Ionic

Integra la jornada Human Token en tu aplicación Ionic usando un plugin de Capacitor.

Markdown

La integración usa un plugin local de Capacitor que delega a Custom Tabs en Android y ASWebAuthenticationSession en iOS. Cuando la jornada finaliza, el deep link regresa a través de @capacitor/app.

Requisitos previos

• Ionic con Capacitor v4+
• @capacitor/app instalado
• Xcode 14+ y Android Studio
• Un esquema de URL único para tu aplicación (por ejemplo, myapp)

Paso 1: Definir tu esquema de URL

Elige un esquema único (por ejemplo, myapp). Se usa como callbackUri al crear el proceso:

callbackUri: myapp://callback

Paso 2: Crear la interfaz del plugin de Capacitor

import { registerPlugin } from '@capacitor/core';

export interface UnicoPlugin {
  openSession(options: { url: string }): Promise<{ callbackUrl: string }>;
}

const Unico = registerPlugin<UnicoPlugin>('UnicoPlugin');
export default Unico;

Paso 3: Implementar el plugin de iOS

import Capacitor
import AuthenticationServices

@objc(UnicoPlugin)
public class UnicoPlugin: CAPPlugin, ASWebAuthenticationPresentationContextProviding {
    private var session: ASWebAuthenticationSession?

    @objc func openSession(_ call: CAPPluginCall) {
        guard let urlString = call.getString("url"),
              let url = URL(string: urlString) else {
            call.reject("Invalid URL")
            return
        }

        DispatchQueue.main.async {
            let newSession = ASWebAuthenticationSession(
                url: url,
                callbackURLScheme: "myapp"
            ) { callbackURL, error in
                self.session = nil
                if let callbackURL = callbackURL {
                    call.resolve(["callbackUrl": callbackURL.absoluteString])
                } else {
                    call.reject(error?.localizedDescription ?? "Session cancelled")
                }
            }
            newSession.presentationContextProvider = self
            newSession.prefersEphemeralWebBrowserSession = true
            newSession.start()
            self.session = newSession
        }
    }

    public func presentationAnchor(for session: ASWebAuthenticationSession) -> ASPresentationAnchor {
        guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene,
              let window = windowScene.windows.first else {
            return ASPresentationAnchor()
        }
        return window
    }
}

Paso 4: Implementar el plugin de Android

import android.content.Intent
import android.net.Uri
import androidx.browser.customtabs.CustomTabsIntent
import com.getcapacitor.Plugin
import com.getcapacitor.PluginCall
import com.getcapacitor.PluginMethod
import com.getcapacitor.annotation.CapacitorPlugin

@CapacitorPlugin(name = "UnicoPlugin")
class UnicoPlugin : Plugin() {

    private var pendingCall: PluginCall? = null

    @PluginMethod
    fun openSession(call: PluginCall) {
        val url = call.getString("url") ?: return call.reject("Missing URL")
        pendingCall = call

        activity.runOnUiThread {
            CustomTabsIntent.Builder().build()
                .launchUrl(activity, Uri.parse(url))
        }
    }

    override fun handleOnNewIntent(intent: Intent) {
        super.handleOnNewIntent(intent)
        intent.data?.let { uri ->
            if (uri.scheme == "myapp") {
                pendingCall?.resolve(com.getcapacitor.JSObject().put("callbackUrl", uri.toString()))
                pendingCall = null
            }
        }
    }
}

Paso 5: Configurar los esquemas de URL

iOS

Agrega a Info.plist:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>myapp</string>
        </array>
    </dict>
</array>

Android

Agrega a AndroidManifest.xml dentro de tu <activity> principal:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="myapp" android:host="callback" />
</intent-filter>

Agrega a build.gradle:

implementation("androidx.browser:browser:1.5.0")

Paso 6: Crear el servicio Angular

import { Injectable } from '@angular/core';
import Unico from '../plugins/unico-plugin';

@Injectable({ providedIn: 'root' })
export class UnicoService {
  async openSession(url: string): Promise<string | null> {
    try {
      const result = await Unico.openSession({ url });
      const params = new URL(result.callbackUrl).searchParams;
      return params.get('id');
    } catch {
      return null;
    }
  }
}

Paso 7: Escuchar deep links

En tu AppComponent:

import { App } from '@capacitor/app';

App.addListener('appUrlOpen', (event) => {
  // Handle the callback URL if needed
  console.log('Deep link received:', event.url);
});
