我正在尝试创建一个可以使用证书身份验证调用Azure Resource Rate API的控制台应用程序。为此,我使用了以下分支GitHub link。
我收到403错误。我已经在我的Azure AD中添加了一个Web应用程序。在清单中,我已使用以下PowerShell命令从我已签名的证书中复制了密钥凭据;
$cert=New-SelfSignedCertificate -Subject "CN=RateCardCert"
-CertStoreLocation "Cert:\CurrentUser\My" -KeyExportPolicy Exportable -KeySpec Signature
$bin = $cert.RawData $base64Value = [System.Convert]::ToBase64String($bin)
$bin = $cert.GetCertHash()
$base64Thumbprint = [System.Convert]::ToBase64String($bin)
$keyid = [System.Guid]::NewGuid().ToString()
$jsonObj = @ customKeyIdentifier=$base64Thumbprint;keyId=$keyid;type="AsymmetricX509Cert";usage="Verify";value=$base64Value}
$keyCredentials=ConvertTo-Json @($jsonObj) | Out-File "keyCredentials.txt"
在de console app中,我使用以下函数来获取令牌;
public static string GetOAuthTokenFromAAD_ByCertificate(string TenanatID, string ClientID, string CertificateName)
{
//Creating the Authentication Context
var authContext = new AuthenticationContext(string.Format("https://login.windows.net/{0}", TenanatID));
//Console.WriteLine("new authContext made");
//Creating the certificate object. This will be used to authenticate
X509Certificate2 cert = null;
//Console.WriteLine("empty 'cert' made, null");
//The Certificate should be already installed in personal store of the current user under
//the context of which the application is running.
X509Store store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
try
{
//Trying to open and fetch the certificate
store.Open(OpenFlags.ReadOnly);
var certCollection = store.Certificates;
var certs = certCollection.Find(X509FindType.FindBySubjectName, CertificateName, false);
//Checking if certificate found
if (certs == null || certs.Count <= 0)
{
//Throwing error if certificate not found
throw new Exception("Certificate " + CertificateName + " not found.");
}
cert = certs[0];
}
finally
{
//Closing the certificate store
store.Close();
}
//Creating Client Assertion Certificate object
var certCred = new ClientAssertionCertificate(ClientID, cert);
//Fetching the actual token for authentication of every request from Azure using the certificate
var token = authContext.AcquireToken("https://management.core.windows.net/", certCred);
//Optional steps if you need more than just a token from Azure AD
//var creds = new TokenCloudCredentials(subscriptionId, token.AccessToken);
//var client = new ResourceManagementClient(creds);
//Returning the token
return token.AccessToken;
}
这是构成URL并放入请求的代码的一部分(xxxx部分由我在Azure AD中注册的webapp的ClientID替换);
//Get the AAD User token to get authorized to make the call to the Usage API
string token = GetOAuthTokenFromAAD_ByCertificate("<MyTenantName.onmicrosoft.com", "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", "RateCardCert");
// Build up the HttpWebRequest
string requestURL = String.Format("{0}/{1}/{2}/{3}",
ConfigurationManager.AppSettings["ARMBillingServiceURL"],
"subscriptions",
ConfigurationManager.AppSettings["SubscriptionID"],
"providers/Microsoft.Commerce/RateCard?api-version=2015-06-01-preview&$filter=OfferDurableId eq 'MS-AZR-0044P' and Currency eq 'EUR' and Locale eq 'nl-NL' and RegionInfo eq 'NL'");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestURL);
// Add the OAuth Authorization header, and Content Type header
request.Headers.Add(HttpRequestHeader.Authorization, "Bearer " + token);
request.ContentType = "application/json";
// Call the RateCard API, dump the output to the console window
try
{
// Call the REST endpoint
Console.WriteLine("Calling RateCard service...");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Console.WriteLine(String.Format("RateCard service response status: {0}", response.StatusDescription));
Stream receiveStream = response.GetResponseStream();
// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
var rateCardResponse = readStream.ReadToEnd();
Console.WriteLine("RateCard stream received. Press ENTER to continue with raw output.");
Console.ReadLine();
Console.WriteLine(rateCardResponse);
Console.WriteLine("Raw output complete. Press ENTER to continue with JSON output.");
Console.ReadLine();
// Convert the Stream to a strongly typed RateCardPayload object.
// You can also walk through this object to manipulate the individuals member objects.
RateCardPayload payload = JsonConvert.DeserializeObject<RateCardPayload>(rateCardResponse);
Console.WriteLine(rateCardResponse.ToString());
response.Close();
readStream.Close();
Console.WriteLine("JSON output complete. Press ENTER to close.");
Console.ReadLine();
}
catch(Exception e)
{
Console.WriteLine(String.Format("{0} \n\n{1}", e.Message, e.InnerException != null ? e.InnerException.Message : ""));
Console.ReadLine();
}
我只是不知道自己要做什么了,我在这里错过了什么?
完全退回控制台:
致电RateCard服务...... 远程服务器返回错误:(403)禁止。
答案 0 :(得分:1)
在评论中聊天后发现了问题:
您正在调用Azure资源管理API,但您仅在Azure服务管理API上授予了权限。您需要将应用程序的服务主体添加到订阅中的角色。找到您的订阅,然后是访问控制(IAM)刀片,然后将您的应用程序添加到该角色。你应该能够找到它的名字。
如果要限制其功能,还可以将服务主体添加到资源组中的角色,甚至是特定资源。
