我需要一个匹配以下列表中所有XSS有效负载的正则表达式（我没有尝试过滤XSS请求并将URL保存为安全，我试图从中删除有效负载URL本身并将其保存到变量供以后使用）：

我确实设法找到一个并编辑它以匹配一些，但不是全部：

有关示例，请参阅here，它只会匹配<script>，而其中一些不会与它们完全匹配。有没有人有一个更好的正则表达式，只匹配URL的XSS有效负载，或更好的方法来查找XSS有效负载？提前谢谢你。

1 个答案:

答案 0 :(得分：0)

使用内置库找到一种方法：

import urlparse

def find_xss_script(url, query=4):
    data = urlparse.urlparse(url)
    return data[query]

将返回类似：id=24&#x000003c;
