I have google drive sign in feature in my react nodejs application. When ever a user clicks on sign in, I am using Google oauth2 to get code and that to get access token and refresh token using client ID and secret. I am saving these tokens and expiry in my database. Now, I want to use the refresh to get access token so that my access token never expires. Basically, I want the user to be always signed in. I am creating a post request to token to get the access token using the refresh token. This is my code:

try{ 
 axios.post('/https://www.googleapis.com/oauth2/v3/token',{
  client_id: clientId,
  client_secret: secret,
  refresh_token: rToken
  grant_type: rToken
 })
 .then((response) => { 
  console.log("response = ", response)
 }).catch((error) => {
  console.log("error in getting token: = ", error)
 })
} catch(err) { 
 console.log("error = ", err)
}

I am getting Error: connect ECONNREFUSED

I tried passing grant_type: refresh_token buy this gave reference error: refresh_token is not defined

Where am I going wrong?

CodePudding user response：

First, you are using the axios.post() method to make a request to the Google OAuth2 token endpoint, but the URL you provided is incorrect. The correct URL for the token endpoint is https://www.googleapis.com/oauth2/v3/token, not /https://www.googleapis.com/oauth2/v3/token.

Here is an example of how you could correctly make a request to the Google OAuth2 token endpoint to get an access token using a refresh token:

const axios = require('axios');

const clientId = 'your-client-id';
const secret = 'your-client-secret';
const rToken = 'your-refresh-token';

try {
  axios.post('https://www.googleapis.com/oauth2/v3/token', {
    client_id: clientId,
    client_secret: secret,
    refresh_token: rToken,
    grant_type: 'refresh_token'
  })
  .then((response) => {
    console.log("response = ", response);
  })
  .catch((error) => {
    console.log("error in getting token: = ", error);
  });
} catch(err) {
  console.log("error = ", err);
}

CodePudding user response：

To get an access token using a refresh token in Google OAuth2, you can use the refresh_token grant type in the Google OAuth2 API. To do this using axios, you can make a POST request to the https://oauth2.googleapis.com/token endpoint with the following parameters in the request body:

• refresh_token: The refresh token that you received when you initially authenticated the user.
• client_id: The client ID for your application.
• client_secret: The client secret for your application.
• grant_type: The grant type, which should be set to refresh_token.

Here's an example of how you might make this request using axios:

axios.post('https://www.googleapis.com/oauth2/v3/token', {
  refresh_token: 'your-refresh-token',
  client_id: 'your-client-id',
  client_secret: 'your-client-secret',
  grant_type: 'refresh_token',
})
  .then((response) => {
    // Handle the response
  })
  .catch((error) => {
    // Handle any errors
  });

This will return a response with the new access token in the access_token field. You can then use this access token to make authorized requests to the Google API on behalf of the user.
