Iniciando

Passo 1: Criar um Aplicativo MAUI

Crie seu Aplicativo MAUI.

Passo 2: Adicionar uma Referência

Adicione uma referência ao Casdoor.MauiOidcClient no seu projeto.

Passo 3: Adicionar o Cliente Casdoor

Adicione CasdoorClient como um singleton nos serviços.

builder.Services.AddSingleton(new CasdoorClient(new()
{
Domain = "<your domain>",
ClientId = "<your client>",
Scope = "openid profile email",

#if WINDOWS
RedirectUri = "http://localhost/callback"
#else
RedirectUri = "casdoor://callback"
#endif
}));

Passo 4: Projetar a UI

Adicione código ao arquivo MainPage.

MainPage.xaml

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Casdoor.MauiOidcClient.Example.MainPage">

<ScrollView>
<VerticalStackLayout>

<StackLayout
x:Name="LoginView">
<Button
x:Name="LoginBtn"
Text="Log In"
SemanticProperties.Hint="Click to log in"
Clicked="OnLoginClicked"
HorizontalOptions="Center" />

<WebView x:Name="WebViewInstance" />
</StackLayout>

<StackLayout
x:Name="HomeView"
IsVisible="false">

<Label
Text="Welcome to .NET Multi-platform App UI"
SemanticProperties.HeadingLevel="Level2"
SemanticProperties.Description="Welcome to dot net Multi-platform App UI"
FontSize="18"
HorizontalOptions="Center" />

<Button
x:Name="CounterBtn"
Text="Click me"
SemanticProperties.Hint="Counts the number of times you click"
Clicked="OnCounterClicked"
HorizontalOptions="Center" />

<Label
x:Name="NameLabel"
Text=""
SemanticProperties.HeadingLevel="Level2"
SemanticProperties.Description="User's name"
FontSize="18"
HorizontalOptions="Center" />

<Label
x:Name="EmailLabel"
Text=""
SemanticProperties.HeadingLevel="Level2"
SemanticProperties.Description="User's email"
FontSize="18"
HorizontalOptions="Center" />

<Button
x:Name="LogoutBtn"
Text="Log Out"
SemanticProperties.Hint="Click to log out"
Clicked="OnLogoutClicked"
HorizontalOptions="Center" />

</StackLayout>
</VerticalStackLayout>
</ScrollView>

</ContentPage>

MainPage.cs

namespace Casdoor.MauiOidcClient.Example
{
public partial class MainPage : ContentPage
{
int count = 0;
private readonly CasdoorClient client;
private string accessToken;
public MainPage(CasdoorClient client)
{
InitializeComponent();
this.client = client;

#if WINDOWS
client.Browser = new WebViewBrowserAuthenticator(WebViewInstance);
#endif
}

private void OnCounterClicked(object sender, EventArgs e)
{
count++;

if (count == 1)
CounterBtn.Text = $"Clicked {count} time";
else
CounterBtn.Text = $"Clicked {count} times";

SemanticScreenReader.Announce(CounterBtn.Text);
}

private async void OnLoginClicked(object sender, EventArgs e)
{
var loginResult = await client.LoginAsync();
accessToken = loginResult.AccessToken;
if (!loginResult.IsError)
{
NameLabel.Text = loginResult.User.Identity.Name;
EmailLabel.Text = loginResult.User.Claims.FirstOrDefault(c => c.Type == "email")?.Value;

LoginView.IsVisible = false;
HomeView.IsVisible = true;
}
else
{
await DisplayAlert("Error", loginResult.ErrorDescription, "OK");
}
}

private async void OnLogoutClicked(object sender, EventArgs e)
{
var logoutResult = await client.LogoutAsync(accessToken);


if (!logoutResult.IsError)
{
HomeView.IsVisible = false;
LoginView.IsVisible = true;
this.Focus();
}
else
{
await DisplayAlert("Error", logoutResult.ErrorDescription, "OK");
}
}
}
}

Passo 5: Suporte à Plataforma Android

Modifique o arquivo AndroidManifest.xml.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true"></application>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<queries>
<intent>
<action android:name="android.support.customtabs.action.CustomTabsService" />
</intent>
</queries>
</manifest>

Passo 6: Lançar o Aplicativo
