原因：端口为开放，需新建Inbound Rule.
解决办法：
１. 打开 Control Panel -->System and Security --> Windows Firewall ,在左侧菜单中点击Advanced settings
2. 在新打开的Windows Firewall with Advanced Security 窗口中点击左侧Inbound Rules
3. 在右侧点击New Role...
4.在New Inbound Rule Wizard 窗口中
Rule Type :Port,点击Next
Protocal and Ports : Tcp, All local ports,点击Next
Action: Allow the connection,点击Next
Profile: Domain, Private, Public,点击Next
Name:自定义，点击Finish
建好之后再访问，应该没问题了。
