这将为您的项目添加 DotNetOpenAuth .NET Core 库,为集成身份验证功能提供支持。

使用 DotNetOpenAuth .NET Core 的基本代码示例

下面是一个简单的示例,说明如何使用 DotNetOpenAuth .NET Core 在应用程序中设置 OAuth2 身份验证:

using DotNetOpenAuth.OAuth2;

// Initialize the OAuth2 client
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
IAuthorizationState state = client.ProcessUserAuthorization();
if (state != null && state.IsAuthorized)
{
    // Authorized successfully, now you can access protected resources
}
using DotNetOpenAuth.OAuth2;

// Initialize the OAuth2 client
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
IAuthorizationState state = client.ProcessUserAuthorization();
if (state != null && state.IsAuthorized)
{
    // Authorized successfully, now you can access protected resources
}
Imports DotNetOpenAuth.OAuth2

' Initialize the OAuth2 client
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
Private state As IAuthorizationState = client.ProcessUserAuthorization()
If state IsNot Nothing AndAlso state.IsAuthorized Then
	' Authorized successfully, now you can access protected resources
End If
VB   C#

该代码片段使用 DotNetOpenAuth .NET Core 设置 OAuth2 客户端,连接授权服务器并处理用户授权。

DotNetOpenAuth .NET Core 的实施功能

整合 OpenID Connect

要使用 DotNetOpenAuth .NET Core 集成 OpenID Connect,您可以遵循以下基本方法:

using DotNetOpenAuth.OAuth2;

// Configure the OpenID Connect client
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
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
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)
VB   C#

这段代码将配置 OpenID Connect 客户端,并将用户重定向到 OpenID 提供商的身份验证页面。

处理访问令牌

下面介绍如何使用 DotNetOpenAuth .NET Core 处理访问令牌:

// After user is authenticated, process the authorization response
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 user is authenticated, process the authorization response
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 user is authenticated, process the authorization response
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
VB   C#

该代码段处理用户授权响应,以检索和使用访问令牌。

刷新令牌

要在令牌过期时刷新令牌,请使用以下代码:

// 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
VB   C#

这段代码会检查当前令牌是否已过期,并尝试刷新它。

注销代币

如果需要撤销令牌,请按下图执行:

// 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
VB   C#

该代码段撤销了授权,从而有效地使访问令牌失效。

定制令牌请求

定制令牌请求以满足特定需求,如添加额外参数:

// Customize the token request
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
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
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
VB   C#

这段代码为令牌请求添加了自定义参数,这对于处理授权服务器的特定要求非常有用。

DotNetOpenAuth .NET Core 与 IronPDF

IronPDF 是一个综合库,允许开发人员在 .NET 环境中创建、读取和处理 PDF 文件。它特别适用于从 HTML 或直接从 URL 生成 PDF,这对于报告、生成发票或只是以静态格式存储网页都非常有用。与 DotNetOpenAuth .NET Core 集成后,它能确保这些功能的安全性,只有经过验证的用户才能访问。

将 IronPDF 与 DotNetOpenAuth .NET Core 合并的用例

将 IronPDF 与 DotNetOpenAuth .NET Core 合并的一个实际用例是在一个 Web 应用程序中,通过身份验证的用户需要生成和下载个性化报告。例如,想象一下用户登录到您的应用程序并以 PDF 格式访问其财务报告的场景。DotNetOpenAuth 可确保用户通过正确的身份验证和授权来访问他们的文档,而 IronPDF 则处理这些个性化 PDF 的创建和交付。

用例代码示例

让我们来看一个完整的代码示例,演示如何实现这一功能。我们将在 .NET Core 中创建一个简单的 Web API,用于验证用户身份,然后使用 IronPDF 生成 PDF 报告:

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
VB   C#

在本例中,我们使用 `[授权]属性,以确保只有通过身份验证的用户才能访问 PDF 生成端点。IronPDF 中的 "ChromePdfRenderer "类用于从 HTML 内容创建 PDF,在本例中,该内容是用用户名动态个性化的。
