在特定日期之后使用php-ews获取电子邮件(Exchange Web Services) [英] Getting emails after a specific date with php-ews (Exchange Web Services)

问题描述

在我的PHP脚本中，我需要弄清楚如何检索在指定消息ID之后或在特定日期之后的所有电子邮件(这两种方法都可以，我只需要检索自上次我以来的新电子邮件)抓取收件箱).

In my PHP script, I need to figure out how to retrieve all emails that are either after a specified message ID or after a specific date (Either will work, I just need to retrieve emails that are new since the last time I scraped the inbox).

此收件箱每天会收到数千封电子邮件，而且30天内我无法删除任何电子邮件.对于最初的导入，我只是在收件箱的开头做一个偏移，但是很明显，一旦我们开始清除电子邮件，该操作就不会起作用.

This inbox is getting thousands of emails a day, and I can't delete any emails for 30 days. For the initial import I was just doing an offset from the beginning of the inbox, but obviously that won't work once we start cleaning out emails.

我认为我必须设置类" php-ews 中不存在必需的类让我做到这一点.我尝试自己添加它们，但是对EWS或SOAP的了解还不够.

I think I have to set the $Restriction property of the class "EWSType_FindItemType", but I don't think the necessary classes exist in php-ews for me to do this. I've tried to add them myself, but I don't understand enough about EWS or SOAP.

到目前为止，我唯一想到的是:

So far the only thing I've come up with is this:

$Request->Restriction = new EWSType_RestrictionType();
$Request->Restriction->IsGreaterThan = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURIOrConstant = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURIOrConstant->Constant = '2012-01-02T07:04:00Z';
$Request->Restriction->IsGreaterThan->FieldURI = new stdClass;
$Request->Restriction->IsGreaterThan->FieldURI->FieldURI = 'item:DateTimeReceived';

那行不通:(

这是我当前用于检索电子邮件的代码:

Here's the code I am currently using to retrieve email:

<?php
require( dirname( __FILE__ ) . '/ews/ExchangeWebServicesLoader.php' );

$ews = new ExchangeWebServices( EXCHANGE_HOSTNAME, EXCHANGE_USERNAME, EXCHANGE_PASSWORD, ExchangeWebServices::VERSION_2010_SP1 );

$Request = new EWSType_FindItemType();

$Request->ItemShape = new EWSType_ItemResponseShapeType();
$Request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::ALL_PROPERTIES;
$Request->ItemShape->BodyType = EWSType_BodyTypeResponseType::TEXT;
$Request->ItemShape->BodyTypeSpecified = true;

$Request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;

$Request->IndexedPageItemView = new EWSType_IndexedPageViewType();
$Request->IndexedPageItemView->MaxEntriesReturned = 25;
$Request->IndexedPageItemView->BasePoint = 'Beginning';
$Request->IndexedPageItemView->Offset = $offset;

$Request->ParentFolderIds = new EWSType_NonEmptyArrayOfBaseFolderIdsType();
$Request->ParentFolderIds->DistinguishedFolderId = new EWSType_DistinguishedFolderIdType();
$Request->ParentFolderIds->DistinguishedFolderId->Id = 'inbox';
$Request->ParentFolderIds->DistinguishedFolderId->Mailbox = new EWSType_EmailAddressType();
$Request->ParentFolderIds->DistinguishedFolderId->Mailbox->EmailAddress = '[e-mail]';

// sort order
$Request->SortOrder = new EWSType_NonEmptyArrayOfFieldOrdersType();
$Request->SortOrder->FieldOrder = array();
$order = new EWSType_FieldOrderType();
$order->FieldURI = new stdClass;
$order->FieldURI->FieldURI = 'item:DateTimeReceived';
$order->Order = 'Ascending';
$Request->SortOrder->FieldOrder[] = $order;

$response = $ews->FindItem($Request);
$items = $response->ResponseMessages->FindItemResponseMessage->RootFolder->Items->Message;

foreach ( $items as $item ) {
    // Do stuff
}

任何帮助都会非常感谢！

推荐答案

在EWS中，限制很棘手，这是事实.您可以看一下它们在 EWSWrapper 中使用的方式，这是示例如何创建AND限制以使它们之间的项目日期范围:

Restriction are tricky in EWS, true. You can take a look at haw they are used in EWSWrapper, here's example how to create AND restriction to get items in between date range:

//create AND restrction
$request->Restriction = new EWSType_RestrictionType();
$request->Restriction->And = new EWSType_AndType();

$request->Restriction->And->IsGreaterThanOrEqualTo = new EWSType_IsGreaterThanOrEqualToType();
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI = new EWSType_PathToExtendedFieldType;
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->DistinguishedPropertySetId = "Task";
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->PropertyId = "33029";
$request->Restriction->And->IsGreaterThanOrEqualTo->ExtendedFieldURI->PropertyType = "SystemTime";
$request->Restriction->And->IsGreaterThanOrEqualTo->FieldURIOrConstant->Constant->Value = date('c', $start);

$request->Restriction->And->IsLessThanOrEqualTo = new EWSType_IsLessThanOrEqualToType();
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI = new EWSType_PathToExtendedFieldType;
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->DistinguishedPropertySetId = "Task";
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->PropertyId = "33029";
$request->Restriction->And->IsLessThanOrEqualTo->ExtendedFieldURI->PropertyType = "SystemTime";
$request->Restriction->And->IsLessThanOrEqualTo->FieldURIOrConstant->Constant->Value = date('c', $end);

以及使用的类型:

class EWSType_RestrictionType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_SearchExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'SearchExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class RestrictionType

<?php

class EWSType_AndType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_MultipleOperandBooleanExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'MultipleOperandBooleanExpressionType',
        ),          
    ); // end $this->schema
} // end function __construct()
} // end class AndType
class EWSType_IsLessThanOrEqualToType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_TwoOperandExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'TwoOperandExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class IsLessThanOrEqualToType


class EWSType_IsGreaterThanOrEqualToType extends EWSType {
/**
 * SearchExpression property
 * 
 * @var EWSType_TwoOperandExpressionType
 */
public $SearchExpression;

/**
 * Constructor
 */
public function __construct() {
    $this->schema = array(
        array(
            'name' => 'SearchExpression',
            'required' => false,
            'type' => 'TwoOperandExpressionType',
        ),
    ); // end $this->schema
} // end function __construct()
} // end class IsGreaterThanOrEqualToType
