wop-platform / wop-php-sdk example snippets
use Wop\Sdk\WopClient;
use Wop\Sdk\WopConfig;
use Wop\Sdk\Transport\CurlTransport;
$client = new WopClient(new WopConfig(
appKey: 'app_10012481831',
securityReq: 'WOP-RSA3072-SHA256',
privateKey: $merchantPrivateKeyPemOrBase64, // 己方私钥（出向加签 / 入向 DEK 解包）
peerPublicKey: $platformPublicKeyPemOrBase64, // 平台公钥（响应/回调验签 / DEK 包装）
));
// 1. 构造请求（L0 明文 / L2 数字信封），得到可直接发送的 RequestDraft
$draft = $client->buildRequest('POST', '/gateway/logistics.order.query', $jsonBody, 'L2');
// 2. 任选 Transport 发送（curl 扩展适配器 / Guzzle peer 适配器，或自带 HTTP 栈）
$transport = new CurlTransport();
$response = $transport->send($draft->method, 'https://gateway.example.com' . $draft->path,
$this->toHeaderLines($draft->headers), $draft->wireBody);
// 3. 验证平台响应（验签 → digest 复核 → DEK 解包 → alg 族比对 → 解密，顺序固定）
$result = $client->verifyResponse(
$this->toArray($response->headers), $response->body, '/gateway/logistics.order.query');
if ($result->ok) {
$plaintext = $result->plaintext;
