综合信息门户与代理价：技术实现与应用

<?php

// 假设我们有一个代理服务类，用于处理数据传输

class ProxyService {

public function fetchData($url) {

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$data = curl_exec($ch);

curl_close($ch);

return $data;

}

public function sendData($url, $data) {

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);

curl_close($ch);

return $response;

}

}

// 创建一个信息门户类，用于整合来自不同源的数据

class InfoPortal {

private $proxy;

public function __construct(ProxyService $proxy) {

$this->proxy = $proxy;

}

public function fetchAllData() {

$urls = [

'http://example.com/data1',

'http://example.com/data2'

];

$allData = [];

foreach ($urls as $url) {

$data = json_decode($this->proxy->fetchData($url), true);

$allData = array_merge($allData, $data);

}

return $allData;

}

}

// 使用示例

$proxy = new ProxyService();

$portal = new InfoPortal($proxy);

$data = $portal->fetchAllData();

print_r($data);
