视频文件上传

def upload_video( video ):
    video_name = "%d&&%s%s" % (int(round(time.time() * 1000)), "uservideo", os.path.splitext( video.name )[1])
    image_path = '%s/%s' % (DATA_ROOT, video_name)
    full_path = '%s%s' % (BASE_DIR, image_path)
    try:
        with open(full_path,'wb') as fp:
            for chunk in video.chunks():
                fp.write(chunk)

        os.chmod( full_path, 0666 )

    except Exception as err:

    return image_path

我需要视频文件上的缩略图

def ajax_videoUpload( request ):
    video = request.FILES[request.FILES.keys()[0]]


    videoPath = upload_video( video )
    fullPath = "%s%s" % ( BASE_DIR, videoPath )
    fileExt = os.path.splitext( videoPath )[1] # file extension
    clip = VideoFileClip( fullPath )
    fullPath = string.replace( fullPath, fileExt, ".png" )
    clip.save_frame( fullPath, t = 10.00 )
    thumbnailPath = string.replace( videoPath, fileExt, ".png" )

    return HttpResponse( thumbnailPath )

videoFileClip(fullPath) <--给出错误

此代码在我的本地操作系统 win7、python 2.7 中运行良好，但在服务器中无法运行

我尝试了文件权限和目录权限

对不起，我是韩国人，所以我英语不好......

服务器操作系统 centOS 6，python 2.7.9，django 1.7

如果运行 python 脚本的用户对您正在尝试的操作没有适当的文件系统权限，则您无法更改脚本中的用户权限。

您的方法也存在缺陷，因为您在写入文件后试图授予自己写入权限。它必须以相反的顺序发生才能解决权限被拒绝错误。

听起来是这样，但从您的问题中很难辨别。

我是用手机接电话的，所以请原谅格式。

从命令行使用 chmod 为运行脚本的用户授予权限。

如果没有更多上下文，我猜这个用户是您的 Web 服务器用来删除 root 权限的用户。

您的脚本在本地工作的原因是您正在运行 django 的 runsever 进行开发，它以您的用户身份运行。典型的生产配置使用像 nginx 或 apache 这样的网络服务器，它会更改为安全用户。
