I have been playing around trying to sign a request using nodeJS but it seems to be producing a different hash result when using the node crypto.createHmac. When using the the php hash_hmac it works perfectly I was just wondering if anybody as achieved making a successful request in node.

Hi Daniel,

Following code works at my end. Please give it a try and let us know if it works for you also.

var http = require('http');<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />

var fs = require('fs');

var crypto = require('crypto')

, app_sid='77*****-****-****-****-***********'

, app_key = '89*****************'

, signature;

var url_to_sign = 'http://api.aspose.com/v1.1/words/Sample.doc?format=pdf&appSID='+app_sid;

var raw_signature = crypto.createHmac('sha1', app_key).update(url_to_sign.replace(/\s/g, '%20')).digest('base64');

signature = raw_signature.replace(/\//g, '%2F').replace(/=/g, '');

var signed_uri = url_to_sign.replace(/\s/g, '%20')+'&signature='+signature;

var file = fs.createWriteStream("Output.pdf");

var request = http.get(signed_uri, function(response) {

response.pipe(file);

});

console.log('Output file saved as Output.pdf');

Best Regards,
