首先下载plupload插件放在static静态文件下面，官方地址:
项目根目录下创建media文件夹用来存放上传的图片，配置settings文件，添加media的文件路径
media_root = os.path.join(base_dir,'media')
先写前端html页面
我要评论{# 引入插件#}
<script src="/static/plupload/moxie.js"></script>
<script src="/static/plupload/plupload.min.js"></script>
{#定义上传图片的按键和显示位置#}
<div class="sbox f_l"><span>上传图片</span>
{% for i in img %}
<img src="{{ i.src }}" alt="">
{% endfor %}
<h2><a id="upload_image_name" src="javascript:;"><input type="button" value="上传图片"></a></h2>
<ul id="image_name_list"></ul>
{# <a href="/" class="read">点击阅读</a>#}
</div>
写前端js语法
{#上传图片#}
<script language="javascript">
var msglayero_upload_image_name;
var index_upload_image_name;
var layer_upload_image_name = 1;
//实例化一个plupload上传对象

browse_button: 'upload_image_name', //触发文件选择对话框的按钮，为那个元素id
url: '/apply/upload/', //服务器端的上传页面地址
flash_swf_url: '/static/plupload/moxie.swf', //swf文件，当需要使用swf方式进行上传时需要配置该参数

{# 删除准备上传的图片#}
$(document).on('click', '.delimg', function () {

</script>
django后台，先创建路由
from django.urls import path,include,re_path
from apply.views import apply
urlpatterns = [
path('index/',apply.index,name='index/'),
path('about/',apply.about,name='about/'),
path('info/',apply.info,name='info/'),
path('list/',apply.list,name='list/'),
path('time/',apply.time,name='time/'),
path('fanyi/',apply.fanyi,name='fanyi/'),
# 上传图片
path('upload/',apply.upload,name='upload/'),
# 删除准备上传的图片
path('delimg/',apply.delimg,name='delimg/'),
]
写方法。
from django.shortcuts import render,redirect,httpresponse
from apply.utils import function
from blacker import settings
import os
import json
from apply.models import *
# 上传图片 def upload(request): img_obj = request.files.get("file") # 通过前台提交过来的图片资源 img_obj.name avatar.jpg range_num = function.range_num(15) # 生成一个15位随机数 print(img_obj.name) img_type = os.path.splitext(img_obj.name)[1] # .jpg 获取文件名后缀 new_img_path = os.path.join(settings.media_root, range_num + img_type) # e:\ftp\code\www\pro\media\add_article_img\676161546271228.jpg #/media/add_article_img/123456.jpg print(new_img_path) img_type2 = img_type.replace(".", "") # png with open(new_img_path, "wb") as f: for line in img_obj: f.write(line) response = { "status": 1, "message": "上传成功", 'file': '/media/'+range_num + img_type+'/', 'file_type': img_type2 } res = media.objects.create(src='/media/'+range_num + img_type+'/') return httpresponse(json.dumps(response)) # 删除正在上传的图片 def delimg(request): print(12) img_path = request.post.get('path') # /media/add_article_img/722264423391172.jpg # img_name = os.path.split(img_path)[-1] # 获取图片名称 722264423391172.jpg img_name = img_path.split('/')[-2] # 获取图片名称 722264423391172.jpg img_new_path = os.path.join(settings.media_root,img_name) # e:\ftp\code\www\pro\media\add_article_img\722264423391172.jpg if not os.remove(img_new_path): response = { "status": 1, "message": "删除成功" } return httpresponse(json.dumps(response))
方法里面有用到function.range_num函数，这是一个封装的产生随机数函数，在应用目录下创建utils文件夹，并创建function.py文件，内容如下
import random
# 随机数
def range_num(num):
# 定义一个种子，从这里面随机拿出一个值，可以是字母
seeds = "1234567890"
# 定义一个空列表，每次循环，将拿到的值，加入列表
random_num = []
# choice函数：每次从seeds拿一个值，加入列表
for i in range(num):
random_num.append(random.choice(seeds))
# 将列表里的值，变成四位字符串
return "" . join(random_num)#5454
上传发现图片上传成功，但是页面不能正常显示；
需要再配置路由，
from django.contrib import admin
from django.urls import path,include,re_path
from apply.views import apply
from django.views.static import serve
from blacker import settings
urlpatterns = [
re_path(r'^media/(?p<path>.*)', serve, {"document_root":settings.media_root}),
path('',apply.index,name='index/'),
path('admin/', admin.site.urls),
path('apply/',include(('apply.urls','apply')))
]
配置后在上传图片如图所示
同时图片已写入数据库，从数据库获取数据并写在页面上；
done。
