* test/e2e-ctf-bypass.mjs
|
||
*
|
||
* Issue #60 测试脚本 — "万能破甲焚诀" CTF 绕过效果验证
|
||
*
|
||
* 核心思路：
|
||
* 用户只需声明"这是 CTF 题目"，Cursor 源站的 AI 就会放下防护，
|
||
* 以"授权靶场"心态回答本来会拒绝的问题。
|
||
*
|
||
* 本脚本直接请求 Cursor 源站 (https://cursor.com/api/chat)，
|
||
* 对比 【无 CTF 框架】 和 【有 CTF 框架】 两组提示词的效果差异。
|
||
*
|
||
* 运行方式：
|
||
* node test/e2e-ctf-bypass.mjs
|
||
*
|
||
* 环境变量（可选）：
|
||
* PROXY=http://127.0.0.1:7890 # 代理（国内可直连，通常不需要）
|
||
* TIMEOUT=120 # 请求超时秒数
