在 Php-Ews 中创建联系人时避免重复的项目

Question

我正在使用 https://github.com/Garethp/php-ews/库来访问我在Exchange服务器上的公共联系人文件夹。

这就是我创建联系人的方式。

$api = API::withUsernameAndPassword($server, $user, $pass);
$folder = $api->getFolderByDisplayName('Public', EnumerationDistinguishedFolderIdNameType::PUBLICFOLDERSROOT);
$contattiTotali = $api->getFolderByDisplayName('Contacts', $folder->getFolderId());
$id=$contattiTotali->getFolderId()->getId();
$api->setFolderId($contattiTotali->getFolderId());
$api->createContacts(array(
'GivenName' => 'Homer',
'Surname' => 'Simpson',
'EmailAddresses' => array(
'Entry' => array('Key' => EnumerationEmailAddressKeyType::EMAIL_ADDRESS_1, '_value' => '[e-mail]')
),
//Creating multiple entries
'PhoneNumbers' => array(
'Entry' => array(
array('Key' => EnumerationPhoneNumberKeyType::HOME_PHONE, '_value' => '000'),
array('Key' => EnumerationPhoneNumberKeyType::BUSINESS_PHONE, '_value' => '111'),
)
),
'PhysicalAddresses' => array(
'Entry' => array(
'Key' => EnumerationPhysicalAddressKeyType::HOME,
'street' => '123 Street',
'city' => '123 City',
'state' => '123 State',
'countryOrRegion' => '123 Country',
'postalCode' => '12345',
)
),
));

实际上，代码工作正常，但是如果我执行几次，它会复制联系人。

在创建新联系人之前，有没有办法检查联系人(电子邮件地址足够好(是否已存在？

Answer 1

判断特定电子邮件地址的联系人是否已经存在的最简单方法是使用 ResolveName 操作，例如

$request = new EWSType_ResolveNamesType();
$request->UnresolvedEntry = "[e-mail]";
$request->ReturnFullContactData = true;
$return = $ews->ResolveNames($request);
if ($return->ResponseMessages->ResolveNamesResponseMessage->ResponseCode == "NoError") {
return $return->ResponseMessages->ResolveNamesResponseMessage->ResolutionSet->Resolution->Mailbox->EmailAddress;
}
