【问题描述】：

以下代码适用于单个附件，但适用于多个文件。

<?php
$msgRequest->MessageDisposition = 'SaveOnly';

$msgResponse = $ews->CreateItem($msgRequest);
$msgResponseItems = $msgResponse->ResponseMessages->CreateItemResponseMessage->Items;

// Create attachment(s)
$attachments = array();
$i = 0;
foreach ($message_details['attachment'] as $attachment) {
    $attachments[$i] = new EWSType_FileAttachmentType();
    $attachments[$i]->Content = file_get_contents($attachment['path'] . '/' . $attachment['file']);
    $attachments[$i]->Name = $attachment['file'];
    $i++;
}
//
// Attach files to message
$attRequest = new EWSType_CreateAttachmentType();
$attRequest->ParentItemId = $msgResponseItems->Message->ItemId;
$attRequest->Attachments = new EWSType_NonEmptyArrayOfAttachmentsType();
$attRequest->Attachments->FileAttachment = $attachments;

$attResponse = $ews->CreateAttachment($attRequest);
$attResponseId = $attResponse->ResponseMessages->CreateAttachmentResponseMessage->Attachments->FileAttachment->AttachmentId;

// Save message id from create attachment response
$msgItemId = new EWSType_ItemIdType();
$msgItemId->ChangeKey = $attResponseId->RootItemChangeKey;
$msgItemId->Id = $attResponseId->RootItemId;

// Send and save message
$msgSendRequest = new EWSType_SendItemType();
$msgSendRequest->ItemIds = new EWSType_NonEmptyArrayOfBaseItemIdsType();
$msgSendRequest->ItemIds->ItemId = $msgItemId;
$msgSendRequest->SaveItemToFolder = true;
$msgSendResponse = $ews->SendItem($msgSendRequest);
$response = $msgSendResponse->ResponseMessages->SendItemResponseMessage;
?>

$ews->SendItem() 返回此错误：

未捕获的 SoapFault 异常：[a:ErrorSchemaValidation] 请求架构验证失败：缺少必需的属性“Id”。

我错过了什么？

【解决方案1】：

在这里找到答案：

如果只有一个附件，Exchange 基本上不会使用数组，因此需要进行额外检查以确定从何处获取 ID。

if(!is_array($attResponse->ResponseMessages->CreateAttachmentResponseMessage))
    $attResponseId = $attResponse->ResponseMessages->CreateAttachmentResponseMessage->Attachments->FileAttachment->AttachmentId;
else {
    $attResponseId = $attResponse->ResponseMessages->CreateAttachmentResponseMessage[0]->Attachments->FileAttachment->AttachmentId;
}

Exchange 对收件人使用相同的结构。我觉得这不一致，但我相信这背后是有原因的。

我希望有人能从提出这个问题中受益。
