dotNET Desktop App

A Dotnet desktop app example for Casdoor.

How to Run the Example

Prerequisites

• dotNET 6 SDK
• WebView2 Runtime (It is usually preinstalled on Windows)

Initialization

The initialization requires 5 parameters, all of which are of type string:

Name	Description	File
Domain	The host/domain of your Casdoor server	CasdoorVariables.cs
ClientId	The Client ID of your Casdoor application	CasdoorVariables.cs
AppName	The name of your Casdoor application	CasdoorVariables.cs
CallbackUrl	The path of the callback URL for your Casdoor application. If not provided, it will be casdoor://callback	CasdoorVariables.cs
ClientSecret	The Client Secret of your Casdoor application	CasdoorVariables.cs

If you do not set these parameters, the project will default to using the Casdoor online demo as the Casdoor server and the Casnode as the Casdoor application.

Running

Visual Studio

1. Open casdoor-dotnet-desktop-example.sln
2. Press Ctrl + F5 to start

Command Line

1. cd src/DesktopApp
2. dotnet run

Preview

After running the dotNET desktop application, a new window will appear on your desktop.

If you click the Casdoor Login button, a login window will appear on your desktop.

After successfully logging in, a user profile window will appear on your desktop, displaying your username.

You can preview the entire process in the GIF image below.

How to Integrate

Opening the Login Window

var login = new Login();
// Triggered when login succeeds, you will receive an auth code in the event handler
login.CodeReceived += Login_CodeReceived;
login.ShowDialog();

Using the Auth Code to Get User Info

public async Task<string?> RequestToken(string clientId, string clientSecret, string code)
{
    var body = new
    {
        grant_type = "authorization_code",
        client_id = clientId,
        client_secret = clientSecret,
        code
    };

    var req = new RestRequest(_requestTokenUrl).AddJsonBody(body);
    var token = await _client.PostAsync<TokenDto>(req);

    return token?.AccessToken;
}

public async Task<UserDto?> GetUserInfo(string token)
{
    var req = new RestRequest(_getUserInfoUrl).AddQueryParameter("accessToken", token);

    return await _client.GetAsync<UserDto>(req);
}

...

var token = await _casdoorApi.RequestToken(
    CasdoorVariables.ClientId,
    CasdoorVariables.ClientSecret,
    authCode
);

var user = await _casdoorApi.GetUserInfo(token);
