribute))) //假如標誌的有特殊的記號,就避開檢查;
{
return;
}
Byte[] bytes;
context.HttpContext.Session.TryGetValue("CurrentUser", out bytes);
string cookieKey = CookieSessionHelper.GetCookiesValue(context.HttpContext, "CurrentUser");
string str = cookieKey != null ? new SessionHelper(context.HttpContext).GetSession(cookieKey) : null;
if (string.IsNullOrEmpty(str))
{
var result = new ViewResult { ViewName = "~/Views/SessionLogin/SessionLogins.cshtml" };
//result.ViewData = new ViewDataDictionary(_modelMetadataProvider, context.ModelState);
//result.ViewData.Add("Exception", context.Exception);
context.Result = result; //斷路器---只需對Result赋值--就不繼續往後了;
}
Console.WriteLine("這是辦法執行前");
}
///
/// 辦法執行後
///
///
public void OnActionExecuted(ActionExecutedContext context)
{
if (context.ActionDescriptor.EndpointMetadata.Any(item => item.GetType() == typeof(CustomAllowAnonymousAttribute))) //假如標誌的有特殊的記號,就避開檢查;
{
return;
}
Console.WriteLine("這是辦法執行後");
}
}
空白過濾器,目的是爲了跳過過濾器
public class CustomAllowAnonymousAttribute:Attribute
{
}
在ConfigureServices中添加如下:
services.AddSession();
services.AddMvc(option =>
{
option.Filters.Add(); //全局注册:
option.Filters.Add(); //全局注册異常過濾器:
});
在Configure中添加如下:
app.UseSession();
app.UseCookiePolicy();
還有操作cookie封裝的辦法:
public static class CookieSessionHelper
{
public static void SetCookies(this HttpContext httpContext, string key, string value, int minutes = 30)
{
httpContext.Response.Cookies.Append(key, value, new CookieOptions
{
Expires = DateTime.Now.AddMinutes(minutes)
});
}
public static void DeleteCookies(this HttpContext httpContext, string key)
{
httpContext.Response.Cookies.Delete(key);
}
public static string GetCookiesValue(this HttpContext httpContext, string key)
{
httpContext.Request.Cookies.TryGetValue(key, out string value);
return value;
}
public static CurrentUser GetCurrentUserBySession(this HttpContext context)
{
string sUser = context.Session.GetString("CurrentUser");
if (sUser == null)
{
return null;
}
else
{
CurrentUser currentUser = Newtonsoft.Json.JsonConvert.DeserializeObject(sUser);
return currentUser;
}
}
}
封裝操作Session的
public class SessionHelper
{
private IHttpContextAccessor _accessor;
private ISession _session;
private IRequestCookieCollection _requestCookie;
private IResponseCookies _responseCookie;
public SessionHelper(HttpContext context)
{
_session = context.Session;
_requestCookie = context.Request.Cookies;
_responseCookie = context.Response.Cookies;
}
///
/// 設置session值
///
///
/// 键
/// 值
public void SetSession(string key, string value)
{
var bytes = System.Text.Encoding.UTF8.GetBytes(value);
_session.Set(key, bytes);
}
///
/// 獲取Session值
///
///
///
public string GetSession(string key)
{
Byte[] bytes;
_session.TryGetValue(key, out bytes);
var value = System.Text.Encoding.UTF8.GetString(bytes);
if (string.IsNullOrEmpty(value))
{
value = string.Empty;
}
return value;
}
/////
///// 設置本地cookie
/////
///// 键
///// 值
///// 過時時間
//public void SetCookies(string key,string value,int day = 1)
//{
// _responseCookie.Append(key, value, new CookieOptions
// {
// Expires = DateTime.Now.AddDays(day)
// }) ;
//}
//public void DeleteCookies(string key)
//{
// _responseCookie.Delete(key);
//}
//public string GetCookiesValue(string key)
//{
// _requestCookie.TryGetValue(key, out string value);
// if (string.IsNullOrEmpty(value))
// {
// value = string.Empty;
// }
// return value;
//}
}
