coinbase-api - {error: "invalid_client", error_description: "Client authenti .... authentication method."} COINBASE OAUTH API ISSUE

Question

这是使用 COINBASE API 成功授权后请求访问令牌的代码

router.get('/auth/coinbase/token', function (req, res) {
  var body = {
    "grant_type": "authorization_code",
    "code": req.query.code,
    "client_id": process.env.COINBASE_CLIENT_ID,
    "client_secret": process.env.COINBASE_CLIENT_SECRET,
    "redirect_uri": process.env.COINBASE_CALLBACK_URL
  };

  console.log(body);
  request.post({
    url: 'https://api.coinbase.com/oauth/token',
    headers: {
      'Content-Type': 'application/json'
    },
    json: {
      "grant_type": "authorization_code",
      "code": req.query.code,
      "client_id": process.env.COINBASE_CLIENT_ID,
      "client_secret": process.env.COINBASE_CLIENT_SECRET,
      "redirect_uri": process.env.COINBASE_CALLBACK_URL
    }
  }, function (error, response, body) {
    console.log('error:', error); // Print the error if one occurred and handle it
    console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
    res.send(body)
  });
});

但是在发送发布请求时，我收到此错误

{error：“invalid_grant”，error_description：“提供的授权授权无效，过期……化请求，或已发布给另一个客户端。”}

帮我解决这个问题。谢谢
