之前有转发一则关于google支付服务端验证的文章,今天把之前研究出得服务端订单支付验证代码(PHP版本)贴出来大家分享
在进行服务端交易验证之前,需要到google api consle后台https://console.developers.google.com开通google play developer api并获取请求api证书priket.p12文件;
交易状态API官方文档:https://developers.google.com/android-publisher/api-ref/purchases/products/get
下载google的php版本的官方sdk程序包,然后代码如下:
每次付费成功后,客户端调用计费回调方法可以获取交易的状态:其中会有purchase token和productId(就是在google应用app后台配置的支付商品自定义标示)
请求订单交易状态代码如下:
<?phprequire_once 'Google/Client.php';require_once 'Google/Service/AndroidPublisher.php';//include 'Google/Auth/AssertionCredentials.php';try{$client = new Google_Client();$key_file_location = 'prikey.p12';$key = file_get_contents($key_file_location);$service_account_name = 'xxxxxxxxxxxx-t1280g9vsd7465aprh0xxxxxxxxxxx@developer.gserviceaccount.com';$cred = new Google_Auth_AssertionCredentials( // Replace this with the email address from the client. $service_account_name, // Replace this with the scopes you are requesting. array('https://www.googleapis.com/auth/androidpublisher'), $key);$client->setAssertionCredentials($cred);$service = new Google_Service_AndroidPublisher( $client );$packageName='com.xxxx.xxxx';$productId='9419';$token = 'omoaokhfkmiipfffmemjaclh.AO-J1OyFcurjPmcY4J5MFMYvW5z6jq-X9SrpZCo93etscPe0SzDItMnAY50RLWLwOEYl71HQEBXG8fREgJp-EVZTOwkG8uHuKf3UPlx0u8rwK7Qw4bRE9SI';$optps=array();$resp = $service->purchases_products->get( $packageName, $productId, $token, $optps );$resp = (array)$resp;var_dump($resp);}catch(Exception $e){ echo $e->getCode(),'|',$e->getMessage();}?>
如果正常的话,api会相应关于该次交易的状态,相应的字段说明见官方文档:https://developers.google.com/android-publisher/api-ref/purchases/products#resource
consumptionState:商品消费状态,0表还未消费,1表消费了(因为google的同一个商品未消费的话是不允许重复购买的)
developerPayload:这个比较重要,是我们开发者自定义透传的,一般为自身系统订单号之类的交易唯一标示,可以用来比对
purchaseState:购买状态,1代表购买了,0代表取消
备注:貌似这个api调用google平台有20w/日的次数限制
