Sent the data instead of relying on the "submit" button of the html



  • snippet of the website
    <html>

    <form action="index.php" method="post" enctype="multipart/form-data" >
    <td><input type="file" name="upfile" size="35" /></td>
    <td><input type="submit" value="send" /></td>
    </form>

    </html>

    I want to select and send some files onto a server without manually click on
    the "file" and "send" button.Is this possible?

    Thanks





  • Thanks, looks like this is what I need.



  • Do some test and stuck, don't understand how to use it properly

    "The website I want to post":http://2cat.or.tl/~tedc21thc/live/index.php?res=549796

    The html I think it is related to my objective

    <td><input type="text" name="sub" size="35">
    <input type="submit" value="送信する" /></td>

    <td><textarea name="com" cols="48" rows="4" wrap=soft></textarea></td>

    @
    class postToKomica : public QObject
    {
    Q_OBJECT

    public:
    void sendTextToKomica()
    {
    QHttpMultiPart *multiPart = new QHttpMultiPart(QHttpMultiPart::FormDataType);

        //set the text?
        QHttpPart textPart;
        textPart.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/plain"));
        textPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"com\""));
        textPart.setBody("this is a good animation");
    
        //"click" the submit button?
        QHttpPart sendPart;
        sendPart.setHeader(QNetworkRequest::ContentDispositionHeader, QVariant("form-data; name=\"submit\""));
    
        multiPart->append(textPart);
        multiPart->append(sendPart);
    
        QUrl url("http://2cat.or.tl/~tedc21thc/live/index.php?res=549796");
        QNetworkRequest request(url);
    
        QNetworkAccessManager *manager = new QNetworkAccessManager(this);
        QNetworkReply *reply = manager->post(request, multiPart);
        multiPart->setParent(reply); // delete the multiPart with the reply
    
        connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(finished(QNetworkReply*)));
    }
    

    private slots:
    void finished(QNetworkReply *reply)
    {
    qDebug() << reply->error();
    }

    };
    @

    The reply is "0".
    I only know some basic about html,javascript and network
    What do I need to know before I can "post" the data onto
    the website with the help of QHttpMultiPart and QHttpPart?

    Thanks
