前端唤醒支付的参数如下:
{
"appId": "wx07a0818e64b92446",
"nonceStr": "CD8hMJ5bxgIUfEv3IVLsqGoI9jVEKdBQ",
"package": "Sign=WXPay",
"partnerId": "1233191102",
"prepayId": "wx0315024772242869f581e8f36b45b30000",
"sign": "50FBC6C4772E9E125B2B23DF6B97AAE3",
"timeStamp": "1667458967",
"tradeNo": "1588064126349393920"
}
该问题可能是以下两个原因:
1、统一下单接口中上传的appid与调起微信客户端进行支付的appid不一致
2、调起微信客户端进行支付的必要参数prepayid有误或者prepayid已经过期(有效期2小时)
appid不一致或者prepayid过期了
