Nodejs实现多文件夹文件同步
本文实例为大家分享了Nodejs实现多文件夹文件同步的具体代码,供大家参考,具体内容如下
package.json
{
"name": "asyncFile",
"version": "0.0.1",
"dependencies":{
"fs-sync":"",
"later":""
}
}
asycnFile.js
var fsSync = require('fs-sync');
var fs = require('fs');
var util = require("util");
var later = require("later");
//需要同步的文件夹路径
var path = {
"pathOne": "/home/lincoln/testAsync/dirOne/",
"pathTwo": "/home/lincoln/testAsync/dirTwo/"
};
//需要同步的文件夹名称
var asyncDir = ["img", "music"];
var dirFilesOne;
var dirFilesTwo;
//读取文件夹信息
function readDir(dirName){
dirFilesOne = fs.readdirSync(path.pathOne + dirName);
dirFilesTwo = fs.readdirSync(path.pathTwo + dirName);
}
//使用fs-sync模块拷贝文件信息
function useFileCopy(sourcePath,distPath,copyFiles) {
for(var index in copyFiles){
fsSync.copy(sourcePath+copyFiles[index],distPath+copyFiles[index])
}
}
//统计需要同步的文件信息
function needCopyFiles(sourceFiles, distFiles) {
var needCopyFiles = [];
for (var index in sourceFiles) {
if (distFiles.indexOf(sourceFiles[index]) == -1) {
needCopyFiles.push(sourceFiles[index]);
console.log("needAsyncFile-->"+sourceFiles[index]);
}
}
return needCopyFiles;
}
//同步文件
function copyFile(dirName) {
var sourcePath = path.pathOne + dirName +"/";
var distPath = path.pathTwo + dirName +"/";
readDir(dirName)
useFileCopy(sourcePath,distPath,needCopyFiles(dirFilesOne,dirFilesTwo));
readDir(dirName);
useFileCopy(distPath,sourcePath,needCopyFiles(dirFilesTwo,dirFilesOne));
}
//for (var index in asyncDir) {
// //console.log(asyncDir[index])
// console.log(new Date() +" 执行同步--->"+asyncDir[index])
// copyFile(asyncDir[index]);
//}
var sched = later.parse.recur().every(10).second(),
t = later.setInterval(function() {
for (var index in asyncDir) {
//console.log(asyncDir[index])
console.log(new Date() +" 执行同步--->"+asyncDir[index]);
copyFile(asyncDir[index]);
}
}, sched);
代码只是能用,菜鸟写法,等js这块有深入理解了之后,再修改这块的代码,也希望js大牛指点。
