以下是一個簡單的範例，展示如何使用 DotNetOpenAuth .NET Core 在您的應用程式中設置 OAuth2 認證：

using DotNetOpenAuth.OAuth2;

// Initialize the OAuth2 client with the authorization server details
var client = new WebServerClient(new AuthorizationServerDescription
{
    TokenEndpoint = new Uri("https://your-auth-server.com/token"),
    AuthorizationEndpoint = new Uri("https://your-auth-server.com/authorize")
}, "your-client-id", "your-client-secret");

// Start the authentication process and get the authorization state
IAuthorizationState state = client.ProcessUserAuthorization();
if (state != null && state.IsAuthorized)
{
    // Authorized successfully, now you can access protected resources
}

using DotNetOpenAuth.OAuth2;

// Initialize the OAuth2 client with the authorization server details
var client = new WebServerClient(new AuthorizationServerDescription
{
    TokenEndpoint = new Uri("https://your-auth-server.com/token"),
    AuthorizationEndpoint = new Uri("https://your-auth-server.com/authorize")
}, "your-client-id", "your-client-secret");

// Start the authentication process and get the authorization state
IAuthorizationState state = client.ProcessUserAuthorization();
if (state != null && state.IsAuthorized)
{
    // Authorized successfully, now you can access protected resources
}

Imports DotNetOpenAuth.OAuth2

' Initialize the OAuth2 client with the authorization server details
Private client = New WebServerClient(New AuthorizationServerDescription With {
	.TokenEndpoint = New Uri("https://your-auth-server.com/token"),
	.AuthorizationEndpoint = New Uri("https://your-auth-server.com/authorize")
}, "your-client-id", "your-client-secret")

' Start the authentication process and get the authorization state
Private state As IAuthorizationState = client.ProcessUserAuthorization()
If state IsNot Nothing AndAlso state.IsAuthorized Then
	' Authorized successfully, now you can access protected resources
End If

Imports DotNetOpenAuth.OAuth2

' Initialize the OAuth2 client with the authorization server details
Private client = New WebServerClient(New AuthorizationServerDescription With {
	.TokenEndpoint = New Uri("https://your-auth-server.com/token"),
	.AuthorizationEndpoint = New Uri("https://your-auth-server.com/authorize")
}, "your-client-id", "your-client-secret")

' Start the authentication process and get the authorization state
Private state As IAuthorizationState = client.ProcessUserAuthorization()
If state IsNot Nothing AndAlso state.IsAuthorized Then
	' Authorized successfully, now you can access protected resources
End If

此程式碼片段設置了一個使用 DotNetOpenAuth .NET Core 的 OAuth2 使用者端，連接到授權伺服器，並處理使用者的授權。

實現 DotNetOpenAuth .NET Core 的功能

整合 OpenID Connect

要使用 DotNetOpenAuth .NET Core 整合 OpenID Connect，您可以按照此基本方法進行：

using DotNetOpenAuth.OAuth2;

// Configure the OpenID Connect client with authority details
var openIdClient = new WebServerClient(new AuthorizationServerDescription
{
    TokenEndpoint = new Uri("https://your-openid-provider.com/token"),
    AuthorizationEndpoint = new Uri("https://your-openid-provider.com/authorize")
}, "your-client-id");

// Redirect user for authentication
Uri authUri = openIdClient.GetAuthorizationRequestUri("openid email profile");
Response.Redirect(authUri.AbsoluteUri);

using DotNetOpenAuth.OAuth2;

// Configure the OpenID Connect client with authority details
var openIdClient = new WebServerClient(new AuthorizationServerDescription
{
    TokenEndpoint = new Uri("https://your-openid-provider.com/token"),
    AuthorizationEndpoint = new Uri("https://your-openid-provider.com/authorize")
}, "your-client-id");

// Redirect user for authentication
Uri authUri = openIdClient.GetAuthorizationRequestUri("openid email profile");
Response.Redirect(authUri.AbsoluteUri);

