问题描述
我在ASP.NET Core应用程序中设置了MiniProfiler。分析工作正常。
但是,我只希望管理员能够进行个人资料配置。
services.AddMiniProfiler(options =>
{
options.ShouldProfile = request =>
request.HttpContext.User.IsInRole("Admin");
});
问题是,该方法似乎未加载用户身份。User.Identity.Name
属性为null,并且没有声明。
我的猜测是此呼叫是在填充该信息之前发生的?
解决方法
您需要知道,根据the docs,ClaimsPrincipal.IsInRole()
方法会检查类型为ClaimsIdentity.RoleClaimType
的Claims。请确保已添加角色Claims。
这是一个您可以遵循的演示程序:
1。成功注册名称为a@qq.com
的用户。
2。生成角色并向用户添加带有声明的角色:
public async Task CreateRolesandUsers()
{
bool x = await _roleManager.RoleExistsAsync("Admin");
if (!x)
{
// first we create Admin role
var role = new IdentityRole();
role.Name = "Admin";
await _roleManager.CreateAsync(role);
//must add the claim,otherwise IsInRole would always be false..
_roleManager.AddClaimAsync(role,new Claim(ClaimTypes.AuthorizationDecision,"Admin")).Wait();
}
var user = _userManager.FindByNameAsync(User.Identity.Name).Result;
if (user != null)
{
var result1 = await _userManager.AddToRoleAsync(user,"Admin");
}
}
2.Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(
Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<IdentityUser,IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>().AddDefaultUI();
services.AddMiniProfiler(options =>
{
options.RouteBasePath = "/profiler";
options.ShouldProfile = request =>
request.HttpContext.User.IsInRole("Admin");
options.SqlFormatter = new StackExchange.Profiling.SqlFormatters.InlineFormatter();
});
services.AddControllersWithViews();
services.AddRazorPages();
}
public void Configure(IApplicationBuilder app,IWebHostEnvironment env)
{
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication(); //be sure add this
app.UseAuthorization();
app.UseMiniProfiler(); //add this before UseEndpoints
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});
}
结果:
