oauth2Client.getToken missing refresh_token
google-api-nodejs-client, javascript, node.js, oauth-2.0
Solution
The `refresh_token` is only sent when the user initially authorizes your app with their account. So it the `getToken` function only returns it the first time (because you should store it). Added `approval_prompt: "force"` to the `generateAuthUrl` options, and I can get it every time.
Problem
I have a small express server that has two routes. Then it writes the json tokens to a file (I know very insecure). For some reason there's no `refresh_token`. In the docs theres a comment that `offline` for `access_type` gets `refresh_token`, which is set and it's still not working ``` access_type: 'offline', // 'online' (default) or 'offline' (gets refresh_token) ``` Here's the express server, sorry if the promises throw anyone off. ``` var Promise = require("bluebird") var express = require('express') var app = express() var google = require('googleapis') var OAuth2 = google.auth.OAuth2 var clientSecrets = require("./client_secrets.json") var oauth2Client = new OAuth2(clientSecrets.web.client_id, clientSecrets.web.client_secret, clientSecrets.web.redirect_uris[0]); oauth2Client.getToken = Promise.promisify(oauth2Client.getToken) var fs = Promise.promisifyAll(require("fs")) app.get('/google', function (req, res) { var url = oauth2Client.generateAuthUrl({ access_type: 'offline', scope: "https://www.googleapis.com/auth/drive" }) return res.redirect(url) }) app.get('/oauth2callback', function (req, res) { return oauth2Client.getToken(req.query.code).then(function(tokens){ fs.writeFileAsync("./tokens.json", JSON.stringify(tokens), "utf8"); return res.json(tokens) }).catch(function(err){ return res.redirect("/google") }) }) var server = app.listen(3000, function () {}) ```
