Swashbuckle ASP .NET Core（它如何為開發人員工作）

介紹

Swashbuckle 是 C# .NET CoreNuGet幫助自動記錄所開發的 RESTful Web API 的套件。 在此博客中，我們將探討 Swashbuckle ASP.NET Core 和IronPDF 安裝說明NuGet 套件，可以啟用 ASP.NET Core Web API 的現代應用程式開發。 它們共同實現了一系列功能，而這些功能只需極少量的代碼即可達成。

API 文件頁面使用 swagger UI 工具顯示，該工具使用從 web API 專案生成的 swagger.json。 生成的 JSON 文件遵循開放 API 標準。 Swashbuckle 可作為 NuGet 套件使用。Swashbuckle.AspNetCore安裝和配置後，將自動公開 Swagger JSON。 swagger UI 工具會讀取來自 API 所寫 XML 註解所產生的 swagger JSON 文件。此外，可以透過在專案設定檔中啟用來建立 XML 文件。XML 註解會轉換為 XML 文件，然後從中產生 swagger JSON。 接著，swagger 中介軟體會讀取 JSON 並公開 swagger JSON 端點。

在 .NET Core Web API 專案中的實現

讓我們開始 Web API 專案

dotnet new webapi -n SwashbuckleDemo
cd Swashbuckle
dotnet build
dotnet add package --version 6.5.0 Swashbuckle.AspNetCore
dotnet build
dotnet new webapi -n SwashbuckleDemo
cd Swashbuckle
dotnet build
dotnet add package --version 6.5.0 Swashbuckle.AspNetCore
dotnet build
'INSTANT VB TODO TASK: The following line uses invalid syntax:
'dotnet New webapi -n SwashbuckleDemo cd Swashbuckle dotnet build dotnet add package --version 6.5.0 Swashbuckle.AspNetCore dotnet build
VB   C#

在這裡，我們正在創建一個名為 "SwashbuckleDemo" 的網頁 API 專案，然後從套件管理員控制台中安裝 swashbuckle 套件到 .NET Core Web API 專案。

配置 Swagger 中介軟體

在 Startup.cs 文件中配置 Swagger 服務。

public void ConfigureServices(IServiceCollection services)
{
    // Other service configurations...
    // swagger ui components 
    // Register the Swagger generator
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
        // Optionally, include XML comments for additional information
        var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
        var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
        c.IncludeXmlComments(xmlPath);
    });
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // Other app configurations...
    // Enable middleware to serve generated Swagger as a JSON endpoint.
    app.UseSwagger();
    // Enable static file middleware to serve Swagger UI (HTML, JS, CSS, etc.),
    // specifying the Swagger JSON endpoint.
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
    });
}
public void ConfigureServices(IServiceCollection services)
{
    // Other service configurations...
    // swagger ui components 
    // Register the Swagger generator
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
        // Optionally, include XML comments for additional information
        var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
        var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
        c.IncludeXmlComments(xmlPath);
    });
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    // Other app configurations...
    // Enable middleware to serve generated Swagger as a JSON endpoint.
    app.UseSwagger();
    // Enable static file middleware to serve Swagger UI (HTML, JS, CSS, etc.),
    // specifying the Swagger JSON endpoint.
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
    });
}
Public Sub ConfigureServices(ByVal services As IServiceCollection)
	' Other service configurations...
	' swagger ui components 
	' Register the Swagger generator
	services.AddSwaggerGen(Sub(c)
		c.SwaggerDoc("v1", New OpenApiInfo With {
			.Title = "My API",
			.Version = "v1"
		})
		' Optionally, include XML comments for additional information
		Dim xmlFile = $"{System.Reflection.Assembly.GetExecutingAssembly().GetName().Name}.xml"
		Dim xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile)
		c.IncludeXmlComments(xmlPath)
	End Sub)
End Sub
Public Sub Configure(ByVal app As IApplicationBuilder, ByVal env As IHostingEnvironment)
	' Other app configurations...
	' Enable middleware to serve generated Swagger as a JSON endpoint.
	app.UseSwagger()
	' Enable static file middleware to serve Swagger UI (HTML, JS, CSS, etc.),
	' specifying the Swagger JSON endpoint.
	app.UseSwaggerUI(Sub(c)
		c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1")
	End Sub)
End Sub

上述代碼可在GitHub - Swashbuckle 演示.

