路飞项目篇：simpleui自定义后台管理、路飞课程页面后端及前端页面、视频托管七牛云
[TOC]
1 使用simpleui：自定定义后台管理页面
# 1 之前写的首页，登录，课程都是前台（主站）----》后台管理（运营）---》admin自带的---》不好看，不好用
# 2 自己写后台管理 还是 继续使用django的admin来做还是 基于第三方的美化
-使用第三方的drf+vue的后台管理框架
-咱们继续使用djagno admin---》第三方的美化---》二次开发
# 3 simpleui
-第一步：安装
pip install django-simpleui
-第二步：在app中注册
INSTALLED_APPS = [
'simpleui',
...
]
-第三步：在配置文件中
# 1 指定simpleui默认的主题,指定一个文件名，相对路径就从simpleui的theme目录读
# 2 默认图标
# 3 登录页粒子效果
# 4 定制菜单（重点）
# 5 隐藏显示服务器信息，快速操作
-第四步：在admin中定制
@admin.register(Course)
class CourseAdmin(admin.ModelAdmin):
# 当前页面显示的字段
list_display = ('id', 'name', 'course_type', 'pub_date')
# 增加自定义按钮
actions = ['custom_button',]
def custom_button(self, request, queryset):
print(queryset)
print('按钮被点了')
custom_button.short_description = '测试按钮'
# custom_button.icon = 'fas fa-audio-description'
custom_button.type = 'danger'
custom_button.style = 'color:black;'
-第五步：定制自己的页面
就是写前后端混合，配置好链接即可
-第六步：集成监控大屏
-从网上找一个模板，样式都引入，写模板语法即可

6 课程详情前台
# 课程详情页面
-视频播放---》
-之前用：vue-video-player---》跟node版本兼容性有问题
-现在新的用：vue-core-video-player
#安装视频播放组件：https://www.jianshu.com/p/df4780086a8b
#第一步：安装
cnpm install vue-video-player -S
#第二步：在main.js导入
// vue-video播放器
require('video.js/dist/video-js.css');
require('vue-video-player/src/custom-theme.css');
import VideoPlayer from 'vue-video-player'
Vue.use(VideoPlayer);
# 第三步：在某个vue组件中使用
import {videoPlayer} from 'vue-video-player';
注册
页面某个位置：
<videoPlayer class="video-player vjs-custom-skin"
ref="videoPlayer"
:playsinline="true"
:options="playerOptions"
@play="onPlayerPlay($event)"
@pause="onPlayerPause($event)">
</videoPlayer>
# data中进行播放器的配置
-playerOptions：对象
{
aspectRatio: '16:9', // 将播放器置于流畅模式，并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字（例如"16:9"或"4:3"）
sources: [{ // 播放资源和资源格式
type: "video/mp4",
src: "https://video.pearvideo.com/mp4/short/20170616/cont-1094945-10544594-hd.mp4" //你的视频地址（必填）
}],
}
-onPlayerPlay：视频播放触发
-onPlayerPause：视频暂停触发
6.1 视频托管
# 项目有有些图片，视频，文件。。。
-放在项目的media文件夹下
-第三方托管
-七牛云---》上海的---》国内第一家推崇go语言的---》 go+---》国内镜像--》七牛云
-阿里 oss对象存储
-腾讯 云存储
-自己搭建自己的存储服务器
-fastdfs：https://zhuanlan.zhihu.com/p/372286804
-Minio：选择比较多，有个管理控制台（md---》阿里云机器上搭建的）https://www.cnblogs.com/xujunkai/p/14749165.html
-ceph：大型的存储（小公司不用）
# 七牛云如何用
-手动上传---》创建一个空间（桶）一般不用
-代码上传：两种模式
-后端python上传
-前端js上传
6.2 python代码上传七牛云
# pip install qiniu
from qiniu import Auth, put_file, etag
import qiniu.config
#需要填写你的 Access Key 和 Secret Key
access_key = ''
secret_key = ''
#构建鉴权对象
q = Auth(access_key, secret_key)
#要上传的空间
bucket_name = 'lqz'
#上传后保存的文件名
key = 'my-python-logo.png'
#生成上传 Token，可以指定过期时间等
token = q.upload_token(bucket_name, key, 3600)
#要上传文件的本地路径
localfile = './致命诱惑.mp4'
ret, info = put_file(token, key, localfile, version='v2')
print(info)
assert ret['key'] == key
assert ret['hash'] == etag(localfile)
