Send URL parameters in Node,Express JS

Question

I have an endpoint https://www..com

When I make a curl call, I have the endpoint as https://www..com?param1=true

I want to do a similar call from Nodejs, I am not sure if param1 should be passed in headers, concatenated to the endpoint or passed in options. What is the right way to do so?

My Node JS looks like this to make calls to my Node Server amd my file looks as follows,

    app.post('/thisway', function(req, res){
    var ENDPOINT = req.body.endPoint 
//(this gets me till https://<url> part of the endpoint string)
        var urlToHit = ENDPOINT.concat("?param1=true")
    var headers = {
            'Authorization': xxxxx,
            'Accept': '*/*',
            'X-Spark-Service-Instance': xxxxx
        }


    var options= {
        url: urlToHit,
        headers: headers,
        json: {xxxxxx}

          }
       request(options, callback);
}

anything related with this ? https://stackoverflow.com/questions/20089582/how-to-get-url-parameter-in-express-node-js?rq=1 — Ramesh Rajendran, May 31 '17 at 06:31
This gives me an internal server error with not much description. I am not sure with the way I set my URL parameter set to true. — Nagireddy Hanisha, May 31 '17 at 06:32
Post the server logs. "due to some reason" is not helping at all. — str, May 31 '17 at 06:50
so you want to make a post request to `/thisway?variable=true` ? — Gnanesh, May 31 '17 at 07:48
yes. I want to send that "variable" as url parameter. Can you please look at my edited version and suggest if I can pass url parameter as a part of options(like json body)? — Nagireddy Hanisha, May 31 '17 at 07:50
`due to some reason` does not help. You should post the error logs here. — Sean C., May 31 '17 at 07:59

When doing a post it is not necessary to add a query string parameter in the route post. Mostly used for app.get. You can add the details in the JSON string data that you are sending. You can then use the req.body or req.query to get the item. However you can do it this way:

 app.post('/thisway/:variable', function(req, res){

Then you retrieve the parameter using req.param.variable

Good EXAMPLE

You can pass it as you have shown in your example in urlToHit. You don't have to pass it in header or options.

var urlToHit = ENDPOINT.concat("?param1=true")

This should complete the request with the needed parameters. Since even when you are doing a curl call, this is the endpoint you hit, it should be the same endpoint here as well.

In your angularjs make a post request to /thisway?variable=true rather than /thisway and in your router you can configure as following:

app.post('/thisway', function(req, res){
    var variable = req.query.variable;

    if (variable) {
    //do something
    } else {
    //do something
    }
});
