6、上傳檔案示例
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title> </head> <body> <div> <h1>文章內容</h1> {{ request.POST.content|safe }} </div> <form method="POST"> <h1>請輸入內容：</h1> {% csrf_token %} <div style="width: 500px; margin: 0 auto;"> <textarea name="content" id="content"></textarea> </div> <input type="submit" value="提交"/> </form> <script src="/static/jquery-1.12.4.js"></script> <script src="/static/plugins/kind-editor/kindeditor-all.js"></script> <script> $(function () { initKindEditor(); }); function initKindEditor() { var a = 'kind'; var kind = KindEditor.create('#content', { width: '100%', // 文字框寬度(可以百分比或畫素) height: '300px', // 文字框高度(只能畫素) minWidth: 200, // 最小寬度（數字） minHeight: 400, // 最小高度（數字） uploadJson: '/kind/upload_img/', extraFileUploadParams: { 'csrfmiddlewaretoken': '{{ csrf_token }}' }, fileManagerJson: '/kind/file_manager/', allowPreviewEmoticons: true, allowImageUpload: true }); } </script> </body> </html>
django - views.py
import os import json import time from django.shortcuts import render from django.shortcuts import HttpResponse def index(request): """ 首頁 :param request: :return: """ return render(request, 'index.html') def upload_img(request): """ 檔案上傳 :param request: :return: """ dic = { 'error': 0, 'url': '/static/imgs/20130809170025.png', 'message': '錯誤了...' } return HttpResponse(json.dumps(dic)) def file_manager(request): """ 檔案管理 :param request: :return: """ dic = {} root_path = '/Users/wupeiqi/PycharmProjects/editors/static/' static_root_path = '/static/' request_path = request.GET.get('path') if request_path: abs_current_dir_path = os.path.join(root_path, request_path) move_up_dir_path = os.path.dirname(request_path.rstrip('/')) dic['moveup_dir_path'] = move_up_dir_path + '/' if move_up_dir_path else move_up_dir_path else: abs_current_dir_path = root_path dic['moveup_dir_path'] = '' dic['current_dir_path'] = request_path dic['current_url'] = os.path.join(static_root_path, request_path) file_list = [] for item in os.listdir(abs_current_dir_path): abs_item_path = os.path.join(abs_current_dir_path, item) a, exts = os.path.splitext(item) is_dir = os.path.isdir(abs_item_path) if is_dir: temp = { 'is_dir': True, 'has_file': True, 'filesize': 0, 'dir_path': '', 'is_photo': False, 'filetype': '', 'filename': item, 'datetime': time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(os.path.getctime(abs_item_path))) } else: temp = { 'is_dir': False, 'has_file': False, 'filesize': os.stat(abs_item_path).st_size, 'dir_path': '', 'is_photo': True if exts.lower() in ['.jpg', '.png', '.jpeg'] else False, 'filetype': exts.lower().strip('.'), 'filename': item, 'datetime': time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(os.path.getctime(abs_item_path))) } file_list.append(temp) dic['file_list'] = file_list return HttpResponse(json.dumps(dic))
7、XSS過濾特殊標籤
處理依賴
pip3 install beautifulsoup4
XSS示例
#!/usr/bin/env python # -*- coding:utf-8 -*- from bs4 import BeautifulSoup class XSSFilter(object): __instance = None def __init__(self): # XSS白名單 self.valid_tags = { "font": ['color', 'size', 'face', 'style'], 'b': [], 'div': [], "span": [], "table": [ 'border', 'cellspacing', 'cellpadding' ], 'th': [ 'colspan', 'rowspan' ], 'td': [ 'colspan', 'rowspan' ], "a": ['href', 'target', 'name'], "img": ['src', 'alt', 'title'], 'p': [ 'align' ], "pre": ['class'], "hr": ['class'], 'strong': [] } @classmethod def instance(cls): if not cls.__instance: obj = cls() cls.__instance = obj return cls.__instance def process(self, content): soup = BeautifulSoup(content, 'lxml') # 遍歷所有HTML標籤 for tag in soup.find_all(recursive=True): # 判斷標籤名是否在白名單中 if tag.name not in self.valid_tags: tag.hidden = True if tag.name not in ['html', 'body']: tag.hidden = True tag.clear() continue # 當前標籤的所有屬性白名單 attr_rules = self.valid_tags[tag.name] keys = list(tag.attrs.keys()) for key in keys: if key not in attr_rules: del tag[key] return soup.renderContents() if __name__ == '__main__': html = """<p class="title"> <b>The Dormouse's story</b> </p> <p class="story"> <div name='root'> Once upon a time there were three little sisters; and their names were <a href="http://example.com/elsie" class="sister c1" style='color:red;background-color:green;' id="link1"><!-- Elsie --></a> <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and <a href="http://example.com/tillie" class="sister" id="link3">Tilffffffffffffflie</a>; and they lived at the bottom of a well. <script>alert(123)</script> </div> </p> <p class="story">...</p>""" v = XSSFilter.instance().process(html) print(v)
基於__new__實現單例模式示例
#!/usr/bin/env python # -*- coding:utf-8 -*- from bs4 import BeautifulSoup class XSSFilter(object): __instance = None def __init__(self): # XSS白名單 self.valid_tags = { "font": ['color', 'size', 'face', 'style'], 'b': [], 'div': [], "span": [], "table": [ 'border', 'cellspacing', 'cellpadding' ], 'th': [ 'colspan', 'rowspan' ], 'td': [ 'colspan', 'rowspan' ], "a": ['href', 'target', 'name'], "img": ['src', 'alt', 'title'], 'p': [ 'align' ], "pre": ['class'], "hr": ['class'], 'strong': [] } def __new__(cls, *args, **kwargs): """ 單例模式 :param cls: :param args: :param kwargs: :return: """ if not cls.__instance: obj = object.__new__(cls, *args, **kwargs) cls.__instance = obj return cls.__instance def process(self, content): soup = BeautifulSoup(content, 'lxml') # 遍歷所有HTML標籤 for tag in soup.find_all(recursive=True): # 判斷標籤名是否在白名單中 if tag.name not in self.valid_tags: tag.hidden = True if tag.name not in ['html', 'body']: tag.hidden = True tag.clear() continue # 當前標籤的所有屬性白名單 attr_rules = self.valid_tags[tag.name] keys = list(tag.attrs.keys()) for key in keys: if key not in attr_rules: del tag[key] return soup.renderContents() if __name__ == '__main__': html = """<p class="title"> <b>The Dormouse's story</b> </p> <p class="story"> <div name='root'> Once upon a time there were three little sisters; and their names were <a href="http://example.com/elsie" class="sister c1" style='color:red;background-color:green;' id="link1"><!-- Elsie --></a> <a href="http://example.com/lacie" class="sister" id="link2">Lacie</a> and <a href="http://example.com/tillie" class="sister" id="link3">Tilffffffffffffflie</a>; and they lived at the bottom of a well. <script>alert(123)</script> </div> </p> <p class="story">...</p>""" obj = XSSFilter() v = obj.process(html) print(v)
