回调地址必须是域名吗？现在使用的是ip，但是接收不到回调

time_expire -> 20201226052638 time_start -> 20201226045638 错误提示time_expire时间过短，刷卡至少1分钟，其他5分钟 开始时间4点56，结束时间5点26，为什么还是提示时间过短？

<xml> <appid>wxa5b52c******b12d</appid> <mch_id>1541******</mch_id> <nonce_str>1549346721</nonce_str> <sign><![CDATA[139AF00B5A51445938695E42EC371C77]]></sign> <sign_type>MD5</sign_type> <transaction_id>160896557147*****289</transaction_id> </xml> 还缺啥？

创建订单后取消支付，接下来再用此订单号调用统一下单接口会出现订单号重复的错误，如果我想继续使用这个订单号再次发起支付该如何处理

使用接口https//api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=SECRET&js_code=JSCODE&grant_type=authorization_code获取的openid在调用 https//api.weixin.qq.com/cgi-bin/express/business/order/add?access_token=ACCESS_TOKEN作为openid的参数传入 为什么会返回openid无效的错误 {"errcode":40003,"errmsg":"invalid openid rid: 5fbb17f9-51271919-5dec0382"}

{"errcode":40003,"errmsg":"invalid openid rid: 5fb62d96-313b33f2-68b54927"} openid无效 请求参数 {"add_source":0,"biz_id":"0","cargo":{"space_y":1,"space_z":1,"detail_list":[{"name":"测试商品4","count":4}],"count":1,"weight":1.0,"space_x":1},"delivery_id":"YTO","expect_time":1605783116,"insured":{"use_insured":0,"insured_value":0},"openid":"o6jg641Z8d6CTLZCij4LYzx1-tOg","order_id":"1","receiver":{"area":"","address":"","province":"","city":""},"sender":{"area":"111111","country":"11111","address":"1111","province":"1111","city":"1111","post_code":"11111","name":"测试","mobile":"111111","company":"11111"},"service":{"service_type":0,"service_name":"普通快递"},"shop":{"goods_name":"测试商品4","img_url":"img_url","wxa_path":"wxa_path","goods_count":4}} openid通过接口获取的，直接用就无效了

支付后，回调接口如果不通知微信支付成功，支付的金额是退回支付账号，还是如何处理

在后台编译保存到数据库中的图文消息，如何让每个进入公众号的用户都能看的到，不需要用户操作直接就能展示出来，应该去调用哪个接口？
