在pdf weasyprint中附加img文件

2022-03-04 00:00:00 python django weasyprint pdf-generation

问题描述

我需要帮助在pdfs中附加img文件。我们使用WeasyPrint库从html生成pdf。

在html中像这样连接img文件

<img src="1.png" alt="">
<img src="2.png" alt="">
<img src="3.png" alt="">

但它不起作用。我没有看到图像。

解决方案

图片文件路径使用静电

  {% load static %}
    <img src="{% static 'images/static.jpg' %}" alt="">

并在views.py的HTML类中传递base_url

pdf_file = HTML(string=rendered_html, base_url=request.build_absolute_uri())

HTML文件

<!DOCTYPE html>
<html lang="en">
{% load static %}
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
    <div>
        <img src="{% static 'images/static.jpg' %}" alt="">
    </div>
</body>
</html>

views.py

from django.template.loader import get_template
from weasyprint import HTML, CSS
from django.conf import settings
from django.http import HttpResponse


def generate_pdf(request):
    html_template = get_template('latest/html_pdf.html')
    user = request.user
    rendered_html = html_template.render().encode(encoding="UTF-8")
    pdf_file = HTML(string=rendered_html, base_url=request.build_absolute_uri()).write_pdf(stylesheets=[CSS(settings.STATIC_ROOT +  '/css/generate_html.css')])



    http_response = HttpResponse(pdf_file, content_type='application/pdf')
    http_response['Content-Disposition'] = 'filename="generate_html.pdf"'

    return http_response
