PHP 函数版本更新指南：持续集成和自动化

<?php

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;

// 创建带有基本身份验证的 HTTP 客户端
$stack = HandlerStack::create();
$stack->push(GuzzleHttp\Middleware::basicAuth($username, $password));
$client = new Client(['handler' => $stack]);

// 获取函数的最新版本
$response = $client->get('https://<your-domain>/api/functions/<your-function>');

// 提取函数版本
$json = json_decode($response->getBody()->getContents(), true);
$newVersion = $json['version'];

// 检查当前版本是否与最新版本不同
if ($newVersion != $currentVersion) {
  // 部署函数的新版本
  $result = $client->post('https://<your-domain>/api/functions/<your-function>/deploy', [
    'form_params' => ['version' => $newVersion]
  ]);

  // 检查部署是否成功
  if ($result->getStatusCode() == 200) {
    echo "函数部署成功。";
  } else {
    // 部署失败，抛出异常
    throw new RuntimeException("函数部署失败。");
  }
} else {
  echo "函数版本已是最新。";
}

<?php

use GuzzleHttp\Client;
use GuzzleHttp\HandlerStack;

// 获取用户订单
function getTotalAmount($userId)
{
  $client = new Client();

  $response = $client->get('https://<your-domain>/api/orders/' . $userId);
  $orders = json_decode($response->getBody()->getContents(), true);

  // 计算总金额
  $totalAmount = 0;
  foreach ($orders as $order) {
    $totalAmount += $order['amount'];
  }

  return $totalAmount;
}
