LINE Pay款流程： 
reserve Page(紅科) 發送 reserve API => 取得 payment URL => 轉址到 payment URL => LINE Pay 檢查USER狀態 => 轉回confirm page(紅科), 發送 confirm API => DOWN.

付款需要程式： 
reserve API, confirm API:

send request JSON and read return JSON:

#專案： 紅科

由於工作排程往往有數十個甚至百來個 因此需要一個方法能快速備份及移轉到其他 server 的方法
查了一下，好像也只能這樣做

---- 使用指令把全部排程匯出 ----
參考網址
https://msdn.microsoft.com/en-us/library/windows/desktop/bb736357%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396

schtasks /query /XML > all_tasks.xml  
schtasks /query /FO CSV /V >sched_tasks.csv

** xml 比較有用,可以用來匯入到其他server排程，但還要額外處理才能匯入
** csv 只是用來看看目前有哪些排程 可以用來做報表看看
** 這些是全部排程，還要特別處理把 Microsoft 及其他軟體建的排程移除

--------------------------------------------------------------

----如何匯入工作排程到其他 server --------

** 需再寫程式把 all_tasks.xml 拆解成所有排程的單一 xml
   並且生成指令 bat

** 注意 xml 必須是 UTF-16 (unicode) 
   因為 "schtasks /query /XML > all_tasks.xml"產生 xml 是 ansi 

參考網址
https://serverfault.com/questions/325569/how-do-i-import-multiple-tasks-from-a-xml-in-windows-server-2008
** /TN "排程名稱" --- 排程名稱可以是路徑名 
D:\>schtasks.exe /create /TN "\2016JOB\Global\CountryMonthlyStats" /XML "D:\one_task.xml"
** 下面程式碼只是下面程式碼只是參考 還沒實作過
=====================================

var taskXML = new XmlDocument();
taskXML.Load(@"d:\temp\schedtasksBackup.xml");
var batbody = new StringBuilder();

XmlNodeList tasks = taskXML.DocumentElement.GetElementsByTagName("Task");

string strFileName = "d:\\temp\\Task";

for (int i = 0; i < tasks.Count; i++) {
    string onetaskXML = tasks[i].OuterXml;

    //Create the New File. With a little more extra effort
    //you can get the name from a comment above the task -> 應該把註解裡的名稱抓出
    XmlWriter xw = XmlWriter.Create(strFileName + "_" + (i+1) + ".xml");
    batbody.AppendLine(string.Format("schtasks.exe /create /TN \"{0}\" /XML \"{1}\"", "Task " + (i+1) + " Name", strFileName + "_" + (i+1) + ".xml"));

    //Write the XML
    xw.WriteRaw(onetaskXML.ToString());
    xw.Close();

    // Write a bat to import all the tasks
    var batfile = new System.IO.StreamWriter("d:\\temp\\importAllTasks.bat");
    batfile.WriteLine(batbody.ToString());
    batfile.Close();

}

#微軟的排程備份真是有夠爛沒有辦法用介面一鍵搞定

Post 的資料好像會變大, 要改 Web.config

<system.web>

    <httpRuntime requestValidationMode="2.0" maxRequestLength="1024000"/>

</system.web>

程式碼如下:

public string UploadFilesToRemoteUrl(string url, string[] files, NameValueCollection formFields = null)

    {

        string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");



        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        request.ContentType = "multipart/form-data; boundary=" +

                                boundary;

        request.Method = "POST";

        request.KeepAlive = true;



        Stream memStream = new System.IO.MemoryStream();



        var boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +

                                                                boundary + "\r\n");

        var endBoundaryBytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +

                                                                    boundary + "--");





        string formdataTemplate = "\r\n--" + boundary +

                                    "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";



        if (formFields != null)

        {

            foreach (string key in formFields.Keys)

            {

                string formitem = string.Format(formdataTemplate, key, formFields[key]);

                byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);

                memStream.Write(formitembytes, 0, formitembytes.Length);

