Django-关于文件上传

一、方式一

def upload(request):
    if request.method == 'GET':
        return render(request,'upload.html')
    else:
        user = request.POST.get('user')
        img = request.FILES.get('img')  #文件对象
        #img是对象（文件大小，文件名称，文件内容）
        print(img.name)
        print(img.size)

        f = open(img.name,'wb')
        for line in img.chunks():
            f.write(line)
        f.close()
        return HttpResponse("....")
		
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <form action="/upload/" method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        <input type="text" name="user"/>
        <div style="position: relative">
            <a>NB上传</a>
            <input type="file" name="img" style="opacity: 0;position: absolute;top: 0;left: 0"/>   
        </div>
        <input type="submit" value="提交"/>
    </form>
</body>
</html>

二、form方式

from django.shortcuts import render,HttpResponse

from django import forms
from django.forms import  fields

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)
        print(obj)
        if obj.is_valid():
            user = obj.cleaned_data['user']
            img = obj.cleaned_data['img']
            print(obj.cleaned_data)
        print(img.name)
        print(img.size)

        f = open(img.name,'wb')
        for line in img.chunks():
            f.write(line)
        f.close()
        return HttpResponse("....")
