我正在尝试通过将django与html5视频标签一起使用来播放视频,但不能。 主要问题是服务器无法获取视频文件。 我收到此错误:
I am trying to play a video by using django with html5 video tag but couldn't. The main problem is that the server cannot get a video file. I got this error:
[06/Jan/2014 23:52:07] "GET absolute_path_of_media/sample.mp4 HTTP/1.1" 404 2422元素:
在这里,我将向您展示我的代码。 templates / videoplay.html:
Here, I will show you my code. templates/videoplay.html:
{% extends "app/base.html" %} {% block contents %} <video name='demo' controls autoplay width='50%' height='40%'> <source src="{{media}}/sample.mp4" type="video/mp4"></source> </video> {% endblock %}views.py:
def index(request): return render(request, "app/videoplay.html", {'media': MEDIA_ROOT})我从settings.py导入了 MEDIA_ROOT ,这是绝对的媒体目录的路径。
I imported MEDIA_ROOT from settings.py and it is absolute path of media directory.
开发环境:
browser: chrome django:1.6.1 python:2.7静态和媒体目录关系:
mysite/ static/ sample.mp4 media/ sample.mp4 templates/ .... views.py ....推荐答案
您在文件URL的开头缺少斜杠,并且不需要将MEDIA_ROOT传递到上下文中,使用您在设置文件中设置的{{STATIC_URL}}模板变量。
You're missing the slash at the start of the file URL, and you don't need to pass the MEDIA_ROOT into the context, use the {{ STATIC_URL }} template variable that you set in your settings file.
从下面的评论中,您的MEDIA_ROOT设置是django将存储媒体文件(用户上传)的位置。 django将在STATIC_ROOT中查找静态文件(您的js / css / images等)。
To clarify from the comments below, your MEDIA_ROOT setting is where django will store media files (user uploaded). The STATIC_ROOT is where django will look for static files (your js/css/images etc).
STATIC_URL 模板中使用 MEDIA_URL 设置。它们将被设置为 STATIC_URL = / static / 和 MEDIA_URL = / media / 之类的东西,它们由django传递到模板,因此在执行以下操作时:
The STATIC_URL and MEDIA_URL settings are used in the template. They will be set to something like STATIC_URL = "/static/" and MEDIA_URL = "/media/" and they are passed to the template by django so when you do:
<img src="{{ STATIC_URL }}sample.jpg" />或
<source src="{{ MEDIA_URL }}sample.mp4" type="video/mp4"></source>它将 {{STATIC_URL}} 替换为 / static / ,所以最终得到 / static / sample.jpg 作为django的src网址用于从STATIC_ROOT中提取文件。
it replaces {{ STATIC_URL}} with "/static/" so you end up with "/static/sample.jpg" as the src url which django uses to fetch your file from the STATIC_ROOT.
