Question

我正在尝试使用报告实验室将我创建的html文档转换为pdf。 html文档如下。我不确定如何做到这一点，我已经在网上看了，似乎无法找到解决方案。

html文件

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8">

  <title>Convert to Pdf</title>
</head>

<body>
 <h2>Convert to pdf</h2>
 <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec at tempus massa. Quisque congue dui venenatis rutrum imperdiet. Nulla congue magna sit amet magna posuere, in elementum felis dapibus. Mauris maximus feugiat lorem, a bibendum orci fringilla a. Pellentesque rhoncus dignissim tempus. Aliquam semper convallis odio ut pharetra. Nunc bibendum neque at bibendum ornare. Curabitur lobortis odio ac turpis tincidunt, at venenatis nibh blandit.

Donec ac risus lacus. Pellentesque sagittis vitae odio quis vulputate. Praesent efficitur urna mollis, cursus tellus euismod, pulvinar sem. Morbi maximus orci nisi. Fusce tempor condimentum lacus nec pulvinar. Aenean tristique eu nibh vitae facilisis.

如果你使用django框架，你可以使用django-easy-pdf。我认为这是从Html生成PDF最难以理解的方式。这是我项目的模板和视图：

#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 %}

＆＃13;

您还可以通过覆盖PDFTemplateViews来使用基于类的视图。您可以在Docs上看到更多信息。

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

<强> 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')
