uniapp modify local file name

background

After uniapp downloads the local saveFile, the file name is in the form of a timestamp. And the uniapp official website does not have a method for file modification

After struggling for a day, it was finally resolved.

directly on the code

code part

Use plus.io's file management method. (I have to complain, this document is really written in the clouds and rain and fog)

	/**
	 * 修改文件名。
	 * @param {旧的文件路径} oldFilePath 
	 * @param {新的文件名} newFileName 
	 */
	function RenameFile(oldFilePath,newFileName) {
    
    
		plus.io.resolveLocalFileSystemURL(oldFilePath, entry => {
    
    
			entry.getParent(_oldFile=>{
    
    
				entry.moveTo(_oldFile,'/'+newFileName,newFilePath=>{
    
    
					console.log('newFilePath',newFilePath.fullPath)
				})
			}) 
		})
	}

Tips: The name of this method should be changed with a suffix, or it can be changed to a Promise method

Used in conjunction with uni.getSavedFileList, you can directly call the file path returned by uni.getSavedFileList.
