The backend is not receiving the variable through RESTful communication

I'm attempting to pass the word "hello" to the backend of my code using the URL. However, instead of sending the string "hello" to my Java backend code, it's sending an empty string.

Below is my backend code:

@GET
@Path("getJob/{stepName}")
@Produces(MediaType.APPLICATION_JSON)
public List<Step> getStepByName(@PathParam("stepName") String stepName) {
    String x = stepName;
    System.out.println(x);
    return null;

            //List<ModuleProcCount> pusher = statements.inMod(dbc,theReader);
            //for(ModuleProcCount p : pusher) {
            //  input.add(p.modName + " " + p.modCount);
            //}
            //  return result;


        }

And here is my JavaScript:

performanceApp.controller("homectrl", function($scope, $http){
    var x = "rest/performance/getJob/hellp";
    $http.get(x).then(function(response){

    }); 


});

I'm not sure what I'm doing wrong or what the issue is with this code, as it seems pretty straightforward.

Answer №1

Although I may not fully grasp all of your points, it seems like you are utilizing AngularJS. However, it appears that there may be an issue with the header of your request. To clarify this, consider modifying the header in your client-side JavaScript code to ensure that the server can properly interpret the type of media being received.

For guidance, you can refer to the AngularJs documentation, which provides a helpful example:

var req = {
 method: 'POST',
 url: 'http://example.com',
 headers: {
   'Content-Type': 'application/json'
 },
 data: { test: 'test' }
}

$http(req).then(function(){...}, function(){...});

I recommend examining the request within the network tab of your browser's devtool to ensure that the content-type is set as application/json.
