Django中文件的上传

项目整体目录结构

目录结构.png

在settings中配置STATICFILES_DIRS

STATIC_URL = '/static/'
# 设置静态文件存放的物理目录
STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')]

2.在settings中配置MEDIA_ROOT

# 设置文件上传路径
MEDIA_ROOT = os.path.join(BASE_DIR,'static/media')

3.在TEMPLATES中创建上传文件页面

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

        <input type="submit" value="提交">

    </form>
</body>
</html>

注意：form标签的属性中添加 enctype="multipart/form-data" ,否则后台获取file为空
4.在url中配置处理函数的路径

from django.conf.urls import url
from django.contrib import admin
from django.urls import path
from bookstore import views

urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^show',views.show),
    url(r'^upload',views.upload_handle)
]

5.在views中处理上传逻辑：

from django.conf import settings
from django.http import HttpResponse
from django.shortcuts import render,redirect

def show(request):
    if request.method =="GET":
        return render(request,'upload.html')

def upload_handle(request):
    """
    处理上传图片
    :param request:
    :return:
    """
    # 1.获取上传的文件
    file = request.FILES.get('myFile')
    # 创建一个文件
    save_path = '%s/%s'%(settings.MEDIA_ROOT,file.name)
    # 2.获取上传文件内容并写入到创建的文件中
    with open(save_path,'wb') as f:
        for content in file.chunks():
            f.write(content)

    # 写入到数据库保存上传记录
    
    # 返回
    return HttpResponse("上传成功")
