Django实现前台上传并显示图片功能
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')Django实现后台上传并显示图片功能
