# Annunci interstitial a pagina intera nelle applicazioni a pagina singola

Questa guida mostra come implementare **Interstitiale a pagina intera (FPI)** gli annunci in una Single Page Application (SPA) usando chiamate API dirette. Funziona con React, Vue, Angular e altri framework.

## Implementazione passo dopo passo

{% stepper %}
{% step %}

### Imposta lo stato del componente

Per prima cosa, crea variabili di stato per tenere traccia del tuo sistema pubblicitario e della navigazione:

```typescript
'use client'

import { useEffect, useState } from 'react'

export default function HomePage() {
  const [adLoaded, setAdLoaded] = useState(false)
  const [currentPage, setCurrentPage] = useState('home')

  useEffect(() => {
    setAdLoaded(true)
    console.log('✅ Metodo API FPI inizializzato')
  }, [])
}
```

{% endstep %}

{% step %}

### Crea la funzione di richiesta API

Questa funzione effettua una richiesta HTTP diretta al server pubblicitario FPI:

```typescript
const triggerFPIAd = async () => {
  console.log('🎯 Eseguo una chiamata API diretta al servizio FPI...')

  try {
    // Prepara la richiesta con il contesto dell'utente
    const requestBody = {
      user: {
        ua: navigator.userAgent,
        language: navigator.language || 'en-US',
        referer: window.location.href,
        consumer: 'ad-provider',
        gdpr: { gdpr: 0 },
        screen_resolution: `${screen.width}x${screen.height}`,
        window_orientation: screen.width > screen.height ? 'landscape' : 'portrait',
        cookies: [],
        scr_info: btoa('async||3')
      },
      zones: [{
        custom_targeting: {},
        id: 1234567, // Il tuo ID zona FPI (usa l'ID zona FPI mobile per i dispositivi mobili)
        extra_params: {
          first_request: true,
          zone_type: 35 // Formato interstitial
        }
      }]
    }

    // Effettua la chiamata API
    const response = await fetch('https://s.pemsrv.com/v1/api.php', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(requestBody)
    })

    if (!response.ok) {
      throw new Error(`Errore HTTP! stato: ${response.status}`)
    }

    const data = await response.json()
    console.log('📥 Risposta API completa:', data)

    // Elabora la risposta
    if (data.zones && data.zones.length > 0) {
      const zone = data.zones[0]
     
      if (zone.data) {
        console.log('🎨 Visualizzo l'annuncio...')
        await displayInterstitialAd(zone.data)
      } else {
        console.log('❌ Nessun dato dell'annuncio nella risposta')
      }
    }

  } catch (error) {
    console.error('❌ Errore API FPI:', error)
  }
}
```

{% endstep %}

{% step %}

### Crea la funzione di visualizzazione

Questa funzione gestisce più formati di annunci

```typescript
const displayInterstitialAd = async (adData: any) => {
  console.log('🎨 Inizio a visualizzare l'annuncio interstitial...')

  try {
    // Rimuovi qualsiasi overlay esistente
    const existingOverlay = document.getElementById('fpi-interstitial-overlay')
    if (existingOverlay) {
      document.body.removeChild(existingOverlay)
    }

    // Crea un overlay a schermo intero
    const overlay = document.createElement('div')
    overlay.id = 'fpi-interstitial-overlay'
    overlay.style.cssText = `
      position: fixed;
      top: 0;
      left: 0;
      width: 100vw;
      height: 100vh;
      background-color: rgba(0, 0, 0, 0.9);
      z-index: 999999;
      display: flex;
      align-items: center;
      justify-content: center;
    `

    // Crea il contenitore dell'annuncio
    const adContainer = document.createElement('div')
    adContainer.style.cssText = `
      position: relative;
      width: 100vw;
      height: 100vh;
      background: white;
      overflow: hidden;
    `

    // Crea il pulsante di chiusura
    const closeButton = document.createElement('button')
    closeButton.innerHTML = '✕'
    closeButton.style.cssText = `
      position: absolute;
      top: 10px;
      right: 10px;
      width: 40px;
      height: 40px;
      border: none;
      background: rgba(0, 0, 0, 0.7);
      color: white;
      font-size: 20px;
      border-radius: 50%;
      cursor: pointer;
      z-index: 1000000;
    `

    closeButton.onclick = () => {
      document.body.removeChild(overlay)
      console.log('🚪 Annuncio interstitial chiuso')
    }

    // Determina il formato dell'annuncio e crea il contenuto
    let adContent = ''

    // Formato 1: annuncio iframe
    if (adData.html && adData.html.includes('iframe.php')) {
      adContent = `
        <iframe
          src="${adData.html}"
          width="100%"
          height="100%"
          frameborder="0"
          allowfullscreen
          sandbox="allow-scripts allow-forms allow-popups"
          style="width: 100vw; height: 100vh; border: none;"
        ></iframe>
      `
      console.log('🖼️ Creato annuncio iframe')
    }

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.exoclick.com/tutorials/it/tutorial/tutorial-per-publisher/fpi-spa-with-exoclick.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
