目的：在利用QT软件进行登录软件开发时，就想要实现点击按钮跳转到指定网页进行注册以及修改密码等操作，就像QQ客户端那样可以实现网页端修改密码，申请账户等操作；体验地址：html+php+mysql登录界面设计（因需要开启花生壳内网穿透，如需体验可私聊！）
目前已经实现的操作：html界面；html跳转php；php连接数据库；php实现对数据库的增删改查。
注：QT客户端界面部分暂时不做过多介绍，详细界面如：QT仿QQ登录
一、HTML界面及连接数据库

到此为止，登录界面展示完毕，体验地址：html+php+mysql登录界面设计
注：因使用花生壳内网穿透，本机花生壳客户端在线方可体验！可私聊体验！
此外，生成的注册信息存于本机mysql数据库，请合理设置密码！
图标：如下（可自行下载添加，无序一致）
二、如何复现上述界面？
1.下载Apache软件进行安装
安装步骤省略，请自行百度（傻瓜式安装）
软件地址：链接：https://pan.baidu.com/s/13PpwEc-YuEbQYY2iLpXFLQ
提取码：N414
注意：在进行安装时有需要填写端口的步骤，端口号通常设置为：8080
2.打开浏览器查询
浏览器端输入：http://localhost:8080/login/login.html
其他界面仅需将后面文件名字换一下！
另外：在同一局域网内也可用使用ip地址进行查看，进而实现手机端访问该网页！主机ip查询请自行百度！
完整界面已经介绍完毕，以上为本次设计的全部代码以及操作方式，由于Apache无法使用外网访问，接下来主要介绍怎么使用花生壳进行内网穿透，以便进行外网访问！
3.开启花生壳穿透
这里需要开启http服务（需要花6块钱）
开启花生壳服务之后，手机4G以及外网都可进行访问，注：合理需要开启服务才可外网访问，服务关闭，网页无法访问！
