Django之文件上传 


#示例一
# views

def upload(request):
    if request.method == "GET":
        return render(request, "upload.html")
    elif request.method == "POST":
        name = request.POST.get("user")
        img = request.FILES.get("img")
        print("用户名", name)
        print("文件名", img.name)
        print("文件大小", img.size)
        f = open(img.name, "wb")
        for line in img.chunks():
            f.write(line)
        f.close()
        return HttpResponse("...")


# 前端
<!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">
        <input type="text" name="user">
        <input type="file" name="img">
        <input type="submit" value="提交">


    </form>


</body>
</html>

 示例二：（ form组件）

from django.shortcuts import render
from django.shortcuts import 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)
          if obj.is_valid():
             user = obj.cleaned_data['user']
             img = obj.cleaned_data['img']
       
        # 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('...')
