使用 EWS 发送带有另一封邮件作为附件的新邮件

Question

我正在开发“outlook-web-addon”，它获取当前打开的消息并将其附加到新消息并将其发送到特定地址..所有这些都不允许用户交互（无撰写屏幕）

下面的代码一直传递到“创建附件”，这会产生错误： "此调用者或应用程序无法使用请求的 Web 方法"

function sendMessage() {
    //$("#y").load("x.html");
    //var mailBody = document.load("MailBody");
    //<object type="text/html" data="mailBody.html"></object>

    if (Office.context.mailbox.item.itemType !== Office.MailboxEnums.ItemType.Message) {
        return;
    }

    var parentId='';
    var mimeContent='';

    //Get current selected mail message Id
    var mailbox = Office.context.mailbox;
    var item = mailbox.item;
    var itemId = item.itemId;


    //1- Create Mime content from the current selected mail message

                } else {
                }
            });
    }
}

我在 Chrome 上尝试，它给了我这个错误： "此调用者或应用程序无法使用请求的 Web 方法"

另外，我想知道这是否适用于桌面 Outlook 应用程序？

Answer 1

根据https://docs.microsoft.com/en-us/outlook/add-ins/understanding-outlook-add-in-permissions#readwritemailbox-permission，MakeEWSRequestAsync 不允许附件操作。有一种 ReadOnly 方法可用于访问附件 https://docs.microsoft.com/en-us/outlook/add-ins/get-attachments-of-an-outlook-item（但我不相信这将允许您创建一个）。

我知道的唯一解决方法是，因为 CreateItem 是允许的，如果您要发送的消息首先在 Mime 中构建（附件 mime 编码），然后您可以从 MIMEContent 创建消息该内容应该可以工作。
