In postman, I can successfully make this request:

And get this response:

Now I want to do the same request in my server.js file in node.js:

const fetch = require('node-fetch')

const SEN_URL =  http://www.sentiment140.com/api/bulkClassifyJson // URL of sentiment analysis

app.get('/api/sentimenttest', async (req, res) => {

  try{

    var sentiments = await fetch(SEN_URL, {method: POST, body: {data: [{text: I love you}, {text: I hate you}]}})

    console.log(sentiments)

    res.send(sentiments)

  }catch(error){

    console.log(error)

  }

})

This doesn't work. Here's what shows up in the browser when I go to localhost:5000/api/sentimenttest:

{size:0,timeout:0}

and here's the console output:

 Response {

   size: 0,

   timeout: 0,

   [Symbol(Body internals)]: 

    { body: 

       PassThrough {

         _readableState: [ReadableState],

         readable: true,

         _events: [Object],

         _eventsCount: 2,

         _maxListeners: undefined,

         _writableState: [WritableState],

         writable: false,

         allowHalfOpen: true,

         _transformState: [Object] },

      disturbed: false,

      error: null },

   [Symbol(Response internals)]: 

    { url: 'http://www.sentiment140.com/api/bulkClassifyJson',

      status: 200,

      statusText: 'OK',

      headers: Headers { [Symbol(map)]: [Object] } } }

Since the request works just fine in postman, I think that the problem is with node-fetch, or the way that I use it, specifically how the body parameter is provided in the fetch() call. It seems like the API call does not contain what I want it to, since in the browser it says size:0.

What should I do to fix this?
