const express = require('express');
   
const fetch = require('node-fetch');

const router = express.Router();
    
const CLIENT_ID = 'CLIENT_ID ';
const CLIENT_SECRET = 'CLIENT_SECRET';
const creds = btoa(`${CLIENT_ID}:${CLIENT_SECRET}`);
const redirect = encodeURIComponent('http://localhost:50451/callback');
    
router.get('/login', (req, res) => {
   res.redirect('https://flow.polar.com/oauth2/authorization?response_type=code&client_id=client_id');
});

router.get('/list', catchAsync(async (req, res) => {
   if (!req.query.code) throw new Error('NoCodeProvided');
      const code = req.query.code;
      const creds = btoa(`${CLIENT_ID}:${CLIENT_SECRET}`);
   
      fetch('https://polarremote.com/v2/oauth2/token', {
         method: 'POST',
         data : {
            'grant_type' : 'authorization_code',

             'Accept':' application/json;charset=UTF-8'
         }
      })
      .then(function(response) {
          return response.json();
          console.log(response.json());
       }).then(function(body) {
           console.log(body); 
           res.send('POST');
       });
 })

当我在 URI 中传递参数时，我遇到同样的问题，我的意思是

https://polarremote.com/v2/oauth2/token?grant_type=authorization_code&code=SplxlOBeZQQYbYS6WxSbIA

。当我使用 @PHP

curl_setopt($connection, CURLOPT_POSTFIELDS, 'grant_type=authorization_code&code=SplxlOBeZQQYbYS6WxSbIA');

时效果很好。
