我使用flask作为网络框架，代码如下：

    rendered = render_template("order-summary.html",total_cost=total_cost,name=name,price=price)
    config = pdfkit.configuration(wkhtmltopdf=r'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe')
    pdf = pdfkit.from_string(rendered,False,configuration=config)
    response = make_response(pdf)
    response.headers['Content-Type'] = 'application/pdf'
    response.headers['Content-disposition'] = 'inline; filename=output.pdf'
    return response

我在互联网上进行了搜索，但没有找到解决问题的相关信息。
