如何解决尝试从证书获取访问令牌？

我已经使用我的 Web API 应用程序配置了 Azure AD。 添加了 ClIEnt ID、Certificate、tenantID 所需的配置。 失败的身份验证上下文： 我使用的是 ADAl v5.2.9，authcontext 没有读取诸如 resourcEID、clIEntcredentials 之类的值

add-type -Path "..\ADAL\Microsoft.IDentitymodel.ClIEnts.ActiveDirectory.dll"

# Output Token and Response from AAD Graph API
$accesstoken = ".\Token.txt"
$output = ".\Output.Json"

# Application and Tenant Configuration
$clIEntID = "<AppIDGUID>"
$tenantID = "<TenantID>"
$resourcEID = "https://graph.windows.net" <using my own API>
$login = "https://login.microsoftonline.com"

# Create ClIEnt Credential Using Certificate
$certfile = "<PFXfilePath>"
$certfilepassword = "<Certpassword>"
$secret = New-Object -Typename System.Security.Cryptography.X509Certificates.X509Certificate -ArgumentList $certfile,$certfilepassword

# Get an Access Token with ADAL
$clIEntCredential = New-Object Microsoft.IDentitymodel.ClIEnts.ActiveDirectory.ClIEntCredential($clIEntID,$secret)
$authContext = New-Object Microsoft.IDentitymodel.ClIEnts.ActiveDirectory.AuthenticationContext("{0}/{1}" -f $login,$tenantID)
$authenticationResult = $authContext.Acquiretoken($resourcEID,$clIEntcredential)
($token = $authenticationResult.Accesstoken) | Out-file $accesstoken

# Call the AAD Graph API 
$headers = @{ 
    "Authorization" = ("Bearer {0}" -f $token);
    "Content-Type" = "application/Json";
}

# Output responsE into a JsON file
Invoke-RestMethod -Method Get -Uri ("{0}/{1}/users?API-version=1.6" -f $resourcEID,$tenantID)  -headers $headers -Outfile $output

低于错误

@H_298_5@methodInvocationException: C:\Users\final.ps1:22
line |
  22 |  $authenticationResult = $authContext.Acquiretoken($resourcEID,$clIEnt …
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Exception calling "Acquiretoken" with "2" argument(s): "sts_token_request_Failed: Token request to security token
     | service Failed.  check InnerException for more details"

解决方法

$authenticationResult = $authContext.AcquireToken($resourcEID,$clientcredential)
($token = $authenticationResult.AccessToken) | Out-File $accessToken

$authenticationTask = $authContext.AcquireTokenAsync($resourcEID,$clientcredential)
$authenticationTask.Wait()
$authenticationResult = $authenticationTask.Result
($token = $authenticationResult.AccessToken) | Out-File $accessToken
