无法向Office JS加载项添加附件

Question

我创建了一个附加电子邮件的EWS请求，但是我收到了空值，但状态为“成功”。顺便说一句。

我首先创建了一个makeEwsRequestAsync请求，用于将电子邮件保存到草稿，它已经可以工作但是当我尝试使用此请求添加附件时它没有添加。任何建议或帮助请

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
function createAttachment() {

    var request =
        '<?xml version="1.0" encoding="utf-8"?>' +
        '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' +
        'xmlns:xsd="http://www.w3.org/2001/XMLSchema"' +
        'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' +
        'xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">' +
        '  <soap:Body>' +
        '    <CreateAttachment xmlns="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">' +
        '      <ParentItemId Id="'+itemID+'" />' +
        '      <Attachments>' +
        '        <t:ItemAttachment>' +
        '          <t:Name>Please</t:Name>' +
        '           <t:Message>' +
        '               <t:ItemClass>IPM>Note</t:ItemClass>' +
        '               <t:Subject>test</t:Subject>' +
        '               <t:Body BodyType="Text">my test</t:Body>' +
        '           </t:Message>' +
        '        </t:ItemAttachment>' +
        '      </Attachments>' +
        '    </CreateAttachment>' +
        '  </soap:Body>' +
        '</soap:Envelope>';
    return request;
}

</script>

这是我创建附件EWS请求

Answer 1

看起来像我的坏XML，例如

'<t:ItemClass>IPM>Note</t:ItemClass>' +

会在服务器上产生验证错误（您应该在服务器的EWS响应中看到，例如您的请求应该是

'<t:ItemClass>IPM.Note</t:ItemClass>'

Answer 2

如果要从撰写模式处理电子邮件，可以参考Microsoft团队的此文档。我相信它更加简单和全面。

-https://docs.microsoft.com/en-us/outlook/add-ins/add-and-remove-attachments-to-an-item-in-a-compose-form

否则，如果您想从读取模式操纵电子邮件。可以有两种选择。

一种是使用Rest API。但是，提出此请求需要满足一些要求。我在桌面上不起作用，但在Web上工作，但如果你想尝试一下，你可以参考这个链接：https://docs.microsoft.com/en-us/outlook/add-ins/use-rest-api

遇到最低要求问题。我发现了一种使用Exchange Web服务请求（EWS）使其工作的方法。它主要使用XML文件发送请求以交换Web服务并返回响应。

但是，我发现我需要获得该电子邮件的MimeContent才能添加到我的CreateItem xml请求中。请查看此链接以获取更多信息。 https://docs.microsoft.com/en-us/exchange/client-developer/web-service-reference/getitem-operation-email-message

然后，我使用其MimeContent将现有项添加到新电子邮件中。您可以使用以下链接查看：https://docs.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-add-attachments-by-using-ews-in-exchange
