Using Parse.com REST API with query in node.js - how to use data-encode from CURL

Question

I am trying to replicate the example of the parse.com rest API below:

curl -X GET \
  -H "X-Parse-Application-Id: APP_ID" \
  -H "X-Parse-REST-API-Key: API_KEY" \
  -G \
  --data-urlencode 'where={"playerName":"John"}' \
  https://api.parse.com/1/classes/GameScore

So, based on an example found on Stackoverflow, I implemented the function:

var https = require("https");
exports.getJSON = function(options, onResult){

    var prot = options.port == 443 ? https : http;
    var req = prot.request(options, function(res){
        var output = '';
        res.setEncoding('utf8');
        res.on('data', function (chunk) {
            output += chunk;
        });

        res.on('end', function() {
            var obj = JSON.parse(output);
            onResult(res.statusCode, obj);
        });
    });

    req.on('error', function(err) {
    });

    req.end();
};

which I call like that :

var options = {
host: 'api.parse.com',
port: 443,
path: '/1/classes/GameScore',
method: 'GET',
headers: {
    'X-Parse-Application-Id': 'APP_ID',
    'X-Parse-REST-API-Key': 'APP_KEY'
}
};

rest.getJSON(options,
    function(statusCode, result)
    {
        // I could work with the result html/json here.  I could also just return it
        //console.log("onResult: (" + statusCode + ")" + JSON.stringify(result));
        res.statusCode = statusCode;
        res.send(result);
    });

My question is, how do I send the "--data-urlencode 'where={"playerName":"Sean Plott","cheatMode":false}' bit? I tried appending it to the path by setting the path in the options like that: '/1/classes/GameScore?playerName=John, but that didn't work, I received all the GameScore, not the ones from John

Why don't you just use the official Parse JavaScript SDK? Also, you can look at its source code to see how to use the rest api. npmjs.org/package/parse — bklimt

It seems to be expecting where as the key/name with the value the entire JSON value:

/1/classes/GameScore?where=%7B%22playerName%22%3A%22John%22%7D

You can get this with querystring.stringify():

var qs = require('querystring');

var query = qs.stringify({
    where: '{"playerName":"John"}'
});

var options = {
    // ...
    path: '/1/classes/GameScore?' + query,
    // ...
};

// ...

Optionally with JSON.stringify() to format the value from object:

var query = qs.stringify({
    where: JSON.stringify({
        playerName: 'John'
    })
});

It is helpful answer. But I have one question, how about PUT(update)?

@smartworld-konoha You can use req.write(JSON.stringify({ ... })); to provide the object in the request's body, along with an appropriate Content-Type request header, going by the current Parse Server docs. – Although it uses URL-encoding rather than JSON, an example is available in the docs for http.request().
