如何从php中的microsoft图形sdk数据响应中获取contentBytes值

Question

我的代码是

$expand="microsoft.graph.itemattachment/item";
            $requestUrl = '/me/messages/'.$message->getId().'/attachments/?$expand=  '.$expand;
            $docDatas = $userClient->createCollectionRequest('GET', $requestUrl)
                                    ->setReturnType(Model\Message::class)
                                    ->setPageSize(1)
                                      ->getPage();

并希望获得outlook电子邮件附件。

您可以用一个Message类扩展CustomMessage，如果要广泛使用它，就可以为该属性提供一个特定的getter。我的假设是您使用msgraph sdk-php库。

其他更简单的解决办法是：

$expand="microsoft.graph.itemattachment/item";
$requestUrl = '/me/messages/'.$message->getId().'/attachments/?$expand=  '.$expand;
$docDatas = $userClient->createCollectionRequest('GET', $requestUrl)
                       ->setReturnType(Model\Message::class)
                       ->setPageSize(1)
                       ->getPage();

$properties = $docDatas->getProperties();
$contentBytes = $properties["contentBytes"];

Message扩展了OutlookMessage，后者扩展了Microsoft\Graph\Model\Entity。您可以在该类中找到getProperties方法。
