node.js http request example

A http server acting as a google reverse geocoder API proxy.

You just need to pass in long/lat as querystrings, for example, "localhost/?hi=there&long=37&lat=37". I put the hi=there in there because node querystring module parses strangely...

	var http = require('http'),
	q = require('querystring')
	http.createServer(function (req, res) {
	//create the geo long/lat path
	var url=["/maps/geo?q="
	,q.parse(req.url)["long"]
	,","
	,q.parse(req.url)["lat"]
	,"&output=json&sensor=false"].join(""),
	//create the options to pass into the get request
	options={host:"maps.google.com"
	,path:url};
	//a little lightweight logging to watch requests
	console.log("url:",options.host+options.path);
	console.log("requrl:",req.url);
	//make the request server side
	http.get(options,function(response){
	//console.log("hi",response);
	res.writeHead(200, {'Content-Type': 'text/plain'});
	var pageData = "";
	response.setEncoding('utf8');
	//stream the data into the response
	response.on('data', function (chunk) {
	pageData += chunk;
	});
	//write the data at the end
	response.on('end', function(){
	res.write(pageData);
	res.end();
	});
	});
	}).listen(80);