            }

        }



        string headerTemplate =

            "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n" +

            "Content-Type: application/octet-stream\r\n\r\n";



        for (int i = 0; i < files.Length; i++)

        {

            memStream.Write(boundarybytes, 0, boundarybytes.Length);

            var header = string.Format(headerTemplate, "uplTheFile", files[i]);

            var headerbytes = System.Text.Encoding.UTF8.GetBytes(header);



            memStream.Write(headerbytes, 0, headerbytes.Length);



            using (var fileStream = new FileStream(files[i], FileMode.Open, FileAccess.Read))

            {

                var buffer = new byte[1024];

                var bytesRead = 0;

                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)

                {

                    Response.Write("bytesRead: " + bytesRead.ToString() + "<br>");

                    memStream.Write(buffer, 0, bytesRead);

                }

            }

        }



        memStream.Write(endBoundaryBytes, 0, endBoundaryBytes.Length);

        request.ContentLength = memStream.Length;



        using (Stream requestStream = request.GetRequestStream())

        {

            memStream.Position = 0;

            byte[] tempBuffer = new byte[memStream.Length];

            memStream.Read(tempBuffer, 0, tempBuffer.Length);

            memStream.Close();

            requestStream.Write(tempBuffer, 0, tempBuffer.Length);

        }



        try

        {

            using (var response = request.GetResponse())

            {

                Stream stream2 = response.GetResponseStream();

                StreamReader reader2 = new StreamReader(stream2);

                return reader2.ReadToEnd();

            }

        }

        catch (Exception ex)

        {

            return (ex.ToString());

            throw;

        }

    }

客戶要求
1. 檔案只能放在 Firewall 內的後台用 Web server (Server A).
2. 使用者只能存取 DMZ 的 Web server (Server B).
3. Server B 只能用 HTTP 通過 Firewall 向 Server A 要資料.(i.e.  Server B 不能掛戴 Server A 的目錄成為虛擬目錄)

所以在 Server B 上面建立了一支程式用 HTTP 的方式讀取 Server A 的檔案再寫出去.

例如, http://ServerB/Upload/test.pdf 會讀取 http://ServerA/Upload/test.pdf 再送到 Client 端

namespace WWW.Controllers

{

    public class UploadController : Controller

    {

        // GET: Upload

        public void Index(string Filename)

        {

            //Create a stream for the file

            Stream stream = null;



            //This controls how many bytes to read at a time and send to the client

            int bytesToRead = 10000;



            // Buffer to read bytes in chunk size specified above

            byte[] buffer = new Byte[bytesToRead];



            string url = "http://admin-dev.nanya.bike.idv.tw/newnanyaback/Upload/" + Filename;



            // The number of bytes read

            try

            {

                //Create a WebRequest to get the file

                HttpWebRequest fileReq = (HttpWebRequest)HttpWebRequest.Create(url);



                //Create a response for this request

                HttpWebResponse fileResp = (HttpWebResponse)fileReq.GetResponse();



                if (fileReq.ContentLength > 0)

                    fileResp.ContentLength = fileReq.ContentLength;



                //Get the Stream returned from the response

                stream = fileResp.GetResponseStream();



                // prepare the response to the client. resp is the client Response

                var resp = HttpContext.Response;



                if (Filename.ToLower().EndsWith(".png") ||

                    Filename.ToLower().EndsWith(".jpg") ||

                    Filename.ToLower().EndsWith(".jpeg") ||

                    Filename.ToLower().EndsWith(".gif")

                    )

                {

                    resp.ContentType = "image";

                }

                else

                {

                    //Indicate the type of data being sent

                    resp.ContentType = "application/octet-stream";



                    //Name the file

                    resp.AddHeader("Content-Disposition", "attachment; filename=\"" + HttpUtility.UrlEncode(Filename, Encoding.UTF8) + "\"");

                }



                resp.AddHeader("Content-Length", fileResp.ContentLength.ToString());



                int length;

                do

                {

                    // Verify that the client is connected.

                    if (resp.IsClientConnected)

                    {

                        // Read data into the buffer.

