每次都找不到，在這裡記錄一下。

進入 Official Account Manager 之後，點右上方的 Setting，在左側選單有 Message API

 
 

使用 putty 連線到 ubuntu 後，使用 vi 編輯設定檔，註解會變成深藍色，幾乎看不到

 
要改顏色可以用以下的指令:
vi ~/.vimrc

加入一行
colorscheme desert
 
結果:
 
 

錯誤代碼 NETSDK1064
找不到套件 BouncyCastle.Cryptography，版本 2.3.0。該套件可能因 NuGet restore 還原而刪除，或是可能因為路徑長度上限的限制，而讓 NuGet restore 可能只有部分完成所致。

試了好久總算可以正常打開
工具>>NuGet套件管理員>>套件管理員設定


重起就可以正常跑了!!!
 

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

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"

 

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.

Restful 的 API 範例，比較特別的是取得單一筆資料時，不是用一般常見的 {id} 而是用 get?id=xxx 的方式，以避免 XXS 的功擊。(不要把原網頁中的參數拼入 API 網址，要改用 Query String 的方式傳給 API)

PromiseAll: async function (array) {

    let taskList = [];

    let propList = [];

    for (let obj of array) {

        for (let prop in obj) {

            taskList.push(obj[prop]);

            propList.push(prop);

        }

    }

    let resp = await Promise.all(taskList);

    let result = {};

    let counter = 0;

    for (let prop of propList) {

        result[prop] = resp[counter];

        counter += 1;

    }

    return result;

}

PromiseAll 是將API一次發送並接收回傳值的工具
使用方法範例:

const taskList = [{

    adPosition : BannerPositionDataService.GetList(),

    big : BannerDataService.GetList(100),

    smallTop : BannerDataService.GetOne(200),

    smallBottom : BannerDataService.GetOne(300),

    section2 : BannerDataService.GetList(400),

    section3 : BannerDataService.GetList(500),

    section4 : BannerDataService.GetList(600),

    recommends : ProductDataService.GetRndList()

}];



let resps = await UJ.PromiseAll(taskList);

要特別記得TaskList中的Method不需要做await,不然就沒有意義了

DeepBinding: function (vueData, data) {



    if (Array.isArray(data)) {

        if (!Array.isArray(vueData)) {

            vueData = [];

        } else {

            vueData.splice(0);

        }

        for (let prop in data) {

            vueData.push(data[prop]);

        }

    }

    else if (typeof (data) === 'object') {

        if (Object.keys(data).length === 0) {

            return;

        }

        for (let prop in data) {

            if (vueData[prop] === undefined || data[prop] === null ||

                (!Array.isArray(vueData[prop] && vueData !== null && typeof (data) !== 'object'))) {

                vueData[prop] = data[prop];

            } else {

                this.DeepBinding(vueData[prop], data[prop]);

            }

        }

    } else {

        vueData = data;

    }

}

在資料回傳後要Binding到Vue Data上面或是任意Object的Property上可以使用這個,
不使用DeepBinding是因為瀏覽器版本限制,這個方式不受瀏覽器版本限制,但是只有提供一階,需要多階請自行改寫.
使用方法範例:

UJ.DeepBinding(this, resp);

這邊的this代表的是Vue的Data
 

改寫成可輸入多參數，效能也比較好的版本。
以下為測試碼，請自行依照專案需求做修改。
