How to send facebook api batch request with node.js - facebook

Question

How do I send facebook api batch request with node.js?
FB's examples do not work.

Answer 1

but I finally got danwong/restler.js to work like this:
exports.updateUserFriends = function (userData, next) {
var TOKEN = userData[1];
var fbID = userData[3].id;
var batchreq = {};
batchreq.batch = [];
batchreq.batch.push({"method":"GET", "relative_url":fbID+"/"});
batchreq.batch.push({"method": "GET", "relative_url":fbID+"/friends?limit=50"});
restler.post('https://graph.facebook.com?access_token='+TOKEN,
{data:"batch="+JSON.stringify(batchreq.batch)})
.on('complete', function(data) {
console.log(data);
return next;
});
};
So I thought I'd post this to save someone else a bit of frustration.

First thing to note is that, "Only POST is allowed for batch requests" in FB Api.
var https = require('https');
var url = '/?access_token='+ YOUR_ACCESS_TOKEN_HERE,
batch=[{
"method":"GET",
"relative_url":page + "/insights"
}, {
"method": "GET",
"relative_url":page
}];
url = url + '&batch=' + JSON.stringify(batch);
console.log(url);
var options = {
host:'graph.facebook.com',
path:url,
method: 'POST'
};
var req =https.request(options, function(res){
console.log('STATUS: ' + res.statusCode);
console.log('HEADERS: ' + JSON.stringify(res.headers));
res.setEncoding('utf8');
var body='';
res.on('data', function(chunk){
// console.log("body:" + chunk);
body += chunk;
});
res.on('end', function(){
var fbRes = JSON.parse(body);
console.log(fbRes);
});
});
req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
req.end();
