指定节点获取以获取JSON

Question

Is there a way to specify node-fetch to request for JSON for a GET request? The external api endpoint I'm trying to reach sends back xml.

I know I can do something like this on the front-end, but can I do this in my node-server?

const response = fetch(url, {
  method: 'GET',
  headers: {
    'Accept': 'application/json',
  }
});

server.js

const express = require('express')
const path = require('path')
const bodyParser = require('body-parser')
const fetch = require('node-fetch')

const app = express()
const port = process.env.PORT || 5000

app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))

app.get('/buses/location', (req, res) => {
  const apiURL = `${TRANSLINK_URL}${TRANSLINK_TOKEN}`

  fetch(apiURL)
    .then(response => {
      if (response.ok) {
         response.json()
         .then((data) => {
             res.json(data)
         })
        .catch(err => {
          console.log(err)
        })
      }
      else {
        res.sendStatus(response.status)
      }
    })
    .catch(error => {
        console.log(error)
    })
})

This code include the application/json request header and it is refactored with async/await , you should use that instead of callbacks

app.get('/buses/location', async (req, res) => {
  const apiURL = `${TRANSLINK_URL}${TRANSLINK_TOKEN}`;
  try {
    const response = await fetch(apiURL, { headers: { 'Content-Type': 'application/json' }});
    const jsonResponse = await response.json();
    res.send(jsonResponse);
  }
  catch (e){
    console.log(e);
  }
})

However, the server you are reaching must support json responses when requested, otherwise you will have to manage your data as xml
