I have a project that receives POST data from a camera. This data include a URL for a JPG image. I then use this URL received in the POST data to make a requerst to the camera to retreieve the image with a GET.
The issue is that the camera response indicates that I have requested the same URL twice:
const fs = require('fs');
var express = require('express')
var multer = require('multer')
var upload = multer({ storage: multer.memoryStorage() })
var app = express()
// handler for receiving data from camera - list on test port 3000
app.post('/test', upload.fields([ {name: 'event'}, {name: 'image'} ] ), (req, res) => {
var data = JSON.parse(req.files.event[0].buffer.toString())
res.send(200)
const url = camera_url + data.imagesURI[0];
console.log(url) // Clicking on this image in the console shows the plate OK
const PlateImage = httpClient.request(url, options).then(function (result) {
console.log('this is url requested : ', url)
console.log('response status from camera : ', result.res.statusCode);
console.log('full result', result)
console.log('this is data to string ', result.data.toString('base64'))
return result.data.toString('base64')
})
PlateImage.then(function(image) {
sendToOtherServer(req, data, image )
});
})
But my responses look like this (first one is OK 200 then the other are 400)

what is with the requestURLs array in the response?
