PHP implements the verification example code of apple API in-app purchase voucher

The following is the server-side verification of AppStore in-app purchases. The payment process in the app is completed by the IOS programmer. After the payment is completed, the front-end will obtain the corresponding payment. Voucher, then it is necessary to verify whether the payment was actually made based on the voucher, and then complete the business logic of subsequent product functions. As for verification, there are two types: one is to verify by the front end itself, and the other is to verify through the back end. It can be imagined that most of them will be verified through the backend, so the real sword is shown below:

1. (Encapsulated credential acquisition structure class, the tp framework is used here , it is also very convenient to modify other frameworks here. If you don’t understand, you can leave me a message)

/**
 * 苹果内购Api查询接口
 * Class AppleAipController
 * @package Pay\Controller
 */class  AppleAipController extends  Controller{

    /**
     * @var string
     */
    private $sandboxCurl = "https://sandbox.itunes.apple.com/verifyReceipt";    private $formalityCurl = "https://buy.itunes.apple.com/verifyReceipt";    /**
     * @return array
     */
    public function send($encodeStr,$sandboxStatus=0)
    {
        $ch = curl_init();        $data['receipt-data'] =$encodeStr;        $encodeStr =  json_encode($data);        $url = $sandboxStatus?($this->formalityCurl):($this->sandboxCurl);
        curl_setopt($ch, CURLOPT_URL,$url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        // post数据
        curl_setopt($ch, CURLOPT_POST, 0);        // post的变量
        curl_setopt($ch, CURLOPT_POSTFIELDS, $encodeStr);
        curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);        $output = curl_exec($ch);
        curl_close($ch);        $resut = (Array)json_decode($output,true);        return $resut;
    }
}

2. Because the product design of the company involves financial issues, it is best to be cautious, so before The written token and signature verification are now in effect. If you need to know about the implementation of signature verification and token, you can take a look here.

Please click on the signature verification article, and please click on the token article

Then I will also assign my calling method below, because it is used on tp. If you need to use other frameworks or native ones, you can leave me a message to help modify it. I will attach my calling code below:
