QHttpResponseHeader encode & Save COOKIE value %20

[wysota]

I'd prefer something like that (not tested):

QString stringToDecode;
QRegExp rx("%(\\d\\d)");
int pos = 0;
while((pos=rx.indexIn(stringToDecode, pos))!=-1){
  uint val = rx.cap(1).toUInt(0, 16);
  stringToDecode.replace(pos, 3, QString(QChar(val)));
}

QString stringToDecode;
QRegExp rx("%(\\d\\d)");
int pos = 0;
while((pos=rx.indexIn(stringToDecode, pos))!=-1){
  uint val = rx.cap(1).toUInt(0, 16);
  stringToDecode.replace(pos, 3, QString(QChar(val)));
}

To copy to clipboard, switch view to plain text mode 

After this "stringToDecode" should contain the converted string.

I recommend this code - it eliminates errors caused by previous code (hex A-F are not decimal = unrecognized by previous code, "hi%25there" represents "hi%there" = causes unwanted character creation "%th" - last replaced character has to be jumped over)

QString stringToDecode;
QRegExp rx("%(\\S\\S)");
int pos = 0;
while ((pos = rx.indexIn(stringToDecode, pos)) != -1) {
	stringToDecode.replace(pos, 3, QString(QChar(rx.cap(1).toUInt(0, 16))));
	pos++; // jumps over currently replaced character
}

QString stringToDecode;
QRegExp rx("%(\\S\\S)");
int pos = 0;
while ((pos = rx.indexIn(stringToDecode, pos)) != -1) {
	stringToDecode.replace(pos, 3, QString(QChar(rx.cap(1).toUInt(0, 16))));
	pos++; // jumps over currently replaced character
}
