生成二维码的方法
Generates a QR code based on the provided content and type.
内容：要编码为二维码的字符串数据 | Content: The string data to encode into the QR code.
类型：指定生成的二维码格式（SVG 或 PNG） | Type: Specifies the format of the QR code (SVG or PNG).
返回值：成功时返回 QrCodeOutput，失败时返回错误 | Returns: QrCodeOutput on success, error on failure.
使用 QRBuilder 创建二维码对象 | Create a QR code object using QRBuilder.
