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)

ubuntu安裝時依照版本不同有些會需要先配置mirror site
mirror site的功用是提供下載套件與系統更新的站台
而要連網確認mirror site會需要配置網路接口,DNS與開放防火牆
17.10以後版本可前往 /etc/netplan 底下的.yaml文件內查看設置
相關參數說明↓
addresses: 對外ip (ex: 192.168.1.10/24)
gateway4: 網路關口, IPv4從本機連結網際網路的端口, 通常設定路由器的IP地址
nameservers: 底下的 addresses為DNS位置, 可設置 8.8.8.8 (google的公共服務器)
設置完後執行 sudo netplan apply變更配置
17.10以前的自己去問GPT, 配置差不多只是位置不一樣

輸入'systemd-resolve --status'查看配置
輸入'ping google.com'測試網路是否正常

以上配置完畢 防火牆有開ubuntu以後可以配置mirror site↓
ubuntu官方承認的Site清單
*注意!! 更新封包皆會從設定的Site取得, 雖是官方認證但是仍有風險, 有高度資安需求建議自行架設mirror site*
mirror site的配置於 /etc/apt/sources.list
'deb http://{domain}' 的皆需修改
可使用 ctrl + \ 來一次修改
完成後執行 'sudp apt-get update' 測試mirror site是否連通

最近因為資安公司要求，要把 jQuery 升級到最新版
網路查了一下，似乎 3.5 版以後, XSS 才算是改善很多

目前最新版本是 3.7.0，對於原本就使用 3 以上版本專案影響就不大，所有 function 沿用上沒有問題
但是有些舊專案使用 2.X 甚至 1.X 升級到 3.7.0 版之後就會有些功能掛掉

經測試，首當其衝的就是 $(window).load 不能使用，更精準一點應該是 .load() 不能使用
檢查 jquery 過期網頁 https://api.jquery.com/category/deprecated/
發現 .load() 是 1.8 版以後 deprecated，但我 2.2.4 用很久用爽爽
我想應該是 jquery 為了相容問題，一直到跨版本才真的拿掉
也就是 1.X 宣告 deprecated 的功能，到 3.X 才真的移除
(請看附圖)
所以我就鴕鳥的找 1.X  deprecated 然後可能會用的 function 處理
(若有 tag "Removed" 就是已移除，這樣找比較快)

.andSelf()

.live()

.die()

.error()

.load()

.unload()

.size()

.toggle()

大致上專案搜尋字串應該就能處理
但有些可能是其他第三方 jquery物件 例如 jquery-ui ，會用到以上功能
這時可能要去該物件看有無對應升級版

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

            var res1 = await dbct.ProfileEvents.FromSqlRaw("Select top 100 * from ProfileEvent where Name like @name",

                new object[]

                    {

                        new SqlParameter("@name", "%'B%")

                    })

                .ToListAsync();



            //擴充, object to SqlParameter array

            var res2 = await dbct.ProfileEvents.FromSqlRaw("Select top 100 * from ProfileEvent where Name like @name",

                new { name }.ToSqlParamsArray())

                .ToListAsync();



            var res3 = await dbct.ProfileEvents.FromSql($"Select top 100 * from ProfileEvent where Name like {name}")

                .ToListAsync();



            var res4 = await dbct.ProfileEvents.FromSqlInterpolated($"Select top 100 * from ProfileEvent where Name like {name}")

                .ToListAsync();



            return new { res1, res2, res3, res4 };

        }
