NetCore 使用Session和Cookie

Session

1.在 Startup: ConfigureServices 中添加一下代码

services.AddSession();

2.在 Startup: Configure 中添加一下代码

app.UseSession();

3.正常使用

            var sessionKeyName = "S-KeyName";
            var session = HttpContext.Session.GetString(sessionKeyName);
            if (string.IsNullOrWhiteSpace(session))
            {
                HttpContext.Session.SetString(sessionKeyName, DateTime.Now.ToString("yyyyMMdd-HHmmss"));
                session = HttpContext.Session.GetString(sessionKeyName);
            }

Cookie

1.使用

            var cookieKeyName = "C-KeyName";
            var cookie = HttpContext.Request.Cookies[cookieKeyName];
            if (string.IsNullOrWhiteSpace(cookie))
            {
                cookie = DateTime.Now.ToString("yyyyMMdd-HHmmss");
                HttpContext.Response.Cookies.Append(cookieKeyName, cookie);
            }
