Outlook Web App(Exchange 2013内部部署)API 1.2如何访问电子邮件正文? [英] Outlook Web App (Exchange 2013 On-Premise) API 1.2 How to access Email Body?

问题描述

Office.context.mailbox.item.body给出空值

Office.context.mailbox.item.body.getAsync()仅适用于JavaScript API 1.3.

是否可以使用JavaScript API 1.1/1.2获取电子邮件正文?

Is there any way to fetch email body with JavaScript API 1.1/1.2?

推荐答案

可以.实际上，您将使用Exchange Web服务检索正文.

Yes you can. Actually, you will retrieve the body using Exchange Web Services.

此处有两种方法可以做到这一点:1)来自javascript(客户端应用)的SOAP请求或2)使用SDK的服务器端(例如.NET Exchange Web SDK)

As explained here there are two ways to do this: 1) SOAP request from javascript (client app) or 2) server side using an SDK such as the .NET Exchange Web SDK

对于解决方案1)，您的请求可能类似于以下js代码段(请注意，我在that.$q.defer();中使用了angular.js诺言，但这不是强制性的)

For solution 1), your request could look like the following js snippet (note that I have used an angular.js promise with that.$q.defer(); but this is not mandatory)

           function getSoapEnvelope(request) {
            // Wrap an Exchange Web Services request in a SOAP envelope.
            var result =
            '<?xml version="1.0" encoding="utf-8"?>' +
            '<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' +
            '               xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">' +
            '  <soap:Header>' +
            '     <t:RequestServerVersion Version="Exchange2013"/>' +
            '  </soap:Header>' +
            '  <soap:Body>' +
            request +
            '  </soap:Body>' +
            '</soap:Envelope>';

            return result;
           }



            var getBodyAsync = function () {
            var that =this;
            var deferred = that.$q.defer();

            function getHeadersRequest(id) {
                // Return a GetItem EWS operation request for the headers of the specified item.  
                var result =
             '    <GetItem xmlns="http://schemas.microsoft.com/exchange/services/2006/messages">' +
             '      <ItemShape>' +
             '        <t:BaseShape>IdOnly</t:BaseShape>' +
             '        <t:BodyType>HTML</t:BodyType>' +
             '        <t:AdditionalProperties>' +
             '            <t:FieldURI FieldURI="item:Body"/>' +
             '        </t:AdditionalProperties>' +
             '      </ItemShape>' +
             '      <ItemIds><t:ItemId Id="' + id + '"/></ItemIds>' +
             '    </GetItem>';
                return result;
            }
                // Create a local variable that contains the mailbox. 
            var mailbox = Office.context.mailbox;
            var request = getHeadersRequest(mailbox.item.itemId);
            var envelope = getSoapEnvelope(request);

            var callback = function (data) {
                var $data = $(data.value);
                var $body = $("t\\:Body", $data);
                deferred.resolve($body.html());
            }

            mailbox.makeEwsRequestAsync(envelope, callback);
            return deferred.promise;
        };

对于解决方案2)，使用.NET Exchange SDK

And for solution 2) with .NET Exchange SDK

            ExchangeService service = new ExchangeService();
            service.Credentials = new OAuthCredentials(token);
            service.Url = new Uri(ewsUrl);

            PropertyDefinition definition = ItemSchema.NormalizedBody;
            var propertySet = new PropertySet(definition, ItemSchema.Attachments,
                ItemSchema.HasAttachments);
            EmailMessage ewsEmail = EmailMessage.Bind(service, new ItemId(itemId), propertySet);


            return ewsEmail.NormalizedBody.Text;
