如何从两个不同的fs方法创建对象

How to create object from two different fs methods?

本文关键字：fs 创建对象 方法 两个      更新时间：2023-09-26

我想创建对象与文件名和fileStat所以在下面的代码中，我正在检查stats与异步和文件名我使用readDir现在一旦我有值我怎么能创建对象数组?我试图获得文件名及其创建的日期，并将其发送给客户端objToReturn。你知道我怎样才能完成这个任务吗?

app.js 

function readDirectory(callback) {
    var dirPath = './logs/ditLogs';
    //this will get you list of all files. in directory
    var files = fs.readdirSync(dirPath);
    var objToReturn = [{
        fileName: '',
        fileStat: ''
    }];
    //then using async do like this
    async.eachSeries(files, function(file, callback) {
        var filePath = path.join(dirPath, file);
        fs.stat(filePath, function(err, stats) {
            objToReturn.fileStat = stats;
            //write stats data into objToReturn
            fs.readdir(path, function(err, items) {
                objToReturn.filename = items;
            });
            callback();
        });
    }, function(err) {
        //final callback when all files completed here send objToReturn to client
        callback(objToReturn);
    });

好了，我想我明白你的意思了。您希望读取给定目录中的所有文件路径，然后为每个文件收集信息，然后将这些信息返回给给定的回调。现在看来，您正在将这些道具添加到数组objToReturn中，而不是将每个对象推入objToReturn。通过这种方式，您可以覆盖每次异步读取的属性。

你也用fs.readdir(path, function(err, items) {，我认为你指的是你之前声明的filePath。

试试这样写:

async.eachSeries(files, function(file, callback) {
    var filePath = path.join(dirPath, file);
    var fileInfo = {};
    fs.stat(filePath, function(err, stats) {
        fileInfo.fileStat = stats;
        //write stats data into objToReturn
        fs.readdir(filePath, function(err, items) {
            fileInfo.filename = items;
        });
        objToReturn.push(fileInfo);
        callback();
    });
}, function(err) {

你可以试试:

function readDirectory(callback) {
    var dirPath = './logs/ditLogs';
    //this will get you list of all files. in directory
    var files = fs.readdirSync(dirPath);
    var objToReturn = [];
    //then using async do like this
    async.eachSeries(files, function(file, callback) {
        var filePath = path.join(dirPath, file);
        fs.stat(filePath, function(err, stats) {
            objToReturn.fileStat = stats;
            //write stats data into objToReturn
            fs.readdir(path, function(err, items) {
                objToReturn.filename = items;
                objToReturn.push({
                    fileName: items,
                    fileStat: stats
                })
            });
            callback();
        });
    }, function(err) {
        //final callback when all files completed here send objToReturn to client
        callback(objToReturn);
    });
}
