javascript - 401 unauthorized except through browser -

i've been trying html request, using url works in browser somehow results in 401 unauthorized error when run code. problem did provide authentication; url of form

http://username:password@url?param=value

it succeeds in firefox , chrome (i went through incognito mode avoid cookies), google's postman app, despite trying several other http request methods return unauthorized error. i've run through rest api , xmlhttprequest, command line.

any ideas on causing this? or, better, if someone's had similar problem , has solution?

(note: i'm pretty new whole thing, not sure if clear/detailed enough. i'll best elaborate if needs.)

edit: here's idea of original code running:

var func = function() {   var options = {     baseurl: server,     uri: '/device.cgi',     qs: {       param1: value1,       param2: value2     }   };   request(options, function(err, response, body) {     if (err) console.log(err);     else console.log(body);   }); }; 

i ran

function httpget(theurl) {     var xmlhttp = new xmlhttprequest();     xmlhttp.open( "get", theurl, false ); // false synchronous request     xmlhttp.send( null );     return xmlhttp.responsetext; } 

from this question , got same unauthorized result.

and because apparently device i'm using fine post well,

var func = function () {   var formdata = {     form: {       param1: value1,       param2: value2     }   };   request.post(server + 'device.cgi', formdata, function (err, response, body) {     if (err) {       console.log(err);     }     else console.log(body);   }).auth(userid, userpass); }; 

still same result.

http://username:password@url?param=value

the browser taking url, , creates basic http authorization header you.

node.js not you, , must set authorization header in code.

var http = require('http');  var options = {   host: 'www.tempuri.org',   path: '/helloworld/',   headers: {     'authorization': 'basic qwxhzgrpbjppcgvuu2vzyw1l'   } };  http.request(options, function(response) {   var body = '';   response.on('data',function(c) {     body+= c;   })   response.on('end',function() {     console.log(body)   }) }).end(); 

the following links discuss basic auth, how browser encodes data in url, , how implement in node.js:

• basic access authentication (wikipedia)
• can pass user/pass http basic authentication in url parameters? (serverfault)
• basic http authentication in node.js using request module (hay kranen)
