- 文件上传

        - 普通上传

        - 自定义页面上传按钮

        - 基于Form做上传

        - Ajax上传文件？？？？？

一，上传文件

from django.shortcuts import render,redirect, HttpResponse# Create your views here.def update(request):    if request.method == 'GET':        return render(request, 'update.html')    else:        username = request.POST.get('username')        img = request.FILES.get('img')        print(img)        print(username)        file_name = img.name        file_size = img.size        print(file_name, file_size)        f = open(img.name, 'wb')        for line in img.chunks():            f.write(line)        f.close()        return HttpResponse("ok")

    
         
     
          {% csrf_token %}    
          
      
        
       上传       
           
      
    
      
     

基于Form上传

    
         
     
          {% csrf_token %}    {
    { obj.user }}    {
    { obj.img }}    
      
     

from django.shortcuts import render,redirect, HttpResponse# Create your views here.from django import  formsfrom django.forms import fieldsclass Upload(forms.Form):    user = fields.CharField()    img = fields.FileField()def update(request):    if request.method == 'GET':        obj = Upload()        return render(request, 'update.html',{
   'obj':obj})    else:        obj = Upload(request.POST, request.FILES)        if obj.is_valid():            username = obj.cleaned_data['user']            img = obj.cleaned_data['img']            print(img)            print(username)            file_name = img.name            file_size = img.size            print(file_name, file_size)            f = open(img.name, 'wb')            for line in img.chunks():                f.write(line)            f.close()        return HttpResponse("ok")
