目前是否有Office 365 Rest API来检索电子邮件的纯文本部分？
从API文档中可以看出，'Body'对象包含'ContentType'字段，该字段可以是Text或HTML。 https://msdn.microsoft.com/office/office365/APi/complex-types-for-mail-contacts-calendar#ItemBody
但是，每当检索到多部分（HTML +纯文本）消息时，API只返回HTML部分，如下所示：
{
"@odata.context": "",
"@odata.id": "",
"Id": "",
"Subject": "Test message",
"BodyPreview": "This is the body",
"Body": {
"ContentType": "HTML",
"Content": "<html>\r\n<head>\r\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\">\r\n</head>\r\n<body style=\"word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; color: rgb(0, 0, 0); font-size: 14px; font-family: Calibri, sans-serif;\">\r\n<div>This is the body</div>\r\n</body>\r\n</html>\r\n"
},
"UniqueBody": {
"ContentType": "HTML",
"Content": "<html><body><div>\r\n<div><font face=\"Calibri,sans-serif\" size=\"2\" color=\"black\"><span style=\"font-size:14px;\">\r\n<div>This is the body</div>\r\n</span></font></div>\r\n</div>\r\n</body></html>"
},
"HasAttachments": false,
"Sender": {
"EmailAddress": {
"Address": "",
"Name": "Nick Maher"
}
},
"DateTimeReceived": "2015-02-10T14:39:22Z",
"DateTimeSent": "2015-02-10T14:39:21Z"
}
无论如何得到纯文本部分。可能是OData查询？
非常感谢，尼克
不，这是不可能的。我可以向开发人员提供此反馈。你能给我一些你需要这种能力的背景吗？不是我在质疑，有一些背景是有帮助的。 :)
只是想提供更新 - 您现在可以使用Microsoft Graph REST API来获取以文本格式返回的消息。
请注意，此功能目前仅在预览中。一般情况下，我们建议仅在非生产应用中使用预览功能，因为它们可能会更改，恕不另行通知。
我在下面列举了一个例子。 Microsoft Graph - Get和List消息的相关文档将在第二天更新。
此示例显示如何使用Prefer：outlook.body-content-type =“text”标头以文本格式获取指定消息的正文和uniqueBody。
Prefer: outlook.body-content-type="text"
GET https://graph.microsoft.com/beta/me/messages('AAMkAGI1AAAoZCfHAAA=')?$select=subject,body,bodyPreview,uniqueBody
这是回复。注意：响应包括Preference-Applied：outlook.body-content-type标头，用于确认Prefer：outlook.body-content-type请求标头。
HTTP/1.1 200 OK
Content-type: application/json
Preference-Applied: outlook.body-content-type="text"
Content-length: 1550

"@odata.context":"https://graph.microsoft.com/beta/$metadata#users('cd209b0b-3f83-4c35-82d2-d88a61820480')/messages(subject,body,bodyPreview,uniqueBody)/$entity",

"uniqueBody":{

希望这可以帮助！
