我已經創建了一個基於節點的SSH2 SFTP服務器和客戶端。我的目標是讀取SFTP服務器的目錄結構。假設我有一個包含temp文件夾的SFTP服務器，我想讀取temp目錄內的文件。我使用ssh2 npm模塊來創建SFTP服務器和客戶端。它正在連接SFTP服務器，但沒有列出該目錄使用節點js讀取目錄的SFTP服務器
下面是代碼
客戶端SFTP
var Client = require('ssh2').Client;
var connSettings = {
host: 'localhost',
port: 22,
username:'ankit',
password:'shruti',
method:'password'
// You can use a key file too, read the ssh2 documentation
};
var conn = new Client();
conn.on('ready', function() {
console.log("connected to sftp server")
conn.sftp(function(err, sftp) {
if (err)
throw err;
sftp.readdir('',function(err,list)
{
console.log('Inside read')
if(err)
{
console.log(err);
throw err;
}
console.log('showing directory listing')
console.log(list);
conn.end();
})
/**
var moveFrom = "/remote/file/path/file.txt";
var moveTo = __dirname+'file1.txt';
sftp.fastGet(moveFrom, moveTo , {}, function(downloadError){
if(downloadError) throw downloadError;
console.log("Succesfully uploaded");
