文件存储

# 视频文件，存储到某个位置，如果放在自己服务器上
     放在项目的media文件夹
     服务器上线后，用户既要访问接口，又要看视频，都是一个域名和端口
     分开：文件单独放在文件服务器上，文件服务器带宽很高
    
    
# 文件服务器：专门存储文件的服务器
   第三方：
         阿里云：对象存储 oss
         腾讯对象存储
         七牛云存储
   自己搭建：
        fastdfs：文件对象存储  https://zhuanlan.zhihu.com/p/372286804
        minio：
        
        
 # python 如何把文件传到上面
     对应sdk
    
    
 # 七牛云存储 
   使用代码，上传视频
     两种方案
        前端---》传到咱们的服务器----》在服务端再传入到七牛云

七牛云上传文件代码

from qiniu import Auth, put_file, etag
import qiniu.config
#需要填写你的 Access Key 和 Secret Key  在密钥管理里面
access_key = 'UZY7SyoJ5yynG2Kn6iR223aGBNeFlcJJB379Pi9C'
secret_key = 'GZ7yklBR7zX1v3FVvAoyKkVPaMEg0L-9VWRyvnto'
#构建鉴权对象
q = Auth(access_key, secret_key)
#要上传的空间
bucket_name = 'zhuiyueyyds'   # 填创建的空间名
#上传后保存的文件名
key = '嘿嘿嘿.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 = './嘿嘿嘿.png'
ret, info = put_file(token, key, localfile, version='v2')
print(info)

搜索导航栏

前端  Header组件上有个搜索框---》输入内容，搜索----》后端搜索接口

# 所有的商城类的网站，app 都会有搜索功能，其实搜索功能非常复杂切技术含量高
   咱们目前只是简单的搜索，输入课程名字，价格，就可以把实战课搜出来
   输入：课程名字，价格把所有类型课程都搜出来(查询多个表)
   后面会有专门的搜索引擎：分布式全文检索引擎 es做专门的搜索
   
  前端搜索结果呈现页面
