我有一个小程序在尝试获取Azure德国云的访问令牌时失败
public static String generateAccessToken(AzureAccount accountValue) throws MalformedURLException, InterruptedException,
ExecutionException, ServiceUnavailableException {
AuthenticationContext context;
ExecutorService service = null;
try {
String tenantId = accountValue.getTenant();
String ClientID = accountValue.getClient();
String secretKey = accountValue.getKey();
service = Executors.newFixedThreadPool(1);
context = new AuthenticationContext(
"https://login.microsoftonline.de/" + tenantId
+ "/oauth2/authorize", false,
service);
ClientCredential cred = new ClientCredential(ClientID, secretKey);
Future<AuthenticationResult> future =
context.acquireToken("https://management.microsoftazure.de", cred,
null);
AuthenticationResult authenticationResult = future.get();
if (authenticationResult == null) {
throw new ServiceUnavailableException("authentication result was null");
}
System.out.println("Bearer " + authenticationResult.getAccessToken());
return "Bearer " + authenticationResult.getAccessToken();
}
finally {
service.shutdown();
}
}
该代码适用于Azure General Cloud，但对于德国云而言失败。
这是stackTrace

看起来它正在寻找一些我不知道的证书文件。有没有人对此有任何想法？
还有一种方法可以使用Azure Java SDK获取Azure Access令牌，这样我就不必单独进行REST API调用了吗？
答案 0 :(得分：1)
这是因为您使用的是不在德国IP范围内的VM。您有两种选择：
