node.js - 如何使用来自 Ebay 的刷新令牌获取 access_token？

Question

我正在尝试从我从 eBay 获得的刷新令牌中获取 access_token。我正在使用 Axios，但我不断收到不支持请求中的授权类型错误。

  const refreshToken = 'xxxxxxxx';
  const appID = 'xxxxxxx';
  const certID = 'xxxxxx';
  const scopes = [
        'https://api.ebay.com/oauth/api_scope',
        'https://api.ebay.com/oauth/api_scope/sell.fulfillment',
        'https://api.ebay.com/oauth/api_scope/sell.account',
        'https://api.ebay.com/oauth/api_scope/sell.inventory'
  ]
  const params = {
    grant_type: 'refresh_token',
    refresh_token: refreshToken,
    'scope': encodeURI(scopes.join(" ")),
    // scope: scopes,
  

const token = Buffer.from(`${appID}:${certID}`);
const URL = 'https://api.ebay.com/identity/v1/oauth2/token'
const { data } = await axios.post(URL, params, {
      'headers': {
        'Authorization': `Basic ${token.toString('base64')}`,
        'Content-Type': 'application/x-www-form-urlencoded',
      },
    })

事实证明，您必须使用节点的 UriEncode 对整个请求正文进行编码querystring.encode()：

const qs = require("querystring")
...
const { data } = await axios.post(URL, qs.encode(params), {
  'headers': {
    'Authorization': `Basic ${token.toString('base64')}`,
    'Content-Type': 'application/x-www-form-urlencoded',
  },
})
