+# 知识点：`session`存在`set-cookie`中
+
+## 解题思路
+
+既然题目已经告诉你了是`session`问题，直接看请求内容
+
+![请求](./img/1.png)
+
+发现response中存在`set-cookie`内容
+
+    set-cookie: sign=ueozvfnqbj; Path=/
+    set-cookie: sessionid=zp9745ys9dywe1zfs1do604nt70athll; expires=Wed, 01 Feb 2023 14:27:00 GMT; HttpOnly; Max-Age=2160
+
+将`sign`和`sessionid`添加到下一个请求中，这题就解决了