Imports DotNetOpenAuth.OAuth2

' Configure the OpenID Connect client with authority details
Private openIdClient = New WebServerClient(New AuthorizationServerDescription With {
	.TokenEndpoint = New Uri("https://your-openid-provider.com/token"),
	.AuthorizationEndpoint = New Uri("https://your-openid-provider.com/authorize")
}, "your-client-id")

' Redirect user for authentication
Private authUri As Uri = openIdClient.GetAuthorizationRequestUri("openid email profile")
Response.Redirect(authUri.AbsoluteUri)

Imports DotNetOpenAuth.OAuth2

' Configure the OpenID Connect client with authority details
Private openIdClient = New WebServerClient(New AuthorizationServerDescription With {
	.TokenEndpoint = New Uri("https://your-openid-provider.com/token"),
	.AuthorizationEndpoint = New Uri("https://your-openid-provider.com/authorize")
}, "your-client-id")

' Redirect user for authentication
Private authUri As Uri = openIdClient.GetAuthorizationRequestUri("openid email profile")
Response.Redirect(authUri.AbsoluteUri)

此程式碼配置了一個 OpenID Connect 使用者端，並將使用者重定向到 OpenID 提供者的認證頁面。

處理存取令牌

以下是您如何使用 DotNetOpenAuth .NET Core 處理存取令牌：

// After the user is authenticated, process the authorization response to retrieve the token
IAuthorizationState authState = openIdClient.ProcessUserAuthorization();
if (authState != null && authState.IsAuthorized)
{
    // Access token is available, and you can use it to make authenticated requests
    string accessToken = authState.AccessToken;
}

// After the user is authenticated, process the authorization response to retrieve the token
IAuthorizationState authState = openIdClient.ProcessUserAuthorization();
if (authState != null && authState.IsAuthorized)
{
    // Access token is available, and you can use it to make authenticated requests
    string accessToken = authState.AccessToken;
}

' After the user is authenticated, process the authorization response to retrieve the token
Dim authState As IAuthorizationState = openIdClient.ProcessUserAuthorization()
If authState IsNot Nothing AndAlso authState.IsAuthorized Then
	' Access token is available, and you can use it to make authenticated requests
	Dim accessToken As String = authState.AccessToken
End If

' After the user is authenticated, process the authorization response to retrieve the token
Dim authState As IAuthorizationState = openIdClient.ProcessUserAuthorization()
If authState IsNot Nothing AndAlso authState.IsAuthorized Then
	' Access token is available, and you can use it to make authenticated requests
	Dim accessToken As String = authState.AccessToken
End If

此程式碼片段處理使用者授權響應以檢索和使用存取令牌。

刷新令牌

要在令牌過期時刷新它們，請使用以下程式碼：

// Check if the access token is expired and refresh it
if (authState.AccessTokenExpirationUtc <= DateTime.UtcNow)
{
    if (openIdClient.RefreshAuthorization(authState))
    {
        // Token refreshed successfully
    }
}

// Check if the access token is expired and refresh it
if (authState.AccessTokenExpirationUtc <= DateTime.UtcNow)
{
    if (openIdClient.RefreshAuthorization(authState))
    {
        // Token refreshed successfully
    }
}

' Check if the access token is expired and refresh it
If authState.AccessTokenExpirationUtc <= DateTime.UtcNow Then
	If openIdClient.RefreshAuthorization(authState) Then
		' Token refreshed successfully
	End If
End If

' Check if the access token is expired and refresh it
If authState.AccessTokenExpirationUtc <= DateTime.UtcNow Then
	If openIdClient.RefreshAuthorization(authState) Then
		' Token refreshed successfully
	End If
End If

此程式碼檢查當前令牌是否過期並嘗試刷新它。

撤銷令牌

如果您需要撤銷令牌，請按照下面的顯示進行實施：

// Revoke the access token
bool success = openIdClient.RevokeAuthorization(authState);
if (success)
{
    // Token revoked successfully
}

