当我在文件上使用readdir时，文件的大小是正确的。

使用FTP(JSFTP)对我的开发FTP服务器使用上面相同的技术工作得很好。

任何建议表示赞赏！

这是我的代码：

var Client = require('ssh2').Client;

var m_ssh2Credentials = {

host: config.ftpHostName,

port: config.ftpPort,

username: config.ftpUser,

password: config.ftpPassword,

readyTimeout: 20000,

algorithms: { cipher: ["3des-cbc", "aes256-cbc", "aes192-cbc","aes128-cbc"]}

};

...

var conn = new Client();

var dataLength = 0;

conn.on('ready', function() {

conn.sftp(function(err, sftp) {

if (err) {

writeToErrorLog("downloadFile(): Failed to open SFTP connection.");

} else {

writeToLog("downloadFile(): Opened SFTP connection.");

}

var streamErr = "";

var dataLength = 0;

var stream = sftp.createReadStream(config.ftpPath + "/" + m_fileName)

stream.on('data', function(d){

data.push(d);

dataLength += d.length;

});

.on('error', function(e){

streamErr = e;

})

.on('close', function(){

if(streamErr) {

writeToErrorLog("downloadFile(): Error retrieving the file: " + streamErr);

} else {

writeToLog("downloadFile(): No error using read stream.");

m_fileBuffer = Buffer.concat(data, dataLength);

writeToLog("Data length: " + dataLength);

writeToLog("downloadFile(): File saved to buffer.");

}

conn.end();

});

})

})

.on('error', function(err) {

writeToErrorLog("downloadFile(): Error connecting: " + err);

}).connect(m_ssh2Credentials);
