canvasToTempFilePath 安卓无法执行 iOS正常 - WXOPEN Club

家中两部安卓

一部魅蓝note5

一部小米MIX2

版本都是微信版本 6.6.7

2.2.1 在canvasPutImageData的 success回调中执行draw 后无法再次执行canvasToTempFilePath

但是IOS上的基础库版本2.1.3 微信版本6.6.7 相同的代码却正常执行

let windowSize = this.windowSize

let bookmark = this.bookmark

let mainCtx = this.mainCtx

let $store = this.$store

let that = this

wx.canvasGetImageData({

canvasId: 'canvas',

x: 0,

y: ((windowSize.windowHeight * 0.9) - bookmark.backgroundImage.style.height) / 2,

width: windowSize.windowWidth,

height: bookmark.backgroundImage.style.height,

success (res) {

let d = res.data

let filterData = filters[type](d, {

height: bookmark.backgroundImage.style.height,

width: bookmark.backgroundImage.style.width

})

wx.canvasPutImageData({

canvasId: 'canvas',

data: filterData,

x: 0,

y: ((windowSize.windowHeight * 0.9) - bookmark.backgroundImage.style.height) / 2,

width: windowSize.windowWidth,

height: bookmark.backgroundImage.style.height,

success: (res) => {

// 安卓上执行到这一步没反应打印mainCtx也有对象 iOS正常

mainCtx.draw(true, () => {

console.log(wx)

wx.canvasToTempFilePath({

canvasId: 'canvas',

height: windowSize.windowHeight * 0.9,

y: 0,

success: (e) => {

console.log(e)

$store.dispatch('SET_BACKGROUND_IMAGE', e.tempFilePath)

},

fail: (e) => {

},

complete: (e) => {

console.log('complete')

}

}, that)

})

}

})

}

})

我提交到体验版了不知管理员能不能直接打开体验版查一下问题
