在网上搜索了几个小时后，你是我最后的希望：
我必须建立一个系统来读取从Microsoft Exchange Server发送和接收的邮件。我找到了以下脚本：Exchange Web Services for PHP（Heartspring）https://github.com/Heartspring/Exchange-Web-Services-for-PHP
现有的get_messages（）函数返回文件夹的所有消息，例如"inbox"。到目前为止一切都很清楚。当我想从"已发送"文件夹中获取所有邮件时，我的问题就开始了——我试过很多单词，从"发送"到"已发送邮件"；没有任何结果（邮箱不可用）
我的想法是获得文件夹"根"的所有子文件夹，并写道：
include "init.php";
$ec = new ExchangeClient();
$ec->init("bambullis@123.de", "", NULL, "https://amxprd3610.outlook.com/EWS/Services.wsdl");
$folders = $ec->get_subfolders("root");
foreach($folders as $folder) {
print_r($folder);
}
这就是我得到的：
stdClass Object
(
[FolderId] => stdClass Object
(
[Id] => AAAeAGJhbWJ1bGxpc0BzdHVrZSbi5kZQAuAAAAAABw352p5E4yS5voYF9ELBmiAQBXYPdO6NZAQ6T9C3xviT7xAAAAC1iXAAA=
[ChangeKey] => AQAAABYAAABXYPdO6NZAQ6T9C3xviAALNCey
)
[DisplayName] => Oberste Ebene des Informationsspeichers
[TotalCount] => 0
[ChildFolderCount] => 16
[UnreadCount] => 0
)
（我知道FolderId->Id是base64编码的，出于安全原因，我修改了上面的字符串；o）
现在我尝试列出这个目录的子文件夹（我添加了一个邮箱，看看"ChildFolderCount"值是否会更改）：
...
print_r($folder);
print_r($ec->get_subfolders($folder->FolderId->Id));
...
这是我得到的错误：请求架构验证失败："Id"属性是无效的
我做错了什么？如何递归地从"根"中获取所有子文件夹？感谢这个可爱的家伙，他可以帮助我！
EWS-PHP get_subfolders方法默认使用TraversalType"Shallow"，因此它只搜索已识别的文件夹，并只返回尚未删除项目的文件夹ID
要在已识别父文件夹的所有子文件夹中搜索并仅返回尚未删除项目的文件夹ID，应使用"Deep"TraversalType
例如：
<?php
include "init.php";
class myExchangeClient extends ExchangeClient {
public function get_subfolders_deep($ParentFolderId = "inbox", $Distinguished = TRUE) {
$this->setup();
$FolderItem = new stdClass();
$FolderItem->FolderShape = new stdClass();
$FolderItem->ParentFolderIds = new stdClass();
$FolderItem->FolderShape->BaseShape = "Default";
/*
** See http://msdn.microsoft.com/en-us/library/exchange/exchangewebservices.folderquerytraversaltype(v=exchg.140).aspx
** Deep Traversal: Searches in all subfolders of the identified parent folder and returns only the folder IDs for items that
** have not been deleted.
*/
$FolderItem->Traversal = "Deep";
if ($Distinguished) {
$FolderItem->ParentFolderIds->DistinguishedFolderId = new stdClass();
$FolderItem->ParentFolderIds->DistinguishedFolderId->Id = $ParentFolderId;
} else {
$FolderItem->ParentFolderIds->FolderId = new stdClass();
$FolderItem->ParentFolderIds->FolderId->Id = $ParentFolderId;
}
$response = $this->client->FindFolder($FolderItem);
if ($response->ResponseMessages->FindFolderResponseMessage->ResponseCode == "NoError") {
$folders = array();
if (!is_array($response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder)) {
$folders[] = $response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder;
} else {
$folders = $response->ResponseMessages->FindFolderResponseMessage->RootFolder->Folders->Folder;
}
return $folders;
} else {
$this->lastError = $response->ResponseMessages->FindFolderResponseMessage->ResponseCode;
}
}
}
$ec = new myExchangeClient();
$ec->init("bambullis@123.de", "", NULL, "https://amxprd3610.outlook.com/EWS/Services.wsdl");
$folders = $ec->get_subfolders_deep("root");
echo "<pre>".print_r($folders,true)."</pre>'n";
?>
无论如何，查看ExchangeClient类源代码，发送项目的FolderID应该是"sentems"。
