网页插件展望

Question

我正在使用 EWS 和 JavaScript 为 Outlook 开发一个新的网络插件。范围是选择当前电子邮件并将其作为附件添加到新电子邮件中。按照此处的说明进行操作：https://msdn.microsoft.com/en-us/library/office/dn726694(v=exchg.150).aspx#bk_createattachews -> 我创建了一些函数来执行 MSDN 文档中解释的那些步骤。问题是我没有得到任何错误或可以告诉我我做错了什么的东西。这是我的代码：

 function soapToForwardItemCallback(asyncResult) {
        var parser;
        var xmlDoc;

        if (asyncResult.error != null) {
            app.showNotification("EWS Status", asyncResult.error.message);
        }
        else {
            var response = asyncResult.value;
            if (window.DOMParser) {
                parser = new DOMParser();
                xmlDoc = parser.parseFromString(response, "text/xml");
            }
            else // Older Versions of Internet Explorer
            {
                xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
                xmlDoc.async = false;
                xmlDoc.loadXML(response);
            }

            // Get the required response, and if it's NoError then all has succeeded, so tell the user.
            // Otherwise, tell them what the problem was. (E.G. Recipient email addresses might have been
            // entered incorrectly --- try it and see for yourself what happens!!)
            var result = xmlDoc.getElementsByTagName("m:ResponseCode")[0].textContent;
            if (result == "NoError") {
                app.showNotification("EWS Status", "Success!");
            }
            else {
                app.showNotification("EWS Status", "The following error code was recieved: " + result);
            }
        }

单击按钮时调用的第一个函数是 getCurrentEmail()。我不确定我是否可以那样进行 SOAP 调用。任何帮助将不胜感激！如果您需要更多信息，请告诉我。谢谢！

Answer 1

I am not sure if I can do the SOAP calls like that.

以下资源描述了 EWS operations that add-ins support。 "m:CreateAttachment" 不是其中之一；也许你应该从那里开始。

编辑：

我不明白你怎么没有收到任何错误。你在调试吗？你能打断点吗？好吧，这一切都很奇怪。现在让我告诉你我做了什么以及我注意到你的代码有什么问题......

我创建了简单项目并添加了您的代码。我调用了 "getCurrentEmail()" 函数并仅使用该函数。我没有验证任何其他功能，因为我相信你应该自己做。
Javascript 错误：如果你使用 "strict" JS 模式（你应该！）函数有 "item_id" 变量，它没有定义为 "var".您应该使用 "var" 关键字将其设为本地。接下来，当您调用 "mailbox.makeEwsRequestAsync" 时，"mailbox" 变量也是未定义的。你应该称它为 "Office.context.mailbox.makeEwsRequestAsync"。
EWS 请求的格式根本不正确。我不知道，也许你玩过它，但是你提供的资源中的示例 EWS XML 与你通过插入消息 ID 创建的不同。当我修复 JS 错误（查看上面的第 2 点）并发送 EWS 请求时，它返回开始 "Error" 并正确描述请求格式错误。我已更改请求以匹配示例中提供的请求，它 returns "success" 和您请求的信息，如主题和 MIME 内容。

我将仅针对您要求的功能分享我的代码，其余的请自行尝试。给你...
