在developer.microsoft.com/en-us/graph/graph-explorerI上，我尝试在OneNote中发布创建页面请求，并且在请求标头中填充的默认代码如下所示：
KEY: Content-type VALUE: multipart/form-data
boundary MyPartBoundary198374
请求主体如下所示：
--MyPartBoundary198374
Content-Disposition:form-data; name="Presentation"
Content-Type:text/html
<!DOCTYPE html>
<html>
<head>
<title>A page with <i>rendered</i> images and an <b>attached</b> file</title>
<meta name="created" content="2015-07-22T09:00:00-08:00" />
</head>
<body>
<p>Here's an image from an online source:</p>
<img src="http://..." alt="an image on the page" width="500" />
<p>Here's an image uploaded as binary data:</p>
<img src="name:imageBlock1" alt="an image on the page" width="300" />
<p>Here's a file attachment:</p>
<object data-attachment="FileName.pdf" data="name:fileBlock1" type="application/pdf" />
</body>
</html>
--MyPartBoundary198374
Content-Disposition:form-data; name="imageBlock1"
Content-Type:image/jpeg
... binary image data ...
--MyPartBoundary198374
Content-Disposition:form-data; name="fileBlock1"
Content-Type:application/pdf
... binary file data ...
--MyPartBoundary198374--
响应预览仍然给我一个错误，说：
Page create requests require the content to be multipart, with a presentation part.
考虑到请求标头和请求主体是由Microsoft生成的，这不应该吗？我有正确的section-id可以写到页面，所以我很困惑。
我所缺少的是在请求标头中，而不是将其值multipart/form-data更改为text/html
