WEB站開啓HTTP監聽端口報錯（HttpListener）

1.端口被佔用,cmd嘗試：netstat -ano
2.權限問題，嘗試如下操作
netsh http delete urlacl url=http://localhost:38080/
netsh http delete urlacl url=http://127.0.0.1:38080/

netsh http add urlacl url=http://localhost:38080/  user=Everyone listen=yes
netsh http add urlacl url=http://127.0.0.1:38080/  user=Everyone listen=yes

netsh advfirewall firewall Add rule name=\"命令行Web訪問38080\" dir=in protocol=tcp localport=38080 action=allow
