Django获取静态文件URL [英] Django get the static files URL in view

问题描述

我正在使用reportlab pdfgen来创建PDF。在PDF中有一个由 drawImage 创建的图像。为此，我需要图像的URL或视图中图像的路径。我设法构建URL，但是如何获取图像的本地路径？

I'm using reportlab pdfgen to create a PDF. In the PDF there is an image created by drawImage. For this I either need the URL to an image or the path to an image in the view. I managed to build the URL but how would I get the local path to the image?

我如何获取URL：

prefix = 'https://' if request.is_secure() else 'http://'
image_url = prefix + request.get_host() + STATIC_URL + "images/logo_80.png"

推荐答案

谷歌的最高成绩，我以为我会添加另一种方式来做到这一点。我个人喜欢这个，因为它将实现到Django框架。

Since this is the top result on Google, I thought I'd add another way to do this. Personally I prefer this one, since it leaves the implementation to the Django framework.

# Original answer said:
# from django.templatetags.static import static
# Improved answer (thanks @Kenial, see below)
from django.contrib.staticfiles.templatetags.staticfiles import static

url = static('x.jpg')
# url now contains '/static/x.jpg', assuming a static path of '/static/'
