如果使用django框架，可以使用django easy pdf。我认为这是从Html生成PDF的最简单的方法。以下是我的项目的模板和视图：

#Import the easy_pdf rendering
from easy_pdf.rendering import render_to_pdf_response

#Here's the detail view function
def detail_to_pdf(request,id):
    template = 'renderdetail.html'
    kucing = Kucing.objects.get(id = id)
    context = {'kucing' : kucing}
    return render_to_pdf_response(request,template,context)

模板是：

&13；

{% extends "base.html" %}

{% block extra_style %}
    <style type="text/css">
        body {
            font-family: "Helvetica", "sans-serif";
            color: #333333;
        }
    </style>
{% endblock %}

{% block content %}
    <div id="content">
        <div class="main">
            <h1>PROFILE : {{ kucing.nama }}- ID:{{ kucing.id }}</h1>
            <img src="/media/{{ kucing.foto }}"><br>
            <p>Nama : {{ kucing.nama }}</p><br>
            <p>Hp : {{ kucing.hp}}</p><br>
            <p>Poin : {{ kucing.poin }}</p><br>
            <a href="{% url 'kucing_makan' kucing.id %}">Makan</a>
            <a href="{% url 'kucing_berburu' kucing.id %}">Berburu</a>
            <hr>
            <h5><a href="{% url 'kucing_home' %}">Back To Home</a></h5>|
            <h5><a href="{% url 'kucing_list' %}">See Another Kucing</a></h5>
        </div>
    </div>
{% endblock %}

；

您还可以通过重写PDFTemplateViews来使用基于类的视图。你可以在Docs上看到更多。

正如您已经知道如何使用ReportLab，我想这可以完成以下工作： https://github.com/xhtml2pdf/xhtml2pdf

xhtml2pdf

使用ReportLab将HTML转换为pdf的库

或者您可以使用pdfkit：

https://pypi.python.org/pypi/pdfkit

在使用之前，您需要安装一些东西：

pip install pdfkit
sudo apt-get install wkhtmltopdf

生成pdf的示例代码：

import pdfkit

pdfkit.from_url('http://stackoverflow.com', 'out.pdf')
pdfkit.from_file('test.html', 'out2.pdf')
pdfkit.from_string('Thanks for reading!', 'out3.pdf')
