请问，这里哪里出现逻辑错误了？

var getRawBody = require('raw-body'); const Url = require('url'); const API_SERVER = 'https://api.dingtalk.com'; const API_VERSION = 'v1.0'; const appType = 'XXXX';

exports.handler = (req, resp, context) => { resp.setHeader('Content-type', 'application/json'); getRawBody(req, function (err, body) { post( ${API_SERVER}/${API_VERSION}/yida/apps/temporaryUrls/${appType}, {

  },
  function (data) {
    data = JSON.parse(data);
      var respBody = new Buffer.from(JSON.stringify(data));
      resp.setStatusCode(200);
      resp.send(respBody);
    },
    req.queries.accessToken
);

}); };

function post(url, data, fn) { data = data || {}; let parse_u = Url.parse(url, true); let isHttp = parse_u.protocol == 'http:'; let options; options = { host: parse_u.hostname, port: parse_u.port || (isHttp ? 80 : 443), path: parse_u.path, method: 'get', json: true, headers: { 'Content-Type': 'application/json', 'x-acs-dingtalk-access-token': accessToken }, }; let req = require(isHttp ? 'http' : 'https').request(options, function (res) { let _data = ''; res.on('data', function (chunk) { _data += chunk; }); res.on('end', function () { fn != undefined && fn(_data); }); }); req.write(JSON.stringify(data)); req.end(); }
