单页应用中的全页插页式广告

本指南演示如何实现 全屏插页广告（FPI） 在单页应用（SPA）中使用直接 API 调用的广告。适用于 React、Vue、Angular 及其他框架。

逐步实现

1

设置组件状态

首先，创建状态变量来跟踪你的广告系统和导航：

'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('✅ FPI API 方法已初始化')
  }, [])
}

2

创建 API 请求函数

此函数向 FPI 广告服务器发起直接 HTTP 请求：

const triggerFPIAd = async () => {
  console.log('🎯 正在向 FPI 服务发起直接 API 调用...')

  try {
    // 使用用户上下文准备请求
    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, // 你的 FPI 区域 ID（移动设备使用移动端 FPI 区域 ID）
        extra_params: {
          first_request: true,
          zone_type: 35 // 插页格式
        }
      }]
    }

    // 发起 API 调用
    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(`HTTP error! status: ${response.status}`)
    }

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

    // 处理响应
    if (data.zones && data.zones.length > 0) {
      const zone = data.zones[0]
     
      if (zone.data) {
        console.log('🎨 正在展示广告...')
        await displayInterstitialAd(zone.data)
      } else {
        console.log('❌ 响应中没有广告数据')
      }
    }

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

创建显示函数

此函数处理多种广告格式

const displayInterstitialAd = async (adData: any) => {
  console.log('🎨 开始展示插页广告...')

  try {
    // 移除任何现有覆盖层
    const existingOverlay = document.getElementById('fpi-interstitial-overlay')
    if (existingOverlay) {
      document.body.removeChild(existingOverlay)
    }

    // 创建全屏覆盖层
    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;
    `

    // 创建广告容器
    const adContainer = document.createElement('div')
    adContainer.style.cssText = `
      position: relative;
      width: 100vw;
      height: 100vh;
      background: white;
      overflow: hidden;
    `

    // 创建关闭按钮
    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('🚪 插页广告已关闭')
    }

    // 确定广告格式并创建内容
    let adContent = ''

    // 格式 1：iframe 广告
    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('🖼️ 已创建 iframe 广告')
    }

点击展开更多广告格式

    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('🖼️ 已创建 iframe 广告')
    }
   
    // 格式 2：视频广告
    else if (adData.video) {
      const hasClickUrl = adData.url && adData.url.trim() !== ''

      if (hasClickUrl) {
        // 带点击跳转的视频
        adContent = `
          <div style="position: relative; width: 100vw; height: 100vh; cursor: pointer;"
               onclick="window.open('${adData.url}', '_blank')">

添加触发按钮

return (
  <div>
    <h1>我的页面</h1>
    <button onClick={triggerFPIAd}>
      加载 FPI 广告
    </button>
  </div>
)