Swashbuckle 提供以下功能

Swagger UI 工具

Swashbuckle ASP .NET Core（對開發人員的作用）：圖1 - Swagger UI 工具

Swagger UI 可在 Web API 應用程式的基本 URL 下的「/swagger/index.html」取得。 它列出程式碼中的所有 REST API。 Swagger 生成器讀取 JSON 文件並填充 UI。

Swagger JSON

Swashbuckle.AspNetCore 自動生成 Swagger JSON 檔案，該檔案包含有關 API 結構的信息，包括端點、請求和回應類型等詳細內容。 此 JSON 文件可被支持 Swagger/OpenAPI 標準的其他工具和服務使用。

swagger JSON 檔案可從網路 API 應用程式的基底 URL 的 "/swagger/v1/swagger.json" 取得。

Swashbuckle ASP .NET Core（開發人員如何使用）：圖 2 - swagger JSON 文件。

程式碼註解

開發人員可以在他們的 XML 中使用註釋和屬性ASP.NET核心控制器提供額外資訊以供 Swagger 文件使用。 這包括描述、範例以及其他增強生成的 Swagger 文件的元數據。

配置選項

Swashbuckle.AspNetCore 提供多種配置選項來自訂 Swagger 文件的生成方式。 開發人員可以控制哪些 API 被記錄，配置命名約定，並調整其他設定。

以下是由 Swashbuckle.AspNetCore 提供的一些主要配置選項：

SwaggerGen 選項

c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
c.SwaggerDoc("v1", New OpenApiInfo With {
	.Title = "My API",
	.Version = "v1"
})
VB   C#

此行指定了 Swagger 文檔版本，並包括 API 的標題和版本等元數據。

c.IncludeXmlComments(xmlPath);
c.IncludeXmlComments(xmlPath);
c.IncludeXmlComments(xmlPath)
VB   C#

此選項允許您從程式碼中包含 XML 註釋，以在 Swagger 文件中提供其他資訊。 xmlPath 變數應指向您的 XML 註解文件的位置。

c.DescribeAllParametersInCamelCase();
c.DescribeAllParametersInCamelCase();
c.DescribeAllParametersInCamelCase()
VB   C#

此選項配置Swagger生成器以使用小駝峰命名法作為參數名稱。

c.OperationFilter<CustomOperationFilter>();
c.OperationFilter<CustomOperationFilter>();
c.OperationFilter(Of CustomOperationFilter)()
VB   C#

您可以註冊自定義操作過濾器以修改特定操作的 Swagger 文檔。 CustomOperationFilter 是一個實作 IOperationFilter 的類別。

Swagger UI 選項

c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1")
VB   C#

此行配置 Swagger UI 以顯示文件。 第一個參數是 Swagger JSON 文件的 URL，第二個參數是 API 版本的易讀名稱。

c.RoutePrefix = "swagger";
c.RoutePrefix = "swagger";
c.RoutePrefix = "swagger"
VB   C#

您可以設定 Swagger UI 的路徑前綴。 在此範例中，Swagger UI將可在 /swagger 找到。

c.DocExpansion(DocExpansion.None);
c.DocExpansion(DocExpansion.None);
c.DocExpansion(DocExpansion.None)
VB   C#

此選項控制 Swagger UI 如何顯示 API 文件。 DocExpansion.None 預設會折疊所有操作。

SwaggerOptions

c.SerializeAsV2 = true;
c.SerializeAsV2 = true;
c.SerializeAsV2 = True
VB   C#

此選項指定是否以2.0版本格式序列化Swagger文件(真)或者 3.0 格式(錯誤). 如果您想使用 Swagger 2.0，請將其設為 true。

c.DisplayOperationId();
c.DisplayOperationId();
c.DisplayOperationId()
VB   C#

此選項在Swagger UI中顯示操作ID，這對於調試和理解您的API結構非常有用。

c.OAuthClientId("swagger-ui");
c.OAuthClientId("swagger-ui");
c.OAuthClientId("swagger-ui")
VB   C#

如果您的 API 使用 OAuth 驗證，您可以為 Swagger UI 配置 OAuth 客戶端 ID。

這只是一些可用配置選項的例子。 Swashbuckle.AspNetCore 庫具有高度的可自訂性，你可以通過組合各種選項和篩選器來調整 Swagger 文件以滿足你的特定需求。 請隨時參閱官方文件或您開發環境中的 IntelliSense，以獲取有關可用選項的最新和全面的信息。

介紹 IronPDF

IronPDF 產品概述是來自 的 C# PDF 庫Iron Software 網站用於閱讀和生成 PDF 文件的工具。 它可以輕鬆將含有樣式資訊的格式化文件轉換為PDF。 IronPDF 可以輕鬆從 HTML 內容生成 PDF。 它可以從 URL 下載 HTML 內容，然後生成 PDF。

安裝

通過 NuGet 安裝 IronPDF可以使用NuGet 包管理器詳細資訊或使用Visual Studio 安裝指南套件管理器主控台。

在套件管理器控制台中，輸入指令：

Install-Package IronPdf

使用 Visual Studio

Swashbuckle ASP .NET Core(工作原理（開發人員）)：圖 3 - 在 Visual Studio 中開啟您的專案。 前往「工具」選單，選擇「NuGet 套件管理員」，然後選擇「為方案管理 NuGet 套件」。 在 NuGet 封裝管理介面中，在「瀏覽」標籤下搜尋套件「ironpdf」。 然後選擇並安裝最新版本的IronPDF。

現在，讓我們修改應用程式以新增將網站內容下載為 PDF 文件的功能。
