Hi all, I’m trying to put a simple HTTP server in my Qt5 application.
I’m actually using QHttpServer because of it’s semplicity.
This is the code:
...
QHttpServer *server = new QHttpServer;
server->listen(QHostAddress::Any, 5001);
connect(server, SIGNAL(newRequest(QHttpRequest*, QHttpResponse*)),
this, SLOT(handle(QHttpRequest*, QHttpResponse*)));
...
void MyObject::handle(QHttpRequest *req, QHttpResponse *resp)
{
qDebug() << req->path();
qDebug() << req->remoteAddress();
qDebug() << req->methodString();
qDebug() << req->body().size();
QUrlQuery url_query(req->url());
qDebug() << url_query.queryItems();
QString risposta_http;
risposta_http = "<html><head><title>Greeting App</title></head><body>";
risposta_http += "<b>YOUR IP: " + req->remoteAddress() + "<br><br></b>";
risposta_http += "<form name=\"input\" action=\"\" method=\"GET\">"
"Username: <input type=\"text\" name=\"user\">"
"<input type=\"submit\" value=\"Submit\">"
"</form> ";
risposta_http += "</body></html>";
resp->setHeader("Content-Length", QString::number(risposta_http.size()));
resp->writeHead(200);
resp->write(risposta_http);
resp->end();
}
This way when I point my browser to: localhost:5001 I get a simple HTTP form where I can put my name.
The first time I connect to the web server I get the following “debug messages” in the top of “handle()”:
"/"
"127.0.0.1"
"HTTP_GET"
0
()
Then if I enter a name “Luca” and press “submit” in the browser I get this debugs:
"/"
"127.0.0.1"
"HTTP_GET"
0
(QPair("user","Luca") )
and this is what I expect.
If I user POST instead of GET:
risposta_http += "<form name=\"input\" action=\"\" method=\"POST\">"
"Username: <input type=\"text\" name=\"user\">"
"<input type=\"submit\" value=\"Submit\">"
"</form> ";
I can’t get the name I insert in the form:
(QPair("user","Luca") )
Can someone tell me why?
Thanks
