IIS ARR (reverse proxy) 服務安裝
IIS 如果要使用 reverse proxy server 服務,其實網路上已經有很多文章可以參考
這篇文章只是記錄一下安裝上要注意的事

過去安裝 IIS 套件 可以透過 Web Platform Installer 搜尋下載
但現在 IIS 的 Web Platform Installer 已經不讓人搜尋下載可安裝的套件
所以要直接去微軟網站找相關套件 可以用 IIS ARR 搜尋
https://www.iis.net/downloads/microsoft/application-request-routing
下載 requestRouter_amd64.msi 安裝這個 (3.0版 2021 年以後就沒有更新了)
安裝前,IIS也要預先安裝 URLRewrite 2 套件

安裝很簡單,msi 安裝後,IIS重啟就可以看到
IIS 的主機設定,可以看到 "Application Reuest Routing Cache"  --> 點進後右邊有 Server Proxy Settings
proxy 的設定有一些地方要注意一下,避免未來採到雷

首先 當然先開啟 Enable proxy,下面針對一些要注意的屬性說明一下

1. Time-out : 預設120秒,如果你後端的站台有一些操作可能超過兩分鐘(例如處理報表),這個就調長一點
2. Reverse rewrite host in response header: 這個勾勾預設是開的,他的好意是同站台redirect(302) 到其他網頁,可以覆蓋
    host 讓 client端能跑到正常的網址。但如果你是 redirect 到其他站台,建議把它關掉,不然後端網站如果下
    redirect (302) 到別的站台,他會主動把 redirect網址 host 改為本站 (被雷過,所以要特別記下來)
3. Include TCP port from client IP:  這是一個 X-Forwarded-For 設定,預設是打開,這樣後端主機抓 client 來源 IP就會類似
    "112.121.100.100:443" ,但後端網站在抓 client端IP通常不會管 port number,因此就會造成比對 IP 發生錯誤
    所以建議還是把它關閉
4. Enable disk cache: 預設是勾勾打開,如果後端是靜態網站,例如圖片server,這個打開沒有問題,但如果後端網站是動態網站
    那還是關掉

用vue綁定陣列中項目的值的方式
當一個陣列是原始結構,例:[1,2,3,4,5]
若新增一個項目進去時,一般在html上,v-model會直接綁定那個項目的值,如以下程式

<td v-for="item in list">
      <input type="text" v-model="item" />
</td>

但這樣,在新增項目的input上改變值時,會沒辦法binding到vue值。

這時解決的方式如下,將程式加入index,v-model直接綁定到陣列的索引值,這樣就能改變vue的值

<td v-for="(item, index) in list">
      <input type="text" v-model="list[index]" />
</td>

PS. 若是陣列裡面是物件的結構,使用v-model可直接綁定物件的key值
例:[
 {
    name: "中文",
    value: 1
 },
{
    name: "英文",
    value: 2
 },
{
    name: "日文",
    value: 3
 },
]
<td v-for="item in list">
      <input type="text" v-model="item.name" />
</td>

win server 2022 架設 IIS6 的 SMTP 服務
如果網站需要有一個簡易的SMTP服務,最簡單的方式就是安裝SMTP服務


然後安裝後,記得要去 [服務] 把 [簡易郵件傳送通訊定(SMTP)]  啟動,並且記得要改為"自動啟動" (不然重開機不會啟動)
 
管理SMTP設定,要到這個介面的 IIS6 管理員


But, 如果你是用 win server 2022,就會出現掛掉無法編輯使用的狀況,不知為何win server 2022 會有這個奇怪的bug
請遵照下面步驟修改,就可以正常運作
1. Stop SMTPSVC service [Display Name: Simple Mail Transfer Protocol (SMTP)]
2. Stop IISADMIN service [Display name: IIS Admin Service]
3. Edit "C:\Windows\System32\inetsrv\MetaBase.xml"
4. Find: <IIsSmtpServer Location ="/LM/SmtpSvc/1"
5. Add (Settings are alphabetical): RelayIpList=""
6. Save file
7. Start IISAdmin Service
8. Start SMTPSVC service


開啟IIS6的管理介面後,還要設定一下 允許轉送清單,對於來源IP作管控
 
這樣大致上就可以正常運作

使用 SQL Manage Studio 的匯出和匯入精靈把資料由 MsSql 傳送到 PostgreSql
1. 使用 "具名的 ConnectionString"時,必需在 ODBC Data Sources (32-bit) 中設定,不是  ODBC Data Sources (64-bit)



2. 若日期或數字欄位為 Null 時,會無法轉換,此時必需用 "寫入查詢來指定要傳送的資料"

使用 Dependency Injection 的優缺點
優點:
1. 易於單元測試 
2. ??

缺點:
1. 所有的 function 必需先建立 Interface, 暫麻煩.
2. debug 時必需先 trace 到 interface 再 trace 到實際 implement 的 code.

.net Core環境變數加密方式
簡易執行方式
1. 確定Program.cs有加上Su.Encryption.AesEncryptor.InitAesPaddingEncryptor(secret , iv , encKey , dataRoot)
2. 確定appsettings.json有設定變數,DataRoot、EnvironmentEncKey
3. 先執行一次,會報錯誤,在dataRoot位置會產生一組$"{encKey}.ps1,裡面會放設定環境變數的指令
4. 設定完,記得把 $"{encKey}.ps1檔案刪除
===以上,設定完環境變數===
1. 確定Program.cs有加上Dictionary<string, string> encSetting = Su.Encryption.GetDecryptedSetting
2. 確定appsettings.json有設定變數,DataRoot、EnvironmentEncKey , ShowEncSetting 設定為 false
3. 在 $"{dataRoot}\Config\XXXX_dec.json"設定DBC連線,要注意連線字串要加上  "TrustServerCertificate=true;",因為.net Core一定要藥用SSL連線
4. 設定完之後,在執行一次,會自動產生XXXX.json
5. 刪除XXXX_dec.json
===以上,產生完加密DBC連線
備註,要取回解密連線字串,appsettings.json有設定變數 , ShowEncSetting 設定為 true

概念解說
原本  >> config大多是明文,駭客可以藉由偷到config來知道變數設定,例如  dbc連線資訊、某個APP Key
之後  >> 將重要資訊分成兩段,
appsettings.json  >>  放可公開資訊的設定,例如 DataRoot、EnvironmentEncKey

在環境變數加上一個 由本機產生的隨機變數
讓本機的所有


原理說明
1. .Net Core 啟動時最先執行檔案 Program.cs,在一開頭先檢查本機是否有設定環境變數
緯中用的function Su.Encryption.AesEncryptor.InitAesPaddingEncryptor(secret , iv , encKey , dataRoot)
進階加密標準(英語:Advanced Encryption Standard,縮寫:AES)

沒有的話,會在 dataRoot 這邊產生一個 encKey.ps1的檔案,裡面放有環境變數設定的指令
(encSecretAndIv = Su.Encryption.AesEncryptor.Encrypt(envSecret, envIv, Su.TextFns.GetRandomString(48));
var command = $"[Environment]::SetEnvironmentVariable('{variableName}', '{encSecretAndIv}', 'Machine')";)
(隨機產生48碼亂數,(前32碼為本機專用Secret、後16碼為iv),進行aes加密)
