Question

我使用以下函数在Azure AD上创建架构扩展，但我最终得到以下错误：

{
  "code":"InternalServerError",
   "message":"Object reference not set to an instance of an object."
}

以下是我的功能：

public function createExtension($id, $description, $targetTypes) {
    $token = $this - > getToken();
    // $graph = new Graph();
    // $graph->setAccessToken($token);

    $headers = [
        'Authorization: Bearer '.$token,
        'Content-Type: application/json'
    ];

    $data = json_encode([
        'id' => $id, 
        'description' => $description, 
        'targetTypes' => ["User"], 
        'status' => 'Available'
    ]);

    $ch = curl_init('https://graph.microsoft.com/beta/schemaExtensions');
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $arr = json_decode(curl_exec($ch), true);
    $logger = $this - > container - > get('monolog.logger.azure');
    $logger - > info('Values', ['ch' => $arr]);
    return $arr - > id;
}

您的代码的主要*问题是您缺少必需的properties字段。

正如Microsoft Graph doc on creating schema extensions中所述，您必须在创建新id时提供description，targetTypes，properties和schemaExtension。（owner属性是可选的。）

以下代码应该有效。（请注意，我已经切换到使用v1.0端点，因为它已经没有测试版了。）

$token = $this->getToken(); // Assume this does what the name implies

$headers = [
    'Authorization: Bearer ' . $token,
    'Content-Type: application/json'
];

$data = json_encode([
    'id' => 'size', 
    'description' => 'Height and shoe size', 
    'targetTypes' => ['User'],
    'properties' => [
        [
            'id' => 'shoeSize',
            'type' => 'Integer',
        ],
        [
            'id' => 'height',
            'type' => 'Integer',
        ],
        [
            'id' => 'tShirtSize',
            'type' => 'String',
        ],
    ]
]);

$ch = curl_init('https://graph.microsoft.com/v1.0/schemaExtensions');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$schemaExtension = json_decode(curl_exec($ch));
return $schemaExtension->id;

如果您想使用Microsoft Graph SDK for PHP，代码看起来非常相似：

use Microsoft\Graph\Graph;
use Microsoft\Graph\Model;

$token = $this->getToken(); // Assume this does what the name implies

$graph = new Graph();
$graph->setAccessToken($token);

$newSchemaExtension = new Model\SchemaExtension([
    'id' => 'sizes', 
    'description' => 'Height, shoe and shirt size', 
    'targetTypes' => ['User'],
    'properties' => [
        [
            'name' => 'shoeSize',
            'type' => 'Integer',
        ],
        [
            'name' => 'height',
            'type' => 'Integer',
        ],
        [
            'name' => 'shirtSize',
            'type' => 'String',
        ],
    ]
]);

$schemaExtension = $graph->createRequest('POST', '/schemaExtensions')
                        ->attachBody($newSchemaExtension)
                        ->setReturnType(Model\SchemaExtension::class)
                        ->execute();
return $schemaExtension->getId();

*缺少properties属性是主要问题，但您还有其他一些问题：

您尝试使用id引用$arr->id属性，但json_decode($string, true)会返回关联数组，因此您将使用$arr['id']代替。
您正在尝试在创建期间设置架构扩展的status，这也会导致错误（尽管它是不同的错误）。首次创建架构扩展时，请省略status字段，并在准备好后再更新。
