微信支付下单相关的接口 createOrder 怎么获取到 prepay_id，能否把 createOrder 和 getPayInfo 解耦？ #3560

  WxPayUnifiedOrderV3Result.JsapiResult wxPayMpOrderResult = wxPayService.createPartnerOrderV3(TradeTypeEnum.JSAPI, request);

    public static class JsapiResult implements Serializable {
        private static final long serialVersionUID = 4465376277943307271L;
        private String appId;
        private String timeStamp;
        private String nonceStr;
        private String packageValue;
        private String signType;
        private String paySign;
}
