nodejs重命名文件

const fs = require(‘fs’);
const path = require(‘path’);
//需要命名的文件所在路徑
let filePath = ‘./man/’;
let index = 1;
//遍歷文件
recursiveReadFile = function (fileName) {
if (!fs.existsSync(fileName)) return;
if (isFile(fileName)) {
// reName (fileName, index);
// index += 2;
return;
}

if (isDirectory(fileName)){
    let files = fs.readdirSync(fileName);
    files.forEach(function (value, key) {
        let temp = path.join(fileName, value);
        if (isDirectory(temp)) recursiveReadFile(temp);
        if (isFile(temp)) {
            reName (temp, index);
            index += 2;
        }
    })
}

};
//重命名
reName = function (fileName, newName) {
let data = readFile(fileName);
console.log("fileName = "+fileName);
//fs.rename(oldPath, newPath, callback)
fs.rename(fileName,filePath+newName+’.jpg’, function(err){
if(err){
throw err;
}
console.log(‘done!’);
})
};
//判斷是否是文件目錄
isDirectory = function (fileName) {
if (fs.existsSync(fileName))
return fs.statSync(fileName).isDirectory();
};
//判斷是否是文件
isFile = function (fileName) {
if (fs.existsSync(fileName))
return fs.statSync(fileName).isFile();
};
//讀取文件
readFile = function (fileName) {
if (fs.existsSync(fileName))
return fs.readFileSync(fileName, ‘utf-8’);
};
recursiveReadFile(filePath);
