建议按照接口文档进行开发,不要直接使用sdk
下面贴上代码为大家一一介绍文档和真实情况的差距:

require './common/payConfig.php';
$key = $payConfig['key'];
$orderData = array(
    	"appid"            =>   $payConfig['appid'],
	'mch_id'           =>   $payConfig['mchid'],
	'sub_appid'        =>   $payConfig['sub_appid'],
	'sub_mch_id'       =>   $mchid,
	'body'             =>   $body,
	'attach'           =>   $attach,
	'out_trade_no'     =>   $order_id,
	'total_fee'        =>   $total_price,
	'spbill_create_ip' =>   $_SERVER['REMOTE_ADDR'],
	'notify_url'       =>   'daichongweb.com',
	'trade_type'       =>   'JSAPI',
	// 'openid'        =>   $UnionID, 这个是不需要的
	'goods_tag'        =>   'daichong',
	'nonce_str'        =>   $this->getNonceStr(),
	'sub_openid'       =>   $mini_openid
);
ksort($orderData);
reset($orderData);
$buff = "";
foreach ($orderData as $k => $v)
{
   if($k != "sign" && $v != "" && !is_array($v)){
      $buff .= ($k . "=" . $v . "&");
   }
}
$buff = trim($buff, "&");
$buff = $buff.'&key='.$key;
$signA = strtoupper(MD5($buff));
$orderData['sign'] = $signA;

$xml = $this->arrayToXml($orderData);

$url = "https://api.mch.weixin.qq.com/pay/unifiedorder";
        
$result = $this->https_post($url,$xml);
$payArray = (array)simplexml_load_string($result, 'SimpleXMLElement', LIBXML_NOCDATA);
