Hallo zusammen,
ich benutze fetch um diese PHP-Datei (listen_aus_db_laden.php) aufzurufen. Das hat auch bis ich heute ein Windows_update gemacht habe und den Rechner neugestartet habe, funktioniert. Jetzt erhalte ich aber folgende Fehlermldung:
app1.js:179 Fetch API cannot load file:///D:/xampp/htdocs/supertramp/localhost/supertramp/listen_aus_db_laden.php. URL scheme must be "http" or "https" for CORS request.

Ich benutze xampp und habe alle Datein die ich aufrufe in dem Ordner Supertramp:
D:\xampp\htdocs\supertramp:
Ich habe bereits versucht, , die Datei mit localhost/supertramp/listen_aus_db_laden.php   zu laden.
Hier der relevante Code.:
Vielen Dank für mögliche Vorschläge und Lösungsansätze.
function fetchData() {
        fetch('listen_aus_db_laden.php').then(function (rep) {
        return rep.json()
        }).then(function (data) {
        //console.log(data);
        
        let result = data
        result2= JSON.stringify(result);
        output1.textContent = result2;
        trips=  output1.textContent;
        trips= JSON.parse(trips);
})
      
        };
