为什么小程序支付成功后并且接受到微信的回调，但是回调里面没有微信的文档参数数据？

准备向小程序统一下单接口发出请求，参数详情为：{"body":"\u7f57\u8299\u52a0-\u62bd\u5956","out_trade_no":"1642564037327916","total_fee":1,"spbill_create_ip":"60.191.90.18","notify_url":"https:\/\/formal.lanchensh.com\/api\/wechat_pay_draw_notify","openid":"ozN0a40H-u_CwYTiaPivDGR4KVOs","appid":"wx156a24e1797fb40a","mch_id":"1603285437","nonce_str":"^J-#gDhRjO98S3-lky61-gmYC$IFM5K$","trade_type":"JSAPI","sign_type":"MD5","sign":"83F6A30AA8619239A397F5DDB711715D"}

微信小程序抽奖方法下单请求结束，返回的结果为：{"return_code":"SUCCESS","return_msg":"OK","result_code":"SUCCESS","mch_id":"1603285437","appid":"wx156a24e1797fb40a","nonce_str":"YJAyiSbA4fWFAS9a","sign":"BEE06958FEC8E350D1E0B8BACABC47DF","prepay_id":"wx1911471737354244d1574e33d071910000","trade_type":"JSAPI"}

微信小程序抽奖支付回调开始，接受参数如下：{"s":"\/\/api\/wechat_pay_draw_notify"}
