from django.contrib import adminfrom django.urls import path, register_converter, re_pathfrom . import viewsurlpatterns = [ path('', views.index, name='index'), # 上传首页 path('upload/', views.upload), # 上传图片]

views.py

from django.shortcuts import renderfrom .models import User,Articlefrom django.http import HttpResponsefrom django.conf import settingsfrom datetime import datetimeimport osfrom django.shortcuts import redirect, reverseimport 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')
