为什么微信小程序录音recorderManager.onFrameRecorded((res)=>正常录音和获取数据，但是在同声同译的recordRecognition.start({lang: "zh_CN", duration: 2560});后，就再也触发不了onFrameRecorded，如何解决？同声同译的start同时也能onFrameRecorded获取数据做人声简易判断mffc。如果停止mffc获取数据转start同声同译，这样可以误判，可以随时cancle同声同译。现在本地record是recorderManager.start({format:"pcm",sampleRate:16000,frameSize:0.3,numberOfChannels:1,duration:60000});，请问是不是sampleRate:16000,frameSize:0.3与同声同译一样就可以保证同步onFrameRecorded获取数据，那么同声同译的sampleRate:16000,frameSize:0.3参数又是多少？麻烦给建议，谢谢。如果单独只是执行同声同译start后如何保证onFrameRecorded获取数据？谢谢。

微信跑一个worder的简单例子，老是跑不了，除了上面代码片段，还有https://developers.weixin.qq.com/s/1ABYYTms881V。有人说：代码片段 不会真正打包 workers 目录，导致 workers/wk.js 根本没被编译进包，所以 主线程发出的消息永远收不到。但是我弄了一个项目，跑了也报同样错误。不知什么原因？麻烦大家给个解决方案，别沉默哦。

尊敬的微信团队，求教一个问题，新手，实在搞不懂。 cameraContext.onCameraFrame((frame) => { let uint8Array=new Uint8ClampedArray(frame.data); for(var h=0;h<height;h++)      {       for(var w=0;w<width;w++)       {         var pixelIndex=((h*width)+w)*4;//rgba;         var pixelRed=uint8Array[pixelIndex];         var pixelGreen=uint8Array[pixelIndex+1];         var pixelBlue=uint8Array[pixelIndex+2];       }     } } 问题： 上代码获取pixelRed和pixelGreen和pixelBlue都为零？想获取pixelBlue的值0~255，如何实现，谢谢了。 麻烦回复，恳教大家帮帮忙，就是要从frame.data获取每个像素点的r g b值。麻烦了。

支付成功后，回调时，回复了下面信息： <xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml> 还是执行十次以上回调，如何处理，谢谢！

尊敬的微信团队： <canvas type="2d" id="canvas'"/> const query = wx.createSelectorQuery() query.select('#canvas').fields({ node: true, size: true }) .exec((res) => {} 执行这一句老是提示：TypeError: Cannot read property 'createView' of undefined错误，如果去除type="2d"就不会错误，但是获取不到node，node==null; }); 求人，谢谢。

问下大家，我的var uploadTask=wx.uploadFile({...})老是出现了onUploadTaskStateChange 1、2、3、4... not found问题，请问如何解决？ 还有，wx.uploadFile在执行中如何中断它？ 谢谢！

下面代码，无论that放哪里，怎么整都提示：fcanvasToTempFilePath: fail canvas is empty，真是无语，麻烦求解，谢谢。 onReady: function ()   {     var that = this;     var context = wx.createCanvasContext('mycanvas',that);     wx.chooseImage     ({       success: function (res)       {         context.drawImage(res.tempFilePaths[0], 0, 0, 150, 100);         context.fillStyle = "#FF0000";         context.fillRect(0, 0, 50, 50);         context.draw(true, setTimeout(function()         {           wx.canvasToTempFilePath           ({             destWidth: 150,             destHeight: 100,             canvasId: 'mycanvas',             success: function (res)             {               console.log('1212' + res.tempFilePath);             },             fail: function (res) {console.log(res);}           },that);         },300));       }     });   }

问userInfo: {}什么意思?userInfo: {}和userInfo: null区别?
