经典文件上传方式
创建URL
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from app01 import views
urlpatterns = [
path('admin/', admin.site.urls),
url("upload.html",views.upload),
]
创建一个简易上传页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form action="upload.html" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p><input type="text" name="user"></p>
<p><input type="file" name="img"></p>
<p><input type="submit" value="上传"></p>
</form>
</body>
</html>
创建视图函数进行接收前端传入的文件
from django.shortcuts import render
from django.shortcuts import HttpResponse
from django.shortcuts import redirect
from django import forms
from django.forms import fields
# Create your views here.
class UploadForm(forms.Form):
user=fields.CharField()
img=fields.FileField()
def upload(request):
if request.method=="GET":
return render(request,"upload.html")
else:
obj=UploadForm(request.POST,request.FILES)
if obj.is_valid():
user=obj.cleaned_data["user"]
img=obj.cleaned_data["img"]
# user=request.POST.get("user")
# img=request.FILES.get("img")
# print(request.POST) #获取以POST方式提交的数据
# print(request.FILES) #获取前端提交的文件
# print(img) #获取文件信息
# print(img.name) #获取文件名称
# print(img.size) #获取文件大小
f=open(img.name,"wb")
for line in img.chunks():
f.write(line)
f.close()
return HttpResponse("ok")
