Apply Authorization to All Pages in Blazor

- by mahmood

Program.cs

builder.Services.AddAuthorization(options =>
{
    options.FallbackPolicy = new AuthorizationPolicyBuilder()
        .RequireAuthenticatedUser()
        .Build();
});

builder.Services.ConfigureApplicationCookie(options =>
{
    options.ExpireTimeSpan=TimeSpan.FromDays(14);
    options.SlidingExpiration = true;
    options.Cookie.Name = "BI";
    options.Cookie.HttpOnly = true;
    options.LoginPath = "/Login";
    options.LogoutPath="/Logout";
});

To apply authorization to all pages in Blazor, you have to add:

@attribute [Microsoft.AspNetCore.Authorization.Authorize]

…to your _Imports.razor file.

@attribute [Microsoft.AspNetCore.Authorization.AllowAnonymous]

…on pages that don’t require authorization.

Enable RTL (right-to-left) in Ionic

- by mahmood

Implementing RTL in Ionic 5 apps is very easy. It can be done in two ways

  • Using dir="rtl" attribute in HTML tags
  • Using direction= rtl in css

Using HTML tag

If you want to convert the complete app into RTL layout, then use dir="rtl" on <html> tag itself.

Using CSS at global level

You can also convert the complete app to RTL using CSS in global.scss

:root {
direction: rtl;
}

Install chrony on Ubuntu 22.04

- by mahmood

Chrony is an implementation of the Network Time Protocol (NTP) that runs on Unix-like operating systems (including Linux and macOS) and is released under the GNU GPL v2. It can synchronize the system clock with NTP servers, reference clocks (e.g. GPS receiver), and manual input using wristwatch and keyboard. It can also operate as an NTPv4 (RFC 5905) server and peer to provide a time service to other computers in the network.

apt install -y chrony
timedatectl set-ntp true
systemctl enable chrony && systemctl restart chrony
timedatectl set-timezone Asia/Tehran
chronyc sourcestats -v

Decode JWT Token in ASP.NET Web API

- by mahmood 
var stream = "[encoded jwt]";  
var handler = new JwtSecurityTokenHandler();
var jsonToken = handler.ReadToken(stream);
var tokenS = jsonToken as JwtSecurityToken;

Or, without the cast:

var token = "[encoded jwt]";  
var handler = new JwtSecurityTokenHandler();
var jwtSecurityToken = handler.ReadJwtToken(token);

I can get Claims using:

var jti = tokenS.Claims.First(claim => claim.Type == "jti").Value;
