python的django写页面上传文件及遇到的问题小结

mynode -> app5 -> urls.py & views.py
| -> templates -> 5 -> upload.html
| -> mynode -> urls.py
| -> media

from django.urls import path
from app5 import views as v5
app_name = 'app5'
urlpatterns = [
    path('upload_file/', v5.upload_file, name = 'upload_file'),
    path('show_upload/', v5.show_upload, name = 'show_upload'),
]

from django.shortcuts import render
from django.http import HttpResponse
import os
def show_upload(request):
  return render(request, '5/upload.html')
def upload_file(request):if request.method == 'POST':
    get_file = request.FILES.get('myfile',None)
    if get_file:
      path = 'media/uploads'
      if not os.path.exists(path):
        os.makedirs(path)
      dest = open(os.path.join(path,get_file.name),'wb+')
      for chunk in get_file:
        dest.write(chunk)
      dest.close()
      return  HttpResponse('上传文件成功！')
    else:
      return HttpResponse('没有上传文件！')
