1. 前台

templates/upload/upload.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Title</title>
</head>
<body>
<form action="/myupload/upload/" method="post" enctype="multipart/form-data">
  {% csrf_token %}
  名字：<input type="text" name="name"><br>
  头像：<input type="file" name="avator"><br>
  <input type="submit" value="提交">
</form>
</body>
</html>

2. 项目设定

settings.py

#添加

ALLOW_UPLOAD = ['jpg', 'png', 'jpeg']

3.app设定

urls.py

from django.contrib import admin
from django.urls import path, register_converter, re_path
from . import views

urlpatterns = [
  path('', views.index, name='index'), # 上传首页
  path('upload/', views.upload), # 上传图片
]

views.py

from django.shortcuts import render
from .models import User,Article
from django.http import HttpResponse
from django.conf import settings
from datetime import datetime
import os
from django.shortcuts import redirect, reverse
import hashlib

# Create your views here.
def index(request):
  users = User.objects.all()
  article = Article.objects.all()
  return render(request, 'myupload/index.html', locals())


def upload(request):
  if request.method == 'GET':
    return render(request, 'myupload/upload.html')
  else:
    name = request.POST.get('name')
    pic = request.FILES.get('avator')

    media_root = settings.MEDIA_ROOT # media
    allow_upload = settings.ALLOW_UPLOAD # ALLOW_UPLOAD
    # path = 'upload/{}/{}/{}/'.format(datetime.now().year, datetime.now().month, datetime.now().day)
    '{:02d}'.format
    path = 'upload/{}/{}/{}/'.format(datetime.now().year,'{:02d}'.format(datetime.now().month), '{:02d}'.format(datetime.now().day))
    full_path = media_root + '/' + path

    # full_path = 'media/upload/2019/12/20'
    if not os.path.exists(full_path): # 判断路径是否存在
      os.makedirs(full_path) # 创建此路径

    # 要不要改图片的名字 生成hash
    # 这块要不要判断图片类型 .jpg .png .jpeg
    # '/../../../myviews/setting.py'
    print(pic)
    print(full_path)
    print(full_path+pic.name)
    if pic.name.split('.')[-1] not in allow_upload:
      return HttpResponse('fail')

    with open(full_path + '/' + pic.name, 'wb') as f:
      for c in pic.chunks(): # 相当于切片
        f.write(c)

    User.objects.create(name=name, avator=path + pic.name)
    return redirect('myupload:index')
