유니티에서 받는 데이터 중  GoogleReceipt data 값 어떤 걸로 넣는지 찾는데 삽질 2시간 OTL....... 



Hash 검증 로직 : node_modules\in-app-purchase\lib\google.js 참고

function validatePublicKey(receipt, pkey, cb) {
    if (!receipt || !receipt.data) {
        return cb(new Error('missing receipt data'));
    }
    if (!pkey) {
        return cb(new Error('missing public key'));
    }
    if (typeof receipt.data !== 'string') {
        return cb(new Error('receipt.data must be a string'));
    }
    var validater = crypto.createVerify('SHA1');
    var valid;
    validater.update(receipt.data);
    try {
        valid = validater.verify(pkey, receipt.signature, 'base64');
    } catch (error) {
        return cb(error);
    }
    if (valid) {
        // validated successfully
        var data = JSON.parse(receipt.data);
        data.status = constants.VALIDATION.SUCCESS;
        return cb(null, data);
    }
    // failed to validate
    cb(new Error('failed to validate purchase'));
}


GooglePublicKey는 해당 어플리케이션 들어가서 확인
