Question

Azure Auth存在问题。调用在Azure中托管的WebAPI时未授权401。

以下是基础知识：遵循本教程 - https://github.com/showcases/package-managers

已注册2个申请：

Windows服务
的WebAPI

Windows服务调用STS并成功获取JWT。然后它尝试将该令牌传递给azurewebsites.net上托管的WebAPI。

这是我调用STS的代码（刚刚包含在Auth类中）：

public class AzureAuth
{

    private AuthenticationContext authContext;
    private ClientCredential clientCredential;

    protected string AzureADInstanceName;
    protected string AzureADTenancyName;

    protected string AzureADApplicationClientId;
    protected string AzureADApplicationSecret;
    protected string AzureADApplicationAppId;


    public AzureAuth(string azureADInstanceName, string azureADTenancyName, string azureADApplicationClientId, string azureADApplicationSecret, string azureADApplicationAppId)
    {
        this.AzureADInstanceName = azureADInstanceName;
        this.AzureADTenancyName = azureADTenancyName;
        this.AzureADApplicationClientId = azureADApplicationClientId;
        this.AzureADApplicationSecret = azureADApplicationSecret;
        this.AzureADApplicationAppId = azureADApplicationAppId;

        string authority = string.Format(CultureInfo.InvariantCulture, AzureADInstanceName, AzureADTenancyName);
        this.authContext = new AuthenticationContext(authority);
        this.clientCredential = new ClientCredential(AzureADApplicationClientId, AzureADApplicationSecret);
    }

    public async Task ExecuteGetWithAADAutToken<T>(Action<AuthenticationResult> AfterAuthAction)
    {
        AuthenticationResult result = null;
        try
        {
            result = await authContext.AcquireTokenAsync(this.AzureADApplicationAppId, this.clientCredential);
            AfterAuthAction(result);
        }
        catch (Exception ex)
        {
            throw;
        }
    }
}

然后我使用Auth类和AuthResult来调用WebApi：

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri(getEndPointUri);
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
    client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", res.AccessToken);

    HttpResponseMessage response = await client.GetAsync("/api/field");

    if (response.IsSuccessStatusCode)
    {
        var resultStringJSON = await response.Content.ReadAsStringAsync();
        Console.WriteLine(resultStringJSON);
    }
    else
    {
        var resulterrorStringJSON = await response.Content.ReadAsStringAsync();
        Console.WriteLine(resulterrorStringJSON);
    }
}

HttpResponseMessage响应正在提供未经授权的

我用fiddler来获取请求和响应：

GET https://xxxxxxxx.azurewebsites.net/api/someapi HTTP/1.1
Accept: application/json
Authorization: Bearer XXXXXXXXX
Host: xxxxxx.azurewebsites.net


HTTP/1.1 401 Unauthorized
Content-Length: 0
Server: Microsoft-IIS/8.0
WWW-Authenticate: Bearer realm="xxxxxxx.azurewebsites.net"
X-Powered-By: ASP.NET

请帮忙吗？

我怀疑的主要问题是在Azure中，AAD应用程序无法访问Web API应用程序。我试图通过用户添加它，但当我以用户搜索该应用程序时，它无法找到它。已注册的应用程序位于不同的Azure AD目录中。

您是否偶然在门户网站中启用了身份验证/授权？当他们在同一个Web应用程序中同时使用集成的身份验证/授权和OWIN Azure AD身份验证中间件时，有些人遇到了类似的问题。设置应用程序的正确方法是使用其中一种，因为它们目前不能很好地协同工作。
