这是一种简单的做法不需要用到数据库

setting.py中需要配置3个地方

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'upLoadImg',

]

TEMPLATES = [

    {

        'BACKEND': 'django.template.backends.django.DjangoTemplates',

        'DIRS': [os.path.join(BASE_DIR, "templates")],

        'APP_DIRS': True,

        'OPTIONS': {

            'context_processors': [

                'django.template.context_processors.debug',

                'django.template.context_processors.request',

                'django.contrib.auth.context_processors.auth',

                'django.contrib.messages.context_processors.messages',

            ],

        },

    },

]

STATIC_URL = '/static/'

STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')]

MEDIA_ROOT=os.path.join(BASE_DIR,'static/media')

urls.py

from django.contrib import admin

from django.urls import path

# from myImg.uploadPic import views

from upLoadImg import views

urlpatterns = [

    path('admin/', admin.site.urls),

    path('uploadPic/',views.uploadPic),

    path('uploadHandle',views.uploadHandle)

]

views.py

from django.shortcuts import render

from django.conf import settings

from django.http import HttpRequest,HttpResponse

import os

# Create your views here.

def uploadPic(request):

    return render(request,'myImg/uploadPic.html')

def uploadHandle(request):

    if request.method == "POST":

        f1 = request.FILES['pic1']

        fname = os.path.join(settings.MEDIA_ROOT,f1.name)

        with open(fname,'wb+') as pic:

            for c in f1.chunks():

                pic.write(c)

        return HttpResponse('<img src="/static/media/%s" width="500" height="500" alt="图片无法显示"/>'%f1.name) # 这里不给width和height会按图片本身分辨率显示

    else:

        return HttpResponse("error")

    #下面这个是直接显示路径

    # pic1 = request.FILES['pic1']

    # picName=os.path.join(settings.MEDIA_ROOT,pic1.name)

    # return HttpResponse(picName)#/Users/liuwei/myImg/static/media/6.png

    #file:///Users/liuwei/myImg/static/media/6.png

upLoadPic.html

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>Title</title>

</head>

<body>

<form action="/uploadHandle" method="post" enctype="multipart/form-data">

    {% csrf_token %}

<input type="file" name="pic1">

    <br>

    <input type="submit" value="上传">

</form>

</body>

</html>

那进入myImg/目录运行

python3 manage.py runserver

在浏览器打开

http://127.0.0.1:8000/uploadPic/

碰到几个问题：

1. 图片显示不了那是因为setting .py中没有

STATICFILES_DIRS=[os.path.join(BASE_DIR,'static')]

2.上传不了是因为要用wb+ ，这个百度就可以了

with open(fname,'wb+') as pic:
