javascript - How do I pass a req.setHeaders method on res.redirect method within the same app.get function? -

var express = require('express'); var app = express();  var port = process.env.port;  app.get('/', function(req, res){    res.json('enter query parameters image search so: https://api.cognitive.microsoft.com/bing/v5.0/images/search?q=cats&count=10 , latest search results enter url ttps://api.cognitive.microsoft.com/bing/v5.0/images/*');  }); 

here app.get method want parameters input user , redirect bing api return search results image search. big api requires api key passed header, ocp-apim-subscription-key: ••••••••••••••••••••••••••••••••. how do this?

app.get('/imagesearch/:image*', function(req, res){     console.log(req.params.image);     console.log(req.query.count);     res.redirect('https://api.cognitive.microsoft.com/bing/v5.0/images/search?q='+req.params.image+'&count='+req.query.count); });  app.listen(port, function(){    console.log('express listening on: '+port);  }); 

since sounds want fetch data remote site , return response original request, can using request module , piping response response original http request.

const request = require('request');  app.get('/imagesearch/:image*', function(req, res){     let options = {         url: 'https://api.cognitive.microsoft.com/bing/v5.0/images/search?q='+req.params.image+'&count='+req.query.count,         headers: {"ocp-apim-subscription-key": "xxxxx"}     };     request(options).pipe(res); });
