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
如果你对python感兴趣，我这有个学习Python基地，里面有很多学习资料，感兴趣的+Q群：688244617MEDIA_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idurl: '/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: {width: 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_pathfrom apply.views import applyurlpatterns = [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,HttpResponsefrom apply.utils import functionfrom blacker import settingsimport osimport jsonfrom 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.jpgrange_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.jpgprint(new_img_path)img_type2 = img_type.replace(".", "") # pngwith 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.jpgimg_name = img_path.split('/')[-2] # 获取图片名称 722264423391172.jpgimg_new_path = os.path.join(settings.MEDIA_ROOT,img_name) # E:\ftp\code\www\pro\media\add_article_img\722264423391172.jpgif 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 adminfrom django.urls import path,include,re_pathfrom apply.views import applyfrom django.views.static import servefrom blacker import settingsurlpatterns = [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；
