请截图说明

请问我里面那里出现发布/分享/交流服务的功能和界面，请截图

在小程序的web-view中获取到公众号的openid以及preperid之后，通过交互返回到小程序中掉起支付。这样可以支付吗？

web-view h5中url跳转后 wx.navigateTo不能用

小程序连接和写入打印机的过程都ok，可是打印机就是没有相应！求解 代码贴出： // 初始化蓝牙适配器   initializeBluetooth: function () { var that = this; if (!wx.openBluetoothAdapter) { console.log('蓝牙适配器打开失败，请检查微信版本或手机是否支持小程序蓝牙模块！') } else { wx.openBluetoothAdapter({ success: function (res) { that.setData({ msg: "初始化蓝牙适配器成功！" }) wx.getBluetoothAdapterState({//获取本机蓝牙适配器状态 success: function (res) { console.log('本机蓝牙适配器状态：') console.log(res) } }) } }) } }, //搜索获取已发现设备   searchBluetooth: function () { var that = this;
