ionic-framework - Ionic 3 Cordova 文件插件为 copyFile 操作提供错误

Question

我正在尝试使用 copyFile(path, fileName, newPath, newFileName) 函数将文件从一个目录复制到另一个目录。它会给出类似 {"code":13, "message":"input is not a directory"} 的错误。该文档只有 12 个错误代码，没有第 13 个。我想知道我做错了什么。

这是我的实际代码示例。

this.path = "file:///storage/emulated/0/TheFolder/thefile.ext";
this.newPath = "file:///storage/emulated/0/NewFolder";

this.fileCtrl.copyFile(this.path, fileName, this.newPath, newFileName)

Answer 1

this.path 必须是一个目录但是你显示的是一些文件名

如下更改代码

this.path = "file:///storage/emulated/0/TheFolder";
this.newPath = "file:///storage/emulated/0/NewFolder";

this.fileCtrl.copyFile(this.path, YOUR_EXISTING_FILE_NAME, this.newPath, NEW_FILE_NAME);


path -Base FileSystem
fileName - Name of file to copy
newPath - Base FileSystem of new location
newFileName - New name of file to copy to (leave blank to remain the same)
