本課程將介紹 Microsoft ASP.NET Core 與分享實務開發經驗：課程內容分別透過commmand line/visual studio 2015 兩種方式建立 Web application，介紹其專案架構差異、Request-pipeline原理、多環境佈署設定與 Dependency Injection 使用方式，並提供簡單程式碼範例，讓與會者快速進入開發情境。此外，每個章節加入實務開發中常見的問題與處理方法，讓開發人員學習與撰寫ASP.NET Core過程更加順暢。 課程大綱 -What's difference between .Net core & .Net Framework -Request pipeline -Middleware -Dependency Injection -Multiple Environments

appsetting.json
web.config

20. 20Presented By: Duran Hsieh
APPSETTING.JSON
• 使用方法 (startup.cs)
• 方法1:
• Configuration.GetSection(“Logging”);
• getValue<T>()
• key()
• value()
• path()
• 方法2:
• 建立 DTO 物件
• 註冊 services.Configure<T> (Configuration.GetSection("logging"));
• 於建構子注入使用

21. 21Presented By: Duran Hsieh
APPSETTING.JSON
• bundleconfig.json
• 相當於過去的 bundleconfig.cs
• 打包、壓縮 javascript 與 css 檔案

22. Request pipeline

REQUEST PIPELINE
Request
Response
Middleware1 Middleware2 Middleware3
logic logic logic
logiclogiclogic

24. 24Presented By: Duran Hsieh
REQUEST PIPELINE
.USE
.RUN

DEPENDENCY INJECTION
• Configuration Objects
• Framework-provided services
• Application Services (Own Services)

35. 35Presented By: Duran Hsieh
DEPENDENCY INJECTION

依情況使用ConfigureServices
方法內註冊

DEPENDENCY INJECTION
• Application Services (Own Services)
建構子內注入ConfigureServices
方法內註冊

38. 38Presented By: Duran Hsieh
DEPENDENCY INJECTION
• Service lifetimes
• Transient
• 每次請求的時候皆會重新建立服務
• Ex: services.AddTransient<IOperationTransient, Operation>();
• Scoped
• 每一次 Request 的時候建立服務，Request 完成後結束
• Ex: services.AddScoped<IOperationScoped, Operation>();
• Singleton
• 第一次請求的時候建立，永久存在
• Ex: services.AddSingleton<IOperationSingleton, Operation>();

39. Multiple Environments

ENVIRONMENT VARIABLE
• 多種開發環境設定
• 因應各種環境有不同的設定
• Development
• QA
• Staging
• Production
• …

41. 41Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
• 多種開發環境設定
• .Net Framework
• web.config 設定參數
• 發佈專案時設定取用檔案
• .Net Core
• Appsetting.json 設定參數
• 環境變數：
• 開發期間：visual studio 內部設定
• 作業系統內設定
• IIS 內參數設定

ENVIRONMENT VARIABLE
操作步驟: 加入各環境 appsetting.json

43. 43Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
.Net Core rc4之前的版本 與 Visual Studio 2015
需加入
否則發佈會遺失檔案

44. 44Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
.Net Core rc4的版本 與 Visual Studio 2017 RC
ANS: 只需要加入專案即可

45. 45Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
• 環境參數設定
• Name: ASPNETCORE_ENVIRONMENT
value : Development
• Name: ASPNETCORE_ENVIRONMENT
value : Staging
• Name: ASPNETCORE_ENVIRONMENT
value : Production

46. 46Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
開發期間：Visual Studio 內部設定

47. 47Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
發佈期間：Windows 內環境變數設定

48. 48Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
發佈期間：IIS 內部設定(1)

49. 49Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
發佈期間：IIS 內部設定(2)

50. 50Presented By: Duran Hsieh
ENVIRONMENT VARIABLE
• (經驗)若沒有設定環境變數，appsetting.{xxx}.json
會自動選擇最後一個使用。
• (經驗) dotnet publish 參數無法指定環境變數。
