wx.openDocument打不开jpg文件
wx.downloadFile({url:"https://imgsrc.baidu.com/baike/pic/item/b21bb051f81986187aa0646a48ed2e738ad4e67d.jpg", success: function(res){ // success console.log('down success') console.log(res.tempFilePath) var filePath = res.tempFilePath wx.openDocument({ filePath: filePath, success: function(res){ // success console.log('open success') }, fail: function() { // fail console.log('open fail') }, complete: function() { // complete } }) }, fail: function() { // fail console.log('down fail') }, complete: function() { // complete } }) |
如上面代码，怎么总是返回“open fail”
