树洞外链远程上传服务器搭建说明

先把代码放出来，其他的有时间再更新（Doge脸）

PHP版服务端脚本

不推荐使用这种方式，推荐使用以后更新的Python脚本。。。

下载后传到服务端，后面自己领悟吧

也可以复制下面代码，都是一样的：

## Python版服务端脚本

Python版脚本更稳定，理论上可上传无限大的文件（PHP文件大小有限制）,所以我更推崇这种服务端。

**安装说明：**

我将以举例的方式说明Python版服务端安装.

1.首先要在服务器上安装Python，推荐2.7版本，其他版本未做兼容性测试。教程大家可以百度

2.安装pip(已安装可以跳过)

[右键这里另存为](https://bootstrap.pypa.io/get-pip.py) 并再终端中运行即可自动下载安装。

3.安装Flask(已安装可以跳过)

执行以下命令自动安装：
<pre class="lang:sh decode:true">sudo pip install Flask</pre>
4.上传、配置远程脚本

比如我有个剩余空间很大的服务器，已经装好了Nginx或其他服务器软件（这是必须的）,绑定的域名是f.aoaoao.me，

网站目录位于/home/wwwroot/default/下。而我想把文件都传到网站的data目录下，并以http://f.aoaoao.me/data/文件名 的形式外链出去。下面就以这种情形说明服务端的配置

先在/home/wwwroot/default/目录下创建data目录。

然后把下面的脚本保存为fileServer.py

或者点击这里直接下载脚本，打开树洞外链的后台，添加上传方案，把自动生成的Token复制下来并填到脚本第13行，保存，然后使用其他方式比如ftp，上传到/home/wwwroot/目录下（注意不要传到default目录下，否则有安全隐患）

然后把终端切换到wwwroot目录，并运行脚本：

cd /home/wwwroot
python fileServer.py

如果看到下面提示，说明脚本运行成功了

其中的8000是默认的服务端端口，如果被占用可以在第97行更改。

验证外网是否能访问，打开f.aoaoao.me:8000如果出现下面提示，就表示远程端口部署成功：

然后上传方案的配置例子：
