我正在做一个项目，我想在网站上显示许多图像，这样用户就可以下载它们。我可以显示图像的名称，但下载不起作用。我认为这是我的观点，因为我正在使用Django，并得到错误the current path ... didn't match any of this。包含图像的目录的名称为Images，其中还有其他子目录，在这些子目录中，有图像。
我的浏览页面，我认为问题就在这里，在下载功能：
from django.shortcuts import render
import os
from django.http import HttpResponse, Http404
from django.http import FileResponse
def index(request):
flPath = os.listdir('Images/')
fl4 = []
for root, dirs, files in os.walk("Images/", topdown=False):
for name in files:
fl4.append(os.path.join(root, name))
for name in dirs:
fl4.append(os.path.join(root, name))
return render(request, 'catalog/index.html', {'path': fl4})
def downloadImage(request, path):
imagePath = 'Images/'
file_path = os.path.join(imagePath, path)
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type='text/csv')
response['Content-Disposition'] = 'inline; filename=' + file_path
return response
raise Http404
我的应用程序网址，目录网址：
from django.urls import path, include
from .views import *
urlpatterns = [
path('', index, name='index'),
path('Images/<str:path>', downloadImage, name='download'),
]
我的项目URL，SiteSmu4Img:
from django.contrib import admin
from django.urls import path, include
from django.views.generic import RedirectView
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = [
path('admin/', admin.site.urls),
path('Images/', include('catalog.urls')),
path('', include('catalog.urls')),
]
我的index.html:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/html">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% if path %}
<table>
<tr>
<th>Images</th>
<th>Download</th>
</tr>
{% for i in path %}
<tr>
<td>{{ i }}</td>
<td><a href="{{ i }}">download</a></td>
</tr>
<img src="Images/{{ i }}">
{% endfor %}
</table>
{% endif %}
</body>
</html>

代码中的问题是：
catalog.urls:path('Images/', include('catalog.urls')),
站点Smu4IMg:path('Images/<str:path>', downloadImage, name='download'),
所以总的来说路径应该像CCD_，但在模板中，您只有：<img src="Images/{{ i }}">
首先更正此问题，如果解决方案无法修复所有错误，则显示堆栈竞争。
在模板中添加另一个Images作为开头，并在路径中添加前导斜杠：
<img src="/Images/Images/{{ i }}">
您无法直接获取图像或任何静态文件。
Django查找静态文件夹或媒体文件夹的资源。
在静态文件夹中添加图像，并在设置中添加STATIC_FOLDER、STATIC_URL值.py
如果要通过网站添加图像，请在settings.py中设置MEDIA_ROOT、MEDIA_URL
在urls.py中添加URL。现在您可以通过Django访问图像了。
获取媒体文件访问
