我面临着一些挑战，而与MS图形API的工作，特别是与预订一。错误如下
GET https://graph.microsoft.com/v1.0/solutions/bookingBusinesses导致401 Unauthorized响应：{“error”：{“code”：“InvalidAuthenticationToken”，“message”：“访问令牌验证失败。"，“innerError”：{“date”：“2023-09-22T06：36：11”，“request-id”：“5d73f58d-9297-4ca8-bfe6-bafee1ebc54b”，“client-request-id”：“5d73f58d-9297-4ca8-bfe6-bafee1ebc54b”}
到目前为止我做的代码是

public function listAppoinment($userPrincipalName){
    $this->graph->setAccessToken($this->grant_type_password());
    $event = $this->graph->createRequest("GET", "/solutions/bookingBusinesses")
        ->execute();

}

private function grant_type_password(){
    $configuration = [
        'form_params' => [
            'client_id' => $this->clientId,
            'client_secret' => $this->clientSecret,
            'grant_type' => 'password',
            'scope' => "api://$this->clientId/Userlogin",
            'username' => 'myMailid',
            'password' =>'password'
        ],
        'http_errors' => false,
        'curl' => [
            CURLOPT_FAILONERROR => false
        ],
        'headers' => [
            'Content-Type' => 'application/x-www-form-urlencoded'
        ]
    ];
    $guzzle = new Client();
    $url = 'https://login.microsoftonline.com/' . $this->tenentId . '/oauth2/v2.0/token';
    $response = $guzzle->post($url, $configuration);
    $responseBody = json_decode($response->getBody()->getContents(), false, 512, JSON_THROW_ON_ERROR);

    if ($response->getStatusCode() !== 200) {
        $error = $responseBody->error ?? $response->getStatusCode();
        trigger_error($responseBody->error_description ?? $error, E_USER_ERROR);
    }

    return $responseBody->access_token;
}
