I am currently trying to send emails which consist of 3 components: plain text, attachments and html, using gmail api in reactjs. Using my code to send the email now, I am only able to receive the attachments and html. Below is the code I used to send the email:
for (i=0; i<email.attachment.length; i++) {
let content = email.attachment[i].data.split(",")[1];
let attachment = ['--012boundary01\r\n',
'Content-Type: ' + email.attachment[i].type + '\r\n',
'MIME-Version: 1.0\r\n',
'Content-Transfer-Encoding: base64\r\n',
'Content-Disposition: attachment; filename=' + email.attachment[i].name + '\r\n\r\n',
content, '\r\n\r\n'].join('');
console.log(attachment)
attachments += attachment
};
let mail = [
'Content-Type: multipart/mixed; boundary="012boundary01"\r\n',
'MIME-Version: 1.0\r\n',
'To: ' + email.to + '\r\n',
'Subject: ' + email.subject + '\r\n\r\n',
'--012boundary01\r\n',
'Content-Type: multipart/alternative; boundary=012boundary02\r\n\r\n',
'--012boundary02\r\n',
'Content-Type: text/plain; charset=UTF-8\r\n\r\n',
email.body + '\r\n\r\n',
'--012boundary02\r\n',
'Content-Type: text/html; charset=UTF-8\r\n',
'Content-Transfer-Encoding: quoted-printable\r\n\r\n',
'<h1>HELLO</h1>\r\n\r\n',
'--012boundary02--\r\n',
attachments,
'--012boundary01--'
].join('');
The content variable is the base64 encoded string of my attachment.
The final mail variable will look something like this:
Content-Type: multipart/mixed; boundary="012boundary01"
MIME-Version: 1.0
To: [email protected]
Subject: test again
--012boundary01
Content-Type: multipart/alternative; boundary=012boundary02
--012boundary02
Content-Type: text/plain; charset=UTF-8
testing123
--012boundary02
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
<h1>HELLO</h1>
--012boundary02--
--012boundary01
Content-Type: image/jpeg
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename=1x1_red_pixel.jpeg
(base64 encoded string here)
