有一类弱联网的手游，他的战斗过程及奖励结果都在客户端，服务器端通过http协议返回一些排名信息等，通过捕获他的http请求和服务器返回数据，就可以在本地计算机架设一个简单的服务器，提供给自己的游戏使用。
例如，游戏大唐好徒弟的PVP模式是需要联网的，根据捕获的http请求做本地服务器。这里用的是Django。
游戏端POST数据给url: idt.17hf.cn/DaTangServer/htdServlet
idt project
$ django-admin startproject idt
$ cd idt
修改idt/settings.py，在其中添加idt到安装的应用，添加'*'到允许的hosts.
添加json模版文件
$ mkdir -p idt/templates/idt
在 idt/templates/idt 目录中添加templates
模版文件1.html

url(r'^$', views.index),
url(r'^DaTangServer/htdServlet$', views.handler),
]
运行idt project
$ python manage.py runserver 0.0.0.0:80
使用该服务器
在win10上新建一点热点，供给iPad使用。
> netsh
> wlan
netsh wlan> set hostednetwork ssid=win10 key=20101010
netsh wlan> set hostednetwork mode=allow
netsh wlan> start hostednetwork
更该win10网络适配器设置，将本地连接或者无线连接共享给win10这个网络。
修改win10的hosts文件
> notepad c:/windows/system32/drivers/etc/hosts
添加记录192.168.100.120 idt.17hf.cn
其中192.168.100.120为本地服务器的IP地址。
使用iPad连接热点网络win10，就可以了。
如何捕获iPad的请求
这里是使用的网络嗅探，利用 ethercap 进行arp欺骗，以捕获iPad游戏大唐好徒弟对服务器的请求，然后利用 curl 发送数据请求并保存服务器返回的JSON数据进行进一步的分析。
到底有什么用
本地的服务器连接更快，PVP时人物的属性值和排名可以调节，缩短了战斗难度，节约了战斗时间。经验证，PVP战斗的奖励是游戏客户端生成的，其奖励的数量或类别不由服务器直接返回决定，所以，对本地服务器的修改，并不能异常的增大奖励结果，要想要丰厚的奖励，只能一次又一次打了。
突破每天PVP只能5次的限制，可以无限刷物质；每日奖励由每日一次提升到每半分钟就有一次。
利用游戏中邮件系统，更改奖励类型btype=0改为btype=1，可以实现奖励无限铜钱和玉如意，不花钱。
