It looks like Qhttp::request(const QHttpRequestHeader &header, QIODevice* data, QIODevice *to)
method does not send request parameters for GET request.

Method Qhttp::request(header,data ...) sends a request type defined in header.
And this can be POST,GET etc.

Qhttp::request(header,data ...) should send request parameters as data variable. It is OK for POST.
But it does not send it for GET

I do not want to use Qhttp::get() method because I need to send a special defined request header to server.

Use QTcpSocket instead.

qt 4:

Very simplified example without signals & slots for stateChanges implemented.

Source code

// Requestheader goes in here
QByteArray *buf = new QByteArray("GET / HTTP/1.1\r\nHost: host.com\r\nConnection: close\r\n\r\n");

// Connection to host
QTcpSocket *sock = new QTcpSocket();
sock->connectToHost("host.com",80,QIODevice::ReadWrite);
sock->write(buf->data(),buf->length());

// implement check for data available to be recieved.
x
x
x

// clear the buffer and read all available data from socket.
buf->clear();
buf->append(sock->readAll());
sock->disconnectFromHost();

// response goes into buf.

Thank you moogle,
I will consider this possibility

But I think it should be a way to send GET parameters through Qhttp::request()

Okay, so the only thing you want to do is send a GET-parameter?

Why can´t you do it with QHttp?

Source code

QHttp *http = new QHttp();
QFile file("recv.txt");
if (file.open(QIODevice::WriteOnly)) {
    http->setHost("www.host.com",80);
    http->get("/path/to/url.php?id=100&s=10",&file);
    file.close();
    http->closeConnection();
}

Sends $_GET["id"] (= 100) and $_GET["s"] (= 10) to a phpscript.

moogle,

Quoted

Not the only,
I need to send GET parameters with customized HTTP header.
That's why I need to use Qhttp::request(header,...)

Qhttp::get() sends it's own header, that can not be customised.

The problem is that Qhttp::request() does not send GET request parameters, as it is axpected. It has a bug

Well, it looks like QTcpSocket is the only choise.

I have found the solution!

When the custom request header is being constructed for GET request,
then all request parameters must be added there (to strPath).
As a string like "?aaa=123&ccc=456"

QString strPath = strRealURLPath;
if (GET == strRequestType) strPath += "?aaa=123&ccc=456";
QHttpRequestHeader* pHeader = new QHttpRequestHeader(strRequestType, strPath);

It should not be done for POST request.

Then we can send both POST and GET requests with custom header and request parameters through Qhttp::request() method.