// Revoke the access token
bool success = openIdClient.RevokeAuthorization(authState);
if (success)
{
    // Token revoked successfully
}

' Revoke the access token
Dim success As Boolean = openIdClient.RevokeAuthorization(authState)
If success Then
	' Token revoked successfully
End If

' Revoke the access token
Dim success As Boolean = openIdClient.RevokeAuthorization(authState)
If success Then
	' Token revoked successfully
End If

此程式碼片段撤銷授權，有效地使存取令牌失效。

自訂令牌請求

要為特定需求自訂令牌請求，例如加入額外參數：

// Customize the token request with additional parameters
var additionalParams = new Dictionary<string, string>
{
    {"custom_parameter", "value"}
};
IAuthorizationState customizedState = openIdClient.ProcessUserAuthorization(additionalParams);
if (customizedState != null && customizedState.IsAuthorized)
{
    // Token request customized and processed successfully
}

// Customize the token request with additional parameters
var additionalParams = new Dictionary<string, string>
{
    {"custom_parameter", "value"}
};
IAuthorizationState customizedState = openIdClient.ProcessUserAuthorization(additionalParams);
if (customizedState != null && customizedState.IsAuthorized)
{
    // Token request customized and processed successfully
}

' Customize the token request with additional parameters
Dim additionalParams = New Dictionary(Of String, String) From {
	{"custom_parameter", "value"}
}
Dim customizedState As IAuthorizationState = openIdClient.ProcessUserAuthorization(additionalParams)
If customizedState IsNot Nothing AndAlso customizedState.IsAuthorized Then
	' Token request customized and processed successfully
End If

' Customize the token request with additional parameters
Dim additionalParams = New Dictionary(Of String, String) From {
	{"custom_parameter", "value"}
}
Dim customizedState As IAuthorizationState = openIdClient.ProcessUserAuthorization(additionalParams)
If customizedState IsNot Nothing AndAlso customizedState.IsAuthorized Then
	' Token request customized and processed successfully
End If

此程式碼向令牌請求中新增了自訂參數，這對處理授權伺服器的特定需求很有用。

DotNetOpenAuth .NET Core with IronPDF

IronPDF 是一個全面的程式庫，允許開發人員在 .NET 環境中建立、閱讀和操作 PDF 檔案。它特別適用於從 HTML 或直接從 URL 生成 PDF，這對於報告、生成發票或只是將網頁儲存為靜態格式非常有用。當與 DotNetOpenAuth .NET Core 整合後，它確保這些功能僅對經過身份驗證的使用者安全且可存取。

將 IronPDF 與 DotNetOpenAuth .NET Core 合併的使用案例

將 IronPDF 與 DotNetOpenAuth .NET Core 合併的一個實際使用案例是在網頁應用程式中，經過身份驗證的使用者需要生成和下載個性化報告。例如，想像一下場景，使用者登錄您的應用程式並以PDF格式存取他們的財務報告。 DotNetOpenAuth 確保使用者得到正確的身份驗證和授權以存取其文件，而 IronPDF 則負責建立和傳遞這些個性化的PDF檔。

使用案例的程式碼範例

讓我們看看一個完整的程式碼範例，展示如何執行此操作。我們將在 .NET Core 中建立一個簡單的 Web API，認證使用者然後使用 IronPDF 生成 PDF 報告：

using IronPdf;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Authorization;

[Route("api/[controller]")]
[ApiController]
public class ReportController : ControllerBase
{
    [Authorize]
    [HttpGet("download-pdf")]
    public IActionResult DownloadPdfReport()
    {
        // Authentication is handled by DotNetOpenAuth .NET Core
        var currentUser = HttpContext.User.Identity.Name;

