Open Weather Api我不知道为什么它不起作用Exprees Node.js

Question

我找不到问题，我不知道逻辑是否不正确或缺少某些内容，请帮忙

const express = require('express');
const router = express.Router();
const { check, validationResult } = require('express-validator');
const auth = require('../../middleware/auth');
const request = require('request');
const config = require('config');
const key = config.get('WeatherKey');

const Post = require('../../models/Post');
const Profile = require('../../models/Profile');
const User = require('../../models/User');

以上所有呼叫

router.post(
  '/',
  [
    auth,
    [
      check('cityname', 'cityname is required')
        .not()
        .isEmpty()
    ]
  ],
  async (req, res) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      return res.status(400).json({ errors: errors.array() });
    }
    try {
      const user = await User.findById(req.user.id).select('-password');
      const cityname = req.body.name;
      const url = `http://api.openweathermap.org/data/2.5/weather?q=${cityname}&units=imperial&appid=${key}`;

Api请求功能

      request(url, (error, response, body) => {
        if (error) console.error(error);
        if (response.statusCode !== 200) {
          res.status(404).json({ msg: 'No Temp Available' });
        }
        res.json(JSON.parse(body));
      });

捕获错误

    } catch (err) {
      console.error(err.message);
      res.status(500).send('Server Error');
    }
  }
);

导出模块

module.exports = router;
