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"

前端頁面讀入 API取值工具



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

平行序處理多筆資料

由於匯入91訂單，如果是一筆一筆抓，會耗費比較久的時間
下列寫法是，開兩條 thread 平行處理，可以節省約一半時間

            {

                if (!TMCodeQueues.IsEmpty)

                {

.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)

加密用的物件必需要 dispose 否則會有洩漏密碼或原始資料的可能

請得要用 using 來初始化物件或是 dispose

using(var provider = new SHA512CryptoServiceProvider())
{
byte[] hashvalue2 = provider.ComputeHash(data2ToHash);
return BitConverter.ToString(hashvalue2).Replace("-", "").ToLower();
}

Entity Framework 用起來和 Daper 越來越像了

Entity Framework 提供了 ExecuteSqlRawAsync 和 FromSqlRaw 之後，可以和 Dapper 非常類似的用法。

我們在用 Dapper 時。最常用的就是 sql command 加上一個物件做為參數，就可以執行 CRUD 的動作。

其實用 Entity Framework 的 ExecuteSqlRawAsync 和 FromSqlRaw 也可以逹到幾乎一樣的效果。

ExecuteSqlRawAsync 和 FromSqlRaw 接受的參數是 object array (其實是 Microsoft.Data.SqlClient.SqlParameter 的 array)

所以我們先做一個 Object to Microsoft.Data.SqlClient.SqlParameter Array 的擴充, 可參考: https://gist.github.com/aliozgur/75182b2e9b0a58b83443

不過很奇怪的是，原作者提供的擴充轉出來的會是 System.Data.SqlClient.SqlParameter Array 無法直接使用於 ExecuteSqlRawAsync 和 FromSqlRaw，所以要稍微改一下，把 using System.Data.SqlClient; 改為 using Microsoft.Data.SqlClient; 即可:

另外，我們再自行對 DbContext 做一個擴充如下:

        /// <summary>

        /// 會把物件 Parameter 的各 Property 帶入 SQL 中.

        /// </summary>

        /// <param name="dbct"></param>

        /// <param name="sql"></param>

        /// <param name="parameters"></param>

        /// <returns></returns>

        public static async Task<int> ExecuteParameterSqlAsync(this DbContext dbct, string sql, object parameters)

        {

            return await dbct.Database.ExecuteSqlRawAsync(sql, parameters.ToSqlParamsArray());

        }

最後的結果可以做到以下的效果: (res3 和 res4 是配合 FormattableString 的範例 )

範例程式碼:

        public async Task<object> EfTest()

        {

            var dbct = Ds.NewContext.GvContext;

            var insertSql = @"Insert into ProfileEvent(JobId,[Name],GvShoplineId,LiShoplineId,Phone,Email,LineId,GaClientId)

            Values(@JobId, @Name, null , null , null , @Email, @GaClientId , @GaClientId )";



            //執行 SQL 的原生寫法

            await dbct.Database.ExecuteSqlRawAsync(insertSql, new object[]

            {

                new SqlParameter("@JobId", 10),

                new SqlParameter("@Email", "XX'TT"),

                new SqlParameter("@Name", "AA'BB"),

                new SqlParameter("@GaClientId", "GaClientId"),

            });



            //執行 SQL 的擴充寫法

            await dbct.ExecuteParameterSqlAsync(insertSql, new

            {

                JobId = 10,

                Email = "XX'TT",

                Name = "AA'BB",

                GaClientId = "GaClientId"

            });



            //關於查詢

            string name = "%'B%";

            //原生寫法
