Failed sending mail through google api in nodejs

Question

I'm trying to send an email through Google API.

I'm using googleapis for Google API access in node.js .

My issue is that when I try to send a simple mail with no attachments, I get the following error:

'raw' RFC822 payload message string or uploading message via /upload/* URL required

I didn't define in my request that there is an attachment and I don't see any error in the email addresses.

Please help.

My code:

    var google = require('googleapis');
    var gmailClass = google.gmail('v1');

    var email_lines = [];

    email_lines.push("From: \"Some Name Here\" <rootyadaim@gmail.com>");
    email_lines.push("To: hanochg@gmail.com");
    email_lines.push('Content-type: text/html;charset=iso-8859-1');
    email_lines.push('MIME-Version: 1.0');
    email_lines.push("Subject: New future subject here");
    email_lines.push("");
    email_lines.push("And the body text goes here");
    email_lines.push("<b>And the bold text goes here</b>");

    var email =email_lines.join("\r\n").trim();

    var base64EncodedEmail = new Buffer(email).toString('base64');

    gmailClass.users.messages.send({
        auth: OAuth2Client,
        userId: "me",
        message: 
        {
             raw: base64EncodedEmail
        }           
      },
    function(err, results){});

Did you try making `base64EncodedEmail` url-safe? Example: `base64EncodedEmail.replace(/\+/g, '-').replace(/\//g, '_')` — mscdex, Aug 08 '14 at 16:05
@mscdex it did change parts in the string but I still got the same error — Hanoch Giner, Aug 08 '14 at 16:29
I have the same issue. The API seams to be responding the same no matter what I send. — Eduárd Moldován, Aug 23 '14 at 22:46
I even tried sending back a raw message that I received as a response from the API itself. I got the same error message. — Eduárd Moldován, Aug 23 '14 at 22:50

Changes were made to version 1.0.3 of the google api. Try using the following syntax:

gmailClass.users.messages.send({
    auth: OAuth2Client,
    userId: "me",
    resource: 
    {
         raw: base64EncodedEmail
    }           
  }

Make sure that base64EncodedEmail is url safe. You can use the base64EncodedEmail.replace(/\+/g, '-').replace(/\//g, '_') code posted by mscdex. This syntax worked for v. 1.0.11

Thank you for posting! Was wondering why some of my code stopped working. Where did you find out about this API update? I ask because even Google's documentation still has it listed as `message`, not `resource` as of 10-21-14: https://developers.google.com/gmail/api/v1/reference/users/messages/send – rog Oct 22 '14 at 05:24
