django--文件上传

    <form action="/upload.html/" method="POST" enctype="multipart/form-data">
        {% csrf_token %}
        <input type="text" name="user">
        <div style="position: relative">
            <a >上传</a>
            <input type="file" name="img"  style="opacity:0.2;position: absolute;top:0;left:0;">
        </div>
        <input type="submit" value="提交">
    </form>

把上传标签透明为0，a标签覆盖在上传input标签，可以定义文字或样式　　

python 代码

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:
        # 方法一：
        #obj = UploadForm(request.POST,request.FILES)
       # if obj.is_valid():
           # user = obj.cleaned_data['user']
           # img = obj.cleaned_data['img']
    #方法二：
        print(request.POST)
        print(request.FILES)
        # img是对象（文件大小，文件名称，文件内容…………）
        img = request.FILES.get('img')
        print(img.name)
        print(img.size)
        #把文件内容保存服务器
        f=open(img.name,'wb')
        for line in img.chunks():
            f.write(line)
        return HttpResponse('OK')
