过滤XSS攻击
安装
npm install xss
使用方法：
var xss = require('xss');
// 使用默认的HTML白名单
console.log(xss('<script>alert("fff");</script>'));
// 指定HTML白名单
var whiteList = {
tag: ['attribute1', 'attribute2'] // 允许的属性
};
console.log(xss('<script>alert("fff");</script>', whiteList));
// 请参考默认的白名单：xss.whiteList
// 过滤指定属性的值，参考默认的 xss.onTagAttr
console.log(xss('<a href="javascript:ooxx">abc</a>', function (tag, attr, value) {
if (tag === 'a' && attr === 'href') {
if (value.substr(0, '11') === 'javascript:') {
return '#';
}
}
}));
测试
npm test
