浙公网安备33032602100516微信支付统一下单，用PHP怎么实现？（代码全）
阅读 23145 · 发布日期 2020-08-24 17:26 · 温州优光网络科技有限公司|建站|APP小程序制作|做网站SEO推广优化
H5支付时出现“签名错误”怎么办？注意调用微信“统一下单”接口后返回pre_pay_id后，需要用户再次进行签名返回给HTML； “支付目录没有授权”，进入微信商家管理后台设置即可。
一、Model层，Wxpay.php
class Wxpay
{
private $appid = '
wxe8*****d4'
;
//微信公众号appid
private $secret = '
37c4*******5f0'
;
//微信公众号appsecret
private $mchid = '
13******02'
;
//商家号
private $key = '
5363e******49e8'
;
//支付密钥
private $sslcert_path = '
apiclient_cert.pem'
;
//证书所在绝对路径
private $sslkey_path = '
apiclient_key.pem'
;
//证书所在绝对路径
public function __construct($appid = '
'
, $secret = '
'
, $mchid = '
'
, $key = '
'
)
{
if(!empty($appid)) $this->appid = $appid;
if(!empty($secret)) $this->secret = $secret;
if(!empty($mchid)) $this->mchid = $mchid;
if(!empty($key)) $this->key= $key;
}
