I found a way to get base64 data. The code is as follows:

var element = document.getElementById('zPrintDiv');
        var worker = html2pdf(element).toPdf();;
        worker = worker.output("datauristring").then(function (pdf) {
            console.log("conve pdf ok：")
            console.log(pdf);//this is base64 Data
        });

            console.log(pdf);//this is base64 Data
        });

Using the above method generates a double of the first page when I convert the base64 into pdf using the following code in Firefox:

$base_to_php = explode(',', $baseFromJavascript);

$data = base64_decode($base_to_php[1]);

header('Content-Type: application/pdf');

echo $data;

Is there any way around this?
