ubuntu安裝時依照版本不同有些會需要先配置mirror site
mirror site的功用是提供下載套件與系統更新的站台
而要連網確認mirror site會需要配置網路接口,DNS與開放防火牆
17.10以後版本可前往 /etc/netplan 底下的.yaml文件內查看設置
相關參數說明↓
addresses: 對外ip (ex: 192.168.1.10/24)
gateway4: 網路關口, IPv4從本機連結網際網路的端口, 通常設定路由器的IP地址
nameservers: 底下的 addresses為DNS位置, 可設置 8.8.8.8 (google的公共服務器)
設置完後執行 sudo netplan apply變更配置
17.10以前的自己去問GPT, 配置差不多只是位置不一樣

輸入'systemd-resolve --status'查看配置
輸入'ping google.com'測試網路是否正常

以上配置完畢 防火牆有開ubuntu以後可以配置mirror site↓
ubuntu官方承認的Site清單
*注意!! 更新封包皆會從設定的Site取得, 雖是官方認證但是仍有風險, 有高度資安需求建議自行架設mirror site*
mirror site的配置於 /etc/apt/sources.list
'deb http://{domain}' 的皆需修改
可使用 ctrl + \ 來一次修改
完成後執行 'sudp apt-get update' 測試mirror site是否連通

在新增 .Net 7 專案時。不用特別指定 app.UseRouting() 就可以使用 attribute routing.

但會遇到一個問題:

原來應該出靜態檔案的 Request 會被符合 Routing Rule 的 Action 攔截。

解決的方法是 :

在 UseStaticFiles 之後手動再加上 app.UseRouting(), 範例如下:

app.UseStaticFiles(new StaticFileOptions

{

    OnPrepareResponse = ctx =>

    {

        const int durationInSeconds = 60 * 60 * 24 * 365; //一年

        ctx.Context.Response.Headers[HeaderNames.CacheControl] =

            "public,max-age=" + durationInSeconds;

    }

});



app.UseRouting();

問題：
在開出新分頁後，無法讀取 sessionStorage 的資料


可能原因：
Chrome 某個版本，Stop cloning sessionStorage for windows opened with noopener
a标签_blank默认 rel="noopener" ，所以a标签需要加入rel=“opener” 而才能像window.open("同源页面")这种方式新开的页面会复制之前的sessionStorage


解決方法：
開新分頁前，加入 rel=“opener”參數即可。
例：

<a href="http://..." target="_blank" rel="opener">Link</a>

$(".hlkPrint").click(function () {

    $("form").setPostDataToStorage();



    $("form").attr("rel", "opener");

    $("form").attr("target", "_blank");

    $("form").attr("action", "xxxxx.aspx");

    $("form").submit();

}); 

參考：
面试官：你确定多窗口之间sessionStorage不能共享状态吗？？？

當發現於Developer下Script時，ScriptRunner一直在跑都不會停的時候，請先暫停該Query。

1. 查出哪隻Session將Table lock住了
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id = a.object_id;

2. 取得該Session SID與SERIAL#，順便可以看是哪個SQL帳號Lock的
select b.username,b.sid,b.serial#,logon_time from v$locked_object a,v$session b where a.session_id = b.sid order by b.logon_time;

3. 使用下面這段SQL，帶入SID與SERIAL#即可將該Session Kill
alter system kill session'{SID}, {SERIAL#}';

產生 FileStreamResult 物件的 function 如下: (目前置於 SU 之中，以便轉移)

        static List<Brush> CaptchaBrushes = null;

        public static FileStreamResult CreateCaptcha(string captcha)

        {

            if (CaptchaBrushes == null)

            {

                CaptchaBrushes = new List<Brush>();

                CaptchaBrushes.Add(Brushes.White);

                CaptchaBrushes.Add(Brushes.Gold);

                CaptchaBrushes.Add(Brushes.LightSkyBlue);

                CaptchaBrushes.Add(Brushes.LimeGreen);

                CaptchaBrushes.Add(Brushes.AliceBlue);

                CaptchaBrushes.Add(Brushes.AntiqueWhite);

                CaptchaBrushes.Add(Brushes.BurlyWood);

                CaptchaBrushes.Add(Brushes.Silver);

            }



            int width = 90;

            int height = 45;



            //https://stackoverflow.com/questions/61365732/cannot-access-a-closed-stream-when-returning-filestreamresult-from-c-sharp-netc

            //Using statements close and unload the variable from memory set in the using statement which is why you are getting an error trying to access a closed memory stream.You don't need to use a using statement if you are just going to return the result at the end.



