wx.openDocument偶尔打不开文件 - WXOPEN Club

当前 Bug 的表现（可附上截图）

wx.openDocument，成功调用的情况下，偶尔会打开不了文件，再次点击才能打开，开发者工具预览模式下没发现，真机调试有概率触发

提供一个最简复现 Demo

wxml:

<view class="container">

<view class="uploader" bindtap="downloadPdf" style="height:100rpx; line-height: 100rpx;">

<text>查看pdf</text>

</view>

js:

downloadPdf: function (url, id) { // 查看pdf

wx.downloadFile({

url: 'https://yjd.yxsjob.com/media/2019/1/16/f902367378ea4bfa97d995f08e1049c1/kgSbzLlWbNIxUPFphBNR.pdf',

success: function (res) {

const filePath = res.tempFilePath

wx.openDocument({

filePath: filePath,

success: function (res) {

// console.log('打开文档成功')

}

})

}

})

},
