1. kindEditor简介:

    KindEditor是一套开源的HTML可视化编辑器,主要用于让用户在网站上获得所见即所得编辑效果。

    主要特点:

1. 体积小,加载速度快,但功能十分丰富。2. 内置自定义range,完美地支持span标记。

3. 基于插件的方式设计,所有功能都是插件,增加自定义和扩展功能非常简单。

4. 修改编辑器风格很容易,只需修改一个CSS文件。

5. 支持大部分主流浏览器,比如IE、Firefox、Safari、Chrome、Opera。

5. XSS过滤特殊标签

处理依赖:

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白名单
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')
# 遍历所有HTML标签
for tag in soup.find_all(recursive=True):
# 判断标签名是否在白名单中
if tag.name not in self.valid_tags:
tag.hidden = True
if tag.name not in ['html', 'body']:
tag.hidden = True
tag.clear()
continue
# 当前标签的所有属性白名单
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)


基于__new__实现单例模式示例:

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from bs4 import BeautifulSoup


class XSSFilter(object):
__instance = None

def __init__(self):
# XSS白名单
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):
"""
单例模式
: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')
# 遍历所有HTML标签
for tag in soup.find_all(recursive=True):
# 判断标签名是否在白名单中
if tag.name not in self.valid_tags:
tag.hidden = True
if tag.name not in ['html', 'body']:
tag.hidden = True
tag.clear()
continue
# 当前标签的所有属性白名单
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/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)


注意:

上方实例中kindEditor向后台提交数据的时候,用的是Form方式;其实,kindEditor也支持Ajex的方式提交,只是当Ajax提交表单时,textarea的value还是空的,需要使用sync()去同步HTML数据!

那么在什么时候去同步,怎么同步?KindEditor同时提供了方法:

afterBlur

编辑器失去焦点(blur)时执行的回调函数。

数据类型: Function

默认值: 无

解决办法:

<script type="text/javascript">
KindEditor.ready(function (K) {
window.editor = K.create('#AContent', {
afterBlur: function () { this.sync(); }
});
});
</script>
