获取 OAUth 2.0 令牌的 Azure 函数不起作用

Question

我正在学习本教程：

Access Google Analytics with Azure Data Factory

我正在努力解决的是 Azure 功能。

这是 .net / C# 代码：

using Azure.Identity;
using Azure.Security.KeyVault.Secrets;
using Google.Apis.Auth.OAuth2;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using System;
using System.Threading.Tasks;
 
namespace GoogleAnalytics
{
    public class GetOAuthToken
    {
        [FunctionName("GetOAuthToken")]
        public async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", Route = null)] HttpRequest req)
        {
            var kvClient = new SecretClient(new Uri(Environment.GetEnvironmentVariable("KEY_VAULT_URL")), new ManagedIdentityCredential());
            string keyJson = kvClient.GetSecret("KEY_VAULT_URL").Value.Value;
 
            var cred = GoogleCredential.FromJson(keyJson).CreateScoped(new string[] { "https://www.googleapis.com/auth/analytics.readonly" });
            var token = await cred.UnderlyingCredential.GetAccessTokenForRequestAsync();
 
            return new OkObjectResult("{\"token\":\"" + token + "\"}");
        }
    }
}

我在 Azure 门户中使用以下参数创建了一个新的 Azure Function App：

发布：代码
运行时堆栈：.NET
版本：3.1
地区：德国

我点击代码 + 测试并将代码粘贴到窗口中。

如果我运行代码，我会收到以下错误：

我是否需要在我的 Azure 租户中安装任何包，还是需要事先做任何其他事情？

函数从哪里知道秘密以及使用哪个密钥库？我需要替换此代码中的占位符吗？教程在这方面不是很具体。

Answer 1

从您分享的教程来看，该过程看起来不错，查看您的堆栈跟踪，您导入的所有模块都丢失了。

确保您登录Visual Studio code 并导入所有包并添加 Azure Core 服务扩展、安装 Azure 功能扩展。

从本地测试函数并将其部署到您的函数应用。部署后，将所有本地设置添加到 Azure 函数应用门户的配置下的应用程序设置。
