Axios set Content-Length manually, nodeJS

Question

Is there a way to send a post request in nodeJS and specify th content-length.

I tried (using axios):

let data = `Some text data...........`;

let form = await Axios.post(
    "url.......",
    data,
    {
        headers: {
            Authentication: "token.....",
            "Content-Type": "multipart/form-data; boundary=c9236fb18bed42c49590f58f8cc327e3",
            //set content-length manually 
            "Content-Length": "268"
        }
    }
).catch(e => e);

It doesn't work, the length is set automatically to a value other then the one I pass.

I am using axios but open to using any other way to post from nodeJS.

In Axios, If data is present it will set length calculated from data, so even if you pass header content-length, it will be overridden by code:

Check this out for more details: https://github.com/axios/axios/blob/master/lib/adapters/http.js

Using http or https module you can do:

const https = require('https')

const data = JSON.stringify({
  key:values
})

const options = {
  hostname: 'example.com',
  port: 443,
  path: '/testpath',
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'Content-Length': data.length
  }
}
const req = https.request(options, (res) => {
  console.log(`statusCode: ${res.statusCode}`)

  res.on('data', (d) => {
    process.stdout.write(d)
  })
})

req.on('error', (error) => {
  console.error(error)
})

req.write(data)
req.end()
