PyFPDF，HTMLMixin，Python 无法打印 HTML

Question

我无法使用 PyFPDF. When I attempt to write the HTML to the PDF document 输出 HTML 消息我收到错误消息：

Traceback (most recent call last):
  File "/Users/elcid/Projects/so_test/test.py", line 8, in <module>
    pdf.write_html("<b>Sample HTML</b>")
  File "/Users/elcid/.pyenv/versions/so/lib/python3.9/site-packages/fpdf/html.py", line 400, in write_html
    text = h2p.unescape(text) # To deal with HTML entities
AttributeError: 'HTML2FPDF' object has no attribute 'unescape'

违规代码：

from fpdf import FPDF, HTMLMixin

class PDF(FPDF, HTMLMixin):
    pass

pdf = PDF()
pdf.add_page()
pdf.write_html("<b>Sample HTML</b>")
pdf.output("html.pdf")

我正在使用 Python 3.9。有什么见解吗？谢谢！

这似乎是 PyFPDF 中的错误。在内部，write_html 方法试图通过调用 Python 的 HTMLParser 的子 class 的 unescape 方法来逃避 HTML class，而不是简单地调用 html.unescape。

PyFPDF 六年没更新了 no longer actively maintained. I'd recommend trying its modern fork and successor, fpdf2.

example from the documentation 看起来运行很好：

from fpdf import FPDF, HTMLMixin

class PDF(FPDF, HTMLMixin):
    pass

pdf = PDF()
pdf.add_page()
pdf.write_html("""
  <h1>Big title</h1>
  <section>
    <h2>Section title</h2>
    <p><b>Hello</b> world. <u>I am</u> <i>tired</i>.</p>
    <p><a href="https://github.com/PyFPDF/fpdf2">PyFPDF/fpdf2 GitHub repo</a></p>
    <p align="right">right aligned text</p>
    <p>i am a paragraph <br />in two parts.</p>

    <font face="times"><p>hello times</p></font>
  </section>
  <section>
    <h2>Other section title</h2>

    <blockquote>hello blockquote</blockquote>
    <table width="50%">
      <thead>
        <tr>
          <th width="30%">ID</th>
          <th width="70%">Name</th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <td>1</td>
          <td>Alice</td>
        </tr>
        <tr>
          <td>2</td>
          <td>Bob</td>
        </tr>
      </tbody>
    </table>
  </section>
""")
pdf.output("html.pdf")

确保卸载 PyFPDF，因为它们使用相同的模块名称。
