Google REST API - message in an RFC 2822 formatted and base64url encoded string
api, gmail-api, rest
Solution
An example mail could look like this:
From: sender@gmail.com
To: receiver@gmail.com
Subject: Subject Text
The message text goes here
Open up the Developer Tools in your browser and Base64 encode it and replace all `+` with `-`, replace all `/` with `_`, and remove the trailing `=` to make it URL-safe:
btoa(
"From: sender@gmail.com\r\n" +
"To: receiver@gmail.com\r\n" +
"Subject: Subject Text\r\n\r\n" +
"The message text goes here"
).replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '');
This will give you the following data:
`RnJvbTogc2VuZGVyQGdtYWlsLmNvbQ0KVG86IHJlY2VpdmVyQGdtYWlsLmNvbQ0KU3ViamVjdDogU3ViamVjdCBUZXh0DQoNClRoZSBtZXNzYWdlIHRleHQgZ29lcyBoZXJl`
Use this string above as your `raw`-parameter in the API Explorer to send the mail.
Problem
I try the use the - try it of Google REST API - Users.messages: send . There is there a required parameter - `raw` - The entire email message in an RFC 2822 formatted and base64url encoded string. Returned in messages.get and drafts.get responses when the format=RAW parameter is supplied. I checked about RFC 2822 format and seems it should displayed as the sample here , then I encoded it the base64URL with this encoder and paste it the `raw` field of the try it and I get - `Invalid value for ByteString: http://ostermiller.org/calc/encode.html` . Can you provide me a correct `RFC 2822 format` and its corresponding `base64URL` which it would work in the above try it ?