                        length = stream.Read(buffer, 0, bytesToRead);



                        // and write it out to the response's output stream

                        resp.OutputStream.Write(buffer, 0, length);



                        // Flush the data

                        resp.Flush();



                        //Clear the buffer

                        buffer = new Byte[bytesToRead];

                    }

                    else

                    {

                        // cancel the download if client has disconnected

                        length = -1;

                    }

                } while (length > 0); //Repeat until no data is read

            }

            finally

            {

                if (stream != null)

                {

                    //Close the input stream

                    stream.Close();

                }

            }

        }

    }

}

但不是這樣就好了, 在 RouteConfig.cs 中要加上:
            routes.MapRoute(
                name: "Upload",
                url: "Upload/{filename}",
                defaults: new { controller = "Upload", action = "Index", filename = UrlParameter.Optional }
            );

此外在 Web.Config 中也要加上:

  <system.webServer>
    <handlers>
      <add name="UrlRoutingHandler_Upload"
           type="System.Web.Routing.UrlRoutingHandler, 
               System.Web, Version=4.0.0.0, 
               Culture=neutral, 
               PublicKeyToken=b03f5f7f11d50a3a"
           path="/Upload/*"
           verb="GET"/>
    </handlers>
  </system.webServer>

查了一下，原來網址後面多了空白 (%20) , 也就是 ? 前面多了空白
只是exception物件會自作聰明把他濾掉了，反而從 exception log 看不到資料
測試過，userd可以正常看網站，只是server會有不斷 excetion產生，有點煩
網路上雖有一些解法，但我想還是要求下廣告時，要注意網址問題


 

自從 8/1 起 shopunt 就呈現奇怪的現象



基本上是每日半夜12點流量暴增 (peak 到 80mb)，然後逐漸下降，到了 5~6點又慢慢爬升，直到 10 點以後就驟降

基本上，網站沒有掛掉，沒有太多Exception，LB兩台server的流量很平均，Server Diff 查也沒有過多的Session
可以排除被攻擊的可能性

為了找問題，只好從 IIS Log著手......
1. 首先，查詢12點有甚麼網頁或網址異常多點擊數，並且比較 11 點與 12點兩者差異，結果都沒有任何異常
    卻意外發現有家廣告合作廠商半夜會來抓產品圖，只是這個流量不大，發生點也不是在12點整，不是兇手
2. 起先因為 IIS log 沒有設定 sc-bytes 這個屬性，只有 time-taken 屬性，發現有些圖片 load 的特別久，但還是無法確定問題，所以想說把 sc-bytes 加到 IIS log 再來觀察
3. 加了 sc-bytes 之後的 IIS log，才發現驚人的事實，有幾張圖片竟然高達好幾MB，最大張是放在周年慶的 landing 圖片，竟高達 7.8MB



光1小時，一張圖片吃掉 8.6GB 的量，換算平均值約 13 mb/sec , OMG!
趕緊請設計把圖片換掉

只是這樣，還是有一個奇怪現象，為何半夜12點流量暴增，早上 10 點流量驟減?


這是禍首最大張圖片的點擊數統計(時間是GMT，16是半夜12點, 15是晚上11點)，
就跟流量圖一樣，00~10 點擊數很高，其他時間很低
下面是這張圖片所屬頁面的點擊數統計 (/tch/fixpage.aspx?id=689)



從圖片點擊數看來，我以為是 ISP 某種 transparent proxy cache 發揮作用 (半夜 00~10點關閉 所以流量增加)，
但是看到 fixpage.aspx 的點擊數也是一樣的狀況，我就不知道該怎麼解釋了??
ISP transparent proxy 也會處理 *.aspx ?? 

還是回歸到最基本的原因，網站的廣告曝光量是 00~10點最高??

