如何使用连接令牌连接到 azure 订阅？

Question

我正在尝试连接到我的 azure 订阅，我有一个代码可以让我获得令牌

            var authContext = new AuthenticationContext(string.Format
             ("https://login.windows.net/{0}", tenantId));
            var credential = new ClientCredential(applicationId, password);
            AuthenticationResult token = authContext.AcquireTokenAsync
              ("https://management.core.windows.net/", credential).Result;

            if (token == null)
            {
                Console.WriteLine("Failed to obtain the token");
                return;
            }

从这一步我不知道如何使用 ResourceManagementClient 类来连接...

Answer 1

获得令牌后，您可以像这样使用“ResourceManagementClient”：

    string token = authenticationResult.CreateAuthorizationHeader().Substring("Bearer ".Length);

    Microsoft.Rest.ServiceClientCredentials credentials = new TokenCredentials(token);

    using (var rgClient = new ResourceManagementClient(credentials))
    {
        rgClient.SubscriptionId = "xxxxxxx-xxxxx-xxxxxxxx-xxxxxxx";
        var rgs = rgClient.ResourceGroups.List();
    };

您可以创建自己的“TokenCredentials”类，该类继承自“ServiceClientCredentials”，如下所示：

public class TokenCredentials : ServiceClientCredentials
{

    /// <summary>
    /// The bearer token type, as serialized in an http Authentication header.
    /// </summary>
    private const string BearerTokenType = "Bearer";

    /// <summary>
    /// Gets or sets secure token used to authenticate against Microsoft Azure API. 
    /// No anonymous requests are allowed.
    /// </summary>
    protected ITokenProvider TokenProvider { get; private set; }

    /// <summary>
    /// Initializes a new instance of the <see cref="TokenCredentials"/>
    /// class with the given 'Bearer' token.
    /// </summary>
    /// <param name="token">Valid JSON Web Token (JWT).</param>
    public TokenCredentials(string token)
        : this(token, BearerTokenType)
    {
    }

    /// <summary>
    /// Initializes a new instance of the <see cref="TokenCredentials"/>
    /// class with the given token and token type.
    /// </summary>
    /// <param name="token">Valid JSON Web Token (JWT).</param>
    /// <param name="tokenType">The token type of the given token.</param>
    public TokenCredentials(string token, string tokenType)
        : this(new StringTokenProvider(token, tokenType))
    {
        if (string.IsNullOrEmpty(token))
        {
            throw new ArgumentNullException("token");
        }
        if (string.IsNullOrEmpty(tokenType))
        {
            throw new ArgumentNullException("tokenType");
        }
    }

    /// <summary>
    /// Create an access token credentials object, given an interface to a token source.
    /// </summary>
    /// <param name="tokenProvider">The source of tokens for these credentials.</param>
    public TokenCredentials(ITokenProvider tokenProvider)
    {
        if (tokenProvider == null)
        {
            throw new ArgumentNullException("tokenProvider");
        }

        this.TokenProvider = tokenProvider;
    }

    /// <summary>
    /// Apply the credentials to the HTTP request.
    /// </summary>
    /// <param name="request">The HTTP request.</param>
    /// <param name="cancellationToken">Cancellation token.</param>
    /// <returns>
    /// Task that will complete when processing has completed.
    /// </returns>
    public async override Task ProcessHttpRequestAsync(HttpRequestMessage request,
        CancellationToken cancellationToken)
    {
        if (request == null)
        {
            throw new ArgumentNullException("request");
        }

        if (TokenProvider == null)
        {
            throw new ArgumentNullException("Token provider");
        }

        request.Headers.Authorization = await TokenProvider.GetAuthenticationHeaderAsync(cancellationToken);
        await base.ProcessHttpRequestAsync(request, cancellationToken);
    }
}
