如何将令牌作为值返回？节点js

Question

我该如何解决这个问题？我发出了一个post请求来获取token，但是当我返回它时，它返回为未定义，但是当我打印它时，它显示token OK。

function getToken() {

  // The req.query object has the query params that
  // were sent to this route. We want the `code` param
  axios({
    // make a POST request
    method: "post",
    // to the Github authentication API, with the client ID, client secret
    // and request token
    url: ` https://backstage.taboola.com/backstage/oauth/token?client_id=${clientID}&client_secret=${clientSecret}&grant_type=client_credentials`,
    // Set the content type header, so that we get the response in JSOn
    headers: {
      accept: "application/json",
    },
  }).then((response) => {
    // Once we get the response, extract the access token from
    // the response body
    accessToken = response.data.access_token;
    //console.log(accessToken);
    return(accessToken);
  });
};

你可以这样做

async function getToken() {

  // The req.query object has the query params that
  // were sent to this route. We want the `code` param
  const response = await axios({
    // make a POST request
    method: "post",
    // to the Github authentication API, with the client ID, client secret
    // and request token
    url: ` https://backstage.taboola.com/backstage/oauth/token?client_id=${clientID}&client_secret=${clientSecret}&grant_type=client_credentials`,
    // Set the content type header, so that we get the response in JSOn
    headers: {
      accept: "application/json",
    },
  });
  return response.data.access_token
};

const token = await getToken();
console.log(token)