 

這是 Shopunt 安裝新機器時發生的問題，把他記一下

安裝 黑貓 EGS SERVICE，只要把另一台server C:\EGS 整個目錄 copy 過來
然後跑 C:\EGS\EGS_SETUP.exe  就會跳出 Ezcat Gateway System 視窗
然後只要 "啟動EGS系統" --> windows 服務 就會出現 Ezcat Gateway System Service

這個服務會建立 web service 並監聽 8800 port
http://localhost:8800/egs?cmd=......   就可以存取資料

但要注意的是，由於整個目錄複製過來，會將 sqllite 資料也一併複製過來，這樣會產生一個問題
就是黑貓的配送單號會重複產生，所以新server一定要做一件事

就是 停止EGS服務 -> (系統維護) -> 備份EGS資料 -> 存檔
然後再 還原EGS資料 -> 找出剛剛備份檔  -> (系統資訊) -> 啟動EGS服務
若是看到托運單號是 100 整數  應該就是 reset成功






 

當我們在本地的SQL以 Linked Server方式存取遠端的資料庫，有時會出現這樣的訊息
不允許遠端資料表值函數呼叫
通常是使用 stored procedure 或是 自定義的function 會出現這樣的錯誤
這時候可以有個變通方法，就是使用 OPENQUERY 方法

原寫法 (UNTDB 是 Linked Server的 Name)

mySQL = "Select count(*) as Cnt from [UNTDB].[ShopUNT]..[V_Order_Main] ....



新寫法

mySQL = "Select count(*) as Cnt from [ShopUNT]..[V_Order_Main] ....

mySQL = "Select * from Openquery([UNTDB],'" + mySQL.Replace("'", "''") + "')";

 

最近把 shopunt 網站重啟的Log加上，發現網站有兩次時無預警的重啟
但是沒有exception log, 於是去看系統的 Event log, 發現出現以下的錯誤

原因是另開 Thread 以非同步取得非停售產品的資料時 產生 sql timeout，這時網站就整個 Crash 
約兩分鐘後才重新啟動，我想雙11網站一直Crash應該跟這個有關

改善方式:
1. RebuildNotStopProducDT 要 Try Catch 不要丟 exception 直接寄 mail 就好
2. 資料庫取得 "非停售產品" 有點沒有效率，不忙時至少要跑 4 秒，資料庫一忙就會Timeout，所以應該要把確定下架且不會販售的產品設定為停售 (Is_StopSell = 'Y')，這樣至少少了2000件產品的查詢，可以秒殺

另外 .NET 4.0 有新的物件叫做 Task 可以用來處理非同步程式，也可以處理 exception 狀況，有時間的話再來改看看
 

在做地址的時候用了一個套件(TWZIPCODE)
可以幫你產生下拉霸的郵遞區號選項
很方便(jQuery)
但是在控制他的資料及回傳
又不知道怎樣比較方便直觀了

首先目前也是文字控制的方式是
UWForUNT.WU.ReplaceStringInControl(Me.Page, "#Post_Code#", Post_Code)
直接用 #Post_Code#
再把她取代

直接讓前端讀到值

回傳時 若是用後端控制 不用再傳ajax 或是 塞到別的後端控制項
回傳的方式
UW.WU.GetValueFromQueryStringOrForm("Post_Code")

但是因為之後不讓 Page Load 再次改成預設值
可以加
If Not Me.IsPostBack Then
   UW.WU.GetValueFromQueryStringOrForm("Post_Code")
End If
才不會永遠是預設值
(            $('#twzipcode').twzipcode({
            zipcodeSel: '#Post_Code#', // 此參數會優先於 countySel, districtSel
            countySel: '台北市',
            districtSel: '大安區',
            zipcodeName: 'Post_Code'
            })
)

他如果有包在裡可以直接讀取

另外若是 有一些後端要傳給前端的資料 用response.Write("<script>XXX</script>")
可以直接寫入前端