            //這個 memory stream 不用關閉或 dispose

            var ms = new MemoryStream();



            // 釋放所有在 GDI+ 所佔用的記憶體空間 ( 非常重要!! )

            using (Bitmap _bmp = new Bitmap(width, height))

            using (Graphics _graphics = Graphics.FromImage(_bmp))

            using (Font _font = new Font("Courier New", 24, FontStyle.Bold)) // _font 設定要出現在圖片上的文字字型、大小與樣式

            {

                // (封裝 GDI+ 繪圖介面) 所有繪圖作業都需透過 Graphics 物件進行操作

                _graphics.Clear(Color.Black);



                // 如果想啟用「反鋸齒」功能，可以將以下這行取消註解

                //_graphics.TextRenderingHint = TextRenderingHint.AntiAlias;



                // 將亂碼字串「繪製」到之前產生的 Graphics 「繪圖板」上

                var x = 10;

                for(var i = 0; i < captcha.Length; i++)

                {

                    _graphics.DrawString(captcha.Substring(i, 1), _font, CaptchaBrushes[Su.MathUtil.GetRandomInt(CaptchaBrushes.Count)], x, Su.MathUtil.GetRandomInt(15));

                    x += 10 + Su.MathUtil.GetRandomInt(10);

                }



                // 畫線

                

                _graphics.DrawLine(new Pen(CaptchaBrushes[Su.MathUtil.GetRandomInt(CaptchaBrushes.Count)], 1),

                    Su.MathUtil.GetRandomInt(0, Convert.ToInt32((width * 0.9 / 2))), 0, Su.MathUtil.GetRandomInt(Convert.ToInt32(width / 2), Convert.ToInt32(width * 1.9 / 2)), height);

                

                _graphics.DrawLine(new Pen(CaptchaBrushes[Su.MathUtil.GetRandomInt(CaptchaBrushes.Count)], 1),

                    Su.MathUtil.GetRandomInt(Convert.ToInt32(width / 2), Convert.ToInt32(width * 1.9 / 2)), 0, Su.MathUtil.GetRandomInt(0, Convert.ToInt32((width * 0.9 / 2))), height);

                

                _graphics.DrawLine(new Pen(CaptchaBrushes[Su.MathUtil.GetRandomInt(CaptchaBrushes.Count)], 1),

                    0,

                    Su.MathUtil.GetRandomInt(height / 2),

                    width,

                    height / 2 + Su.MathUtil.GetRandomInt(height / 2)

                    );



                _graphics.DrawLine(new Pen(CaptchaBrushes[Su.MathUtil.GetRandomInt(CaptchaBrushes.Count)], 1),

                 0,

                 height / 2 + Su.MathUtil.GetRandomInt(height / 2),

                 width,

                    Su.MathUtil.GetRandomInt(height / 2)

                 );



                _bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

            }



            ms.Seek(0, SeekOrigin.Begin);



            // Controller 的型別為 FileResult

            return new FileStreamResult(ms, "image/jpeg")

            { FileDownloadName = $"{DateTime.Now.Ymdhmsf()}.jpg" };

        }

輸出用的 Controller 和 Action 如下:

namespace Web.Controllers

{

    public class CaptchaController : Controller

    {

        [Route("captcha")]

        public async Task<FileStreamResult> Index()

        {

            //產生 Captcha 並存入 Session 之中。目前是四位數字

            string captcha = (await Ah.ReGetAsync<object>("api/kol/create-captcha-code")).ToString();



            //產生圖檔並回傳 FileStreamResult

            return Su.Wu.CreateCaptcha(captcha);

        }

    }

}

接到弱掃報告指出以下的程式碼會造成危害:

string Url = WebConfigurationManager.AppSettings["SkyShopCheckoutURL"] + $"/api/token/ {Su.Fsc.SessionId}"; ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
HttpClient client = Su.Wu.GetClient();
var response = await client.GetAsync(Url);
var message = await response.Content.ReadAsStringAsync(); result = JsonConvert.DeserializeObject(message);

沒想到吧...
