Question

I need to trigger a request in my node.js app. My app has a route and when it runs I am trying to hit a url that is built dynamically. So all I need is to trigger a RESt API call to somethinglike:

"https://www.domainname.com/sometext/"+ var1 +"/someothertext"

So I tried this:

var options = {
    host: 'www.domainname.com',
    port: 80,
    path: '/1.0/'+var1,
    method: 'GET'
};

//  trigger request 
request(options, function(err,response,body) {
.......
});

When I run this I get this error:
options.uri is a required argument

So, my goal here is to trigger the request that hits a dynamically built url. If I had a static url I could plug in the request, it would work fine.

Infact I tried to do this:

request("https://www.domainname.com/1.0/456", function(err,response,body) {
.......
});

and this works fine.

BUT I am trying to build the url (path) dynamically with var1 and that doesn’t work.

Any suggestion on how to do this?

Answer 1

You need a URL or an URI in the options that you pass as the first arguments to the request function

And the reason that request("https://www.domainname.com/1.0/456",function(err,response,body) {
does not fail is because you are providing the url as the first argument

So change your options object to

var options = {
    url: 'https://www.domainname.com/sometext/'+ var1,
    port: 80,
    method: 'GET'
};

You can try trimming the value in var1 like
var1 = var1.replace(/^\s*|\s*$/g, '');

That should remove the space.
