Django文件上传（经典上传方式）

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")
