Getting Unathorized when trying to get a secret from Azure key Vault

Question

I\'m using Microsoft.Azure.keyVault trying to get a secret from a key vault in Azure.

I\'ve registered an application as both Native and Web API.

Answer 1

I test it with the following code, it works correctly on my side. The resourceUri is https://vault.azure.net

 static string appId = "application Id";
 static string tenantId = "tenant id";
 static string uri = "http://localhost:13526"; //redirect uri
 static void Main(string[] args)
 {
    var kv = new KeyVaultClient(GetAccessToken);
    var scret = kv.GetSecretAsync("https://xxxx.vault.azure.net", "xxxx").GetAwaiter().GetResult();
 }

 public static async Task<string> GetAccessToken(string azureTenantId,string clientId,string redirectUri)
 {
       var context = new AuthenticationContext("https://login.windows.net/" + tenantId);
       var tokenResult = await context.AcquireTokenAsync("https://vault.azure.net", appId, new Uri(uri), new PlatformParameters(PromptBehavior.SelectAccount));
       return tokenResult.AccessToken;
  }

The following is my detail steps.

1.Registry an native application

2.Add KeyVault Permission

3.Add the above code and test it on my side.
