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

# 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)
