Program.cs,注意顺序
builder.Services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromMinutes(30);
options.Cookie.HttpOnly = true;
options.Cookie.IsEssential = true;
});//添加session支持
builder.Services.AddDistributedMemoryCache();//添加session支持,同时要加这句
var app = builder.Build();
app.UseSession();//使用session
使用
public class xxController{
private readonly IHttpContextAccessor _httpContextAccessor;
private ISession _session => _httpContextAccessor.HttpContext.Session;
public xxController(IHttpContextAccessor httpContextAccessor){
_httpContextAccessor = httpContextAccessor;
}
public APIResult TestSession(){
if (_session.GetString("errorVcode") != null)
var errorVcode=_session.GetString("errorVcode").ToInt(); //取值
_session.SetString("errorVcode",222);//设值
}
}
