qt QFtp 上传文件不成功

诸位老师，遇到一个问题，困惑不已。折磨2天了。

我做的工作。通过QFtp把本地文件上传到ftp服务器(file zilla)。

代码片段如下：





#include "mainwindow.h"

#include "ui_mainwindow.h"

#include <QDebug>

#include <QObject>

#include <QFile>

#include <QFtp>

#include <QIODevice>

#include <QByteArray>

#include <QMessageBox>

#include <QUrl>

#include <QNetworkRequest>

#include <QNetworkAccessManager>

#include <QFileInfo>

MainWindow::MainWindow(QWidget *parent) :

    QMainWindow(parent),

    ui(new Ui::MainWindow) {



    ui->setupUi(this);

    sourceLines.append(ui->lineEdit_s0);

    sourceLines.append(ui->lineEdit_s1);

    sourceLines.append(ui->lineEdit_s2);

    sourceLines.append(ui->lineEdit_s3);

    sourceLines.append(ui->lineEdit_s4);



    destinationLines.append(ui->lineEdit_d0);

    destinationLines.append(ui->lineEdit_d1);

    destinationLines.append(ui->lineEdit_d2);

    destinationLines.append(ui->lineEdit_d3);

    destinationLines.append(ui->lineEdit_d4);



    ui->progressBar->setRange(0,100);

    ui->progressBar->setValue(0);



    ftp = new QFtp(this) ;

    connect(ui->pushButton_0,SIGNAL(clicked()),this,SLOT(upload2Ftp()));

}



MainWindow::~MainWindow() {

    delete ui;

}



void MainWindow::inputFinish() {



}



void MainWindow::upload2Ftp() {

   int a = ftp->connectToHost("127.0.0.1");

   int islogin = ftp->login("admin","airchina"); 

  

   if(!islogin){

        QMessageBox msgBox;

        msgBox.setText("connect server failure");

        msgBox.exec();

        return ;

   }



     QFile* file = new QFile("d:/aa.txt") ;

    if(!file->open(QIODevice::ReadOnly)){

        QMessageBox msgBox;

        msgBox.setText("File Not Found");

        msgBox.exec();

    }



    QByteArray byteArray = file->readAll();

    ftp->setTransferMode(QFtp::Passive);

   

    ftp->cd("/");



    QFileInfo info("d:/aa.txt");

    ftp->put(file, info.fileName());

    connect(ftp,SIGNAL(dataTransferProgress(qint64,qint64)),this,SLOT(updateDataTranferProgress(qint64,qint64)));

    ftp->close();

   

}



void MainWindow::updateDataTranferProgress(qint64 readBytes, qint64 totalBytes)

{

    qDebug()<<"updateDataTranferProgress";

   

    ui->progressBar->setValue((readBytes/totalBytes)*100);

}
