QRCoder Html Base64 冗长的 URI 需要缩短-解网

问：

我正在尝试将冗长的 HTML URI 链接到通过 QRCoder 生成的 QR 码，但它给出了以下错误：

QRCoder.Exceptions.DataTooLongException：给定的有效负载超出了 QR 码标准的最大大小。所选参数允许的最大大小（ECC level=L，EncodingMode=Byte）为 2953 字节。

任何人都可以给我替代解决方案或一些可以在这里提供帮助的修复程序，我正在寻找一种方法来创建具有冗长 URI 的 QR 码或缩短 URI。以下是使用的代码：

QRCodeGenerator qRCodeGenerator = new QRCodeGenerator();
var htmlUri = ConvertToDataUri(qrCodeText.outputHtml, "text/html");
QRCodeData qRCodeData = qRCodeGenerator.CreateQrCode(htmlUri, QRCodeGenerator.ECCLevel.L);
QRCode qRCode = new QRCode(qRCodeData);
Bitmap bitmap = qRCode.GetGraphic(10);
byte[] BitMapArray = bitmap.BitmapToByteArray();
string QrUri = string.Format("data:image/png;base64,{0}", Convert.ToBase64String(BitMapArray));
return Ok(QrUri);

编辑：

Please use the below URI of the QR code generated from above code where I hard coded a small url instead of URI to explain:
