使用 ruby 从 Microsoft graph rest api outlook 消息中提取电子邮件正文

Question

我正在通过 Microsoft Graph 从 Outlook 或 Rest Api 直接从 Ruby 获取电子邮件，而不使用任何 Microsoft SDK。

我面临的问题是无法从 Microsoft returned 的响应中获取电子邮件正文。使用 Ruby 邮件 gem，我尝试通过以下方式解析响应：

 response = HTTParty.get("https://graph.microsoft.com/v1.0/me/messages", headers: headers)

response_body = response.body
parsed_body = JSON.parse(response_body)
returned_email_values = parsed_body.dig('value')
first_email = returned_email_values.first
#I tried mail = Mail.read_from_string(first_email ) and also, mail = Mail.new(first_email )

mail = Mail.read_from_string(first_email )
mail.body.raw_source

其中 return 个：

 "{\"contentType\"=>\"html\", \"content\"=>\"<html>\r\n<head>\r\n<meta http-equiv=\\"Content-Type\\" content=\\"text/html; charset=utf-8\\">\r\n<meta content=\\"text/html; charset=utf-8\\">\r\n</head>\r\n<body>\r\nLet's go&nbsp;\r\n<div><br>\r\n</div>\r\n<div style=\\"font-size:100%; color:#000000\\">\r\n<div>-------- Original message --------</div>\r\n<div>From: Well &lt; **@outlook.com&gt; </div>\r\n<div>Date: 09/01/2018 22:33 (GMT&#43;00:00) </div>\r\n<div>To: **@yahoo.com </div>\r\n<div>Subject: it is httparty </div>\r\n<div><br>\r\n</div>\r\n</div>\r\nhttparty rocks\r\n</body>\r\n</html>\r\n\"}"

我该如何解析它才能得到电子邮件正文，没有 html markdown 应该 return httparty rocks.

作为参考，这里是 link 到 Microsoft's documentation for the api，这是 return 发给我的完整 api 回复：

可能最简单的方法是要求服务器 return plain-text 版本的 body。来自 the docs:

Prefer: outlook.body-content-type：body 和 uniqueBody 属性的格式 return。值可以是 "text" 或 "html".如果未指定 header，则 body 和 uniqueBody 属性以 HTML 格式 returned。可选。

这是我在 Postman 中指定 header 的方式：
