概述

当Django在处理文件上传的时候，文件数据被保存在request.FILES
FILES的每个键为下边代码中的name属性的值
1
<input type="file" name="" />
FILES只有在请求的方式为POST且提交的form带有enctype="multipart/form-data"的情况下才会包含数据。否则，FILES将为一个空的类似字典的对象

存储路径

在static目录下创建名为media的目录

1 2	# 配置上传路径 MEDIA_ROOT = os.path.join(BASE_DIR, "static\media")

上传页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>上传文件</title>
</head>
<body>
    <form action="/upfile/" method="post" enctype="multipart/form-data">
        {% csrf_token %}
        <input type="file" name="file">
        <hr>
        <input type="file" name="file">
        <hr>
        <input type="file" name="pic">
        <hr>
        <input type="submit" value="上传">
    </form>
</body>
</html>

视图代码

import os
from django.conf import settings


def upfile(request):
    if request.method == "GET":
        return render(request, 'myApp/upfile.html')
    else:
        response = HttpResponse()

        for key in request.FILES:
            for file in request.FILES.getlist(key):
                fileName = os.path.splitext(file.name)[1][1:]
                allowFile = ["jpg", "png", "jpeg", "gif"]
                if fileName not in allowFile:
                    response.write(file.name + "不符合规则")
                else:
                    upfilePath = os.path.join(settings.MEDIA_ROOT, file.name)
                    with open(upfilePath, "wb") as fp:
                        for c in file.chunks():
                            fp.write(c)
                        response.write(file.name + "上传成功")
        return response
