我一直在尝试编写一些基本代码来测试Azure KeyVault。目前（正如您从控制台日志中看到的），我可以进行身份验证，但 KeyVaultClient 只是失败并出现 [致命错误]：1：1：文件过早结束
与azure-java-sdk相比，微软似乎缺乏一些现实世界的例子，所以我承认我一直在努力解释JavaDocs！

要使用Azure KeyVault，您可以尝试使用Azure REST API来管理和操作Key Vault。请参阅Key Vault REST文档https://msdn.microsoft.com/en-us/library/azure/dn903630.aspx。
Key Vault管理有两套API，Key＆amp;秘密操作需要来自不同资源uri的不同访问令牌。
对于管理api，资源uri为https://management.core.windows.net/。
对于操作apis，资源uri为https://vault.azure.net。 （注意：请注意uri末尾没有符号/。）
以下是一个示例代码作为参考。
package aad.keyvault;

import java.net.MalformedURLException;

Azure Key Vault操作API需要使用命令set-policy设置的不同权限。例如Get information about a key（https://msdn.microsoft.com/en-us/library/azure/dn878080.aspx），需要授权才能通过使用Azure CLI cmd azure keyvault set-policy --vault-name <vault-name> --spn <service-principal-no.> --perms-to-keys '["get"]'向密钥添加权限get来获取密钥/获取权限。

您的代码适用于我，因此我怀疑您的凭据对象（您未提供）无效。特别是，请确保使用KeyVaultConfiguration实例。
这是我AzureKVCredentials的工作版本：
package com.example.cli;
import java.util.*;
import java.util.concurrent.*;
import com.microsoft.aad.adal4j.*;
import org.apache.http.*;
import org.apache.http.message.*;
import com.microsoft.azure.keyvault.*;
import com.microsoft.azure.keyvault.authentication.*;
import com.microsoft.windowsazure.*;
import com.microsoft.windowsazure.core.pipeline.filter.*;
public class AzureKVCredentials extends KeyVaultCredentials {
public static Configuration createConfiguration() {
return KeyVaultConfiguration.configure(null, new AzureKVCredentials());
}
@Override
public Header doAuthenticate(ServiceRequestContext request, Map<String, String> challenge) {
try {
String authorization = challenge.get("authorization");
String resource = challenge.get("resource");
AuthenticationResult authResult = getAccessToken(authorization, resource);
return new BasicHeader("Authorization", authResult.getAccessTokenType() + " " + authResult.getAccessToken());
} catch (Exception ex) {
throw new RuntimeException(ex);
}
}
private static AuthenticationResult getAccessToken(String authorization, String resource) throws Exception {
String clientId = "<app id of your Azure application>";
String clientKey = "<application key>";
AuthenticationResult result = null;
ExecutorService service = null;
try {
service = Executors.newFixedThreadPool(1);
AuthenticationContext context = new AuthenticationContext(authorization, false, service);
Future<AuthenticationResult> future = null;
ClientCredential credentials = new ClientCredential(clientId, clientKey);
future = context.acquireToken(resource, credentials, null);
result = future.get();
} finally {
service.shutdown();
}
if (result == null) {
throw new RuntimeException("authentication result was null");
}
return result;
}
}
此代码基于azure-sdk-for-java中的these sources。
