首先下载plupload插件放在static静态文件下面，官方地址:https://www.plupload.com/
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
{# 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 var uploader_upload_image_name = new plupload.Uploader({ 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 silverlight_xap_url: '/static/plupload/Moxie.xap', //silverlight文件，当需要使用silverlight方式进行上传时需要配置该参数 multipart_params: { type: 'image_name', csrfmiddlewaretoken: "{{ csrf_token }}" }, resize: { 800//指定压缩后图片的宽度，如果没有设置该属性则默认为原始图片的宽度 //height: , //指定压缩后图片的高度，如果没有设置该属性则默认为原始图片的高度 //crop: false //是否裁剪图片 }, filters: { max_file_size: '4mb' }, init: { //选择文件 FilesAdded: function (up, files) { //加载层 index_upload_image_name = layer.msg('上传中...', { icon: 16, time: 0, shade: 0.01, success: function (layero, index) { msgLayero_upload_image_name = layero;//是加载层的div } }); //layer_upload_image_name = layer.msg('上传中...', {time: 0}); //不自动关闭 uploader_upload_image_name.start(); }, UploadProgress: function (up, file) { //上传中，显示进度条 var percent = file.percent; msgLayero_upload_image_name.find('.layui-layer-content').html('<i class="layui-layer-ico layui-layer-ico1"></i>上传中...' + percent + '%'); },//单个文件上传完成 FileUploaded: function (up, file, responseObject) { console.log($.parseJSON(responseObject.response));//成功回调函数 {# $('#image_name_list').html('');#} var result = $.parseJSON(responseObject.response); if (result.status == 1) { //上传成功 var htmls = '<li class="img_upload" style="position:relative;margin:0 10px -10px 0;">'; htmls += '<input type="hidden" name="image_name[]" value="' + result.file + '">'; //隐藏域，是为了把图片地址入库。。 htmls += ' <img src="' + result.file + '" width="250" >'; htmls += '<span style="position:absolute;top:-8px;right:-6px;background-color:#fff;border-radius:10px;"><a href=javascript:; class="delImg" data-val="' + result.file + '"> <img src="/static/images/del.png" width="15" /></a></span>'; htmls += '</li>'; {# $('#image_name_list').append(htmls);为可同时上传多张图片，$('#image_name_list').html(htmls);为一次智能上传一张图片#} $('#image_name_list').append(htmls); //上传成功的弹出框 msgLayero_upload_image_name.find('.layui-layer-content').html('<i class="layui-layer-ico layui-layer-ico1"></i>' + result.message); } else { //上传失败的弹出框 msgLayero_upload_image_name.find('.layui-layer-content').html('<i class="layui-layer-ico layui-layer-ico2"></i>' + result.message); } setTimeout(function () { layer.close(index_upload_image_name); }, 2000); }, //全部文件上传完成 UploadComplete: function (up, files) { setTimeout(function () { layer.close(index_upload_image_name); }, 2000); }, //返回错误 Error: function (up, err) { msgLayero_upload_image_name.find('.layui-layer-content').html('<i class="layui-layer-ico layui-layer-ico2"></i>' + result.message); setTimeout(function () { layer.close(index_upload_image_name); }, 2000); } } }); uploader_upload_image_name.init(); {# 删除准备上传的图片#} $(document).on('click', '.delImg', function () { _this = this; $.post('{% url "apply:delimg/" %}', { path: $(_this).data("val"), csrfmiddlewaretoken: "{{ csrf_token }}" }, function (json) { if (json.status == 1) { layer.msg("删除成功", { time: 2000 //2s后自动关闭 }); $(_this).parent().parent().remove(); } else { layer.msg("删除失败", { time: 2000 //2s后自动关闭 }); } }, 'json'); }); </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:ftpcodewwwpromediaadd_article_img676161546271228.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:ftpcodewwwpromediaadd_article_img722264423391172.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。
