小程序体线上环境，安卓 - 路径为http的图片不能显示,但是ios的却能加载出来呢

我们的小程序需要上报埋点数据给后端，页面加载请求和获取openid的请求都是异步的，当openid获取较慢或者超时的时候，上报的数据就获取不到openid了，这样埋点数据就无法准确区分uv了；另外获取openid的方法偶尔还会异常或者超时，导致我们埋点更加不准确了。。。 各位有没有合适的解决方案

开发app支付，调用v3的统一下单接口，传参如下： {   "appid" : "wx----------c89",  "mchid": "15------1",  "description" :"商品",  "out_trade_no":"ZFCS2021011300000007",  "time_expire": "2021-01-20T11:49:12.841+08:00",  "attach" : "560",  "notify_url" : "http://-------------/app/wx_pay/payNotify.do",  "amount" : {   "total":"1900000",   "currency":"CNY"  } } 返回值确说金额无法映射到对应字段 {"code":"PARAM_ERROR","detail":{"location":"body","value":"1900000"},"message":"无法将 JSON 输入源“/body/amount/total”映射到目标字段“总金额”中，此字段需要一个合法的 64 位有符号整数"} 请问是哪的问题？

要让图片铺满手机宽，要保证图片不失真需要图片至少宽多少px？ 小程序里面图片width:100%,也就是750rpx 但是750rpx，需要多少px？

我们平台的账号体系中有微信登录这个选项获得到了UnionID，也做了相应的保存，现在有了支付以后看到企业付款到零钱需要用到个人apenid，是否有办法通过UnionID获得这个openid，我看有人说可以无障碍获得，这个是如何操作的

jsAPi统一下单成功，js调起支付提示 该订单已过期，请重新下单。没有设置过期时间。
