Encoding charcters like "+" with QUrlQuery

I am trying to encode POST Http queries using QUrlQuery. Reading at several places, this seems to be the solution:

QUrlQuery query;
query.addQueryItem("name","value");
QString queryString = query.query(QUrl::FullyEncoded);

but this code:

QUrlQuery query;
query.addQueryItem("calc","x+x");
qDebug() << query.query(QUrl::FullyEncoded);

Outputs:

"calc=x+x"

So the "+" did not get encoded. Why? And how do I properly encode an arbitrary String for POST parameters?

Solution

  • QUrlQuery is only part of QUrl.

    If by encoding you mean percent encoding, then you can do it with code like this:

    qDebug() << QUrl::toPercentEncoding(query.toString());
