[GO]解決request origin not allowed by Upgrader.CheckOrigin websocket跨域

在gin框架下使用websocket , 如果是跨域請求的時候會報這個錯誤

request origin not allowed by Upgrader.CheckOrigin

 

使用的websocket庫是 "github.com/gorilla/websocket"

需要增加以下代碼：

    upgrader = websocket.Upgrader{
        ReadBufferSize:  1024,
        WriteBufferSize: 1024,
        // 解決跨域問題
        CheckOrigin: func(r *http.Request) bool {
            return true
        },
    }
