使用 flask 将 html 表转换为 pdf

Question

I'm tried to solve the following problem using pdfkit.我尝试使用 pdfkit 解决以下问题。

when I add wkhtmltopdf configuration to my app then my app can't load into the browser even the index page cant load into the browser.当我将 wkhtmltopdf 配置添加到我的应用程序时，我的应用程序无法加载到浏览器中，即使索引页面也无法加载到浏览器中。 but when I remove wkhtmltopdf configuration from my app then my all routes work fine only the HTML to pdf route gives me the following error.但是当我从我的应用程序中删除 wkhtmltopdf 配置时，我的所有路由都可以正常工作，只有 HTML 到 pdf 路由给了我以下错误。

OSError: No wkhtmltopdf executable found: "b''"
If this file exists please check that this process can read it. Otherwise please install wkhtmltopdf - https://github.com/JazzCore/python-pdfkit/wiki/Installing-wkhtmltopdf

Configuration:配置：

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)

route.py code: route.py 代码：

@app.route('/leave_worker_pdf', methods=['POST'])
def leave_worker_pdf():
    leave_worker = LeaveWorker.query.all()
    html = render_template("leave_worker_pdf.html", leave_worker=leave_worker)
    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

HTML markup: HTML 标记：

        <tbody>
          <tr>
            <td> {{ worker.id }}</td>
            <td> {{ worker.leave_worker_name }} </td>
            <td> {{ worker.leave_worker_address }} </td>
            <td> {{ worker.leave_worker_contact }} </td>
            <td> {{ worker.leave_date.strftime('%Y-%m-%d') }} </td>
            <td> {{ worker.admin.username }} </td>
          </tr>
        </tbody>
        {% endfor %}
    </table>
  
  </div>
</body>
</html>

If you're running this flask application on a remote server, you might have difficulty setting up wkhtmltopdf.如果您在远程服务器上运行此 flask 应用程序，则可能难以设置 wkhtmltopdf。 I was unable to do so and had to resort to using python library reportlab in order to create this solution.我无法这样做，不得不求助于使用 python 库 reportlab 来创建此解决方案。

Here's a git repo w/ code from someone who wrote a book on reportlab if you're interested in pursuing that as a solution.这是一个 git 存储库，带有代码，如果您有兴趣将其作为解决方案，请写关于 reportlab 的书。
