gmail 发送 api 失败，在流星中出现错误代码 400

Question

我正在尝试在我的流星应用程序中使用 gmail api 发送邮件，但返回以下错误，

Error in calendar insert: Error: failed [400] {  "error": {   "errors": [    {        "domain": "global",     "reason": "invalidArgument",     "message": "'raw' RFC822 payload message string or uploading message via /upload/* URL required"    }   ],   "code": 400,   "message": "'raw' RFC822 payload message string or uploading message via /upload/* URL required"  } } 

我已经尝试了以下，

"sendGmail": function(str) {
    this.unblock();
        var url = "https://www.googleapis.com/gmail/v1/users/me/messages/send";

        var encodedMail = new Buffer(str).toString("base64").replace(/\+/g, '-').replace(/\//g, '_');

        try {
        Meteor.http.post(url, {
            'headers' : { 
                'Authorization': "Bearer " + Meteor.user().services.google.accessToken,
                'Content-Type': 'application/json' 
            },
            'body': JSON.stringify({
                "raw": encodedMail
            })
          });
        } catch(e){
            console.log("Error in calendar insert: " + e);
        } finally {
          return true;  
        }
}

将以下字符串值作为参数传递：

    var str = "Content-Type: text/plain; charset=\"UTF-8\"\n" +
        "MIME-Version: 1.0\n" +
        "Content-Transfer-Encoding: 7bit\n" +
        "to: arunmail2u@gmail.com\n" +
        "from: arunsugan08@gmail.com\n" +
        "subject: Meteor test mail\n\n" +

    "Hi, this is test mail from meteor application";

     Meteor.call('sendGmail', str);

正文字符串为content，而不是body。 Check the documentation.

content - 采用纯字符串并将其设置在 HTTP 请求正文中。
