万里长征第二步——django个人博客（第七步 ——上传文件）

标签：

1. 在项目目录下新建一个 ‘uploads’文件夹以保存上传的文件
2. 配置setting.py文件

   MEDIA_URL = ‘/uploads/‘
   
   MEDIA_ROOT = os.path.join(BASE_DIR, ‘uploads‘)  #设置上传的绝对路径

    

3. 配置urls.py文件,设置路由

   from django.conf.urls import url,include
   from django.contrib import admin
   from django.conf import settings
   
   urlpatterns = [
       url(r‘^uploads/(?P<path>.*)$‘,\  
   ‘django.views.static.serve‘,                 {‘document_root‘: settings.MEDIA_ROOT,}),
       url(r‘^admin/‘, admin.site.urls),
       url(r‘^todolist/‘,include(‘todolist.urls‘)),
   ]

    

4. 为富文本编辑器设置上传文件
1. 在APP目录下创建配置文件‘upload.py’

   # -*- coding: utf-8 -*-
   from django.http import HttpResponse
   from django.conf import settings
   from django.views.decorators.csrf import csrf_exempt
   import os
   import uuid
   import json
   import datetime as dt
   
   @csrf_exempt
   def upload_image(request, dir_name):
   ##################
       #  kindeditor图片上传返回数据格式说明：
       # {"error": 1, "message": "出错信息"}
       # {"error": 0, "url": "图片地址"}
       ##################
   result = {"error": 1, "message": "上传出错"}
       files = request.FILES.get("imgFile", None)
   if files:
           result =image_upload(files, dir_name)
   return HttpResponse(json.dumps(result), content_type="application/json")
   
   #目录创建
   def upload_generation_dir(dir_name):
       today = dt.datetime.today()
       dir_name = dir_name + ‘/%d/%d/‘ %(today.year,today.month)
   if not os.path.exists(settings.MEDIA_ROOT + dir_name):
           os.makedirs(settings.MEDIA_ROOT + dir_name)
   return dir_name
   
   # 图片上传
   def image_upload(files, dir_name):
   #允许上传文件类型
   allow_suffix =[‘jpg‘, ‘png‘, ‘jpeg‘, ‘gif‘, ‘bmp‘]
       file_suffix = files.name.split(".")[-1]
   if file_suffix not in allow_suffix:
   return {"error": 1, "message": "图片格式不正确"}
       relative_path_file = upload_generation_dir(dir_name)
       path=os.path.join(settings.MEDIA_ROOT, relative_path_file)
   if not os.path.exists(path): #如果目录不存在创建目录
   os.makedirs(path)
       file_name=str(uuid.uuid1())+"."+file_suffix
       path_file=os.path.join(path, file_name)
       file_url = settings.MEDIA_URL + relative_path_file + file_name
   open(path_file, ‘wb‘).write(files.file.read())
   return {"error": 0, "url": file_url}

    

2. 为富文本编辑器设置路由。urls.py

   from django.conf.urls import url
   from django.contrib import admin
   from blog.views import index
   from django.conf import settings
   from blog.upload import upload_image
   
   urlpatterns = [
       url(r‘^uploads/(?P<path>.*)$‘,‘django.views.static.serve‘,        {‘document_root‘: settings.MEDIA_ROOT,}),
       url(r‘^admin/upload/(?P<dir_name>[^/]+)$‘, upload_image, name=‘upload_image‘),
       url(r‘^admin/‘, admin.site.urls),
       url(r‘^$‘, index, name=‘index‘)
   ]

    

3. 配置KindEditor，在config.js文件中

   KindEditor.ready(function(K) {
      K.create(‘textarea[name="content"]‘, {
             width : "800px",
              height : "200px",
             uploadJson: ‘/admin/upload/kindeditor‘,
      });
   });
