這兩天發現的現象。有點不好找錯，所以紀錄一下
因為制式報名頁面使用 ajax form 物件，但 ios 的 safari 一直發生資料有送出，
但是送出後網頁就不跑success後面的 javascript，例如彈跳訊息及導到下個頁面
一開始debug的方向有點猜錯，所以花了點時間找問題
後來才注意到，原來他跑到 ajax error去了，不是 ajax success
直覺可能是 ContentType 的問題，因為預設是 text/html
結果 Response.ContentType 改 application/x-javascript, 就過了  (WTF)
我猜 application/json 應該也沒問題吧
------------------------------
經查證: application/json 比較正確

想到的先列出來.

1. 幫 String 擴充屬性(javascript, .NET)
2. SQL Injection.
3. Cross Site Script Attack.
4. 避免排程未完全執行以及重覆執行.
5. 更新 Cache 與 Lock.
6. SQL Transaction.
 

突然發現 yahoo 不支援 SSL3.0 或 TLS 1.0 了, 要改用 TLS 1.2 才抓的到網頁資料

​

            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

            ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

.Net 4.0 在抓網頁之前先加這兩行, 就可以了. 

.Net 4.5 支援 Tls12, 可以用 

​

            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };

            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

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:

#專案： 紅科

今天遇到客戶的 DB  使用空間滿了. 有  "Active Transaction" 

什麼事十日都不能做, 只好刪掉所有的 Session. 使用的 SQL 如下:

SQL 2012
USE [master];

DECLARE @kill varchar(8000) = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), session_id) + ';'  
FROM sys.dm_exec_sessions
WHERE database_id  = db_id('MyDB')

EXEC(@kill);


​
For MS SQL Server 2000, 2005, 2008
USE master;

DECLARE @kill varchar(8000); SET @kill = '';  
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'  
FROM master..sysprocesses  
WHERE dbid = db_id('MyDB')

EXEC(@kill); 

有時SVN資料夾檔案，簽入簽出會出錯，然後就完全不能用了
跑 cleanup之後，會出現這樣的訊息

Command: Update Error: Previous operation has not finished; run 'cleanup' if it was interrupted Error: Please execute the 'Cleanup' command. Completed!:

其實是SVN有個工作執行沒有結束，若要 kill 掉這個工作，就要使用 sqlite 工具
(SVN 是以 sqlite 來儲存資料)
1. 要下載 sqlite3.exe 主程式放在 SVN root 目錄下
2. 開啟 cmd, 執行 ​ sqlite3.exe .svn/wc.db "select * from work_queue"
3.刪除 work queue qlite3.exe .svn/wc.db "delete from work_queue"
​4. 把 SVN root 下的 sqlite3.exe 移走
