我有一个Node Webkit桌面应用程序,需要从服务器下载文件并在用户离线时本地保存.当我知道文件名是什么时,我可以下载并保存文件,但是如何读取服务器上目录的内容以便下载每个文件?
function cacheFiles(filelink, filepath, cb) {
var path_array = filelink.split("/");
var foldername = path_array[path_array.length - 2]
//create new folder for locally html files
var newdir = filepath + '/' + foldername;
if (fs.existsSync(newdir)){
alert('file already exists, cannot cache this file.');
} else {
fs.mkdirSync(newdir);
}
//download and save index.html - THIS WORKS
var indexfile = fs.createWriteStream(newdir+'/index.html');
var request = http.get(filelink, function(response) {
response.pipe(indexfile);
indexfile.on('finish', function() {
indexfile.close(cb);
});
});
//read contents of data folder - THIS DOESN'T WORK
var datafolder = filelink.replace('index.html','');
fs.readdir( datafolder, function (err, datafiles) {
if (!err) {
console.log(datafiles);
}else{
console.log(err) ;
}
});

我在控制台中遇到的错误是:
"ENOENT:没有这样的文件或目录,scandir'C:\ Users\my.name\desktopApp\app\http:\ www.mysite.co.uk\wp-content\uploads\wifi_corp2\data'"
以上是在本地查找文件而不是我在filelink中提供的在线链接, 例如. http://www.mysite.co.uk/wp-content/uploads/wifi_corp2/data
