Get data from http request in node.js

Question

When I use response.on('data' callback) I get the data as soon as it is received. This results in the data getting passed part by part.

I wish to get the data all together and call the parser.parseString(chunk,parseData). How do I achieve this?

The following is my code.

var request = https.request(options, function(response) {
    response.setEncoding('utf8');

    response.on('data', function (chunk) {
    console.log('BODY: ', chunk);

    //parser.parseString(chunk,parseData);       
    });

    response.on('end', function () {
        console.log('The end');
    });

});

request.on('error', function(e) {
    console.log('problem with request: ' + e.message);
});

request.write(str);    
request.end();
}

You should create variable, where you'll be writing document data

var document;
response.on('data', function(chunk) {
    document += chunk;
}

Then you should trigger your parser at end of document

response.on('end', function() {
    parser.parseString(document, parseData);
});

If you consider or are using the Express framework, see if the body-parser middleware meets your need (c.f. https://github.com/expressjs/body-parser)
