xss_test.py文件
from flask import Flask,render_template,request
app = Flask(__name__)
@app.route("/xss",methods=["GET","POST"])
def xss():
text = ""
if request.method == "POST":
text = request.form.get("text")
return render_template("xss.html",text = text)
if __name__ == '__main__':
app.run(debug=True)
xss.html文件路径
xss.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post">
<textarea name="text"></textarea>
<input type="submit" value="提交">

运行flask程序后，在输入框输入<script>alert("hello attack");</script>

如果xss.html代码里没有safe禁止转义的过滤器，会被转义
