微信没升级到新版就会有黑屏，升级了之后画面会变形，我看了论坛不是我的个别现象，好像出现了一段时间了。 微信什么时候能解决呢？

刚开始提示余额不足，然后购买了5万次。再次执行 wx.join1v1Chat，拉起呼叫画面，回调success已执行，屏幕显示 正在等待对方接受邀请，一两秒后 出现提示“呼叫失败”,然后退出了呼叫画面。 被呼叫方 是正常出现了被呼叫画面，点接受进去只能看到本地画面。

文档也太简单了吧 就这么两句话 ******************************************* 调用流程通过 wx.setEnable1v1Chat 接口将用户的接听状态[代码]enable[代码]设置为[代码]true[代码]，该设置仅在当次小程序生命周期有效，小程序每次冷启动后均需要重新设置。通过 wx.join1v1Chat 接口传入呼叫方信息[代码]caller[代码]与接听方信息[代码]listener[代码]发起呼叫，接听方与呼叫方均需在小程序内。****************************************** 到底是发起方如何发起，接听方如何接听呢？先说消息通知这里暂且不提，和组件功能无直接关系。 比如 发起方 执行了 wx.setEnable1v1Chat() ; wx.join1v1Chat( { caller{}, listener{} }) 然后 接听方也执行一遍 wx.setEnable1v1Chat() ; wx.join1v1Chat( { caller{}, listener{} }) 吗? 感觉有些参数好多余，自己发起还要填caller，自己接听也填上listener?

执行 wx.setEnable1v1Chat 一直报 -30002， wechat has no record authorization 打印 授权情况，全都有，请问是什么毛病呢 [图片]

实在检查不出来，请指点，谢谢。 模板如下： ****************************************** 问诊医生 {{name3.DATA}}问诊内容 {{thing1.DATA}}提醒内容 {{thing2.DATA}}****************************************** 发送内容如下： ********************************************** "touser":"oiN1M5MKGaR7B_vv6FktNPFWzoBo", "template_id":"y7VRbJSrV-OqMQRHCUPghgw5YYjsOZTfHGVdfD7AD7s", "page":"tarbar/detail?videoId=25", "miniprogram_state":"trial", "data":{             "name3":{"value":"陈燊"},             "thing1":{"value":"肾结石111"},             "thing2":{"value":"专家已回复，请注意查看"}           } } ********************************************* 响应 如下 ********************************************** { errcode": 47001,   "errmsg": "data format error { ***************************************************

https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/uniform-message/uniformMessage.send.html 两个参数 ，一个小程序 的weapp_template_msg 又说下线了不用发，一个是公众号mp_template_msg 那到底怎么发？？？？？？

我想问一个超级简单的问题，H5里的 a href=xxx?id=xxx在小程序的列表渲染是怎么实现的? 我用navigator吧，navigator内只能放文字，不能放图片等复杂元素，达到点击图片就跳转的效果。 我用 <view bindtap=xxxx > <image>.... </view> 吧，这个bintap 又不知道怎么把id参数放进去

[图片] 之前还很正常，今天突然拉起支付后 短短几秒还没来得及输入支付密码，就退出支付弹出这个界面。

我目前在开发一个排号机，装在一个带打印功能的android设备上，我想用户点击“取号”后 打印 一个张小票出来。 假设打印机已连接安装在设备上，不需要用蓝牙连接什么的，我想简单一点  就用浏览器的web打印功能实现。 当然 打印内容通过js动态生成，不是打印当前整个页面，这个在小程序怎么实现呢？
