1.　　用户登录时，将用户的权限写入Cookie；

1 //将需要的信息写入claims后
2 var identity = new ClaimsIdentity(claims, IdentityConstants.ApplicationScheme);
3 var userPrincipal = new ClaimsPrincipal(identity);
4 await HttpContext.SignInAsync(IdentityConstants.ApplicationScheme, userPrincipal);

2.　　View中，利用bootstraptreeview显示菜单，使用User.IsInRole等判断是否有相关权限，进而确定是否需要显示该部分的菜单

//部分代码
<div ></div>
<script>
    var tree = new Array();
    @if (User.IsInRole("**")||(User.HasClaim("单位","***")&&User.IsInRole("部门管理员")))
    {
        <text>
            tree.push({
                text: "***",
                selectable: false,
                nodes:
                    [
                        {
                            text: "***",
                            selectable: false,
                            nodes:
                                [
                                    {
                                        text: "***",
