使用@azure/identity访问密钥保管库并获取错误'；请求缺少承载或PoP令牌错误401'；

我试图从Azure的keyvault中检索一些机密，但我似乎无法使用@Azure/identity module进行身份验证

版本：

"@azure/identity": "^1.0.0-preview.6",
"@azure/keyvault-secrets": "^4.0.0-preview.9",

我有一个azure functions应用程序，我已经在生产和本地使用

local.settings.json

配置了该应用程序，并为以下内容填写了正确的值：

{
    "IsEncrypted": false,
    "Values": {
        "AZURE_CLIENT_ID": "REDACTED",
        "AZURE_CLIENT_SECRET": "REDACTED",
        "AZIRE_TENANT_ID": "REDACTED"
    },
    "ConnectionStrings": {}
}

• 通过Azure Active Directory注册的应用=>应用注册
• 禁用登录
• 已创建应用程序机密

然后，我将该应用程序添加到keyvault中，其角色为“阅读器”，使其能够“获取”机密，但除此之外，没有其他功能，甚至没有列表：

现在，当我试图找回这些秘密时：

import { KeyVaultSecret, SecretClient } from '@azure/keyvault-secrets';
import { EnvironmentCredential } from '@azure/identity';

export const GetSecret = async (key: string): Promise<string> => {
    try {
        const credential: EnvironmentCredential = new EnvironmentCredential();

        console.log('CREDENTIAL: ', credential);
        console.log('CLIENT SECRET', process.env.AZURE_CLIENT_SECRET);
        console.log('CLIENT ID', process.env.AZURE_CLIENT_ID);

        const url = 'https://tlabs-vault.vault.azure.net';
        const client = new SecretClient(url, credential);
        let secret: KeyVaultSecret = await client.getSecret(key);
        return secret.value;
    } catch (err) {
        console.error('Error getting secret from Azure Vault', err);
    }
};

以及引发错误的完整请求：

请关注这个博客，了解如何使用它

主要步骤是

为功能应用启用系统授权的托管身份

和

为功能应用添加密钥库访问策略

在这些操作之后，不要忘记在函数应用程序配置中使用

@Microsoft.KeyVault（SecretUri={用户名密码的复制标识符}）

添加密钥库密码引用。如果设置正确，配置后将显示下图

下面是我的测试结果，我使用

os.environ[name]

来获取秘密

有关此问题的任何更新，您现在可以使用key vault吗？@GeorgeChen嗨George，我已经制作了一个关于此问题的github线程，其中链接了我在该问题上制作的两个线程。问题是租户ID属性丢失（拼写错误），并且只有在我使用“ClientSecretCredential”方法时，它才提供有意义的错误消息。我确实需要在RBAC之上添加一个访问策略，但是它提供了一个有意义的错误消息，所以很容易识别。
