浅析Django 接收所有文件,前端展示文件（包括视频，文件，图片）ajax请求

(编辑：jimmy 日期: 2024/11/19 浏览：3 次 )

如果是后台上传文件:

setting配置：

STATIC_URL = '/static/'
STATICFILES_DIRS = [
  os.path.join(BASE_DIR, 'static'),
  os.path.join(BASE_DIR, "media"),
]
# Django用户上传的都叫media文件
MEDIA_URL = "/media/"
# media配置，用户上传的文件都默认放在这个文件夹下
MEDIA_ROOT = os.path.join(BASE_DIR, "media")

model的配置：
 img = models.FileField(upload_to="img/",verbose_name="图片")

接收任何文件的前端代码：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
</head>
<body>
<form method="post" action="/upload/" enctype="multipart/form-data" target="ifm1">


  <input type="file" name="file" id="file"/>


  <input type="button" value="提交" onclick="upload()"/>
</form>
<br>
<br>
<br>
<br>
<div>显示图片
  <img id="images">
</div>
<br>
<br>
<br>
<br>
<div>显示路径
  <a href="" id=" rel="external nofollow" imagess">链接</a>
</div>

</div>
<br>
<br>
<br>
<br>
<div>
  {#  href="/static/img/TC代码.txt" rel="external nofollow" #}
  <a id="up"> 下载文件</a>
</div>

<script src="/UploadFiles/2021-04-08/jquery.min.js">

增加任何文件的后端接口代码：


from rest_framework.views import APIView
from django.shortcuts import render, redirect, HttpResponse
from dal import models
from django.http import JsonResponse

class ImageShow(APIView):

  def post(self, request):
    name = str(request.data.get("name"))
    message = {}

    img_url = "/static/img/{}".format(name)

    obj = models.Car.objects.filter(img_url=img_url).first()
    if obj :

      message['code'] = 200
      message['message'] = img_url # 返还路径
      return JsonResponse(message)


下载文件后端：


from django.utils.http import urlquote
from rest_framework.views import APIView
from django.shortcuts import render, redirect, HttpResponse
from dal import models
from django.http import JsonResponse, FileResponse, StreamingHttpResponse


class fileShow(APIView):

  def get(self, request):
    message = {}
    file = open('media/img/TC代码.txt','rb')  # 字符串替换成文件 
    print("file",file.name)
    # file_names = file.name.split('/')[-1]
    # print("file_names",file_names)

    response = FileResponse(file)
    response['Content-Type'] = 'application/octet-stream'

    response['Content-Disposition'] = "attachment;filename={}".format(urlquote("TC代码.txt")) # 字符串替换成下载文件
    print(response)
    return response
