抖音小程序調起支付寶支付php微擎代碼和HTML代碼
內部訂單號生成後，下一步調支付寶支付。內部訂單號沒有成功的看https://blog.csdn.net/weixin_37616043/article/details/102951581。
下面php代碼：
$paramList= array('out_trade_no' => $outTradeNo, 'total_amount' => $orderInfo['money'], 'subject' =>$orderName, 'body' => $bodyName . ':0:TTAPP');
$sec = pdo_fetch('select * from ' . tablename('ewei_shop_sysset') . ' where uniacid=:uniacid limit 1', array(':uniacid' => 59));
$sec = iunserializer($sec['sec']);
$alipay_config = $sec['app_alipay'];
if (!empty($alipay_config)) {
$reNews = $this->alipay_build($paramList, $alipay_config);
$alipay = array('success' => true, 'payinfo' => $reNews);//生成調起支付寶url
}
$params=array();
$params['app_id']=$this->appId;
$params['sign_type']='MD5';
$params['out_order_no']=$out_order_no;//抖音小程序內部生成的訂單號
$params['merchant_id']=$this->merchant_id;
$params['timestamp']=strval(time());
$params['product_code']='pay';
$params['payment_type']='direct';
$params['total_amount']=$totalFee*100;
$params['trade_type']='H5';
$params['uid']=$openid;
$params['version']='2.0';
$params['currency']='CNY';
$params['subject']=$orderName;
$params['body']=$bodyName;
$params['trade_time']=strval($requestConfigs['trade_time']);
$params['valid_time']='300';
$params['notify_url']=$this->root .'payment/alipay/notify.php';
$params['alipay_url']=!empty($alipay['success'])?$alipay['payinfo']:'';
$params['wx_type']='';
$params['wx_url']='';
$oplist=$this->getSignContent($params , $dataList['charset'] ,$this->Key);
$params['sign']=md5($oplist);
return $params;//返回前端數據
public function alipay_build($params, $config = array()){
global $_W;
$arr = array('app_id' => $config['appid'], 'method' => 'alipay.trade.app.pay', 'format' => 'JSON', 'charset' => 'utf-8', 'sign_type' => 'RSA2', 'timestamp' => date('Y-m-d H:i:s', time()), 'version' => '1.0', 'notify_url' => $_W['siteroot'] .

ksort($arr);
$string1 = '';
foreach ($arr as $key => $v )
{
if (empty($v))
{
continue;
}
$string1 .= $key . '=' . $v . '&';
}
$string1 = rtrim($string1, '&');
$pkeyid = openssl_pkey_get_private($this->chackKey($config['private_key_rsa2'], false));
if ($pkeyid === false)
{
return error(-1, '提供的私鑰格式不對');
}
$signature = '';
openssl_sign($string1, $signature, $pkeyid, OPENSSL_ALGO_SHA256);
openssl_free_key($pkeyid);
$signature = base64_encode($signature);
$arr['sign'] = $signature;
return http_build_query($arr);
}
public function chackKey($key, $public = true)
{
if (empty($key)) {
return $key;
}
if ($public) {
if (strexists($key, '-----BEGIN PUBLIC KEY-----')) {
$key = str_replace(array('-----BEGIN PUBLIC KEY-----', '-----END PUBLIC KEY-----'), '', $key);
}
$head_end = '-----BEGIN PUBLIC KEY-----
{key}
-----END PUBLIC KEY-----';
}
else {
if (strexists($key, '-----BEGIN RSA PRIVATE KEY-----')) {
$key = str_replace(array('-----BEGIN RSA PRIVATE KEY-----', '-----END RSA PRIVATE KEY-----'), '', $key);
}
$head_end = '-----BEGIN RSA PRIVATE KEY-----
{key}
-----END RSA PRIVATE KEY-----';
}
$key = str_replace(array('
', '
', '
'), '', trim($key));
$key = wordwrap($key, 64, '
', true);
return str_replace('{key}', $key, $head_end);
}
HTML代碼：
tt.pay({
orderInfo: e.data,
service: 4,
_debug:1,
getOrderStatus(res) {
console.log(res)
},
success(res) {
console.log('成功',res)
if (res.code == 0) {
// 支付成功處理邏輯，只有res.code=0時，才表示支付成功
// 但是最終狀態要以商戶後端結果爲準
}
},
fail(res) {
console.log('失敗',res)
// 調起收銀臺失敗處理邏輯
}
這是我返回前端數據：
有問題大家一起交流。
