# [地雷]Chrome/Edge的黑名單的埠號清單

###### tags: `Chrome` `Edge` `瀏覽器`

再測試Vue CLI範例專案部屬實發現
自訂的port號6666在 Chrome/Edge 瀏覽器出現了`ERR_UNSAFE_PORT`的錯誤
*(P.S Edge底層為Chrome)*
但是在FireFox和IE瀏覽器上卻沒有遇到


## 查了一下發現原因是正好踩到了黑名單的埠號清單

## 解決方法

1. ~~換port號~~ (廢話

3. 若要讓 Chrome 瀏覽器可以開放這些限制的 Ports 清單，需要在啟動 Chrome 的時候加入 
`--explicitly-allowed-ports={port號}` 的啟動參數。

例如：
```
C:\Documents and Settings\User\Local Settings\Application Data\Google\Chrome\Application\chrome.exe --explicitly-allowed-ports=6666
```
