JavaScript SDK： https://developer.qiniu.com/kodo/sdk/1239/java

1、安装

pip install qiniu

npm install qiniu-js

2、准备工作

申请空间及获取密钥准备

3、后端获取七牛云token

#######################utils/MyBaseView.py#######################################
from syl_pro.settings import QINIU_ID, QINIU_SECRET
from qiniu import Auth

def qiniu_token():
    # 需要填写你的 Access Key 和 Secret Key
    access_key = QINIU_ID
    secret_key = QINIU_SECRET
    # 构建鉴权对象
    q = Auth(access_key, secret_key)
    # 要上传的空间
    bucket_name = 'syl-feifei'
    # 生成上传 Token，可以指定过期时间等
    token = q.upload_token(bucket_name, expires=3600)
    return token

################################ oauthapp/views.py  #############################
from rest_framework.views import APIView
from rest_framework.response import Response
from utils.MyBaseView import qiniu_token

class QiNiuToken(APIView):

    # permission_classes = [IsAuthenticated]

    def get(self, request):
        token = qiniu_token()
        print(token)
        res_data = {
            "code": 200,
            "msg": "获取token成功",
            "data": {
                "uptoken": token
            }
        }
        return Response(res_data)
#########################  oauthapp/urls.py #########################
from django.urls import path, include
from oauthapp import views

router = DefaultRouter()

urlpatterns = [
    path('qntoken/', views.QiNiuToken.as_view()), # 获取七牛云token
]

4、前端vue调用接口获取 七牛云token，进行文件上传

<template>

   <div>
    <h1>xxx课程</h1>
    <div style="margin: 20px;">
      <label>节标题：</label>
      <input type="text" name=""   v-model="title">
    </div>
    <div style="margin: 20px;" >
      <label>节序号：</label>
      <input type="text" name="" oninput="value=value.replace(/[^\d]/g,'')" v-model="serial_num">
    </div>
    <div style="margin: 20px;">
      <label>课程时长：</label>
      <input type="text" name="" oninput="value=value.replace(/[^\d]/g,'')" v-model="time" >
    </div>
    <div style="margin: 20px;">
      <label>序号：</label>
      <input type="text" name="" oninput="value=value.replace(/[^\d]/g,'')" v-model="seq">
    </div>
     
      <input type="file" name='upFile' id="upFile" @change='changeFile($event)'>
      <input type="button" name="开始上传" value="开始上传" @click='uploadFile()'>
      <img v-if="coverUrl" :src="coverUrl" alt="封面">
      <el-progress :percentage="filePercent"></el-progress>
      <div>{{filePercent}}</div>
      <button @click="add_section()">提交添加信息</button>
      <video

        })
    },

    uploadFile() {
    // 当前VUE中的this 是指向实例，相当于父级，指向指不到子级中。所需需要一个变量 _this 存储this得指向。
      let _this = this       
    // 获取身份的token
      let token = _this.token

    //   实例化七牛云的上传实例
      var observable = qiniu.upload(_this.file, null, token, putExtra, config);

            } 
        },
        // 接收上传错误信息
        error(err) {
          console.log(err)
        },

        // 接收上传完成后的信息
        complete(res) {

             console.log(_this.videoUrl)
             
        }
      };
      // 上传开始
      var subscription = observable.subscribe(observer); 
    },
    // 添加课程 节信息
    add_section(){
