操作回傳無效狀態代碼“BadRequest”-Microsoft.Azure.Management.ResourceGraph

每當var response行執行時，它都會拋出一個例外，指出

操作回傳了無效的狀態代碼“BadRequest”

我在 Azure Resource Graph Explorer 中執行的相同請求按預期作業。但是出于某種奇怪的原因，當我在運行 .net 6 框架的 .net 控制臺應用程式中執行此操作時，它告訴我這是一個錯誤的請求，而實際上它是正確的請求。但是，在顯示該錯誤后，它說Principal used: IsAuthenticated:True Type:User TenantId: xxxxx UserPrincipalName: xxxx

安裝的軟體包：

<PackageReference Include="Microsoft.Azure.Management.ResourceGraph" Version="2.1.0" />
    <PackageReference Include="Microsoft.Azure.Services.AppAuthentication" Version="1.6.2" />

程式.cs

using Microsoft.Azure.Management.ResourceGraph;
using Microsoft.Azure.Management.ResourceGraph.Models;
using Microsoft.Azure.Services.AppAuthentication;
using Microsoft.Rest;

AzureServiceTokenProvider azureServiceTokenProvider = new AzureServiceTokenProvider();
RunResourceGraphQuery(azureServiceTokenProvider).Wait();
if (azureServiceTokenProvider.PrincipalUsed != null)
{
    Console.WriteLine($"{Environment.NewLine}Principal used: {azureServiceTokenProvider.PrincipalUsed}");
}

Console.ReadLine();

static async Task RunResourceGraphQuery(AzureServiceTokenProvider azureServiceTokenProvider)
{
    Console.WriteLine($"{Environment.NewLine}{Environment.NewLine}Please enter the subscription Id");
    var subscriptionId = Console.ReadLine();
    List<string> subscriptions = new();
    subscriptions.Add(subscriptionId);

    try
    {
        var tokenCredentials = new TokenCredentials(await azureServiceTokenProvider.GetAccessTokenAsync("https://management.azure.com/").ConfigureAwait(false));
        var resourceGraphClient = new ResourceGraphClient(tokenCredentials);
        var userQueryRequest = new QueryRequest(subscriptions: subscriptions, query: "resources | project name, ['type'] | limit 5", null, null);

        var response = resourceGraphClient.Resources(userQueryRequest);
        Console.WriteLine(response);

    }
    catch (Exception exp)
    {
        Console.WriteLine($"Error message: {exp.Message}");
    }
}

uj5u.com熱心網友回復：

我已嘗試在我的環境中重新創建上述問題，并且遇到與您相同的問題。

使用 Console 應用程式創建了一個新專案，.net6并將您的代碼復制到我的本地 .

已安裝nuget packages：-

Microsoft.Azure.Management.ResourceGraph" 版本="2.1.0" Microsoft.Azure.Services.AppAuthentication" 版本="1.6.2"

這是我的 .csproj

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Azure.Management.ResourceGraph" Version="2.1.0" />
    <PackageReference Include="Microsoft.Azure.Services.AppAuthentication" Version="1.6.2" />
  </ItemGroup>

</Project>

當我嘗試使用您的代碼時，我得到Operation returned an invalid status code 'BadRequest'：

將查詢引數型別query: "resources | project name, ['type'] | limit 5" 更改為此 query: "Resources | project name, type | limit 5"

Program.cs:-

using Microsoft.Azure.Management.ResourceGraph;
using Microsoft.Azure.Management.ResourceGraph.Models;
using Microsoft.Azure.Services.AppAuthentication;
using Microsoft.Rest;

AzureServiceTokenProvider azureServiceTokenProvider = new AzureServiceTokenProvider();
RunResourceGraphQuery(azureServiceTokenProvider).Wait();
if (azureServiceTokenProvider.PrincipalUsed != null)
{
    Console.WriteLine($"{Environment.NewLine}Principal used: {azureServiceTokenProvider.PrincipalUsed}");
}

Console.ReadLine();

static async Task RunResourceGraphQuery(AzureServiceTokenProvider azureServiceTokenProvider)
{
    Console.WriteLine($"{Environment.NewLine}{Environment.NewLine}Please enter the subscription Id");
    var subscriptionId = Console.ReadLine();
    List<string> subscriptions = new();
    subscriptions.Add(subscriptionId);

    try
    {
        var tokenCredentials = new TokenCredentials(await azureServiceTokenProvider.GetAccessTokenAsync("https://management.azure.com/").ConfigureAwait(false));
        var resourceGraphClient = new ResourceGraphClient(tokenCredentials);
        var userQueryRequest = new QueryRequest(subscriptions: subscriptions, query: "Resources | project name, type | limit 5", null, null);

        var response = resourceGraphClient.Resources(userQueryRequest);
        Console.WriteLine(response);

    }
    catch (Exception exp)
    {
        Console.WriteLine($"Error message: {exp.Message}");
    }
}

它在我的最后作業正常：
