Converting QString to Base64

[Chaki]

Hello,
I am currently facing the problem that I am not able convert a QString to a base64 code. This is my current try:

QString filepath = "C:\example.txt";
QFile file(filepath);
file.open(QIODevice::ReadOnly | QIODevice::Text);
QString line;
QTextStream in(&file);

while(!in.atEnd()){
    line.append(in.readLine());
}
 QString base64 = line;
 base64.toUtf8().toBase64();
 qDebug()<<base64;

The Output is not a base64 code

Hi,

What input do you have ?
What output do you expect ?
What output do you get ?

@Chaki said in Converting QString to Base64:

base64.toUtf8().toBase64();

C++ basics - what do you expect from this line?

@Chaki
When you read https://doc.qt.io/qt-5/qbytearray.html#toBase64 you see:

QByteArray QByteArray::toBase64() const
`Returns a copy of the byte array, encoded as Base64.

So it is a function returning a result.

@Christian-Ehrlicher i thought this line converts a QString to a base64 code

Correct, but the result is thrown away since you don't save the return value - c basics.
