求高手拆招，unity使用WebGL方式导出，再导入微信小游戏后，编译报错如下： 问题一：来自微信插件plugin.js:74 exception thrown: ReferenceError: AbortController is not defined,ReferenceError: AbortController is not defined     at _JS_WebRequest_Create (http://127.0.0.1:42687/game/webgl.wasm.framework.unityweb.js:3:61167)     at TransportJavaScript::DoRequest(TransportDoRequestArgsProto<HeaderHelper, DownloadHandler, UploadHandler, CertificateHandler, ResponseHelper> const&) (<anonymous>:wasm-function[33276]:0xa4f204)     at UnityWebRequestProto<UnityWebRequestTransport, AtomicRefCounter, RedirectHelper, ResponseHelper, DownloadHandler, UploadHandler, CertificateHandler, HeaderHelper, AsyncOperation>::Task_DoRequest(void*) (<anonymous>:wasm-function[32057]:0xa0b0d3)     at UnityWebRequestProto<UnityWebRequestTransport, AtomicRefCounter, RedirectHelper, ResponseHelper, DownloadHandler, UploadHandler, CertificateHandler, HeaderHelper, AsyncOperation>::Job_ExecuteUnityWebRequest(UnityWebRequestProto<UnityWebRequestTransport, AtomicRefCounter, RedirectHelper, ResponseHelper, DownloadHandler, UploadHandler, CertificateHandler, HeaderHelper, AsyncOperation>*) (<anonymous>:wasm-function[32060]:0xa0b548)     at UnityWebRequestProto<UnityWebRequestTransport, AtomicRefCounter, RedirectHelper, ResponseHelper, DownloadHandler, UploadHandler, CertificateHandler, HeaderHelper, AsyncOperation>::Begin() (<anonymous>:wasm-function[16183]:0x5a4848)     at UnityWebRequest::Begin() (<anonymous>:wasm-function[32071]:0xa0b7f9)     at UnityEngine::Analytics::WebRequestRestClient::PerformPost() (<anonymous>:wasm-function[9787]:0x3297a0)     。。。。。     at n (http://127.0.0.1:42687/game/__dev__/WAGameSubContext.js:1:24431)(env: Windows,mg,1.06.2206090; lib: 2.25.0) plugin.js:74 WebGL: INVALID_OPERATION: drawElements: no valid shader program in use 问题二：来自VM536 WAGameSubContext.js:1 Unhandled promise rejection TypeError: Browser.mainLoop.scheduler is not a function     at Object.resume (webgl.wasm.framework.unityweb.js:3)     at Object.calledMainCb (plugin.js:74)     at callMain (webgl.wasm.framework.unityweb.js:3)     at doRun (webgl.wasm.framework.unityweb.js:3)     at run (webgl.wasm.framework.unityweb.js:3)     at runCaller (webgl.wasm.framework.unityweb.js:3)     at removeRunDependency (webgl.wasm.framework.unityweb.js:3)     at receiveInstance (webgl.wasm.framework.unityweb.js:3)     at receiveInstantiationResult (webgl.wasm.framework.unityweb.js:3)     at VM536 WAGameSubContext.js:1     at n (VM536 WAGameSubContext.js:1)(env: Windows,mg,1.06.2206090; lib: 2.25.0)

db.collection('pois') .aggregate() .lookup({ from: 'requests', let: { id: '$reqId', collect: '$isCollect' }, pipeline: $.pipeline() .match(_.expr($.and([ $.eq(['$reqId','$$id']), $.eq(['$userId','ok']), $.eq(['$$collect', 1]) ]))).done(), as: 'collectList' }) .end() SQL查询内容：pois.reqId 与 requests.reqId关联，且pois.isCollect=1，且requests.userId='ok'， 上述SQL执行后发现：pois.isCollect=1和requests.userId='ok'没有生效，请问如何改写？

查看本地任务管理器，如下图： [图片] 经过实验，发现是首页加入了文字滚动条出现了页面卡顿，CPU飙高的问题。

Page({   data:{     blocks: []   },   watcher:{},   onReady: function () {     let that = this     db.collection('test').where({       reqId: _.eq(reqId)     }).orderBy('isAuthor','desc').get()     .then(res => {       that.setData({         blocks: res.data       })     }).catch(err => {         console.error(err)     })   },   onShow: function () {     console.log('onShow')     this.watcher = db.collection('test').where({       reqId: this.data.reqObj.reqId     }).orderBy('isAuthor','desc').watch({       onChange: function(res){         console.debug(JSON.stringify(res))       },       onError: function(err){ }     })   }, }) [图片] 数据库权限已经开启 [图片] 监听后，操作数据库中的监控数据，小程序端没有任何反应，请问怎么处理？

小程序组件中，组件用来多选，更改this.data.list，组件视图中显示list值，最后将值回调给页面。 当首次打开组件选择，页面能够正常渲染更新，正常回调值返给页面。 但当第二次再打开组件选择，日志中可以看到this.data.list已经被更改，但是组件视图缺没有变化？

1、云函数新增入库数据不含openid_？（同步、异步入库是不是都不含） 2、是否可以在云函数中手动自己加入openid_字段，方便用户在小程序端操作该条记录？

一组数据是从数据库中查出来的，经过用户操作后，是否可以根据主键再批量更新回去？ 除了循环单条更新外，请问有什么好的解决方案？

仿小程序聊天室，可以在页面上看到其他好友的实时消息，是通过什么组件来监控实现的？

打算用云函数做业务处理（异步）逻辑，处理业务时涉及与多个远程接口访问，大概要七八分钟的处理时间。 请问，有什么好的办法解决/优化/规避这一问题？普通请求20秒够了，但我这个要处理上百个接口的数据请求
