https://developers.weixin.qq.com/miniprogram/dev/wxcloud/reference-sdk-api/database/command/aggregate/AggregateCommand.html 请问 $.pipeline() 这个属于聚合操作符吗？为什么只在示例中见到，文档却没能找到介绍？

[图片] 想跳转到对应的专题服务，使用云开发，如何使用呢？ 求教代码示例。

https://developers.weixin.qq.com/miniprogram/dev/wxcloudrun/src/quickstart/custom/node.html 做为一个前端，想使用egg.js做后端接口，写代码都没问题，部署整闷了。怎么弄都不成功！ 看教程说复制这一段可以交流，这一段能看出个啥呢？ wx3c8406171c9106a1 pldataprod-1ghwo42v0d4b4041 tid=211275 rid=multi_tenant_1pmvmaYPuFeFjK pldataeggjs bid=31293599 pldataeggjs-004

我想使用 egg.js + MySQL 做后端，但是部署不知道选择哪个了？请教：微信云托管、腾讯云、 Serverless，这三个是什么关系呢？

https://developers.weixin.qq.com/miniprogram/dev/api/media/audio/InnerAudioContext.onError.html innerAudioContext.onError((err) => { console.log(err.errCode); }) 无法打印。onError，不起作用。

https://developers.weixin.qq.com/miniprogram/dev/reference/api/Page.html 建议将 onShareTimeline 和 onShareAppMessage 的 title 默认值 当前小程序名称 改成 “当前页面名称” 即 wx.setNavigationBarTitle 所设置的名称。

使用了两个音频地址测试 seek 跳转： // 此地址可以正常跳转 有效： // http://sp.9sky.com/convert/song/music/1030028/20210721151849987.mp3 // 此地址跳转会从头开始播放 无效： // https://www.prehot.com/test/audio.mp3 使用的代码： const _InnerAudioContext = wx.createInnerAudioContext() _InnerAudioContext.autoplay = true Page({   data: {   },   onLoad: function (options) {     _InnerAudioContext.src = 'http://sp.9sky.com/convert/song/music/1030028/20210721151849987.mp3'     _InnerAudioContext.onTimeUpdate(() => {       console.log(_InnerAudioContext.currentTime);     })   },   forward: function () {     _InnerAudioContext.pause() // 先暂停     _InnerAudioContext.seek(31) // 再跳转     setTimeout(() => {       _InnerAudioContext.play()     }, 500); // 给一个延迟，再播放   } }) 求教，是不是自己的服务器配置有问题？windows iis7 谢谢！

如图：快速切换到不同的编辑器中，以前 vs 就有这个功能。 [图片]

const InnerAudioContext = wx.createInnerAudioContext(); InnerAudioContext.autoplay = true; InnerAudioContext.src = 'cloud://xxxxxx/不存在的音频文件地址.mp3' 如果播放的音频文件不存在，如何判断呢？ 使用了.onError() 监听，没有反应： onLoad: function (options) { InnerAudioContext.onError(err => { console.log(err); }) }, 谢谢！
