我正在尝试使用烧瓶将 HTML 转换为 pdf。
我可以使用以下软件包。
- pdf工具包
- wkhtmltopdf
当我运行服务器时，它无法加载到浏览器中，即使主页也无法加载到浏览器中。我不明白它有什么问题。

route.py代码：
config = pdfkit.configuration(wkhtmltopdf='C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe')
pdfkit.from_url('http://127.0.0.1:5000/leave_worker_pdf', 'output.pdf', configuration=config)
@app.route('/leave_worker_pdf')

leave_worker = LeaveWorker.query.all()
html = render_template(

pdf = pdfkit.from_string(html, False)
response = make_response(pdf)
response.headers["Content-Type"] = "application/pdf"
response.headers["Content-Disposition"] = "inline; filename=output.pdf"
return response
