用 composer 安装生成 WSDL 所需的库
composer require piotrooo/wsdl-creator
实现用于外部访问的入口文件,代码示例请参考(其中方法名和参数中出现的 Notify 对应一个类名,该类的方法将成为可以通过 SOAP 调用的外部接口):
<?phpuse WSDL\DocumentLiteralWrapper;use WSDL\WSDLCreator;use WSDL\XML\Styles\DocumentLiteralWrapped;class Api{ public static function soapNotify() { $host = $_SERVER['HTTP_HOST']; $soapuri = "http://{$host}/Api/soapNotify"; if (isset($_GET['wsdl'])) { $wsdl = new WSDLCreator('Notify', $soapuri); $wsdl->renderWSDL(); exit; } $server = new SoapServer(null, [ 'uri' => $soapuri ]); $server->setClass('Notify'); $server->handle(); }}
实现包含接口功能逻辑的类文件,代码示例请参考(其中方法的注释相当重要,是 wsdl-creator 正确生成 WSDL 的依据,必须严格按照格式进行注释):
class Notify{ /** * @desc sendText 向患者的微信发送文本信息 * @param string $toUser 发给哪个用户 * @param string $content 发送的内容 * @return string $result */ public function sendText($toUser, $content) { if (!$toUser || !$content) { return E::INVALID; } $user = G::xpdo()->row("SELECT * FROM `users` WHERE `patientid` = ?", [$toUser]); if (!$user) { return E::NODATA; } $api = G::xpdo()->row("SELECT * FROM `api` WHERE `token` = ?", [$user['token']]); $weixin = new Weixin($api['appid'], $api['appsecret']); $weixin->sendText($user['openid'], $content); return 0; }}
使用 SoapUI 软件对接口进行调试
编制相应的接口调用说明文档
