是的,在Qt中有替代QFtp模块的FTP代码,您可以使用QNetworkAccessManager和QNetworkReply来实现FTP操作。尽管QNetworkAccessManager不能完全替代QFtp,但是您可以使用QNetworkAccessManager实现FTP的大部分功能。
下面是使用QNetworkAccessManager进行FTP上传和下载的示例代码:
FTP上传示例代码:
```cpp
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
QUrl url("ftp://ftp.example.com/uploadfile.txt");
url.setUserName("username");
url.setPassword("password");
QFile file("/path/to/local/file.txt");
if (file.open(QIODevice::ReadOnly)) {
QNetworkRequest request(url);
QNetworkReply* reply = manager->put(request, &file);
connect(reply, &QNetworkReply::finished, [reply]() {
if (reply->error() == QNetworkReply::NoError) {
qDebug() << "Upload success!";
} else {
qDebug() << "Upload failed:" << reply->errorString();
}
reply->deleteLater();
});
}
```
FTP下载示例代码:
```cpp
QNetworkAccessManager* manager = new QNetworkAccessManager(this);
QUrl url("ftp://ftp.example.com/downloadfile.txt");
url.setUserName("username");
url.setPassword("password");
QNetworkRequest request(url);
QNetworkReply* reply = manager->get(request);
connect(reply, &QNetworkReply::finished, [reply]() {
if (reply->error() == QNetworkReply::NoError) {
QFile file("/path/to/local/file.txt");
if (file.open(QIODevice::WriteOnly)) {
file.write(reply->readAll());
qDebug() << "Download success!";
}
} else {
qDebug() << "Download failed:" << reply->errorString();
}
reply->deleteLater();
});
```
请注意,上述示例代码假定您已经有FTP服务器的用户名和密码,并且您已经有可用的本地文件路径。您需要将这些值替换为实际值。
