Gmail Api可恢复上传Rest（附件大于5MB）

Question

我试图通过Gmail发送Api Api其他邮件附件大于5MB。为了达到这个目标，我试图用可恢复的上传来发送它。这是我的代码。

byte[] ba = System.IO.File.ReadAllBytes(uploadFromPath); 
String base64String = Convert.ToBase64String(ba); 
string url = "https://www.googleapis.com/upload/gmail/v1/users/me/messages/send?uploadType=resumable" 
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest; 
request.Headers.Add("Authorization", "Bearer " + token); 
request.Headers.Add("X-Upload-Content-Type", "message/rfc822"); 
request.Headers["X-Upload-Content-Length"]= base64String.Length.ToString(); 
request.Method = "POST"; 
request.ContentType = "application/json"; 
request.ContentLength = body.Length; 

后，我让我越来越位置

location = res.Headers["Location"]; 

，之后我就与该位置的PUT请求的请求。

我想知道我应该在第一个请求体内插入什么以及第二个请求内应该包含什么。 我看到这篇文章Attaching a file using Resumable upload w/ Gmail API 但代码仅适用于小于5MB的文件。还有什么我应该做的，以完成超过5MB的连接？

实际上有Upload Attachment文档中的样本。

步骤1：启动可恢复会话 可恢复会话发起请求

POST /upload/gmail/v1/users/userId/messages/send?uploadType=resumable HTTP/1.1 
Host: www.googleapis.com 
Authorization: Bearer your_auth_token 
Content-Length: 38 
Content-Type: application/json; charset=UTF-8 
X-Upload-Content-Type: message/rfc822 
X-Upload-Content-Length: 2000000 

{ 
    "id": string, 
    "threadId": string, 
    "labelIds": [ 
    string 
    ], 
    "snippet": string, 
    "historyId": unsigned long, 
    "payload": { 
    "partId": string, 
    "mimeType": string, 
    "filename": string, 
    "headers": [ 
     {

    "parts": [ 
     (MessagePart) 
    ] 
    }, 
    "sizeEstimate": integer, 
    "raw": bytes 
}

HTTP/1.1 200 OK 
Location: https://www.googleapis.com/upload/gmail/v1/users/userId/messages/send?uploadType=resumable&upload_id=xa298sd_sdlkj2 
Content-Length: 0

Content-Length: 2000000 
Content-Type: message/rfc822
