Guide on sending a string as a response to an HTTP request

In my Maven application, I have implemented a PUT HTTP request mapped to a specific function using the Spring Framework. The goal is to perform some internal checks and then send a text response. Subsequently, I need to trigger this request from AngularJS and store the received response in a variable within the AngularJS controller. Below is an example of what I have attempted:

@RequestMapping(path="/play", method={RequestMethod.POST}, produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
public String someFunction(){
    //...
    return "some text";
    }

$scope.getResponse = function(param1, param2...){

            $http.post("url..").then(
                    function(response){
                        $scope.response = response.data.response;
                        console.info('success');
                    },
                    function(response){
                        console.info('failure');
                    })

        }

The HTTP mapping is functioning correctly when accessed from a browser; however, the challenge lies in storing the textual response into an AngularJS variable within the controller.

Answer №1

It appears that $http is struggling to process the faulty JSON data in the response. We specified

produces = {MediaType.APPLICATION_JSON_UTF8_VALUE}
for the API, but we are actually sending plain text. This discrepancy is causing it to trigger the failure handler.

Try updating the media type to MediaType.TEXT_PLAIN_VALUE and test to see if it resolves the issue...