        // Generate PDF content using IronPDF
        var Renderer = new ChromePdfRenderer();
        var PDF = Renderer.RenderHtmlAsPdf($"<h1>Report for {currentUser}</h1><p>This is your personalized financial report.</p>");

        // Set file name and content type for the PDF
        var outputFileName = $"Report-{currentUser}.pdf";
        Response.Headers.Add("Content-Disposition", $"attachment; filename={outputFileName}");
        Response.ContentType = "application/pdf";

        // Return the generated PDF file
        return File(PDF.Stream.ToArray(), "application/pdf");
    }
}

using IronPdf;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Authorization;

[Route("api/[controller]")]
[ApiController]
public class ReportController : ControllerBase
{
    [Authorize]
    [HttpGet("download-pdf")]
    public IActionResult DownloadPdfReport()
    {
        // Authentication is handled by DotNetOpenAuth .NET Core
        var currentUser = HttpContext.User.Identity.Name;

        // Generate PDF content using IronPDF
        var Renderer = new ChromePdfRenderer();
        var PDF = Renderer.RenderHtmlAsPdf($"<h1>Report for {currentUser}</h1><p>This is your personalized financial report.</p>");

        // Set file name and content type for the PDF
        var outputFileName = $"Report-{currentUser}.pdf";
        Response.Headers.Add("Content-Disposition", $"attachment; filename={outputFileName}");
        Response.ContentType = "application/pdf";

        // Return the generated PDF file
        return File(PDF.Stream.ToArray(), "application/pdf");
    }
}

Imports IronPdf
Imports Microsoft.AspNetCore.Mvc
Imports Microsoft.AspNetCore.Authorization

<Route("api/[controller]")>
<ApiController>
Public Class ReportController
	Inherits ControllerBase

	<Authorize>
	<HttpGet("download-pdf")>
	Public Function DownloadPdfReport() As IActionResult
		' Authentication is handled by DotNetOpenAuth .NET Core
		Dim currentUser = HttpContext.User.Identity.Name

		' Generate PDF content using IronPDF
		Dim Renderer = New ChromePdfRenderer()
		Dim PDF = Renderer.RenderHtmlAsPdf($"<h1>Report for {currentUser}</h1><p>This is your personalized financial report.</p>")

		' Set file name and content type for the PDF
		Dim outputFileName = $"Report-{currentUser}.pdf"
		Response.Headers.Add("Content-Disposition", $"attachment; filename={outputFileName}")
		Response.ContentType = "application/pdf"

		' Return the generated PDF file
		Return File(PDF.Stream.ToArray(), "application/pdf")
	End Function
End Class

Imports IronPdf
Imports Microsoft.AspNetCore.Mvc
Imports Microsoft.AspNetCore.Authorization

<Route("api/[controller]")>
<ApiController>
Public Class ReportController
	Inherits ControllerBase

	<Authorize>
	<HttpGet("download-pdf")>
	Public Function DownloadPdfReport() As IActionResult
		' Authentication is handled by DotNetOpenAuth .NET Core
		Dim currentUser = HttpContext.User.Identity.Name

		' Generate PDF content using IronPDF
		Dim Renderer = New ChromePdfRenderer()
		Dim PDF = Renderer.RenderHtmlAsPdf($"<h1>Report for {currentUser}</h1><p>This is your personalized financial report.</p>")

		' Set file name and content type for the PDF
		Dim outputFileName = $"Report-{currentUser}.pdf"
		Response.Headers.Add("Content-Disposition", $"attachment; filename={outputFileName}")
		Response.ContentType = "application/pdf"

		' Return the generated PDF file
		Return File(PDF.Stream.ToArray(), "application/pdf")
	End Function
End Class

在這個例子中，我們使用 [Authorize] 屬性來確保只有經過身份驗證的使用者可以存取 PDF 生成端點。 IronPDF 中的 ChromePdfRenderer 類用來生成 HTML 內容的 PDF，在這個例子中，使用者的姓名會以動態個性化的方式展現在內容中。
