文件存储

项目上线后视频文件一般不保存在我们项目里，一般存放在文件服务器上。文件服务器的带宽都很高，速度很快。

第三方

是把文件对象存储下来。

阿里云 oss

腾讯也有，我们用七牛云不要钱

自己搭建一个文件服务器

fastdfs 文件对象存储

 https://zhuanlan.zhihu.com/p/372286804

七牛云实操

有两种方法

1.直接从前端往云上传，直接返回外链后，提交到接口上，接口在存储。

2.前端上传视频通过后端接口与云交互，云返回外链给后端接口，后端存起来，后端在返回给前端。

官方SDK文档

https://developer.qiniu.com/kodo/1242/python

后端安装

pip install qiniu

按照下面配置

access_key与secret_key查询请从文档里寻找入口

from qiniu import Auth,put_file
#需要填写你的 Access Key 和 Secret Key
access_key = ''
secret_key = ''
q = Auth(access_key, secret_key)


#要上传的空间 就是在七牛云上创建的文件名
bucket_name = 'luffya'
#上传图片或视频后保存的文件名
key = '张红的秘密.mp4'
#生成上传 Token，可以指定token过期时间等
token = q.upload_token(bucket_name, key, 3600)
#要上传文件的本地路径 (要上传文件的路径)
localfile = './9 上午回顾.mp4'
ret, info = put_file(token, key, localfile, version='v2')
print(info)

"""后期可以封装在接口里调用"""

搜索导航栏

前端点击搜索框输入内容搜索发送请求到后端接口

# 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且技术含量高
	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
    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

支付宝支付

准备工作与快速使用

测试环境：
沙箱 https://openhome.alipay.com/develop/sandbox/app

开发时可以使用沙箱环境测试接口，但是无法测试支付宝回调后端接口。需要正式环境。正式环境需要营业执照才能开通。以后使用公司的。

我们使用支付宝SDK来接入但需要第三方模块支持。

密钥工具下载

https://opendocs.alipay.com/common/02kipk

下载完成后生成

生成的公钥配置在支付宝沙箱环境里

第三方模块文档 https://github.com/fzlee/alipay

安装第三方模块

pip install python-alipay-sdk

把在沙箱环境里填写公钥产生的支付宝公钥，和生成公钥的时候有个应用私钥放在项目里固定的格式

支付宝公钥

alipay_public_key.pem

# 按照下面的格式

路由

支付宝回调地址我们在配置文件中设置的是
NOTIFY_URL = BACKEND_URL + "/api/v1/order/success/"
我们需要写一个对应的接口给支付宝进行回调post请求，我们可以修改订单状态。
urlpatterns = [
    path('success/',PaySuccess.as_view())
]
