I try to use the npm qrcode API with express. When the user enters an address into a form, the QR-Code should be displayed on the website. I searched for a long time, but can't figure it out, since I don't understand what to loog for exactly.
I tried the following:
app.post('/ausgabe', async (req, res) => {
try {
res.setHeader('200', { 'Content-type': 'application/json' });
const eingabe = `'${req.body.address}'`;
const qrImage = await generateQR(eingabe);
console.log(qrImage);
const body = `<!DOCTYPE html>
<html lang="de">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>QR-Code</title>
</head>
<body>
<img ${qrImage} />
</body>
</html>`;
res.send(body);
} catch (err) {
res.status(404).json({
status: 'Fail',
message: err,
});
}
});
I console.logged 'qrImage' and it's there and correct, but there is nothing showing up in the HTML.
Thanks a lot, TobiG
