下面是我的代码，想通过wx.getImageInfo获取网络图片后，然后用drawImage在canvas上将图片显示出来，但是一直报错。 代码如下： onShow: function () { var that = this const query = wx.createSelectorQuery() query.select('#shareCanvas') .fields({ node: true, size: true }) .exec((res) => { const canvas = res[0].node const ctx = canvas.getContext('2d') const dpr = wx.getSystemInfoSync().pixelRatio canvas.width = res[0].width * dpr canvas.height = res[0].height * dpr ctx.scale(dpr, dpr) wx.getImageInfo({ src: that.data.photoUrl, success(res) { console.log("头像路径："+res.path) ctx.drawImage(res.path, 0, 0) ctx.draw() } }) }) }, 报错信息如下： thirdScriptError Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(CSSImageValue or HTMLImageElement or SVGImageElement or HTMLVideoElement or HTMLCanvasElement or ImageBitmap or OffscreenCanvas)';at api getImageInfo success callback function TypeError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': The provided value is not of type '(CSSImageValue or HTMLImageElement or SVGImageElement or HTMLVideoElement or HTMLCanvasElement or ImageBitmap or OffscreenCanvas)'     at CanvasRenderingContext2D.e.drawImage (http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:647372)     at success (http://127.0.0.1:51536/appservice/pages/card/img.js:47:15)     at Function.o.<computed> (http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:1366445)     at Object.success (http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:124200)     at y (http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:526317)     at v (http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:526555)     at http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:528109     at n.<anonymous> (http://127.0.0.1:51536/appservice/__dev__/asdebug.js:1:12078)     at http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:124200     at http://127.0.0.1:51536/appservice/__dev__/WAService.js:2:107123

复现步骤【稳定复现】： 1、点击全屏按钮之前，让直播暂停播放，点击全屏按钮之后，调用全屏方法，会自动播放直播 2、当前状态为全屏，暂停播放，点击退出全屏按钮，进行退出全屏操作，变成半屏状态，也会变成播放，没有暂停 预期表现： live-player 组件不管调用退出全屏方法，还是全屏方法，都不会改变直播的播放状态。 录屏视频：http://share.plvideo.cn/front/video/preview?vid=cec4219165113bde29682a517d9276e2_c
