TCP聊天+传输文件服务器服务器套接字v2.6



更改的地方:
主要是客户端界面更改

  1. 注册， 登录界面 （都知道啊， v1.8的改进后输入用户名， 到了主界面的时候才能输入密码， 但现在是直接输入用户名和密码， 然后转为json， 等待回复)
  2. 转到注册 (我用了commandLink)
  3. 记住密码 (checkBox, 如果记住报存到config.json, 下次直接转入登录， 设置为默认)
  4. 两大堡垒 (客户端与服务端两次堡垒， 防止更改客户端数据直接发送的[不符合规范的json数据包], 所以在服务端在识别[用户是否存在] + [账户密码是否正确]的前提下 又增加了[检测用户名密码长度]的规则)
  5. 界面淡入淡出

客户端与服务端两次堡垒， 防止更改客户端数据直接发送的[不符合规范的json数据包], 所以在服务端在识别用户[是否存在] + [账户密码是否正确]的前提下 又增加了[检测用户名密码长度]的规则
