Django上传下载文件接口

背景: 使用Django 文件上传下载接口

1.上传文件接口

1.1 上传文件页面 uploads.html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="/upload/" method="post" enctype="multipart/form-data">
        <input type="file" name="file_name">
        <input type="submit">
    </form>
</body>
</html>
1.2 后端接口
import chardet     # 获取上传文件编码格式

class Uploads(View):
   """文件上传 类视图"""
   def get(self, request):
       """表单页面"""
       return render(request, "uploads.html")

   def post(self, request):
       # 获取json文件对象
       obj = request.FILES.get('file_name')
       for chunk in obj.chunks():
           encoding = chardet.detect(chunk)['encoding']
           data = chunk.decode(encoding)
           print(data)
       return HttpResponse('ok')

2.下载文件接口

2.1 下载文件页面 filedown.html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="/filedown/" method="post" enctype="multipart/form-data">
        <input type="file" name="file_name">
        <input type="submit">
    </form>
</body>
</html>

from django.shortcuts import render
from django.views.generic import View
from django.shortcuts import HttpResponse


class FileDown(View, HttpResponse):
    """文件下载 类视图"""
    def get(self, request):
        """表单页面(Test)"""
        return render(request, "filedown.html")

    def post(self, request):
        try:
            file_name = request.POST.get("file_name")
            file_data = ["name: kaka", "age: 18"]
            response.writelines(file_data)
            response['Content-Type'] = 'application/octet-stream'
            response['Content-Disposition'] = 'attachment;filename={0}'.format(file_name)
            return response
        except Exception:
            raise
