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那样），我可以进行身份​​验证，但KeyVaultClient只是失败并出现[Fatal Error] :1:1: Premature end of file。

微软似乎缺乏与 azure-java-sdk 相关的真实示例，所以我承认我一直在努力解释 JavaDocs ！

要使用 Azure KeyVault，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。

有两组 API 用于 Key Vault 管理和 Keys & Secrets 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 是https://management.core.windows.net/.

对于操作 api，资源 uri 是https://vault.azure.net. （注意：请注意uri 末尾没有符号/。 ）

这是一个示例代码作为参考。

package aad.keyvault;

import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.concurrent.ExecutionException;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

import javax.naming.ServiceUnavailableException;
import javax.net.ssl.HttpsURLConnection;

import org.apache.commons.io.IOUtils;

import com.microsoft.aad.adal4j.AuthenticationContext;
import com.microsoft.aad.adal4j.AuthenticationResult;
import com.microsoft.aad.adal4j.ClientCredential;

public class RestAPISample {

    private static final String subscriptionId = "<subscription_id>";
    private static final String resourceGroupName = "<resource_group_name>";
    private static final String vaultName = "<vault_name>";
    private static final String apiVersion = "2015-06-01";
    private static final String getKeyVaultInfoUri = String.format(
            "https://management.azure.com/subscriptions/%s/resourceGroups/%s/providers/Microsoft.KeyVault/vaults/%s?api-version=%s",
            subscriptionId, resourceGroupName, vaultName, apiVersion);

    private static final String tenantId = "<tenant_id>";
    private static final String authority = String.format("https://login.windows.net/%s", tenantId);
    private static final String clientId = "<client_id>";
    private static final String clientSecret = "<client_secret_key>";
    private static final String keyName = "<keyvault_key>";
    private static final String getInfoFromAKeyUri = String.format("https://%s.vault.azure.net/keys/%s?api-version=%s",
            vaultName, keyName, apiVersion);

    public static String getAccessToken(String resource)
            throws MalformedURLException, InterruptedException, ExecutionException, ServiceUnavailableException {
        AuthenticationContext context = null;
        AuthenticationResult result = null;
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            context = new AuthenticationContext(authority, true, service);
            ClientCredential credential = new ClientCredential(clientId, clientSecret);
            Future<AuthenticationResult> future = context.acquireToken(resource, credential, null);
            result = future.get();
        } finally {
            service.shutdown();
        }
        String accessToken = null;
        if (result == null) {
            throw new ServiceUnavailableException("authentication result was null");
        } else {
            accessToken = result.getAccessToken();
            System.out.println("Access Token: " + accessToken);
        }
        return accessToken;
    }

    public static void getKeyVaultInfo() throws MalformedURLException, IOException, ServiceUnavailableException,
            InterruptedException, ExecutionException {
        System.out.println(getKeyVaultInfoUri);
        HttpsURLConnection conn = (HttpsURLConnection) new URL(getKeyVaultInfoUri).openConnection();
        conn.setRequestProperty("Authorization", "Bearer " + getAccessToken("https://management.core.windows.net/"));
        conn.addRequestProperty("Content-Type", "application/json");
        String resp = IOUtils.toString(conn.getInputStream());
        System.out.println(resp);
    }

    public static void getKeyInfo() throws MalformedURLException, IOException, ServiceUnavailableException, InterruptedException, ExecutionException {
        System.out.println(getInfoFromAKeyUri);
        HttpsURLConnection conn = (HttpsURLConnection) new URL(getInfoFromAKeyUri).openConnection();
        conn.setRequestProperty("Authorization", "Bearer " + getAccessToken("https://vault.azure.net"));
        conn.addRequestProperty("Content-Type", "application/json");
        String resp = IOUtils.toString(conn.getInputStream());
        System.out.println(resp);
    }

    public static void main(String[] args)
            throws InterruptedException, ExecutionException, ServiceUnavailableException, IOException {
        getKeyVaultInfo();
        getKeyInfo();
    }

}

Azure Key Vault 操作 API 需要使用 command 设置不同的权限set-policy。例如Get information about a key（https://msdn.microsoft.com/en-us/library/azure/dn878080.aspx），它需要授权需要密钥/通过使用 Azure CLI cmd 获取权限来为密钥azure keyvault set-policy --vault-name <vault-name> --spn <service-principal-no.> --perms-to-keys '["get"]'添加权限get。

您的代码对我有用，所以我怀疑您的凭据对象（您没有提供）无效。特别是，请确保使用KeyVaultConfiguration实例。

这是我的工作版本AzureKVCredentials：

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;
    }

}

此代码基于来自 azure-sdk-for-java 的这些源代码。
