I use QUrl to URL encode the data, it was not obvious how to do that
from the examples. You could iterate over the vector and add each value
with addQueryItem. Here's an example snipet:

QNetworkAccessManager *manager = new QNetworkAccessManager;
connect(manager, SIGNAL(finished(QNetworkReply*)),
        this, SLOT(replyFinished(QNetworkReply*)));
// Define replyFinished slot to handle the reply.

...

QNetworkRequest request;
QUrl tmpUrl;
request.setUrl(QUrl("http://localhost/test.php"));
request.setHeader(QNetworkRequest::ContentTypeHeader,
                  "application/x-www-form-urlencoded");

tmpUrl.addQueryItem("field1", "value1");
tmpUrl.addQueryItem("field2", "value2");
...

QNetworkReply *reply = manager->post(request, tmpUrl.encodedQuery());
